Except for all those Asians who've been consuming it for thousands of years and enjoy some of the highest life expectancies in the world.
Environmental scientists are worried about low levels of estrogenic compounds in water -- giving soy to a baby may be a far worse threat....
Did these do gooder scientists happen to to say what they'd give a baby in place of the dangerous soy milk that meets the baby's need for high quality protein if they're allergic to milk? What nonsense. Soy milk provides more than 10 times as much essential fatty acids as cow’s milk. Cow's milk contains more than nine times as much saturated fat as soy milk. Soy milk is cholesterol-free, while cow’s milk contains 34 mg of cholesterol per cup. Soy milk lowers both total and LDL cholesterol levels, while cow’s milk raises both total and LDL cholesterol levels plus is a great source of high quality protein that infants absolutely must have.
Check out that article I linked for comparisons of relative dosage of soy ... Asian consumption rates tends to be far lower. The question is not about all the other good things in soy milk, but the effects of high loadings estrogenic compounds.
