​Adequate intake of foods high in dietary fiber may help guard against the development of inflammatory bowel diseases, such as ulcerative colitis and Crohn's disease.

This study investigated the association between high dietary intake of foods rich in fiber and the likelihood of developing inflammatory bowel diseases, such as ulcerative colitis and Crohn's disease. A team of Chinese researchers performed a meta-analysis on data extracted from 8 eligible studies.

The researchers discovered that frequent consumers of diets rich in high-fiber foods were less prone to develop Crohn's disease and ulcerative colitis compared to individuals who rarely consumed or completely avoided foods with high fiber content. The consumption of an extra 10 grams of fiber per day was found to decrease Crohn's disease risk by 13% in this study. The findings of this meta-analysis suggest that regular consumption of fiber-rich foods may help reduce the incidence of inflammatory bowel diseases, such as ulcerative colitis and Crohn's disease, in the general population.
