Absolutely your allergies can cause numerous problems, especially the gas,
bloating, and heartburn. My daughter has multiple
food allergies (milk, soy, wheat, fish, shellfish, apples) and we have to stick to an extremely controlled diet with her. I am gluten intolerant also, and I had the same type of symptoms from eating anything with gluten in it. We also have intolerances to some food additives such as MSG, sulfites, nitrites.
