<<Disclaimer: Verify this information before applying it to your situation.>> My son has experienced improvement since going GF (and dairy free except for Lactaid milk) about three months ago. He still has bouts with diarrhea, though, and it is really difficult to pinpoint what the cause of the problem is every time. Many times I chalk it up to too much sugar or maybe something that was too fiberous. I am very strict about removing all gluten and cook mainly whole foods. Today the diarrhea is really bad. The only things I can think of are that he had just a very few peas in a dish I made. I used the soft, canned peas at that. The other thing is, could he possibly be casein intolerant? He has been drinking Lactaid but I have been trying to change him to a soy milk, so I have been mixing them. He refuses to drink any kind or straight soy milk. (I have been using Westsoy.) Could the soy milk be causing the problem? For those of you who are casein intolerant, does this type of intolerance cause diarrhea? Any help will be welcomed. Much thanks, Melinda
