Quizplus · Accepted Answer

Insoluble fiber includes plant-based carbohydrates that pass through the digestive system undigested, providing bulk to stool and promoting regular bowel movements. Cellulose is the main type of insoluble fiber found in plant foods such as fruits, vegetables, whole grains, and legumes. Glucose, starch, sucrose, and phospholipids are not insoluble fibers. Glucose and sucrose are simple sugars, starch is a complex carbohydrate that can be either soluble or insoluble depending on how it is cooked, and phospholipids are a type of lipid, or fat.
