There are super foods with
healing powers that need to be included in a healthy diet. Many of
these foods we know from folk lore, but now there is scientific
evidence that explains what makes these specific foods, "super foods
that heal." People do not need to understand everything about
individual nutrients in order to consume nutritionally adequate and
well-balanced diets. Even though the current understanding of
nutrition, health and disease has advanced well beyond nutrient
deficiencies, there is still much that is not known, and probably never
will be known, about the relationships between diet and health.
Fortunately, however, with a bit of common sense, people can still be
well nourished even though the understanding of nutritional science may
be incomplete.
For example, research efforts exploring the possible protective effects
of phytochemicals against various forms of chronic diseases have often
shown an association with the consumption of various foods rich in
these compounds, but not with specific phytochemicals themselves. There
are several possible explanations for this, including: the specific
phytochemicals being investigated may not be the ones that have an
effect; the effects of individual phytochemicals may be additive; and
it may be the interaction of two or more phytochemicals and nutrients
that produces an effect. Since the understanding of nutrition science
and the complex functions and interactions of the many vitamins,
minerals, macronutrients and phytochemicals contained in food is still
so incomplete, it is important that a rational and time-tested approach
be taken to the promotion of good nutrition. It is also important to
continue emphasizing the benefits of nutrient-dense foods, such as
citrus fruits, and to recognize that the consumption of whole foods and
natural juices is preferred over the consumption of individual
nutrients that have been isolated from food and then consumed as
dietary supplements. Focusing on single nutrients, instead of foods and
the total diet, does not constitute a healthful approach to good
nutrition.
As
nutritionists and public health specialists learn more about the
relationship between diet and health, the importance of balanced and
varied dietary intakes becomes ever more evident. Accordingly, there is
an increasing emphasis on promoting high levels of fruit and vegetable
intakes among most population groups.

ARTICHOKE Go back to the food list
Artichokes are low in calories,
with only 60 calories for one medium cooked globe and fat-free. It is a
natural diuretic, a digestive aid, and provides nutrition to
health-promoting bacteria in the intestinal tract. Some studies suggest
that fresh artichokes help control blood sugars in diabetics and lower
cholesterol levels thus warding off arteriosclerosis. Although
artichokes have a high amount of natural sodium, they are still lower
than most processed foods, and are also good sources of fiber,
potassium and magnesium. Some claim an extended period of eating
artichokes when in season will result in a cleaning and detoxification
of the body.
Don't let the thorny leaves of the artichoke discourage you. Within
this member of the thistle family lies a treasure for the palate and a
boon to the body. Spring is prime time for artichokes.
The ancients considered artichokes to have many benefits. Artichokes,
including leaves, were thought to be an aphrodisiac, a diuretic, a
breath freshener and even a deodorant. Decoctions of artichoke leaves
have been used as blood cleansers, cholerics, to improve bile
production and secretion and to detox the liver and the skin. The new
information about phytochemicals contained in vegetables and fruits is
confirming some of these ancient claims. Research is now underway to
determine the phytochemicals in artichokes, and work continues to
define the role these phytochemicals play in maintaining good health
and preventing disease.
- Current research is showing benefits to the liver from
cynarin, a compound found in the artichoke's leaves. Silymarin is
another compound found in artichokes that has powerful anitoxidant
properties and may help the liver regenerate healthy tissue.
- Artichokes are nutrient dense, so, for the 25 calories in a medium artichoke, you're getting 16 essential nutrients!
- Artichokes provide the important minerals magnesium, chromium,
manganese, potassium, phosphorus, iron and calcium. For example, that
25 calorie artichoke provides 6% of the Recommended Daily Value of
phosphorus, 10% of magnesium, 8% of manganese, 10% of chromium, 5% of
potassium, 4% of iron and 2% of calcium and iron.
- In addition to all these important minerals, artichokes are a good
source of fiber (12% of the RDV), vitamin C (10% of the RDV), and
folate (10% of the RDV).
- Artichokes are low in calories and sodium, have no fat and no cholesterol.
All this means that artichokes, as a part of a well balanced,
high-fiber diet, can help reduce the risk of certain types of heart
disease, cancers and birth defects.

AVOCADO Go back to the food list
But cut one open and you'll taste
why avocados have entranced diners since emerging from Central America
thousands of years ago.
Satiny, silky, sensuous, smooth -- all the adjectives that avocado
growers and promoters use for the homely fruit apply.
Indeed, avocados are sort of like a creamy dairy product that grows on
trees. They contain a surprising amount of fat -- about 15 grams per
half -- but fortunately almost all of that is the monounsaturated fat
(the same kind found in olive oil) that is thought to be good for the
heart. They're also loaded with potassium, fiber and disease-fighting
nutrients. Known for their deliciously rich flavor, California avocados
are also rich in phytochemicals -- natural plant nutrients that help
protect against a variety of cancers and diseases. Research shows
that avocados rank highest in the following phytochemicals and
nutrients among the 20 most frequently consumed fruits:
- Lutein – protects against prostate cancer and eye disease such as cataracts and macular degeneration.
- Vitamin E -- a powerful antioxidant known to slow the aging
process and protect against heart disease and various forms of cancer.
- Glutathione – functions as an antioxidant like
vitamin E to neutralize free radicals that can cause cell damage and
lead to disease.
- Beta-sitosterol – lowers blood cholesterol levels. Avocados
contain four times as much beta-sitosterol as oranges, previously
reported as the highest fruit source of this phytochemical.
- Monounsaturated fats – heart-healthy fats proven to help lower LDL (bad) cholesterol and boost HDL (good) cholesterol.
- Folate – promotes healthy cell and tissue development. Folate is
especially important for woman of childbearing age as it helps protect
against birth defects.
- Potassium – helps balance the body’s electrolytes. Avocados contain 60 percent more potassium than bananas.
- Magnesium – helps produce energy and is important for muscle contraction and relaxation.
- Fiber – lowers cholesterol and reduces risk of heart attack.
Many people are surprised to learn
that avocados are a fruit. They love the taste of avocados but do not
realize they are so rich in nutrients and phytochemicals. The avocado’s
unique nutrient profile makes them a stand out among commonly eaten
fruits.

BARLEY Go back to the food list
For many centuries humans have
used the barley plant (both the seeds and leaves) as food and medicine.
A source for B vitamins, vitamin E, and folic acid, barley seeds are
also ground into flour for baking or processed for use as a cereal.
Malt sugar, another common derivative of barley is made and used as a
natural laxative. Many people associate barley with the making beer,
but in other parts of the world it is a primary grain for food. In
Asia, barley seeds are fermented and added to soybeans, salt, and
seaweed for flavoring food.
For medical use barley is being researched for its ability to treat
diabetes, high cholesterol, and obesity. Some evidence suggests that
barley seed products in the diet may improve blood sugar levels in
individuals with diabetes, possibly because the fiber in barley seeds
delays stomach emptying and slows down the absorption of carbohydrates
from foods. Like oatmeal, barley seeds contain both soluble and
insoluble types of fiber that may help to lower cholesterol. Studies
have shown that individuals with barley in their diet experienced
reductions in their total cholesterol, low-density lipoprotein (LDL,
the "bad" cholesterol), and triglyceride levels. Additionally, barley
may assist in weight loss in that it acts as an appetite suppressant
making people feel like they have eaten more than they really have.
Barley seeds may also protect against colon cancer.
- Fiber - Barley is a good source of both soluble and
insoluble fiber. At a time when consumers are being encouraged to
increase fiber and grain intake, barley foods or barley components
added to other foods are a useful way to meet nutritional goals.
- One of the theories for the hypocholesterolemic effect is that the
soluble fiber becomes viscous in the intestinal tract, thus interfering
with the absorption of dietary cholesterol and fat.
- Tocotrienols - Barley has high concentrations of
tocotrienols, compounds which act as antioxidants, and are capable of
reducing serum LDL-cholesterol (one of the risk factors in
cardiovascular disease). Tocotrienols act by repressing the activity of
the first rate-limiting enzyme (HMG-CoA Reductase) in the liver, thus
reducing cholesterol synthesis.
- Beta-glucan - Beta-glucans are carbohydrates distributed
throughout the grain, with slightly higher concentrations in the outer
layers of the kernel. "Waxy" barley varieties are higher in
beta-glucans than other barleys. High beta-glucan levels in the waxy
barley was believed to be one of the reasons for the improved blood
glucose and lipid levels among diabetics in the clinical trial at the
University of Alberta.
Barley is available in many forms: flour, flakes, and pot and pearl
barley. It is easily added to the diet by baking with it, adding it to
casseroles and soups, and using in porridge. It is an extremely
versatile grain.

BEANS - LEGUMES Go back to the food list
Legumes, also known as dried beans
and pulses, are the edible seeds that grow in pods on annual plants,
bushes, or vines of the Leguminosae family. The seeds can be eaten
fresh, sprouted, dried and ground into flour, or prepared in countless
other ways. Legumes are often cooked in combination with grains,
because when the amino acids they contain are combined this way they
provide complete protein. Leading members of the legume family include
beans (Phaseolus), lentils (Lens), and peanuts (Arachis). Beans are a
Nutritional Power House When separating the "haves" from the "have
not's" on the playing field of nutrition, beans line up as first-string
all-stars. Beans are found in two places on the USDA's Food Guide
Pyramid - with high-protein foods such as meat, eggs, poultry and fish,
and also with vitamin-rich vegetables. The double dose of nutrition
packed into beans make them a "must have" in the daily diet.
- Beans
are an extremely beneficial component in all diets because they
are high in complex carbohydrates, protein and dietary fiber, low
in fat, calories and sodium, and completely cholesterol-free. As
little as a half-cup of beans added to the daily diet can be very
helpful in reaching important nutrition goals.
- Protein
Beans are an excellent, non-fat source of protein. Just one cup
of beans provides as much as 16 grams of protein.
- Beans are loaded with complex carbohydrates - the nutrient that
provides energy to the muscles and brain. Just one cup of beans
can provide 15 percent of the carbohydrates needed daily. Plus,
beans have the best type of carbohydrate for maximum energy -
low or moderate glycemic index carbohydrates.
Beans and other carbohydrates with a low to moderate glycemic
index have the unique ability to provide energy over a longer
period of time by being slowly released into your bloodstream
to provide sustained energy. A benefit for diabetics.
- Beans
are one of the best sources of dietary fiber, containing both
insoluble and soluble fiber. Insoluble fiber, generally thought
of as "roughage" that moves quickly through the digestive system,
is important in our diets because it helps promote a healthy digestive
tract and can reduce the risk of some types of cancer. During
digestion, soluble fiber forms a gel-like substance, which helps
the body handle fats, cholesterol and carbohydrates. Soluble fiber
plays a role in helping to lower blood cholesterol levels, one
of the main risk factors for the development of cardiovascular
disease. A high-fiber diet helps control diabetes
and maintain healthy blood glucose levels.
- Calcium
The
recommended calcium intake for adults is 1,000 mg per day. A half-cup
of beans provides as much as eight percent of the recommended
daily allowance for calcium. Calcium is necessary to maintain
bones and help prevent osteoporosis, a decrease in bone density
that can lead to fractures and disability.
- Potassium
Beans contain an abundance of potassium, which may help reduce
your risk of high blood pressure and stroke. Just one-half
cup of cooked dry beans contains as much as 480 mg of potassium.
Plus, dry-packaged beans are naturally low in sodium, with no
more than 5 mg of sodium in a one-half cup serving.
- Folate an important B vitamin that provides
many health benefits. Of all foods, dry beans
are the best source of folate. Cooked dry beans
provides, on average, 264 mcg of folate. Studies show that folate may help reduce the risk of certain
birth defects, like spina bifida (a potentially crippling defect
in which the spinal cord is not completely encased in bone)
and anencephaly (a fatal defect in which a major part of the
brain never develops).

