High-fiber diet linked to lower risk of death and chronic diseases
(CNN) -- People who eat diets that are high in fiber have lower risk of death and chronic diseases such as stroke or cancer compared with people with low fiber intake, a new analysis found. Dietary fiber includes plant-based carbohydrates such as whole-grain cereal, seeds and some legumes. Fiber's health benefits have been recorded "by over 100 years of research," Andrew Reynolds, a researcher at the University of Otago in New Zealand, wrote in an email. He is co-author of the new meta-analysis of existing research, which was published Thursday in the journal The Lancet.
