Food - Fiber Facts: Soluble Fiber And Heart Disease
What Is Fiber?
Fiber is a substance found only in plants, such as fruits, vegetables, and grains. The part of the plant fiber that you eat is called dietary fiber and is an important part of a healthy diet. Dietary fiber is made up of two main types--insoluble and soluble.
What Is The Difference Between Insoluble And Soluble Fiber?
Soluble fiber forms a gel when mixed with liquid, while insoluble fiber does not. Insoluble fiber passes through your digestive tract largely intact. Both types of fiber are important in the diet and provide benefits to the digestive system by helping to maintain regularity. Soluble fiber has some additional benefits to heart health.
What Are Some Good Sources Of Soluble Fiber?
Soluble fiber is found in oats, peas, beans, certain fruits, and psyllium (pronounced sil'e-um). Psyllium is a grain that is found in some cereal products, in certain dietary supplements, and in certain bulk fiber laxatives. Read labels carefully to check for the addition of psyllium.
What Are The Benefits Of Soluble Fiber?
In additional to the digestive system benefits mentioned above, soluble fiber has been scientifically proven to reduce blood cholesterol levels, which may help reduce your risk of heart disease. In fact, the Food and Drug Administration recently authorized food companies to use a health claim for soluble fiber from both psyllium and oats. For example, the new claim for psyllium states, "Soluble fiber from foods with psyllium husk, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease."
