Food Allergies

Any food can cause such a reaction in a susceptible individual, but the most common food allergies are those to milk, fish meat, eggs, beans, and nuts. It is interesting to note that the underlying cause for food allergies and sensitivities in some individuals may be increased gut permeability, alterations in gastric acidity, intestinal motility, and other functions of the gastrointestinal tract. Many patients with food allergies are found to have little or no hydrochloric acid output. Increased gut permeability can be caused by vasoactive amines in food, bacteria, non-steroidal anti-inflammatory drugs (NSAIDs), or alcohol.
