Fiber plays an important role in a healthy diet by promoting healthy passage of stool and by helping to prevent many digestive and chronic diseases. Select all that apply.

a. Humans do not produce enzymes in the small intestine that can break down fiber Bacteria in the large intestine are able to ferment all forms of previously undigested insoluble fiber
b. Fiber can increase the absorption of cholesterol into the bloodstream, potentially resulting in increased heart disease risk

d. Fiber can help reduce the risk of diverticulosis, obesity, and certain cancers.

Explanation:

• Fiber is a type of carbohydrate which can not be broken into simple sugars by human digestive system because suitable enzymes for its breakdown are not produced in humans.
• Instead, fiber specially insoluble fiber plays an important role in making the bulk of stool for its easy passage and avoiding constipation.
