To increase dietary fiber, consumers are turning to non-traditional fiber sources, including dairy foods
Regardless of the dietary delivery vehicle, fiber plays an important role in human health. For starters, non-fermentable fiber, such as wheat bran, is well known for its laxation effect; however, research indicates fibers that are fermentable give benefits that are even greater. Fermentable fiber resists digestion and absorption in the small intestine, with complete or partial fermentation taking place in the large intestine. This action has been strongly associated with reducing the risk of colon cancer. Epidemiological studies have shown that diets low in saturated fat and cholesterol and high in fiber help reduce the risk of certain cancers, diabetes, digestive disorders and heart disease. We now understand that a variety of fibers are an important part of the mix.
