My DD is not eating dairy, gluten, eggs, and peanuts. This means we have been incorporating soy yogurt, edamame, and various other foods with soy as one of the ingredients (all organic, non-GMO of course). I have heard from a few people that is not a good idea to eat too much soy, if any at all, due to the estrogenic properties, but I have yet to get a straight answer as to a "safe amount" or if there isn't a safe amount, or if we shouldn't eat it at all. Do you limit soy?
Mama to a sweet little redheaded girl, born 11/09; and my HBAC baby, little brother, born 7/12.
I do limit soy. We don't do a lot of processed foods but the ones we do usually have it in some way in it.
Honestly, there are so many other subs that it isn't hard to convert. Coconut milk, yogurt, cheese even. Hemp milk. Rice milk. As long as your DD has a varied diet with the limitations she's got, she'll be fine.
I don't think you'll ever get a straight answer because I don't think there is one.
