Whole Grains and Fiber Linked with Lower Risk of Many Diseases

Whole grains are one of the most popular food sources of fiber, and both whole grains and fiber are important for overall health. In this study, researchers analyzed data from more than 200 studies encompassing 4,635 participants to better understand fiber and whole grains’ relationship with disease prevention. Fiber was linked with a 15-30% lower risk of heart disease, stroke, type 2 diabetes, colorectal cancer, and death, with similar findings for whole grains. The researchers noted a dose-response relationship for both whole grains and fiber, indicating that those who eat the most may confer an even greater benefit.
