Dietary fiber intake and total mortality: a meta-analysis of prospective cohort studies.

Increased consumption of dietary fiber, especially fiber from vegetables and cereals, may significantly cut down total mortality risk.

This study evaluated the association between dietary fiber intake and total mortality risk. Researchers conducted a meticulous meta-analysis on data extracted from seven prospective cohort studies.

The team of researchers observed that high consumption of diets loaded with cereal and vegetable fiber reduced the likelihood of deaths from chronic diseases and other causes. In contrast, generous intake of fruit fiber was found to have little or no effect on all-cause mortality risk. The results of this meta-analysis reveal that frequent consumers of diets that contain high amounts of fiber, particularly cereal and vegetable fiber, are less likely to die from chronic diseases.
