Soy, in its unfermented state (edamame, tofu, soy milk, and anything made from them), is not healthy. Small amounts are perhaps ok, but not daily or often, or large portions. Fermented soy (miso, natto, soy sauce, tempeh, etc.) is more healthy and actually isn't harmful in the way unfermented soy is, and is actually beneficial.

Another concern with soy is that over 90% of US soy is GMO soy. Being GMO, soy is doused with Round-Up pesticide. You are ingesting the glyphosate and other ingredients of Round-Up. This is beyond the fact that genes of another species is inserted into the seed, which may, in itself, prove to be harmful.

These gurus tout that soy is a super food, lowering cholesterol, preventing heart disease, osteoporosis, and certain cancers. Soy that is unfermented contains phytic acid, and large amounts of this can block your consumption of certain minerals. These may include magnesium, iron, iodine, zinc, and copper, which are essential minerals. Soy (unfermented) may weaken the immune system, and can contribute to thyroid disorders. It can contribute to food allergies, digestive intolerances, and kidney stones.

Unfermented soy can mimic the effects of estrogen, a female hormone, since it contains phytoestrogens.

Fermented soy can help your gut bacteria (recolonize helpful bacteria), as is the case with many fermented foods. The phytic acid is neutralized when fermentation takes place.

Seriously, decrease your intake of unfermented soy - and make sure it's not in your baby's formula (which would deliver high doses of soy in a still forming infant). Soy is NOT the health food these gurus would have you believe - use it in moderation, and make sure it's organic.

I've been researching soy for awhile, since my daughter became a vegan and was using more soy products. I encourage her to find other alternatives, or at least, use orgainc, fermented soy products.
