Well, what we learned is that *some* studies have shown that soy might interfere with reproduction. It is so early to tell long-term, but basically the high levels of plant estrogen in the soy plant can be mistaken by the body as "regular" (human) estrogen. When the body detects high levels, it stops manufacturing enough estrogen for itself. This was all in the very early stages of research when we were thinking about it, but it was enough for us to decide not to do it.
I'm sure you could fimd a ton of people who would disagree with all of the above, but again, to each his own choice.
The goats milk was that bad, huh? Oprah drank it for the first time ever on tv, and she said it wasn't too bad. Maybe it's like soy in that it depends on the brand? My dh will occasionally drink soy, but only 8th Continents, he says the rest are gross. Maybe try another brand??
