Quizplus · Accepted Answer

Insoluble fiber, such as cellulose, adds bulk to the stool and helps prevent constipation. A is incorrect because insoluble fiber does not form a gel when mixed with water, but rather passes through the digestive system mostly intact. B is incorrect because insoluble fiber is not directly linked to reducing heart disease; however, a diet high in fiber overall, including both soluble and insoluble fiber, may decrease the risk of heart disease. C is incorrect because cellulose is an example of insoluble fiber, not soluble fiber.
