Daily fiber intake helps control cholesterol, blood pressure, glucose, insulin and excess body weight. It also helps regulate multiple facets of the digestive system. The recommended amount of dietary fiber per day is 38 grams for men and 25 grams for women. Two fruits and three vegetables servings everyday can help adults get the recommended amount of dietary fiber. A new research suggests that people who get dietary fiber from many sources benefit more than those who limit their intake to a single food or low-fiber diets.
Julie Miller Jones, professor emeritus at Minnesota-based St Catherine University said, "Men typically get around 18 grams and women get around 15 grams. The problem is that when consumers choose fruits or vegetables, it is often low-fiber options such as one piece of lettuce and a thin slice of tomato on a sandwich."
Instead of focusing at only plant-based sources, people should strive for a mix of fiber sources, including fiber that has been added to food in the manufacturing process. Such foods include fiber-fortified bread, cereals, yogurt and pasta. The authors noted, "A combination of naturally occurring and added fiber can increase the chances of achieving the health benefits of a high-fiber diet."