BLUEBERRIESGo back to the food list
With flavors that range from
mildly sweet to tart and tangy, blueberries are nutritional stars
bursting with nutrition and flavor while being very low in calories.
Blueberries are at their best from May through October when they are in
season. Blueberries are literally bursting with nutrients and flavor,
yet very low in calories.
Recently, researchers at Tufts University
analyzed 60 fruits and vegetables for their antioxidant capability.
Blueberries came out on top, rating highest in their capacity to
destroy free radicals. Packed with antioxidant phytonutrients called anthocyanidins,
blueberries neutralize free radical damage to the collagen matrix of
cells and tissues that can lead to cataracts, glaucoma, varicose veins,
hemorrhoids, peptic ulcers, heart disease and cancer.
Anthocyanins, the
blue-red pigments found in blueberries, improve the integrity of
support structures in the veins and entire vascular system.
Anthocyanins have been shown to enhance the effects of vitamin C,
improve capillary integrity, and stabilize the collagen matrix (the
ground substance of all body tissues). They work their protective magic
by preventing free-radical damage, inhibiting enzymes from cleaving the
collagen matrix, and directly cross-linking with collagen fibers to
form a more stable collagen matrix.
Visionary Fruit Extracts of bilberry
(a variety of blueberry) have been shown in numerous studies to improve
nighttime visual acuity and promote quicker adjustment to darkness and
faster restoration of visual acuity after exposure to glare. This
research was conducted to evaluate claims of bilberry's beneficial
effects on night vision made by British Air Force pilots during World
War II who regularly consumed bilberry preserves before their night
missions.
Better Brain with Blueberries. In animal studies, researchers
have found that blueberries help protect the brain from oxidative
stress and may reduce the effects of age-related conditions such as
Alzheimer’s disease or dementia. Researchers found that diets rich in
blueberries significantly improved both the learning capacity and motor
skills of aging rats, making them mentally equivalent to much younger
rats.
|
BROCCOLIGo back to the food list
Recent research indicates that
Broccoli contains a substance called Sulforaphane that has been shown
in animal studies to dramatically reduce the number, size, and
reproduction of malignant tumors, as well as delay the onset of these
tumors. This appears to relate directly to cancer risk in humans,
particularly in breast, stomach, colon, rectal, and lung cancers, and
it is believed to be a powerful preventative for these diseases. It is
also rich in fiber, carotenoids, and vitamin A, vitamin C and vitamin
K, (which is a known stomach and colon cancer preventative).
Due to its high levels of vitamin
C, beta carotene, and fiber, Broccoli is a powerful antioxidant that is
believed to prevent damage to cells caused by free radicals, which are
believed to be a factor in cancers, Alzheimer's disease, heart disease,
arthritis, and in the aging process itself, suggesting that a diet high
in these substances may prevent or at least minimize the effects of
these diseases.
Broccoli is a powerful
anti-carcinogen, since it stimulates the body to produce its own
cancer-fighting substances. But broccoli doesn't stop there; it can
also help prevent cataracts, heart disease, arthritis, ulcers, and
viruses. The best way to prepare and eat broccoli is to steam it or eat
it raw.

BRUSSEL SPROUTSGo back to the food list
You either hate 'em or you love
'em. You can buy them loose and they'll be good, but if you can find
them on the stalk, that is the way to get them at their very best
because they are still pulling nutrients from the stalk. Brussels
sprouts are the cabbage variety BRASSICA OLERACEA GEMMIFERA. The genus
BRASSICA includes 40 or more species including cabbage, broccoli,
cauliflower, collards, kale, kohlrabi, pe-tsai, rape, rutabaga and
turnips to name a few. When selecting Brussels sprouts on the stalk,
make sure the stalk is green and that the Brussels sprouts are also
green, free from any yellowing whatsoever. When selecting them loose in
bulk, larger is not always better as smaller sprouts are usually milder
and sweeter. Fresh sprouts can be sautéed in extra virgin olive oil
with a couple cloves of garlic, or used in soups or stews. Always cook
them al dente for the best flavor and to retain the nutritional value.
Cooked sprouts are good sprinkled with lemon juice and nutmeg, seasoned
with mustard and dill, or combined with cooked chestnuts and tossed
with margarine. Very young, tender sprouts can be eaten raw for
dipping. A tip to keep them from smelling up the kitchen when you cook
them is to add some celery to the water.
Besides calcium and vitamins A, C, and E, Brussels sprouts are also a
good source of fiber, folic acid, and a variety of phytochemicals
including sulphoraphane, and indoles.

CABBAGEGo back to the food list
A diet rich in cruciferous
vegetables - cabbage, broccoli and Brussels sprouts - protects against
lung cancer. Many health claims have been made for cruciferous
vegetables, which contain high concentrations of isothiocyanates which
prevent lung cancer by increasing the excretion of tobacco-derived
toxins. The level of isothiocyanates in the body is controlled by two
genes - GSTM1 and GSTT1 - which determine how quickly they are
eliminated. People with inactive forms of these genes have higher
levels of isothiocyanates because they do not produce the enzymes that
break them down.
However, the protective effect only works in people who have inactive
versions of one or both of two specific genes - about half of the
population. Among those with the inactive genes who ate cabbage or its
relatives at least once a week, the risk of lung cancer was cut by a
third. The effect is seen only in smokers. Among non-smokers, in whom
lung cancer is rare, there was no difference between those who ate
cabbage and those who did not.
Cabbage is low in Saturated Fat, and very low in Cholesterol. It is
also a good source of Vitamin A, Thiamin, Riboflavin, Calcium and
Potassium, and a very good source of Dietary Fiber, Vitamin C, Vitamin
K, Vitamin B6, Folate and Manganese.
The Bad
This food is very high in Sodium, and a large portion of the calories in this food come from sugars.

CARROTSGo back to the food list
Carrots are an excellent source of
antioxidant compounds, and the richest vegetable source of the
pro-vitamin A carotenes. Carrots' antioxidant compounds help protect
against cardiovascular disease and cancer and also promote good vision,
especially night vision.
- Carotenoids and Heart Disease
High-carotenoid diets are associated with a reduced risk of heart
disease. In one study that examined the diets of 1,300 elderly persons
in Massachusetts, those who had at least one serving of carrots and/or
squash each day had a 60% reduction in their risk of heart attacks
compared to those who ate less than one serving of these
carotenoid-rich foods per day.
- VISION
Beta-carotene helps to protect vision, especially night vision. After
beta-carotene is converted to vitamin A in the liver, it travels to the
retina where it is transformed into rhodopsin--a purple pigment that is
necessary for night-vision. Plus beta-carotene's powerful antioxidant
actions help provide protection against macular degeneration and the
development of senile cataracts--the leading cause of blindness in the
elderly.
-
Carrots are by far one of the richest source of carotenoids
Just one cup provides 16,679 IUs of beta-carotene, more than 250% of
the RDA, and 3,432 REs (retinol equivalents), or roughly 686.3% the RDA
for vitamin A. High carotenoid intake has been linked with a 20%
decrease in postmenopausal breast cancer and an up to 50% decrease in
the incidence of cancers of the bladder, cervix, prostate, colon,
larynx, and esophagus. Extensive human studies suggest that a diet
including as little as one carrot per day could conceivably cut the
rate of lung cancer in half. Scientists now think that carrots'
protective effects are the result of a team effort among several
substances abundant in carrots, including alpha-carotene--another, less
publicized carotenoid. A recent National Cancer Institute study found
lung cancer occurrence was higher in men whose diets did not supply a
healthy intake of alpha-carotene.
- Carotenoids and Blood Sugar
Intake of foods such as carrots that are rich in carotenoids may be
beneficial to blood sugar regulation. Research has suggested that
physiological levels, as well as dietary intake, of carotenoids may be
inversely associated with insulin resistance and high blood sugar
levels.
- Falcarinol in Carrots Protects against Colon Cancer
Although best known for their high content of beta carotene, carrots
also contain a phytonutrient called falcarinol that may be responsible
for the recognized epidemiological association between frequently
eating carrots and a reduced risk of cancers.
- Protection against Emphysema
A common carcinogen in cigarette smoke, benzo (a) pyrene, induces vitamin
A deficiency. A diet rich in vitamin A can help counter this effect,
thus greatly reducing emphysema. Vitamin A's protective effects may
help explain why some smokers do not develop emphysema. The
implications are that those who start smoking at an early age are more
likely to become vitamin A deficient and develop complications
associated with cancer and emphysema. And if they have a poor diet,
forget it. Protect yourself by making sure the foods rich in vitamin A
(carrot's beta-carotene is converted in the body into vitamin A) are a
daily part of your healthy way of eating.

