Fiber benefits health in many ways. For diabetics, fiber has been shown to delay carbohydrate absorption after meals, thereby reducing the speed at which glucose enters the bloodstream. There is a possibility that fiber may reduce the requirement for the amount of insulin or oral medication used, and that it may improve the efficiency of the insulin naturally secreted by the body. Diets high in fiber promote weight loss by giving a feeling of fullness. A certain type of fiber, soluble fiber, absorbs cholesterol in the gut, thereby reducing blood levels of cholesterol and lowering risk for heart disease. Insoluble fiber has been linked to reduced rates of colon and breast cancers. Good sources of fiber include fresh fruits and vegetables, beans and lentils, and whole grain breads, cereals, and crackers.
Note: any increase in dietary fiber must also be accompanied by an increase in water or other fluids.
