Soy Continued

Soy is sometimes called a "super food" because cultures with high soy content in their diets tend to be healthier. Reviewing the literature on this, there is little effect on bone health, cancer, and kidney disease. While cultures that have high intake of soy based foods have less reproductive cancers, they have much higher incidents of thyroid and digestive cancers.

The Swiss did a study on 1992 which estimated that 100 grams of soy is equivalent to the estrogenic equivalent of the birth control pill. So while this may protect the reproductive track, it may increase cancer formation in the thyroid and digestive tract. Another thought here, if you have an infant who is allergic to milk and you put them on soy based formula what is the estrogenic effect on them?? I don't know, but I would certainly want to look at alternatives.
