Is it true that soy protein is really, really bad?
I really don't see any confusion with its nutritional value. Whenever people engage me in the soy argument, they either point to studies involved isoflavone isolates that are in higher concentrations than products made from whole soy (i.e. some companies sell isoflavone concentrates) or they lead me to studies involving babies who were exclusively fed soy formula (well, doh, I bet if we only fed babies corn they'd develop poorly, too) - there is still not one shred or scrap of evidence that having moderate amounts (5 - 50 grams of soy protein) from whole sources in a nutrition program has any adverse effects, whatsoever.
We all drink soy milk in this family, and have a super clean bill of health - and we've been drinking it for years.
Of course, we are not a "test case" for the masses but it's good enough for me.
The only debate over soy I see tends to get involved with the supplement company wars over whey, soy, etc, and most of the advice for or against comes from either soy companies (for) or companies that promote non-soy products (against). No independent reviews that I can find relate anything negative.
I can find reams of sites with controversy about whole milk, too, to say you shouldn't have that with a cup of oatmeal. Personally, I think if you had nothing but milk you'd develop issues, but a little here or there? Shrug.
