Fibers are complex carbohydrates that aid in digestion by stimulating peristalsis (the muscular contractions that move food through the gut) and facilitating the passage of food in the gastrointestinal tract. Fats and lipids are related and are not complex - carbohydrates. Minerals are inorganic substances and do not have this digestive - stimulating function.