CHERRIESGo back to the food list
Sweet
cherries Nutritionally speaking, their benefits are well valued: good
source of the antioxidant, vitamin C and fiber; low in fat, including
saturated fat; and sodium- and cholesterol-free. In any meal or snack,
a serving of sweet cherries contributes good nutrition to any healthy
eating score, with a modest amount of calories. Great for
fitness-minded consumers!
Today's research is stepping beyond
nutrients to uncover the phytonutrient story of sweet cherries--and how
these bioactive nonnutritive plant substances contribute to health
promotion and disease prevention.
Sweet Cherries: Their Phytonutrient 'Score'
What's in sweet cherries? Although data on the phytonutrient
composition is incomplete, research evidence has identified significant
levels of phenolic compounds and other phytonutrients with antioxidant
capacity.
- One
measure of antioxidant capacity in food is its ORAC (Oxygen Radical
Absorbance Capacity) score. Cherries are among the ten highest ORAC
fruits that are reported in tests by USDA's Agricultural Research
Service (ARS). The ORAC score of sweet cherries is high--580 (for about
3.5 ounces)-- similar to many citrus fruits, but significantly less
than berries; ARS reports a general score for cherries of 670. Studies
suggest that eating plenty of high-ORAC foods can raise the antioxidant
power of blood 10 to 25 percent. (Note: besides antioxidant substances,
other plant substances or combinations of plant substances may also
account for the benefits of high ORAC foods.)
- Phenols
Because of their antioxidant activity, phenolic compounds in fruits and
vegetables have generated a great deal of interest. Phenols, including
flavonoids, protect body cells against ('anti-') the damage caused by
oxygen ('oxidation') that's released as a by-product of energy
metabolism. A small amount of released oxygen becomes part of highly
reactive free radicals, which attack and damage body cells to get the
missing electron they need. Antioxidants protect by contributing an
electron of their own. In so doing, they neutralize free radicals and
help prevent cumulative damage to body cells and tissues.
Much of the total antioxidant activity of fruits and vegetables is
related to their phenolic content, not only to their vitamin C content.
Research suggests that many flavonoids are more potent antioxidants
than vitamins C and E.
- Quercetin
Cherries are relatively high in a flavonoid called quercetin. A serving
of processed cherries has about 3 milligrams of quercetin for 3.5
ounces of processed cherries. Because processing concentrates the
quercetin, processed cherries have about twice the amount of quercetin
as fresh cherries.
Research on quercetin--specifically on quercitrin and
isoquercitrin--has revealed that the profile of these flavonoids varies
among different types of cherries. Sweet cherries and tart Montmorency
cherries are similar in their isoquercitrin content; however, tart
cherries have a significantly higher amount of quercetin. Quercetin,
the most commonly consumed flavonoid, is reported to have a strong
antioxidant capacity. It has been studied for its potential health
benefits, particularly for its relation to blood clotting and its role
in reduced risk for heart attack and stroke.
- Anthocyanins
Fruit pigments, which account for the varying colors of cherries and
berries, guava and citrus, have been described as a potential 'mother
lode in a gold mine of antioxidants': among the pigments, the rich red
hue of sweet cherries contributed by anthocyanins. Cherries have a high
ORAC score, which seems to be correlated with their anthocyanin
content. Not surprisingly, the darker the cherry, the higher the
anthocyanin content. The range is about 80 to 300 milligrams of
anthocyanins in 3.5 ounces (100 grams) of pitted dark cherries,
compared with 2 to 40 milligrams of anthocyanins in the same amount of
light-colored cherries.
Research suggests that processing degrades the anthocyanin content of
cherries, reporting a loss of more than 50 percent of anthocyanins in
cherries during 6 months of frozen storage.
- Ellagic Acid
Cherries contain yet another phenolic compound, ellagic acid. Found in
many fruits, ellagic acid may help the growing plant fight microbial
infection; it's also part of cancer-preventing drugs.
- Perillyl Alcohol
Another classification of phytonutrients, terpenes (which include the
well-known carotenoids) also work as powerful antioxidants.
Monoterpenes are found in the essential oils of fruits; cherries are
reported to be a significant source of the monoterpene perillyl
alcohol. Some dietary monoterpenes are reported to show antitumor
activity.
- Melatonin You've
seen melatonin tablets, sold on the supplement shelf, perhaps in a
500-microgram tablet with a cherry flavor. Did you know: melatonin is
found naturally in food as well! In fact, cherries are a significant
source, with tart cherries supplying more than sweet cherries. For 100
grams (about 3.5 ounces) of dried cherries, tart Montmorency cherries
contain 27 milligrams of melatonin compared with 7 milligrams in sweet
cherries. Although known for its potential as a sleep enhancer, it's
reported that melatonin also possesses high antioxidant activity,
perhaps being more effective than vitamin E in scavenging peroxyl
radicals, one type of free radical.
Unlike antioxidant vitamins, melatonin is soluble in both water and fat, perhaps enhancing its capacity as an antioxidant.
- Beta-sitosterol. Cherries contain beta-sitosterol--a phytosterol, or plant sterol,
found in fruits, such as avocados, bananas, apples, cantaloupes,
grapes, and plums, as well as cherries. High phytosterol intake may be
linked to lower blood cholesterol levels.
- Fiber
An indigestible carbohydrate, fiber offers a functional health benefit,
as well. Like other fruits, cherries supply fiber: 10 cherries contain
about 1.6 grams of fiber (1.1 grams of insoluble fiber and 0.5 grams of
soluble fiber.) For healthy adults, 20-35 grams of fiber daily are
advised. A high-fiber diet is linked to reduced risks for many health
problems, including some cancers and heart disease
|
CHILI PEPPERSGo back to the food list
Why does 75% of the world’s population include chilies in their diets?
We know the Pueblo Indians and Spanish
settlers valued chilies as a natural digestive, herbal medicine and
disinfectant for wounds. Capsaicin found in chilies has provided relief
for people suffering from arthritis, acne, motion sickness, ulcers, and
more. Capsaicin has been associated with many cures that include
lowering blood pressure, reducing cholesterol and warding off strokes
and heart attacks, speeding up metabolism, treating colds and fevers,
preventing cancer and pain control. Capsaicin is a flavorless, odorless
chemical concentrated in the veins of chiles and peppers.
Reduced Blood Clot Incidence
Long used as a food spice and an aid to digestion, red chilies or
cayenne peppers were once thought to aggravate stomach ulcers. This
fear has been discounted by researchers who became excited by studies
that indicated that capsicum could help prevent the formation of
dangerous blood clots. Now new research is focusing on this spices
ability to act as an anti-inflammatory agent, and aid in controlling
pain. Researchers in Thailand first noticed that people who consume
large amounts of red chili peppers experienced a lower incidence of
thrombo-embolism, or potentially dangerous blood clots. Scientists then
looked at the medical records of countries where hot spicy foods were
regularly consumed, and found that people who eat a diet high in red
peppers experience a much lower incidence of blood clotting diseases.
Scientists have now concluded that capsicum does indeed possess
fibrinolytic activity, meaning that it is able to break down blood
clots.
Pain Relief
In addition to preventing the formation of blood clots, researchers
have also discovered that a topically applied cream containing capsicum
could help control some types of chronic skin pains. Now available in
the form of a prescription drug, capsicum ointment is applied to the
skin to aid in controlling the pain associated with herpes zoster, also
known as shingles, as well as neuralgia and postoperative amputation
trauma. The active ingredient in Capsicum is a compound called
capsaicin that functions to deplete 'substance P', which is involved in
the transmission of pain from the skin to the spinal cord. By blocking
substance P, capsaicin acts as a dramatic and long-lasting anesthetic
bringing relief to almost 75 percent of patients tested with the cream.
It can take as long as three days from first application to begin to
deplete substance P from the peripheral nerves. Taken internally to aid
digestion, red peppers should be consumed slowly to avoid distress. Be
careful to avoid getting Capsicum products in the eyes, as this can be
extremely painful.
Reduced Cancer Death Rate
In the countries where diets are traditionally high in capsaicin, the
cancer death rates for men and women are significantly lower than they
are in countries with less chili pepper consumption (World Health
Organization statistics). When capsaicin was administered to rats
receiving carcinogenic agents, the incidence of certain tumors was
decreased over controls. Capsaicin has been found to preferentially
inhibit the growth of cancer cells in laboratory studies.

- Chile is an excellent source of beta carotene, foliate, potassium, and vitamin E and is a very powerful decongestant.
- Chile helps to burn calories by increasing the metabolic rate.
- Chile contains very high amounts
of vitamin C, especially when raw. The later the chile is harvested,
the higher the vitamin C content.
- Chile is great for low sodium diets.
- Chile battles high cholesterol… cholesterol is absorbed through "plant tissue."

CINNAMON Go back to the food list
Cinnamon has a long history both
as a spice and as a medicine. It is the brown bark of the cinnamon
tree, which is available in its dried tubular form known as a quill or
as ground powder. The two varieties of cinnamon, Chinese and Ceylon,
have similar flavor, however the cinnamon from Ceylon is slightly
sweeter, more refined and more difficult to find in local markets.
Cinnamon’s unique healing abilities come from three basic types of
components in the essential oils found in its bark. These oils contain
active components called cinnamaldehyde, cinnamyl acetate, and cinnamyl
alcohol, plus a wide range of other volatile substances.
- Anti-Clotting Actions
Cinnamaldehyde (also called cinnamic aldehyde) has been well-researched
for its effects on blood platelets. The cinnaldehyde in cinnamon helps
prevent unwanted clumping of blood platelets. (The way it accomplishes
this health-protective act is by inhibiting the release of an
inflammatory fatty acid called arachidonic acid from platelet membranes
and reducing the formation of an inflammatory messaging molecule called
thromboxane A2.) Cinnamon's ability to lower the release of arachidonic
acid from cell membranes also puts it in the category of an
“anti-inflammatory” food that can be helpful in lessening inflammation.
- Anti-Microbial Activity
Cinnamon’s essential oils also qualify it as an “anti-microbial” food,
and cinnamon has been studied for its ability to help stop the growth
of bacteria as well as fungi, including the commonly problematic yeast
Candida. In laboratory tests, growth of yeasts that were resistant to
the commonly used anti-fungal medication fluconazole was often (though
not always) stopped by cinnamon extracts.
- Blood Sugar Control
Cinnamon may significantly help people with type 2 diabetes improve
their ability to respond to insulin, thus normalizing their blood sugar
levels. Both test tube and animal studies have shown that compounds in
cinnamon not only stimulate insulin receptors, but also inhibit an
enzyme that inactivates them, thus significantly increasing cells’
ability to use glucose. 1 gram per day (approximately ¼ to ½ teaspoon),
produces an approximately 20% drop in blood sugar; cholesterol and
triglycerides were lowered as well. When daily cinnamon is stopped,
blood sugar levels will begin to increase. Some scientists had been
concerned about potentially toxic effects of regularly consuming
cinnamon. New research shows that the potentially toxic compounds in
cinnamon bark are found primarily in the lipid (fat) soluble fractions
and are present only at very low levels in water soluble cinnamon
extracts, which are the ones with the insulin-enhancing compounds.
Research on cinnamon shows that by enhancing insulin signaling,
cinnamon can prevent insulin resistance.
- Cinnamon is a powerful antioxidant
When compared to six other antioxidant spices (anise, ginger, licorice,
mint, nutmeg and vanilla) and the chemical food preservatives (BHA
(butylated hydroxyanisole), BHT (butylated hydroxytoluene), and propyl
gallate), cinnamon prevented oxidation more effectively than all the
other spices (except mint) and the chemical antioxidants.
- Cinnamon's Scent Boosts Brain Function
Not only does consuming cinnamon improve the body’s ability to utilize
blood sugar, but just smelling the wonderful odor of this sweet spice
boosts brain activity!
- Calcium and Fiber Improve Colon Health and Protect Against Heart Disease
In addition to its unique essential oils, cinnamon is an excellent
source of the trace mineral manganese and a very good source of dietary
fiber, iron and calcium. The combination of calcium and fiber in
cinnamon is important and can be helpful for the prevention of several
different conditions. Both calcium and fiber can bind to bile salts and
help remove them from the body. By removing bile, fiber helps to
prevent the damage that certain bile salts can cause to colon cells,
thereby reducing the risk of colon cancer. In addition, when bile is
removed by fiber, the body must break down cholesterol in order to make
new bile. This process can help to lower high cholesterol levels, which
can be helpful in preventing atherosclerosis and heart disease. For
sufferers of irritable bowel syndrome, the fiber in cinnamon may also
provide relief from constipation or diarrhea
- A Traditional Warming Remedy
In addition to the active components in its essential oils and its
nutrient composition, cinnamon has also been valued in energy-based
medical systems, such as Traditional Chinese Medicine, for its warming
qualities. In these traditions, cinnamon has been used to provide
relief when faced with the onset of a cold or flu, especially when
mixed in a tea with some fresh ginger.

