Soybeans are not dangerous

There have been all sorts of rumors about dangerous things in soy, such as estrogen-like compounds that might have feminizing effects or encourage the growth of some breast cancers, or compounds that might be bad for your thyroid gland. Stop worrying!

There is no evidence that the very slight estrogen-like activity in soy has any harmful or even significant consequences. I wonder if this rumor is promoted by the dairy industry– since cow’s milk makes your blood cholesterol go up and soy products make it go down, they need to grasp at some straws.

Just remember that Asian cultures have eaten tofu, made soymilk and enjoyed good health for thousands of years. For you jocks it is a rare vegetarian source of high quality protein. For those of you worried about heart disease it contains healthy polyunsaturated fats, plant sterols and fibers to lower your blood cholesterol.

You probably don’t want to overdo it, just like you don’t want to overdo anything, even things as healthy as drinking water and getting some sun. And I wouldn’t want to subsist on all sorts of products made out of highly processed soy powders- or other kinds of refined or purified products– but there isn’t any reason to shy away from tofu or edamame or a glass of soy milk.

Ignore the rumors- soy is a great food

Because the Japanese traditionally eat soy products and have low rates of breast cancer along with generally good health, we think that soy is probably a good thing. Tofu, edamame, and soymilk have all withstood the test of time.

If you like to engage in ‘nutritionism’, evaluating food on the basis of known nutrients (from Michael Pollan), you might base soy’s benefits on it being rich in protein, iron, calcium, zinc, magnesium potassium, B vitamins, and healthy omega-3 fat.

Why have people heard that soy might not be great? Some people are allergic, some are intolerant, some abused it by eating it 6 times a day, but you could say the same of whole wheat. Don’t become obsessive about any one food.

Next time you order a cappuccino, try it with soymilk. Instead of letting milk’s evil saturated fat clog your arteries, you’ll be lowering your cholesterol with soy’s healthy unsaturated fats and plant sterols. Yeah, I know the taste is an acquired one.
