Soy Affects Estrogen Levels

by Anonymous

Soy has been shown to affect the thyroid and estrogen levels. Fermented soy (e.g. tempeh, miso) is the only soy that should be ingested in any significant amounts (and this should be moderate.) Beware of the huge soy industry and their propaganda and esp GMO soy. Do your own homework. Check out research by Dr. Mary Enig and Sally Fallon (she may not have the whole picture,but definitely has parts!)

Connection between low thyroid, soy and weight gain

by Savvy Vegetarian

I've heard about this enough from various women, and read enough about it to believe there's some reality to it: soy isn't good for women with low thyroid, it makes them feel sluggish, and gain weight. Plus, I don't think that relying on one food -soy- for most of your protein is a good idea for anybody regardless of the as yet unresolved soy issues. Since that's the case, it makes sense to be cautious about soy.

IMO, for optimum nutrition, vegetarians and vegans need a wide variety of fresh whole foods, including beans, whole grains, nuts & seeds, veggies & fruits. If they have that, they don't need soy. I've heard from way too many vegetarians who believe that if they don't eat lots of soy products at every meal as a complete protein substitute for animal foods, they'll surely die of malnutrition. It all comes back to the many misconceptions about protein in our culture.
