Answer:
Keep digestive track healthy
prevent buildup of LDL cholesterol in blood stream
Explanation:
Dietary fiber is a type of carbohydrate with high amount of fiber content which makes it insoluble and unable to be digested by the body. The fiber helps in easing of bowel movements which makes the digestive tracts healthier and free from harmful substances. The dietary fiber also attaches itself to LDL cholesterol and prevents its absorption into the bloodstream as it is excreted out as faeces.
