Celiac Disease (CD) or Gluten Sensitive Enteropathy (GSE) is a life‐long disorder. It is characterized by inflammation in the small intestine of genetically predisposed individuals caused by inappropriate immune response to gluten, a protein enriched in some of our common grains (wheat, rye and barley). The toxicity of gluten is manifested by the autoimmune action of T‐lymphocytes on mucosal cells in the small intestine, disrupting its vital function of absorbing nutrients from food.
