Enteral therapy defined as providing medical food to persons with physical or mechanical reasons oral foods cannot be ingested and digested.

Normal digestion occurs when food is broken down in the stomach and bowel, then absorbed in the bowel. These absorbed products are carried by the blood to all parts of the body.

Enteral feeding is when the specialized medical food containing the same carbohydrates (sugar), protein, fat, vitamins and minerals in foods are delivered directly to the stomach or small intestine for absorption into the blood stream.