CITRUS FRUITSGo back to the food list
Nutritional and health benefits of citrus fruits
Citrus fruits have long been valued as part of a nutritious and tasty
diet. The favors provided by citrus are among the most preferred in the
world, and it is increasingly evident that citrus not only tastes good,
but is also good for people. It is well established that citrus and
citrus products are a rich source of vitamins, minerals and dietary
fiber (non-starch polysaccharides) that are essential for normal growth
and development and overall nutritional well-being. However, it is now
beginning to be appreciated that these and other biologically active,
non-nutrient compounds found in citrus and other plants
(phytochemicals) can also help to reduce the risk of many chronic
diseases. Where appropriate, dietary guidelines and recommendations
that encourage the consumption of citrus fruit and their products can
lead to widespread nutritional benefits across the population.
MORE THAN VITAMIN C: THE NUTRIENT CONTENT AND FUNCTIONS OF CITRUS
Citrus is most commonly thought of as a good source of vitamin C.
However, like most other whole foods, citrus fruits also contain an
impressive list of other essential nutrients, including both glycemic
and non-glycemic carbohydrate (sugars and fiber), potassium, folate,
calcium, thiamin, niacin, vitamin B6, phosphorus, magnesium, copper,
riboflavin, pantothenic acid and a variety of phytochemicals. In
addition, citrus contains no fat or sodium and, being a plant food, no
cholesterol. The average energy value of fresh citrus is also low,
which can be very important for consumers concerned about putting on
excess body weight. For example a medium orange contains 60 to 80 kcal,
a grapefruit 90 kcal and a tablespoon (15 ml) of lemon juice only 4
kcal (Whitney and Rolfes, 1999).
PREVENTION POTENTIAL OF CITRUS
There
is considerable evidence that citrus foods may help reduce the risk, or
retard the progression, of several serious diseases and disorders.
- Cardiovascular disease. It is
well accepted that a diet low in saturated fat and cholesterol and rich
in fruits and vegetables reduces the risk of heart disease.
Epidemiological studies have also shown a significant association
between vitamin C intake and protection against cardiovascular
mortality, but the precise mechanism of protection is still unclear.
One major culprit in the development of heart disease appears to be a
high level of oxidized low-density lipoprotein (LDL), the so-called bad
cholesterol. Significantly, a recent study has shown that high intakes
of vitamin C (500 mg/day) obtained from the juice of freshly squeezed
oranges, prevented a rise in the levels of oxidized LDL, even in the
presence of a high-saturated fat diet (Harats et al., 1998).
A low dietary intake of folate contributes to the decrease of plasma
folate and the raising of plasma homocysteine levels (Bloom, 1998;
Tucker et al., 1996). Homocysteine is a toxic agent for the vascular
wall and, when plasma levels rise above normal, there is an increased
risk of cardiovascular disease. An inverse dose-response relationship
has been identified for fruit and vegetable intake and plasma
homocysteine levels. Frequent consumption of folate-rich foods, such as
oranges and orange juice, tends to increase plasma folate levels and,
thus, lower homocysteine levels.
- Cancer
After numerous studies of fruit and vegetable intake and cancer
development, there is a consensus that consuming these foods has a
protective effect (Block, Patterson and Subat, 1992). However, it is
unlikely that one anticarcinogenic substance in particular is
responsible for the benefit. There is reasonable scientific support for
vitamin C's protective role in cancer. Many of the animal, cell culture
and human studies have suggested it has a positive effect. However,
epidemiological studies provide good evidence that protective effects
are more closely associated with the consumption of fruits and
vegetables rather than with the enormous levels of vitamin C often used
in cell culture and animal studies.
- Neural tube defects
During the first stage of pregnancy, adequate folate intake is critical
for reducing the risk of severe birth defects, namely spina bifida and
anencephaly. Public health recommendations in the United States include
the consumption of 400 mcg of folate per day for women of child-bearing
age (Centers for Disease Control and Prevention, 1992). Regular
consumption of citrus foods can help supply adequate folate and thus
reduce the risk of these birth defects.
- Anaemia
Vitamin C can increase the absorption of non-haem iron (the inorganic
iron form found in plant foods) two- to fourfold (Fleming et al.,
1998). The bioavailability of non-haem iron is much lower than that of
haem iron, which is found in foods of animal origin (Whitney and
Rolfes, 1999). Vegetarians and individuals who consume little meat and
animal products are at an increased risk of iron-deficiency, which can
progress to anaemia over time. Worldwide, anaemia is one of the most
serious nutrient-related public health problems, resulting in poor
growth, impaired psychomotor development, reduced physical performance
and decreased cognitive function. Consuming citrus fruits rich in
vitamin C can help prevent anaemia and its devastating consequences.
- Cataracts
Oxidation of the eye's lens plays a central role in the formation of
age-related cataracts. The role of dietary antioxidants, such as
vitamin C, in the aetiology of cataracts has been a recent focus of
research (Jacques et al., 1997). Lower cataract risk has been shown in
individuals with high blood concentrations or intakes of vitamin C and
carotenoids. There is now evidence to show that a high level of vitamin
C intake over the long term decreases the risk of cataract development.
Although epidemiological studies that measure past nutrient intake and
status suggest a protective effect from citrus, further studies are
needed to examine the long-term benefits of citrus fruit consumption
and cataract protection.

FLAX SEEDGo back to the food list
Benefits of Flax seed - Heart Disease/Cholesterol Lowering
Its high content of alpha linolenic acids has made the ancient flax
seed become our modern miracle food. Alpha linolenic acid is a type of
omega 3 fatty acid, similar to those found in fish such as salmon.
Benefits of flax seed as shown in many studies include lowering total
cholesterol and LDL cholesterol (the Bad cholesterol) levels. Other
benefits show that flax seed may also help lower blood triglyceride and
blood pressure. It may also keep platelets from becoming sticky
therefore reducing the chance of a heart attack.
Aside from alpha linolenic acid, flax seed is rich in lignan. Lignan is
a type phytoestrogen (antioxidant) and also provides fiber. Researches
reveal that lignan in flax seed shows a lot of promise in fighting
disease -- including a possible role in cancer prevention especially
breast cancer. It is thought that lignan metabolites can bind to
estrogen receptors, hence inhibiting the onset of estrogen-stimulated
breast cancer.
Recent studies also showed positive benefits of flax seed oil in IBD
(Crohn's Disease and Colitis). Flax seed oil seems to be able to heal
the inner lining of the inflamed intestines.
Moderately include flax seed in your diet. Indeed, a lot of food
products contain flax seed such as bread, cereal and bakery goods.

GARLICGo back to the food list
Benefits of Garlic - Heart Disease/Cholesterol Lowering
Besides the mythical acclaim for warding off vampires and other evil
spirits, garlic has a centuries-old reputation for its health and
healing qualities. Today, this plant ranks as our most popular herbal
cure-all. And it may indeed have some untapped medicinal potential.
An analysis of five studies, reported last year in the Annals of
Internal Medicine indicates, for example, that eating one-half to one
clove a day reduced cholesterol levels by 9%. Another study in
Circulation, the prestigious journal sponsored by the American Heart
Association, suggests that garlic may help maintain the elasticity of
aging blood vessels. (Blood vessels, like old rubber bands, lose their
stretchiness with time. This is why many elderly people have high blood
pressure.) In the Circulation study, the average garlic intake was
five, 100 milligram tablets (a little less than half a medium garlic
clove) a day.
Other studies have shown garlic may lower high blood pressure, retard
the growth of certain bacteria, reduce the risk of breast, stomach and
colon cancers, serve as a diuretic, and help in the long-term treatment
of intermittent claudication (restricted leg blood flow that causes
pain while walking).
Nevertheless, munching on garlic cloves or taking garlic supplements is
not now being advised by the American Heart Association or any other
national health organization. The reason is that appropriate
experimental studies have not been conducted -- that is, long-term
clinical trials where individuals are randomly assigned to consume or
not consume garlic. Of the 1,000 or so garlic and health investigations
to date (including those mentioned above) almost all are of the
observational or questionnaire type (epidemiological) studies. Gold
standard experimental studies are essential to prove the real value of
a substance.
Furthermore, aside from an antibacterial compound called allicin,
scientists do not know which of the many substances in garlic produce
beneficial effects. Until all this is clear, health organizations will
be reluctant to make any health recommendations for garlic.
In addition, there is little market control on garlic supplements. When
you purchase garlic pills, you can't be sure of exactly what you are
buying. These products, like other dietary supplements, are not viewed
as drugs by government regulators; therefore, they are not scrutinized
for content, purity or anything else so long as the manufacturers do
not make health claims on the package. Consequently, the content of the
pills can and does vary. One study found that the amount of garlic
ingredients released by different supplement brands varied by as much
as 18-fold.
Caution. If you regularly take medications such as aspirin or other
drugs that thin the blood, see your doctor before taking garlic
supplements. Garlic has anticoagulant properties.

GRAPESGo back to the food list
Benefits of Grapes
The substances in the grapes called flavonoids have been proven capable
of keeping your arteries free of disease-causing plaque. Now, a new
study says the lip-staining liquid also has the ability to increase the
antioxidants in your body while decreasing the level of free radicals.
Antioxidants are vitamins like C, E and A that trap free radicals,
which are potentially destructive molecules.
The flavonoids, which give grapes their color, also reduce production
of the free radicals, increase production of nitric oxide, which
inhibits clot formation, reduce the size of clots and inhibit platelet
activity.
Key benefits of grapes:
- Both
red and black grapes contain powerful antioxidants and resveratrol,
which helps to prevent both the narrowing and hardening of the arteries.
- Ellagic acid, which has anti-cancer properties, is also contained in grapes.
- Grapes have many health benefits, but have a high sugar content and should therefore be eaten in moderation.
- Grapes are a good source of potassium.

GREEN TEAGo back to the food list
Benefits of Green Tea
Green tea's popularity in the United States continues to grow.
Scientific information that suggests it is a rich, natural source of
antioxidants. Most of the green tea research to date has focused on
cancer prevention. During the 1980s populations studies found lower
rates of cancer in Asian populations who regularly consume green tea.
Since then, scientists have been trying to find out why green tea
drinkers are less likely to develop cancer, what specific green tea
components act to prevent cancer, and exactly how green tea works in
the human body. Scientifically important findings suggest that green
tea may prevent the following types of cancer in humans: bladder,
colon, esophageal, pancreas, rectum, and stomach. Information from both
animal and human studies suggests antioxidants in green tea may lower
cholesterol; reduce the risk of dying from heart disease, and control
blood pressure. In a 25-year study, tea drinkers consuming more than
8.5 oz. of tea each day had much less risk of dying and a lower rate of
first heart attacks than those who drank less tea. Men in the study
whose antioxidant intake was greatest had one-third the risk of death
from coronary heart disease. In another test tube study, scientists
report that antioxidants decrease blood cell clumping, which reduces
blood clotting and other risks that commonly happen before heart
attacks and strokes. Although these data are ground breaking, more
studies with humans are needed to establish the heart benefits from
drinking green tea. Scientists suggest green tea helps the liver in two
ways - by protecting liver cells and by triggering the immune system.
Green tea antioxidants have been shown to protect the liver against
toxins like alcohol and chemicals in cigarette smoke. Although the
scientific information about the effects of green tea on the liver is
limited, the early results look promising and should be studied in
greater detail in the future.

