Dietary fiber: adequate intake and effects on metabolism health

The positive effects of dietary fiber are related, in part, to the fact that a portion of the fermentation of components takes place in the large intestine, which has an impact on the speed of digestion, pH of the colon, and production of by-products with important physiological functions. Individuals with high fiber intake seem to have lower risk of developing coronary artery disease, hypertension, obesity, diabetes, and colon cancer. The increase in fiber intake reduces serum cholesterol, improves blood glucose in patients with diabetes, reduces body weight, and is associated with lower serum ultrasensitive C-reactive protein. Increased fiber intake and intake of more fiber than the currently recommended level (14 g/1,000 kcal) may provide greater health benefits, including reducing low-grade inflammation.
