Is Soy and Tofu okaya?

Recently, scientists have been finding some harsh side effects of high soy intake. Excess hormones in the soy (primarily estrogen) can induce male breasts with other female characteristics. At the moment, I would stay away from soy until scientists get more information pertaining to its long term use.

A study was done on babies revealing changed levels in hormones and moodiness.

One might think, well, don't people in Asia eat tons of soy? Actual intake of soy is very minimal compared to the U.S. per person, thus, negative effects were not showing up in the general population.

Here's an excerpt:

Soy is feminizing, and commonly leads to a decrease in the size of the penis, sexual confusion and homosexuality. That's why most of the medical (not socio-spiritual) blame for today's rise in homosexuality must fall upon the rise in soy formula and other soy products. (Most babies are bottle-fed during some part of their infancy, and one-fourth of them are getting soy milk!) Homosexuals often argue that their homosexuality is inborn because "I can't remember a time when I wasn't homosexual." No, homosexuality is always deviant. But now many of them can truthfully say that they can't remember a time when excess estrogen wasn't influencing them.

Here's more:

The soybean has one of the highest phytate levels of any grain or legume that has been studied,16 and the phytates in soy are highly resistant to normal phytate-reducing techniques such as long, slow cooking.17 Only a long period of fermentation will significantly reduce the phytate content of soybeans.

When precipitated soy products like tofu are consumed with meat, the mineral-blocking effects of the phytates are reduced.18 The Japanese traditionally eat a small amount of tofu or miso as part of a mineral-rich fish broth, followed by a serving of meat or fish.

Vegetarians who consume tofu and bean curd as a substitute for meat and dairy products risk severe mineral deficiencies. The results of calcium, magnesium and iron deficiency are well known; those of zinc are less so.

And more:

Daniel Sheehan, Ph.D., director of the Estrogen Knowledge Base Program at FDA's National Center for Toxicological Research, also urges caution in consumption of soy isoflavones. In formal comments submitted to the public record of his own agency while FDA was reviewing the health claim, Sheehan, along with colleague Daniel Doerge, Ph.D., wrote, "While isoflavones may have beneficial effects at some ages or circumstances, this cannot be assumed to be true at all ages. Isoflavones are like other estrogens in that they are two-edged swords, conferring both benefits and risks."

There are benefits too:

Soy Benefits

Soy protein products can be good substitutes for animal products because, unlike some other beans, soy offers a "complete" protein profile. Soybeans contain all the amino acids essential to human nutrition, which must be supplied in the diet because they cannot be synthesized by the human body. Soy protein products can replace animal-based foods--which also have complete proteins but tend to contain more fat, especially saturated fat--without requiring major adjustments elsewhere in the diet.

While foreign cultures, especially Asians, have used soy extensively for centuries, mainstream America has been slow to move dietary soy beyond a niche market status. In the United States, soybean is a huge cash crop, but the product is used largely as livestock feed.
