Many people who have problems with the digestive process can end up craving certain foods. When the digestive system fails to convert food proteins into amino acids, symptoms and cravings occur. Improperly digested food particles are left out of the blood stream and can cause not only cravings, but addiction. This may be a problem for some people at the beginning of a diet, when certain allergens are removed from their food intake.
