because neither of my children could tolerate milk-based formula-and through health problems, I had to switch from breast feeding to soy formula. they are 12 and 15 and no thyroid problems. However, they eat a great variety of foods now and can and do eat anything and everything! Perhaps some people have an inborn allergy to soy. i use it every day as one of my sources of protein and milk-no problems. I'm sorry for those that do-I'm glad that rice products are available also! Only good cheese substitute I've found is made from rice!We all have foods we cannot tolerate-maybe for some babies and adults and kids too much is just too much for their systems to handle!!!! This may make parents more aware to seek out the knowledge they need to feed theor infants/children safely!Maryh
