 Soyabean/Edamame is cheap to grow
and yet is rich in calories, proteins and fats
In 1999, the U.S. Food and Drug Administration
made it official: Food manufacturers have the green light to trumpet the cholesterol-lowering benefits of
soy on their labels. Eating 25 grams of soy protein a day -- the equivalent of a cup of soy milk
with breakfast and an energy bar laced with soybeans for a snack -- has been
shown to lower total cholesterol an average of 9%, according to the U.S.
Department of Agriculture. That much soy is also enough to reduce the most
dangerous form of cholesterol, low-density lipoprotein, or LDL, by an impressive
13%. Daily servings of soy may also help strengthen bone, ward off the side effects of
menopause in women, and lower the odds of prostate cancer in men -- though these benefits are
less certain than the good news about heart disease, according to Greg Burke, a leading soy
researcher at Wake Forest University. Thanks to the FDA's seal of approval, more and more foods
containing soy are appearing on grocery store shelves. Still the best bet, says Burke, is eating
whole soy foods like edamame (boiled fresh or frozen soybeans), tofu, or soy milk.Composition
Soyabean contains 19.5% fat, 21% carbohydrates and provides 432 kcal per
100 gms
Proteins Soyabean contains 43% protein, which is higher than in any
other protein rich foods, including meat and fish which contains 20%. The
proteins of soyabean yields all essential amino acids in adequate amounts,
except methionine and cystine. Soyabean is rich in lysine and can be used
to supplement a staple rice diet.
Soyabean Milk
The starch content of soya milk is quite negligible, and saccharides are
low, making it suitable for diabetic patients.
