I am always leary of food allergy/sensitivity tests. Everyone is going to test positive to a dozen things and then suddenly you are left eating vegetables and water. I am exaggerating but I think there is an industry that preys on finding things wrong with people's health...that really are minor in most cases. Always trying to sell us something. I had a friend that went to an allergist and he came back with 20-30 things he is "allergic" too. I told him....good luck with that!
I am not saying that legit allergies don't exist, but I think they often get blown way out of proportion.
