Food intolerance is an adverse food reaction due to a lack food specific digestive enzymes. An enzymes deficiency occur when the body is unable to produce a sufficient quantity of enzymes to properly break down foods eaten. Unlike a life-threatening food allergy, intolerance does not involve the production of antibodies, nor is it mediated by histamine. Adverse food reactions are widespread. For Example, lactose intolerance affects 30-50 million Americans, and as much as 15% of the worldís populations suffers when consuming gluten. Other common intolerable foods include dairy protein (casein), lactose, whey and fibrous beans, vegetables and grains.
