This is really a nutrition question, not allergy.
I'm thinking we're going to try a gluten-free diet for my son who has asthma and some other symptoms. I'm been doing a little research on gluten-free cooking and it seems like everything is focused on replacing the grains rather than just eliminating them. But I think about it and I'm usually happy with just some meat and vegetables at a meal - the bread or rice or whatever is just filler. So do we really NEED grains in our diet from a nutritional standpoint?
