Physiology of Intestinal Absorption and Secretion
The gastrointestinal tract includes your mouth, stomach, small intestines and large intestines. Approximately 92 to 97 percent of the nutrients consumed, which includes carbohydrates, protein, fat, fluid, vitamins and minerals, are absorbed through the GI tract, says Sylvia Escott-Stump, a registered dietitian and published author. Digestion and absorption of foods begins in your mouth and extends down through your colon, and each area is responsible for breaking down foods with a variety of enzymes and absorbing nutrients.
