INTRODUCTION Small intestine is that part of gastrointestinal tract which connects the stomach with thelarge intestine. Comprising of three different region, duodenum, jejunum and ileum, the smallintestine is involved in three different functions namely, digestion, absorption andimmunological. Most of the nutrients from the ingested food are absorbed in the small intestine(Santaolalla & Abreu, 2012). The surface area of small intestine, formed by presence of villi andthe microvilli is an important factor for normal nutrient absorption. Gluten intolerance damagesinternal lining of small intestine which disrupts nutrient absorption. MECHANISMS USED FOR NUTRIENT ABSORPTION The digested food passes through the small intestine and is absorbed in the blood vesselsthrough active transport or diffusion. There is a lining of columnar epithelial tissue in the smallintestine. This lining, called mucosa, has a covering of folds called plicae circulares whichcontain villi and micro villi (Wierdsma & et.al., 2013). The plicae circulares, villi and microvilli,together increase the surface area for the absorption of nutrients. This serves the purpose oflimiting the loss of nutrients to the intestinal fauna. The villi contains a network of capillariesand fine lymphatic vessels. The nutrients are transported from the intestine to the capillaries bythe epithelial cells of the villi. These absorbed nutrients are then transported to different organsof the body via blood vessels (Caruso & et.al, 2013). GLUTEN INTOLERANCE AND ITS EFFECT ON NUTRIENT ABSORPTION Gluten is a protein found in wheat, rye and barley. Gluten intolerance refers to acondition, which is characterized by reaction of a person on ingestion of gluten. When a person1
