ABSTRACT
All disturbances related to food intake, digestion, absorption and elimination affect the gastrointestinal tract and usually require special diets. Such diets were among the very first ever used in the treatment of diseases. A peptic ulcer is an erosion or open sore in the upper gastrointestinal tract, usually near the pylorus, the opening between the stomach and the small intestine. An ulcer on the stomach side of the pylorus is called a gastric ulcer; one on the duodenal side is called a duodenal ulcer. The basis for the toxicity of gluten in wheat, rye, barley and oat grains is unknown but might be related to the content of amide or bound glutamine and proline. The toxic glutens have a higher percentage of amide nitrogen than the well-tolerated corn and rice. The inflammation in Crohn’s disease usually involves the lower part of the small intestine. In Crohn’s disease, the inflammation appears to penetrating, leading to stricture and to fistula formation.