KALEGo back to the food list
Benefits of Kale
Nutritionally, kale is near the top
amongst vegetables. It's a real nutrition booster, with its high level
of beta carotene and plentiful amounts of vitamins C and E. These
antioxidants make it a good food to lower the risk of heart disease,
stroke and cataracts. Kale is also loaded with such minerals as
calcium, potassium, manganese and iron.
Additionally, kale is high in sulforaphane, which stimulates the body
to produce cancer-fighting enzymes. Sulfur compounds called
glucosinolates, which are found in generous amounts in cruciferous
vegetables like kale, are broken down into compounds called
isothiocyanates and indoles when the vegetable is chewed or cut. The
presence of vitamin C makes this process even more effective, as the
compounds are more readily available for the body's use.
Researchers believe kale's cancer-lessening ability stems from these
and many population compounds found in kale. Some surveys, experimental
testing, and several animal trials studies have found that eating kale
on a regular basis lowers the risk of different cancers.
Kale is also among the highest vegetable sources of chlorophyll, an immune system stimulant.
In the "Medical Value of Natural Foods," published in 1936, Dr W.H. Graves
wrote that kale is also effective in treating constipation, obesity,
acidosis, emaciation, poor teeth, pyorrhea, arthritis, gout, rheumatism,
skin diseases and bladder disorders.
|
LEEKSGo back to the food list
Benefits of leeks
Leeks, like garlic and onions, belong to a vegetable family called the
Allium vegetables. Since leek is related to garlic and onions, it
contains many of the same beneficial compounds found in these
well-researched, health-promoting vegetables.
Lower LDL Cholesterol While Raising HDL Cholesterol
A high intake of Allium vegetables has been shown to reduce total
cholesterol and LDL, or “bad” cholesterol levels, while at the same
time raising HDL, or “good” cholesterol levels. This can be very
important for preventing the development or progression of the blood
vessel plaques that occur in atherosclerosis and diabetic heart
disease. If these plaques grow too large or rupture, the result can be
a heart attack or stroke. Allium vegetables have also been shown to
lower high blood pressure, another risk factor for heart attack and
stroke.
Protection from Cancer
Regular consumption of Allium vegetables, as little as two or more
times a week, is associated with a reduced risk of prostate and colon
cancer. The research focused on colon cancer suggests that several of
the compounds found in these foods are able to protect colon cells from
cancer-causing toxins, while also stopping the growth and spread of any
cancer cells that do happen to develop.
Although leeks contain many of the same compounds as those active in
fresh garlic and onions, they contain them in smaller amounts. For this
reason, larger amounts of leeks may need to be eaten to obtain the
benefits provided by its Allium family cousins. Fortunately, the mild,
sweet taste of leeks makes this easy to do.
Stabilize Blood Sugar Levels
In addition to their unique properties as Allium family vegetables,
leeks also emerged from our food ranking system as a very good source
of manganese and a good source of vitamin B6, vitamin C, folate, and
iron. This particular combination of nutrients would make leeks
particularly helpful in stabilizing blood sugar, since they not only
slow the absorption of sugars from the intestinal tract, but help
ensure that they are properly metabolized in the body.
|
MANGOS Go back to the food list
Benefits of Mangos
Mangos really can make you feel better!
Beyond being delicious and rich in vitamins, minerals and
anti-oxidants, mangos contain an enzyme with stomach soothing
properties similar to papain found in papayas. These comforting enzymes
act as a digestive aid and can be held partially responsible for that
feeling of contentment.
Mango, both in its green and ripe form is a very good tenderizing agent
due to these same enzymes, therefore ideal to include in any marinade
In India they use a sour mango powder containing ground up green mangos
called Amchur, both as a seasoning and tenderizing aid.
We all know the importance of fiber in our diets. Mangos are high in
fiber, but low in calories (approx. 110 per average sized mango)
Research has shown that dietary fiber has a protective effect against
degenerative diseases, especially with regards to the heart; may help
prevent certain types of cancer, as well as lowering blood cholesterol
levels. An average sized mango can contain up to 40% of your daily
fiber requirement. For those of you who are physically active, whether
working out or constantly on the go, mangos are also a great way to
replenish that lost potassium and are rich in anti-oxidants, potassium
and fiber.
Mangos are an excellent source of Vitamins A and C, as well as a good source of Potassium and contain beta carotene.

NUTS and SEEDS Go back to the food list
Benefits of Nuts and Seeds
Nuts are seeds that are covered with a hard shell. Most are the seeds
of trees, but the seeds of a few other plants that are not strictly
nuts will also be considered here as they can be conveniently
classified with nuts for culinary purposes.
Nuts can be used in many ways. Whole, flaked and ground nuts and nut
butters are widely available. A classic savoury is nut roast and many
vegetarian cook books give a recipe for one, which can be endlessly
varied with different herbs and flavorings and different combinations
of nuts and cereals. Nuts can be added to sweet dishes, cakes and
biscuits, and nut butters can be added to soups and stews to thicken
them.
Nutrition
Nuts in general are very nutritious, providing protein and many
essential vitamins, such as A and E, minerals, such as phosphorous and
potassium, and fiber. Nuts are also high in carbohydrate and oils, so
shouldn't be eaten in excess. Whereas pulses all belong to the legume
group of plants, nuts come from a variety of different plant groups, so
the nutritional content is more varied too. A brief description of
individual varieties is given below, together with the main nutrients
they contain.
Storage
Nuts should be stored in cool, dry conditions in airtight containers
away from the light. Because of their high fat content, many of them
benefit from storage in the fridge or freezer to deter rancidity.
Nuts
- Almonds
Probably originated in the Near East but now grows in Southern Europe,
Western Asia, California, South Australia and South Africa. Almond oil
is used for flavoring and for skin care preparations and is extracted
from the kernel of the Bitter Almond. The Sweet Almond is grown for
nuts for eating and has the largest share of the nut trade world-wide.
Almond flour is available and it is possible to make a nutritious nut
milk from almonds.
Almonds are particularly nutritious;
100g contain 16.9g protein, 4.2mg iron, 250mg calcium, 20mg vitamin E, 3.1mg zinc and 0.92mg vitamin B2.
- Brazils
A native of South America. The nuts grow inside a hard, woody fruit
rather like a coconut shell which has to be broken open to expose the
12-24 nuts inside. Brazils are high in fat, which causes them to go
rancid very quickly, and protein.
100g of brazils contain 12g protein, 61g fat, 2.8mg iron, 180mg calcium, 4.2mg zinc.
- Cashews
Native to America but now grown extensively in India and East Africa.
It will withstand rather drier conditions than most other nuts. The nut
grows in a curious way on the tree, hanging below a fleshy, apple-like
fruit. It is related to the mango, pistachio and poison ivy. High in
protein and carbohydrate,
100g cashews contain 17.2g protein, 60 micrograms vitamin A, 3.8mg iron.
- Chestnuts
The sweet chestnut is a native of South Europe but is planted elsewhere
extensively for both nuts and timber. The nuts can be used in soups,
fritters, porridges, stuffings and stews, as well as being roasted or
boiled whole. Available fresh (in autumn), dried, canned - whole or
pureed, or ground into flour. Dried chestnuts need soaking for at least
1-2 hours and boiling for 45-60 minutes, fresh need boiling for 40
minutes before being peeled. Preserved in syrup they become the famous
delicacy, Marron-glace. High in starch, but low in protein and fat,
100g chestnuts contain 36.6g carbohydrate, only 2g protein (the lowest of all nuts) and 2.7g fat.
- Coconuts
The coconut palm is common in tropical regions all over the world. The
nut is covered in a fibrous outer coating on the tree and all parts of
the tree are useful, the trunks for timber, the leaves for thatch, the
fibrous husk produces coir - the starting material for ropes and
coconut matting - and the nuts are used for food. Unripe nuts contain
coconut milk. The nutmeat can be eaten fresh or dried (desiccated or
flaked coconut) and is also available in blocks of creamed coconut. A
valuable oil is also extracted from the nut meat and used for cooking
(although it is very high in saturated fat), margarines, soaps and
detergents.
100g fresh coconut contains 3.2g protein and 36g fat, desiccated contains 5.6g protein and 62g fat.
- Hazels
Hazel, also called Cob, is a common wild tree in Europe and Asia and
its nuts have been eaten by humans since earliest times. The cultivated
varieties are bigger and the filbert is a similar but bigger species
from SE Europe. Used in sweet and savoury dishes, they are available
whole, ground and flaked, or made into oil and nut butter.
100g hazel nuts contain 7.6g protein, and they are lower in fat than most other nuts.
- Macadamia Nuts
A native of NE Australia now also grown commercially in Hawaii.
Notoriously difficult to extract from their shells, they are expensive
but have a delicious creamy flavor and crunchy texture. Low in
carbohydrate, but quite high in fat,
100g Macadamia nuts contain 7g protein and 40mg calcium.
- Peanuts
Also known as groundnuts or monkey nuts, peanuts are actually legumes.
Of South American origin, it's now an important crop all over the
tropics and southern USA. It gets its name groundnut because as the
pods ripen, they are actually forced underground. Peanuts are high in
protein and contain 40-50% oil. The oil is used in cooking, as salad
oil, in margarines and the residue is fed to animals. Whole peanuts can
be eaten raw or roasted or made into peanut butter (look out for brands
which do not contain hydrogenated oils, which are highly saturated). As
they are usually inexpensive, they can be mixed with other kinds of
nuts to bring down the cost, while still maintaining flavor and good
nutrition.
100g peanuts contain 24.3g protein, 2mg iron and 3mg zinc.
- Pecans
A native of N America where it is used extensively in ice cream, cakes,
nut bread and confectionery. The flavor is rather like a mild, sweet
walnut.
100g
pecans contain 9.2g protein, a very high fat content of 71.2g, 130
micrograms vitamin A (also very high), 2.4mg iron and 73mg calcium.
- Pine Nuts
These are the seeds of the Stone Pine, a native of the Mediterranean
region, but the seeds of various other pines are eaten in various parts
of the world including the seeds of the Korean Pine or North American
pinion tree. They are very difficult to harvest, hence their cost. They
are vital for pesto sauce, and are delicious lightly toasted. They
become rancid very easily and should be stored in the fridge or
freezer.
100g pine nuts contain 31g protein, the highest of the nuts and seeds.
- Pistachios
Native to the Near East and Central Asia but has long been cultivated
in the Mediterranean region and more recently in the Southern US. The
kernels are green and are prized as much for their ornamental color as
for their flavor. Also sold roasted and salted in their shells. They
are more expensive than most other nuts.
100g pistachios contain 19.3g protein, 14mg iron, 140mg calcium.
- Walnuts
The walnut is native to SE Europe and West & Central Asia but is
now grown in the UK, California and China as well. It is grown for
timber as well as its nuts. Walnut oil has been used for centuries in
the preparation of artists' paints. The black walnut is a native of
North America, introduced into Britain in the 17th century. The
butternut is also from North America. These two have much thicker
shells than European walnuts.
High in fat, they go rancid very quickly and should be stored in the fridge or freezer.
100g walnuts contain 10.6g protein and 2.4mg iron.
Seeds
- Pumpkin
Can be eaten raw or cooked in either sweet or savoury dishes. Delicious
toasted and sprinkled, while hot, with soya sauce and served on salads.
They are rich in protein, iron, zinc and phosphorous.
100g pumpkin seeds contain 29g protein, 11.2mg iron and 1144mg phosphorous.
- Sesame
Of African origin but now common in tropical and sub-tropical Asia. An
oil is extracted from the seed and used for cooking, salad oil and
margarines. It is also available as toasted sesame oil for oriental
cooking. The whole seeds can also be eaten and are most often seen as a
decoration on cakes, confectionery etc. Sesame seed paste, tahini, is
used in many dishes e.g. hummus. Halva, a sweet made from sesame seeds
is often found in health food shops.
A good source of protein and calcium,
100g sesame seeds contain 26.4g protein, 12.6mg vitamin B3, 7.8mg iron, 131mg calcium and 10.3mg zinc.
- Sunflower
An annual plant belonging to the daisy family, it probably originated
in North America or Mexico. North American Indians cultivated
sunflowers as long as 2,000 years ago. The oil extracted from its seeds
is used in margarine, varnishes and soaps but the seeds can be eaten
whole, raw or cooked. They can be added to breads and cakes or
sprinkled over salad or breakfast cereals.
A good source of potassium and phosphorous,
100g sunflower seeds also contain 24g protein and 7.1mg iron and 120mg calcium.

