The USDA has released updated dietary guidelines recommending Americans consume 50 grams of fiber daily, nearly double the previous recommendation of 28 grams, citing overwhelming evidence for disease prevention.

Why More Fiber

A comprehensive review of 180 studies found that higher fiber intake reduces risk of heart disease by 30%, Type 2 diabetes by 25%, and colorectal cancer by 20%. Most Americans currently consume just 15 grams daily.

Best Sources

Nutritionists recommend whole grains, legumes, fruits, and vegetables rather than supplements. A single cup of lentils provides 16 grams of fiber.
