In the ordinary metabolic sense of the term, fiber is not a nutrient at all. In a crude and purely physical way, fiber acts as a vital nutrient because it's a substance -- found in food -- that your body needs for one of its most vital functions: To eliminate some of the waste products of ordinary metabolism. Fiber lowers cholesterol and blood sugar levels and helps move waste through the intestines.

Diets rich in plant fiber are related to a reduction of heart disease, colon cancer and diabetes. Most scientists and nutritionists have accepted that the body needs between 20 and 30 grams of fiber per day for optimal elimination of waste. Many people routinely get much less fiber than this. Animal foods have no natural fiber. Highly refined plant foods often have had much of their natural fiber removed.

Getting more fiber is linked to less severe strokes, according to the findings of a Boston study of 50 men and women. Intakes of both total fiber and insoluble fiber were inversely linked to stroke severity. The average fiber intake in the study wasn't even high, only 10 grams a day, which is less than half the Daily Value of 25 grams a day.

Where you get fiber: Fruits, vegetables and whole grains. Fruits and vegetables, except for the very starchy ones like potatoes and rice, generally have the most fiber with the fewest calories. There are also fiber supplements available that have almost no calories at all.

Suggestion: If you're upping your fiber intake, do it slowly to avoid stomach upset. Also, drink lots of water.