ONIONSGo back to the food list
Benefits of Onions
The same substances that give onions their pungency are believed to
help fight cancer. A recent study from the National Cancer Institute
found that individuals who ate the most allium vegetables (onions,
scallions, garlic, chives and leeks) had a nearly 50 percent lower
cancer risk than those who ate the least. Some laboratory studies have
shown that the natural substances in these vegetables have anti-tumor
effects. Other studies link the veggies with a lower risk of cancer of
the colon, stomach, prostate, esophagus, breast and endometrium (lining
of the uterus).
What Makes Them So Good for You?
Of
all the healthy compounds contained in onions, two stand out: sulfur
and quercetin - both antioxidants. They each have been shown to help
neutralize the free radicals in the body, and protect the membranes of
the body's cells from damage. Quercetin is also found in red wine and
tea, but in much lower quantities. Interestingly, white onions contain
very little quercetin, so it's better to stick with the yellow and red
varieties. Most health professionals recommend eating raw onions for
maximum benefit, but cooking makes them more versatile and doesn't
significantly reduce their potency. In fact, unlike sulfur compounds,
quercetin can withstand the heat of cooking. One researcher, Dr.
Leonard Pike, director of the Vegetable Improvement Center at Texas
A&M University, is working on producing onions with even higher
levels of quercetin.
Onions And Your Heart
As
with garlic, onions help prevent thrombosis and reduce hypertension,
according to the American Heart Association. The juice of one yellow or
white onion a day can raise HDL cholesterol (the good stuff) by 30%
over time, according to Dr. Victor Gurewich of Tufts University. Red
onions don't provide the same effect.
Onions contain a number of sulfides similar to those found in garlic
which may lower blood lipids and blood pressure. In India, communities
that never consumed onions or garlic had blood cholesterol and
triglyceride levels substantially higher, and blood clotting times
shorter, than the communities that ate liberal amounts of garlic and
onions. Onions are a rich source of flavonoids, substances known to
provide protection against cardiovascular disease. Onions are also
natural anti-clotting agents since they possess substances with
fibrinolytic activity and can suppress platelet-clumping. The
anti-clotting effect of onions closely correlates with their sulfur
content.
The World Health Organization (WHO) supports the use of onions
for the treatment of poor appetite and to prevent atherosclerosis. In
addition, onion extracts are recognized by the W.H.O. for providing relief in
the treatment of coughs and colds, asthma and bronchitis. Onions are
known to decrease bronchial spasms. An onion extract was found to
decrease allergy-induced bronchial constriction in asthma patients.
Onions are a very rich source of fructo-oligosaccharides. These
oligomers stimulate the growth of healthy bifidobacteria and suppress
the growth of potentially harmful bacteria in the colon.
Cancer Prevention
Onion extracts, rich in a variety of sulfides, provide some protection against tumor growth.
In
central Georgia where Vidalia onions are grown, mortality rates from
stomach cancer are about one-half the average level for the United
States.
Studies in Greece have shown a high consumption of
onions, garlic and other allium herbs to be protective against stomach
cancer.
Chinese with the highest intake of onions, garlic, and other
Allium vegetables have a risk of stomach cancer 40 percent less than
those with the lowest intake.
Elderly Dutch men and women with
the highest onion consumption (at least one-half onion/day) had
one-half the level of stomach cancer compared with those consuming no
onions at all.

PEPPERSGo back to the food list
Benefits of Peppers
Peppers are a great food for people seeking a healthy, nutritious diet.
Low in calories, high in Vitamins A and C, peppers are also high in a
very important mineral--potassium. One cup of raw sweet green peppers
contains 22 calories. For comparison a cup of cucumber is 16, cottage
cheese is 223 and whole orange is about 41 calories.
A red sweet or hot pepper contains about ten times more
vitamin A and double the amount of Vitamin C than an immature green
pepper. A 100 gram serving of red hot peppers eaten raw contains 369
milligrams of Vitamin C. The same serving size of sweet raw green
pepper contains 128 milligrams, about one third less.
Whether green or red a pepper contains more Vitamin C than a
whole orange which contains only about 50 milligrams. For potassium
rich foods, an average banana contains 370 milligrams and a cup of
green sweet pepper has 213 mg raw and 149 mg if boiled before being
eaten.

PERSIMMONGo back to the food list
Benefits of Persimmons
A
team of researchers led by Shela Gorinstein from the Hebrew University
of Jerusalem, recently published data on the effects of eating
persimmons on cholesterol metabolism. The experiments were carried out
on rats and therefore extrapolation to humans may be difficult, but it
is evident from Gorinstein's work that eating persimmons alters fat
metabolism in rats. The rat's normal (basal) diet was supplemented at a
level of 7%. The diet also contained added cholesterol. The
persimmon-supplemented diet significantly lessened the rise in blood
plasma lipids. Total cholesterol, LDL cholesterol, triglycerides and
lipid peroxides were all lower in the persimmon group. These blood
plasma lipids normally rise in rats fed a diet containing added
cholesterol. Liver cholesterol levels were also reduced in the rats
eating persimmons.
Gorinstein and her team concluded that persimmon possesses
hypolipidemic and antioxidant properties that are evident when
persimmon is added to the diet of rats fed cholesterol.
Persimmon pulp and peel are both good sources of fiber. This
may explain, in part, the positive effect on cholesterol metabolism.
Persimmons have also been shown to contain antioxidants such as
carotenoids and polyphenols which may also affect fat metabolism. In
addition persimmons are good source of sodium, potassium, magnesium,
manganese and iron. Therefore, for many reasons, adding this colorful
fruit to your diet may be a good idea.
Scientists have found that persimmon plays an important role
in maintaining a healthy heart. Daily intake of one fruit may greatly
reduce the risks of cardiovascular disease such as heart disease and
stroke. This may attributed to the high amount of anti oxidants
contained in the persimmon.
It contains twice as much fiber as that in apples. It is also rich in other elements such as calcium, iron and magnesium.
Foods ‘n herb specialists reckons it: clear heat, lubricate
lungs, relieve diarrhea, treat hypertension, senile asthma and cough
with mucus.
Persimmon tannins have been used as folk medicine for treating
stroke in Japan and as herbal medicine in China since ancient times, and also the lowering of blood pressure.
Other health benefits of the Sharon-fruit as a herbal
medicine, it is effective for recovery from intoxication. Persimmon juice
lowers the density of alcohol in the blood stream and therefore
alleviates hangovers.
Relieving diarrhea – Persimmon tannins calms intestinal
movements. Treating bruises – Persimmon tannins effectively slows
subcutaneous bleeding. When persimmon tannin is absorbed into tissues,
it protects cells, it astringes tissues, and it suppresses the
propagation of bacteria. They are known to protect the body from
influenza by developing resistance against virus infection.
Sharon-fruit is also a good source of Vitamin A. Vitamin A is
required for healthy skin and Mucus membranes, and for night vision.

PINEAPPLE Go back to the food list
Benefits of Pineapple
Pineapples are nutritionally packed members of the bromeliad family.
This delightful tropical fruit is high in the enzyme bromelain and the
antioxidant vitamin C, both of which play a major role in the body's
healing process.
Bromelain is a natural anti-inflammatory that has many health
benefits and encourages healing. According to Dr. Andrew Weil,
bromelain is very effective in treating bruises, sprains and strains by
reducing swelling, tenderness and pain. This powerful anti-inflammatory
effect can also help relieve rheumatoid arthritis symptoms and reduce
postoperative swelling. Additionally, the bromelain contained in fresh
pineapple can relieve indigestion. This enzyme helps break down the
amino acid bonds in proteins, which promotes good digestion.
Pineapples provide an ample supply of vitamin C too, a
commonly known antioxidant that protects the body from free radical
damage and boosts the immune system. Vitamin C helps build and repair
bodily tissue and promotes wound healing. The body uses vitamin C to
help metabolize fats and cholesterol, absorb iron, and synthesize amino
acids and collagen. Collagen is one of the primary building blocks of
skin, cartilage and bones. Vitamin C also decreases the severity of
colds and infections.
Furthermore, due to its high vitamin C content, pineapples are
good for your oral health as well. A study conducted at the State
University of New York at Buffalo found that vitamin C can reduce your
risk of gingivitis and periodontal disease. Besides increasing the
ability of connective tissue to repair itself, vitamin C also increases
the body's ability to fight invading bacteria and other toxins that
contribute to gum disease. Periodontal disease, which destroys gum
tissue and underlying jaw bones, has been linked to heart disease,
stroke and type 2 diabetes.
So if you want a natural way to enhance your body's healing
mechanisms, promote overall good health and tantalize your taste buds,
pineapples are the way to go. Choose the fresh fruit because it has the
most healing properties. Unfortunately, most of the bromelain in canned
pineapple is destroyed due to the heat used in the canning process.

