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.

Ensuring that your vegetarian diet contains enough iron & protein (& vitamin B12)

Someone asked me about getting enough iron and protein in a vegetarian diet with milk, but no eggs. It's difficult to get enough iron or protein without meat, fish, or eggs, so I’m not surprised that the questioner’s son has low hemoglobin. My answer: try to eat beans at most meals (together with fruit or veggies for vitamin C to help you absorb the iron). You’ll need to eat all sorts of beans, like lentils (dal), kidney beans (chili), garbanzos (hummus), etc. to get some variety, but in particular try to eat soybeans (edamame) or tofu. Here’s a quick recipe that kids like:

Crispy Tofu Tenders
Cut open tofu package with a knife and drain out water. Cut tofu into slices about 3/4 inch thick, and drain on several layers of paper towel. Cover with additional paper towels, and press lightly to dry. Leave to dry for a couple of minutes. Cut slices into cubes. Heat about one tablespoon of olive oil in a nonstick pan, or two tablespoons in an iron frying pan. Fry tofu until it is crispy and brown on at least two sides. Serve immediately with soy sauce for dipping. An alternative dipping sauce is mayonnaise with a little catsup mixed in.

P.S. It’s very unlikely that you’re getting enough vitamin B12 if dairy products are your only animal foods. Take a multivitamin&mineral with B12.
