Food rankings
Highest-fiber foods, ranked
Dietary fiber supports digestion, steadier blood sugar, and lasting fullness, yet most adults fall short of the FDA Daily Value of 28 grams. The foods below pack the most fiber into every 100 grams in our USDA-sourced database — a practical shortlist for closing that gap. Legumes, whole grains, seeds, and certain vegetables and fruits tend to lead.
Ranked by grams of dietary fiber per 100 g; Daily Value is 28 g.