QUINOA Go back to the food list
Benefits of Quinoa
Called
a super-grain; quinoa is highly nutritious and can supply us with all of
the body's requirements: carbohydrates, fats, protein, vitamins,
minerals, and fiber.
Quinoa is gluten free and considered an ideal food for those prone to
food allergies. Common allergens include grains from the grass family
such as corn and wheat. Quinoa, a leafy grain, is not in the grass
family, making it beneficial for people who cannot tolerate common
grains like wheat, corn, rye, barley, and oats.
Nutritional data on quinoa can vary from one variety to another, from
one method of saponin removal to another, and from variations in
growing conditions. Therefore, the data offers a wide spread in its
figures. For instance, its protein content can range from 7.5% to
22.1%. Compared to common wheat at 14%, rye at 12%, and brown rice at
7.5%, quinoa's figures are impressive. In fact, the United Nations'
Food and Agriculture Organization considers quinoa equal to milk in its
quality of protein
Most grains are deficient in the amino acid, lysine. Because quinoa has
an adequate quantity of lysine, it is considered to contain all the
essential amino acids, making it a complete protein.
Quinoa possesses larger quantities of calcium, fat, iron, phosphorus,
and B vitamins than many other grains. One-half cup of dry quinoa
contains 51 mg of calcium, compared to 28 mg in the same quantity of
whole-wheat grains. The protein content is a whopping 11 g for that
one-half cup of quinoa. Potassium is impressively high with 629 mg. as
is zinc with 2.8 mg. Other impressive figures include 42 mcg of folic
acid, 7.9 mg of iron, and 179 mg. magnesium. In the category of fiber
quinoa rates top scores with 5 grams for one-half cup dry grain. One
cup of cooked quinoa has a calcium content equal to that of a quart of
milk.
Quinoa is high in minerals and B vitamins, especially vitamin B6. Two
ounces of cooked quinoa offers 14% of the RDA for B6. Niacin, one of
the B vitamins usually measured in trace quantities, totals 2.49 mg, a
figure considered impressive when it comes to the B vitamins.
An important component of any grain is the germ, that portion of the
grain that is capable of sprouting and becoming a whole plant. The germ
of each quinoa grain is larger than that of any other grain and
encircles the outer surface, explaining its exceptionally high protein
content. "If I had to choose one food to survive on, quinoa would be
the best," said Dr. Duane Johnson, New Crops Agronomist at Colorado
State University.
Some have thought that because quinoa has adapted to growing in such a
difficult environment, one with little cultivation and harsh elements
and has developed such an impressive nutritional profile, bringing the
grain into our own diets may enable us to better adapt to today's
compromised environmental conditions. We may further benefit by
adopting quinoa into our family of familiar grains and bringing more
diversity to our table.

SNOW PEASGo back to the food list
Benefits of Snow Peas
Snow Peas, Sweet Peas, and other green peas are bursting with
nutrients. They provide good to very good amounts of 8 vitamins, 7
minerals, dietary fiber and protein. Green peas' supercharged
nutritional profile can supercharge your health.
Helping Your Bones
Snow Peas and other green peas provide nutrients that are important for
maintaining bone health. They are a very good source of vitamin K1,
which activates osteocalcin, the major non-collagen protein in bone.
Osteocalcin anchors calcium molecules inside of the bone. Therefore,
without enough vitamin K1, osteocalcin levels are inadequate and bone
mineralization is impaired.
Snow Peas and other green peas also serve as a very good source of
folic acid and a good source of vitamin B6. These two nutrients help to
reduce the buildup of a metabolic byproduct called homocysteine, a
dangerous molecule can obstruct collagen cross-linking, resulting in
poor bone matrix and osteoporosis. One study showed that postmenopausal
women who were not considered deficient in folic acid lowered their
homocysteine levels simply by supplementing with folic acid by itself.
Heart
In addition to affecting bone health, homocysteine contributes to
atherosclerosis through its ability to damage the blood vessels,
keeping them in a constant state of injury. Therefore the folic acid
and vitamin B6 in green peas are supportive of cardiovascular health as
well. In fact, folic acid is so important for cardiovascular function
that a major 1995 study concluded that 400 micrograms per day of folic
acid could prevent 28,000 cardiovascular deaths per year in the United
States.
The contributions of green peas to heart health do not stop there. The
vitamin K featured in green peas is instrumental to the body’s healthy
blood clotting ability.
Contributions to Energy and Overall Wellness
Snow Peas and other green peas are one of the important foods to
include in your diet if you oftentimes feel fatigued and sluggish. That
is because they provide nutrients that help support the
energy-producing cells and systems of the body.
Snow Peas and other green peas a very good source of thiamin-vitamin B1
and a good source of vitamin B6, riboflavin-vitamin B2 and
niacin-vitamin B3, all of which are nutrients that are necessary for
carbohydrate, protein and lipid metabolism. Green peas are also a good
source of iron, a mineral necessary for normal blood cell formation and
function, whose deficiency results in anemia, fatigue, decreased immune
function, and learning problems. In addition, green peas are a very
good source of vitamin C, which protects many energy-producing cells
and systems in the body from free radical damage. Body tissues with
particularly high vitamin C requirements include the adrenal glands,
ocular lens, liver, immune system, connective tissues, and fats
circulating in the blood.
Peas Help Prevent Cancer
Snow Peas and other green peas provide nutrients, including vitamin C,
which are instrumental in helping to prevent the development of cancer.
A high intake of vitamin C has been shown to reduce the risks for
virtually all forms of cancer, including leukemia, lymphoma, and lung,
colorectal, and pancreatic cancers as well as sex hormone-related
cancers like breast, prostate, cervix, and ovarian cancers. Vitamin C
is your body’s first and most effective line of antioxidant protection.
Vitamin C protects cell structures like DNA from damage; it helps the
body deal with environmental pollution and toxic chemicals; it enhances
immune function, and it inhibits the formation of cancer-causing
compounds in the body (such as the nitrosamines, chemicals produced
when the body digests processed meats containing nitrates).

SPINACH Go back to the food list
Benefits of Spinach
We grew up with Popeye and the effect spinach had on him. Now science
is bearing out the benefits of this nutrient dense vegetable. Spinach
is one of the healthiest foods we can include in our daily diet.
Spinach provides an excellent source of both Vitamin A and folacin, and a source of fiber, sulfur, potassium and Vitamin C.
Spinach also contains beta-carotene, iron, Vitamin B6, calcium, magnesium and is a source of thiamin.
One cup (180 g) of cooked spinach contains an amazing 147% of the Recommended Daily Intake
That single serving contains 47 calories and 28% of the Recommended Daily Intake of vitamin C;
Benefits of Spinach: The carotenoids and the antioxidant Vitamins of C
and E found in spinach are believed to reduce the risk of cancer, heart
disease, stroke and cataracts.
Potassium and calcium found in spinach can help regulate your blood pressure.
Spinach also provides folic acid, known to reduce the risk of neural of neural tube defect.
Caution: Due to the high levels of oxalic acid found in
spinach, people who have gout, kidney or bladder stones should avoid
this food, as it may irritate these conditions.

SQUASH Go back to the food list
Benefits of Squash
Winter
squash, unlike its summer equivalent, can be harvested very late into
the fall, has a longer storage potential, and still provides an
outstanding variety of conventional nutrients. Winter squash emerged
from our food ranking system as an excellent source of vitamin A (in
the form of beta-carotene), a very good source of vitamin C, potassium,
dietary fiber and manganese. In addition, winter squash emerged as a good source of folate, omega-3 fatty acids, vitamin B1, copper, vitamin
B6, niacin-vitamin B3 and pantothenic acid.
How does this amazing array
of nutrients support our health? One of the most abundant nutrients in
squash, beta-carotene, has been shown to have very powerful antioxidant
and anti-inflammatory properties. Beta-carotene is able to prevent the
oxidation of cholesterol in the body. Since oxidized cholesterol is the
type that builds up in blood vessel walls and contributes to the risk
of heart attack and stroke, getting extra beta-carotene in the diet may
help to prevent the progression of atherosclerosis.
It may also protect
against diabetic heart disease and may be useful for preventing other
complications caused by free-radicals often seen in long-term diabetes.
Additionally, intake of foods such as squash that are rich in
carotenoids may be beneficial to blood sugar regulation. Research has
suggested that physiological levels, as well as dietary intake, of
carotenoids may be inversely associated with insulin resistance and
high blood sugar levels.
Studies have also shown that a good intake of
beta-carotene can help to reduce the risk of colon cancer, possibly by
protecting colon cells from the damaging effects of cancer-causing
chemicals.
Finally, beta-carotene's anti-inflammatory effects may help
to reduce the severity of conditions like asthma, osteoarthritis, and
rheumatoid arthritis, which all involve inflammation.
Other nutrients
found in squash are also useful for a number of different conditions.
The potassium in squash may help to lower blood pressure, and the
vitamin C may be able to reduce the severity of conditions like asthma,
osteoarthritis, and rheumatoid arthritis and also to prevent the
progression of conditions like atherosclerosis and diabetic heart
disease.
Fiber to Fight Heart Disease and Colon Cancer In addition to
its ability to lower high cholesterol levels, which reduces the risk of
heart disease, the fiber found in squash is also able to prevent
cancer-causing chemicals from attacking colon cells. This is one of the
reasons why diets high in fiber-rich foods have been associated with a
reduced risk of colon cancer. The fiber found in vegetables has also
been shown to alleviate the uncomfortable symptoms of diarrhea and
constipation in patients suffering from irritable bowel syndrome.
Anti-Cancer Phytonutrients
Although not as potent as root vegetables like burdock, garlic or
onion, winter squash have been found to have anti-cancer type effects.
Phytonutrient research on squash is still limited, but some lab studies
have shown vegetable juices obtained from squash to be equal to juices
made from leeks, pumpkin, and radish in their ability to prevent cell
mutations (cancer-like changes).
Promote Prostate Health
In research studies, extracts from squash have also been found to help
reduce symptoms of a condition occurring in men called benign prostatic
hypertrophy, or BPH. In this condition, the prostate gland becomes
problematically enlarged, which can cause difficulty with urinary and
sexual function. Particularly in combination with other
phytonutrient-containing foods, squash may be helpful in reducing BPH
symptoms.
Lower Your Risk of Developing Lung Cancer
Consuming
foods rich in beta-cryptoxanthin, an orange-red carotenoid found in
highest amounts in corn, pumpkin, papaya, red bell peppers, tangerines,
oranges and peaches, may significantly lower one's risk of developing
lung cancer. A study published in the September 2003 issue of Cancer
Epidemiology, Biomarkers and Prevention reviewed dietary and lifestyle
data collected from 63,257 adults in Shanghai, China, who were followed
for 8 years, during which time 482 cases of lung cancer were diagnosed.
Those eating the most crytpoxanthin-rich foods showed a 27% reduction
in lung cancer risk. When current smokers were evaluated, those who
were also in the group consuming the most cryptoxanthin-rich foods were
found to have a 37% lower risk of lung cancer compared to smokers who
ate the least of these health-protective foods. (December 3, 2003)
Vitamin A Provides Protection against Emphysema
If
you or someone you love is a smoker, or if you are frequently exposed
to secondhand smoke, then making vitamin A-rich foods, such as winter
squash, part of your healthy way of eating may save your life, suggests
research conducted at Kansas State University. While studying the
relationship between vitamin A, lung inflammation, and emphysema,
Richard Baybutt, associate professor of nutrition at Kansas State, made
a surprising discovery: a common carcinogen in cigarette smoke,
benzo(a)pyrene, induces vitamin A deficiency. Baybutt's earlier
research had shown that rats fed a vitamin A-deficient diet developed
emphysema. His latest animal studies indicate that not only does the
benzo(a)pyrene in cigarette smoke cause vitamin A deficiency, but that
a diet rich in vitamin A can help counter this effect, thus greatly
reducing emphysema. In his initial research, Baybutt took just weaned
male rats and divided them into two groups, one of which was exposed to
cigarette smoke, and the other to air. In the rats exposed to cigarette
smoke, levels of vitamin A dropped significantly in direct correlation
with their development of emphysema. In the second study, both groups
of rats were exposed to cigarette smoke, but one group was given a diet
rich in vitamin A. Among those rats receiving the vitamin A-rich foods,
emphysema was effectively reduced. Baybutt believes vitamin A's
protective effects may help explain why some smokers do not develop
emphysema. "There are a lot of people who live to be 90 years old and
are smokers," he said. "Why? Probably because of their diet…The
implications are that those who start smoking at an early age are more
likely to become vitamin A deficient and develop complications
associated with cancer and emphysema. And if they have a poor diet,
forget it." If you or someone you love smokes, or if your work
necessitates exposure to second hand smoke, protect yourself by making
sure that at least one of the World's Healthiest Foods that are rich in
vitamin A, such as winter squash, is a daily part of your healthy way
of eating. (October, 21, 2004)
A Variety of Health-Promoting Nutrients
Folate to Help Prevent Birth Defects, Heart Attack and Colon Cancer
The
folate found in squash may help to prevent certain birth defects if
taken by women before and during pregnancy. Folate is also needed by
the body to break down a dangerous metabolic byproduct called
homocysteine, which can directly damage blood vessel walls. Since high
levels of homocysteine are associated with an increased risk for heart
attack and stroke, getting plenty of folate in the diet is a good idea.
Folate has also been shown to help protect colon cells from the effects
of cancer-causing chemicals. In fact, diets high in folate-rich foods
are associated with a significantly reduced risk of colon cancer,
especially in people who have a history of alcohol use.

