Dietary Fiber:

Dietary fiber, also called roughage, is the part of plants that the body is not capable of digesting or absorbing. There are two basic types of fiber: soluble and insoluble. Soluble fiber dissolves in water to form a gel consistency and includes substances like gums, pectin, psyllium, and beta-glucans. Insoluble fiber does not dissolve in water and promotes the movement of substance through the digestive system by increasing the bulk of the stool, and includes substances like lignin and cellulose.

Answer and Explanation: 1

The following food tends to help lower cholesterol levels D) oat bran

Oat bran is the outer casing of the oat groats and contains a soluble fiber called beta-glucan.

Soluble fiber dissolves in water (like in the intestinal tract) to form a gel consistency, which can help to reduce low-density lipoprotein (LDL) cholesterol and glucose levels by reducing the amount of cholesterol absorbed in to the blood stream.

Beta-glucans are thought to help reduce the amount of cholesterol in the blood because they help remove cholesterol-rich bile which is present to aid in the digestion of lipids (fats).
