Other studies indicate such a diet may reduce the risk of onset of non-insulin dependent diabetes in humans. Low GI diets also reduce mean blood glucose concentrations, insulin secretion and serum triglycerides. As low GI foods tend to be less digestible than high GI foods, they should also contribute to the amount of CHO entering the colon. Low GI foods eaten before prolonged exercise may improve endurance, whereas high GI foods lead to faster muscle glycogen replenishment after exercise. Low GI foods include legumes, pearled barley, lightly refined grains such as whole grain pumpernickel or breads made from course flour and pasta.
Most fruits have lower GIs relative to white bread.
