Grain Fiber-vs-Fruit Fiber

Both fruit and grain sources contain dietary fiber. Dietary fiber passes through your digestive system without breaking down, which helps to create bulk in your colon. This substance is needed for regular digestion and to prevent constipation. In addition, other health benefits result from consuming sufficient dietary fiber.

Longer Life

A diet high in dietary fiber can help to reduce cholesterol and aid in weight loss. The dietary fiber found in whole grains reduces the risk of dying at an early age from a range of causes, according to CNN Health. Dietary fiber from grains reduces the risk of dying from heart disease, heart attack, pneumonia and chronic bronchitis. It also reduces the risk of dying from infectious diseases. The link responsible for lowering these risks is not known, although the antioxidants may play a role.

Lowering Cholesterol
Both fruit fiber and grain fiber are shown to lower blood cholesterol levels. Eating a high-fiber diet that is low in saturated fat, cholesterol and trans fat will help to lower high cholesterol. According to the American Heart Association, soluble fiber sources such as oatmeal, oat bran, beans, peas, rice, bran, barley, citrus fruit and apple pulp lower cholesterol.

Blood Sugar Balance

Eating balanced, regular meals keeps blood sugar levels balanced. Blood sugar that rises and drops abnormally, over time, may lead to Type 2 diabetes and weight gain. A diet high in dietary fiber -- particularly soluble fiber -- can slow the absorption of sugar, which will improve blood sugar in diabetics. Soluble fiber sources are mainly fruits, but whole grains -- such as oats and barley -- are also sources. Grain sources of insoluble fiber, such as wheat bran and whole-wheat flour, can also help improve blood sugar and reduce the risk of developing Type-2 diabetes.

Weight Management

People who find it hard to lose weight may want to consider increasing their intake of dietary fiber. A diet high in fiber can help with weight loss. Fiber food sources, both fruit and grain, require more chewing time and work to make you fuller for a longer period of time.