STRAWBERRY Go back to the food list
Benefits of Stawberries
Two
separate studies presented at the 2003 American Dietetic Association
Food and Nutrition Conference and Exhibition reveal that in addition to
being low in fat and calories, strawberries are naturally high in
fiber, vitamin C, folate, potassium and antioxidants, making them a
sweet alternative that advances heart health, reduces the risk of
certain types of cancer, and gives a boost to total body wellness.
Dr. Gene Spiller, Nutrition and Health Research Center,
recently released data showing that when people eat a daily serving of
strawberries (about 8 berries; 45 calories) there are significant
increases in blood folate levels and decreases in systolic blood
pressure, findings that amplify the importance of including
strawberries as part of a heart-healthy diet. Strawberries' propensity
to decrease systolic blood pressure may reduce the risk of heart
disease associated with high blood pressure. Folate reduces levels of
homocysteine, an amino acid which may at high levels block arteries. In
addition, earlier findings showed that strawberries are high in
antioxidants such as ellagic acid and anthocyanins, the red pigment in
strawberries, which is further evidence that strawberries provide an
edge for heart health.
A second study released by Dr. Victor Fulgoni, Nutrition
Impact LLC, further validates these findings and reveals additional
benefits. Like Dr. Spiller's findings, Dr. Fulgoni's research using
large surveys created by the US government showed that compared to
non-eaters, strawberry eaters have higher blood folate levels and lower
levels of homocysteine and tend to have lower blood pressure. In
addition, Dr. Fulgoni's data revealed that strawberry eaters tend to
have higher dietary fiber, folate, potassium and vitamin C intake.
"The body of evidence showing a health benefit of
strawberries continues to grow," said Dr. Fulgoni. "This latest
research demonstrates that people who eat strawberries may be
benefiting from their many nutrients, which may help maintain a healthy
heart." In addition to advancing heart health and reducing risks of
certain types of cancer, strawberries have been shown previously to
enhance memory function and aid in the management of rheumatoid
arthritis.
While long-term health benefits are compelling, for some, the
immediate reward is equally fulfilling. A nutrient dense fruit,
strawberries also have the added benefit of great taste while being
high in fiber. Their versatility and adaptability add interest, lively
color and flavor to either indulgent or healthy recipes. Fresh, frozen
or dried, eaten alone or tossed into cereal, salads or yogurt,
strawberries naturally add a nutritional edge to an ordinary meal or
snack

SWEET POTATO Go back to the food list
Benefits of Sweet Potato
An
endorsement of sweet potatoes as a nutritious food helpful in the
prevention of disease comes from the North Carolina Stroke Association,
American Cancer Society, and the American Heart Association. And
they're not the only ones noticing the attributes of sweet potatoes.
In 1992, the Center for Science in the Public Interest
compared the nutritional value of sweet potatoes to all other
vegetables. Considering fiber content, complex carbohydrates, protein,
vitamins A and C, iron, and calcium, the sweet potato ranked highest in
nutritional value. According to these criteria, sweet potatoes earned
184 points, 100 points over the next on the list, the white potato. The
Center strongly recommends eating more sweet potatoes since a
nutritious diet is one that is high in fiber, provides many nutrients,
is rich in complex carbohydrates, and is low in fat.
More Fiber
The sweet
potato is a good source of dietary fiber, which lowers the risk for
constipation, diverticulosis, colon and rectal cancer, heart disease,
diabetes and obesity. The fiber in sweet potatoes provides a feeling of
fullness and satiety, which helps to control food intake.
More Antioxidants
Antioxidants
play a role in the prevention of heart disease and cancer, and sweet
potatoes supply plenty of the antioxidants, vitamin E and
beta-carotene. These substances are effective in neutralizing free
radicals, which are responsible for damage to cell walls and cell
structures. Vitamin E also protects against heart attack and stroke by
reducing the harmful effects of low-density cholesterol and preventing
blood clots.
Antioxidants are essential for good brain functioning and in
delay in the effects of aging on the brain. A low level of vitamin E
has been linked with memory loss. A Columbia University study showed a
delay of about seven months in the progression of Alzheimer's disease
when subjects consumed high levels of vitamin E. This fat-soluble
vitamin is found mainly in high-fat foods such as oils, nuts, and
avocados. Only the sweet potato provides vitamin E without the fat and
calories.
Sweet potatoes contain 30 mg (50,000 IU) of beta-carotene (vitamin A)
in one cup, which is four times the USRDA. You would have to eat 23
cups of broccoli to consume the same amount of beta-carotene. Health
professionals believe that carotenoids give protection from the
formation of free radicals and are chemo-protective against cancer.
The Finnish study of 10,000 smokers, reviewed in the New England
Journal of Medicine in 1994, tested the effects of taking beta-carotene
supplements to prevent lung cancer. It was based on the earlier finding
that individuals who have higher blood levels of beta-carotene have a
lower incidence of lung cancer. To the researchers' horror, those who
took the supplements actually had a higher rate of lung cancer and the
study was discontinued. Researchers concluded that beta-carotene has a
protective effect only when consumed in food, the original and best
source. The nutrient-packed sweet potato is the richest source of this
protective substance.
Low Glycemic Index
Different
foods have different effects on blood glucose. The glycemic index is a
measure of how quickly glucose is absorbed after a person eats, how
high glucose rises, and how quickly it returns to normal. A low
glycemic index is desirable and is characterized by slow absorption, a
modest rise in blood glucose, and a smooth return to normal. Fast
absorption, a surge in blood glucose, and an overreaction that plunges
glucose below normal are undesirable, and are the result of eating foods
with a high glycemic index. This distinction is especially important
for people with diabetes, whose good health is dependent upon stable
blood glucose levels. As a result, getting enough carbohydrates without
causing glucose spikes can prove challenging. For example, white
potatoes, corn, rice, and white bread all have a high glycemic index
and can cause a spike and an ultimate drop in blood sugar. Diabetics
and others wanting to avoid glucose highs and lows can turn to sweet
potatoes, which have a low glycemic index.
Excellent Source of Potassium
Potassium
plays a major role in maintaining fluid and electrolyte balance and
cell integrity. Controlling potassium distribution is a high priority
for the body because it affects many aspects of homeostasis, including
a steady heartbeat. Fresh fruits and vegetables are the best sources of
potassium, and sweet potatoes are among the top three richest sources,
along with bananas and white potatoes.
Dr. Robert Cordell, emeritus professor of cardiothoracic
surgery at Wake Forest University School of Medicine, highly recommends
sweet potatoes. "Sweet potatoes, a readily available and wonderfully
tasteful root vegetable in the southeastern United States, are
frequently overlooked regarding their health value. Most remain unaware
of the significant health benefits of this low-fat, high fiber
vegetable that is such a rich source of vitamins A and E. Sweet
potatoes, therefore, contain significant deterrents to heart disease
and stroke, both of which tend to be higher in our part of the country.
In addition, reports have suggested anti-cancer effects. With these
facts in mind, all of us should make sweet potatoes a more frequent
part of our regular diet."

TOMATOES Go back to the food list
Benefits of Tomatoes
Tomatoes are loved for their fresh
taste and the versatile role they play in cooking. But research
indicates there may be another reason to love them — they're loaded
with lycopene (LY-ko-pene). Lycopene is a plant chemical
(phytochemical) that gives tomatoes their red color. It also appears to
offer potential health benefits. Tomatoes contain many nutrients, among
them vitamins C and B complex and the minerals iron and potassium. Also
in the mix are carotenoids (kuh-ROT-uh-noids). These include lycopene
and beta-carotene, which are converted into vitamin A by your body.
Lycopene gets high marks from
researchers for its apparently potent antioxidant properties.
Antioxidants are thought to neutralize harmful substances in the body
called free radicals. These molecules, which result from normal cell
metabolism as well as other causes, may increase your risk of cancer
and cardiovascular disease.
Fresh tomatoes are loaded with
lycopene, but cooking tomatoes makes lycopene easier for your body to
use. For instance, your body will absorb five times more lycopene
through tomato sauce than through an equivalent amount of fresh
tomatoes. Evidently, heat breaks down tomato cell walls to free
lycopene that otherwise would pass through your digestive system.

WHOLE GRAINS Go back to the food list
Benefits of Whole Grains
Whole grains can claim a wide
array of health benefits that many foods cannot. Not only do whole
grains contain fiber and traditional nutrients such as B vitamins,
vitamin E, magnesium and iron, but also numerous disease fighting
phytochemicals and antioxidants. More and more, consumers know that
fruits and vegetables contain these disease fighting agents, but what
they do not know is that whole grains contain these important chemicals
much less that they often contain more than most common fruit and
vegetables. Further, some of the antioxidants in grains are not found
in fruits and vegetables.
Studies have shown that people who eat whole grains have lower total
cholesterol. Various large epidemiological studies on a variety of
different populations note that people who eat three daily servings of
whole grains have been shown to reduce their risk of heart disease by
25-36%, stroke by 37%, Type II diabetes by 21-27%, digestive system
cancers by 21-43%, and hormone- related cancers by 10-40%. Furthermore,
in intervention studies where whole grains became a regular part of the
diet, people showed improved blood glucose levels and insulin
sensitivity.
The data have convinced The American Heart Association, the Dietary
Guidelines for Americans, and Healthy People 2010 to all recommend
three daily servings of whole grains. Yet the average American eats
less than one daily serving of whole grains, and over 30% of Americans
never eat whole grains.
