I read that it is the casein protein in milk that is the problem, and that's going to be in cheese aswell. When they make cheese, they separate the casein and whey protein, and that might be why a lot of people are okay with whey protein. I've also read, however, that it is just milk some people have problems with. Ricotta cheese is, I think, mostly whey protein. I don't know about the different animal milks.

Autistic children have benefited from a dairy and gluten free diet, and that might be a tie in with the mercury. I heard the other day that some expert has found that autistic children have a measles virus in their stomach and it's that causing the autism, not mercury. Anyone know more?
