What Is Fiber

If you've recently begun eating healthier, you may be asking, "what is fiber?" Dietary fiber is indeed an important part of one's diet. Follow along to learn about what dietary fiber does in order to learn more about his important carbohydrate.

Dietary fiber is the nondigestible part of plant material. It is a complex carbohydrate that serves a number of important functions in the body. There are a number of ways to distinguish fiber, such as soluble (fermented in colon into gases/physiologically active byproducts) and insoluble (metabolically inert, absorbs water as it moves through the digestive system) fiber.

Benefits of fiber. Fiber reduces the glycemic effect of meals and contributes to the health of the colon. It can help lower cholesterol and triglycerides. Additionally, dietary fiber can help to prevent ulcers, heart disease, diabetes and cancer.  Fiber has been demonstrated to help prevent these health conditions, in conjunction with other nutrients and steps.

Sources of fiber. Sources of soluble fiber include berries, apples, oats, plums, beans, and fiber supplements. You can find insoluble fiber in the bran of grains (wheat bran, nuts, and seeds) and vegetables.

Daily amount of fiber. According to most sources, anywhere from twenty to 35 grams a day of dietary fiber is optimal for healthy adults. You can check with your doctor if you have any special dietary fiber needs. However, many adults only obtain a daily intake of twelve to eighteen grams (the average American). The British Nutrition Foundation recommends a minimum fiber intake of eighteen grams a day for healthy adults.
