150 foods in the USDA FoodData Central database carry measurable Dietary Fiber content. The FDA Daily Value for Dietary Fiber is 28g, which means every food on this list can be scaled back to a percent-DV figure for an adult on a 2,000-calorie diet. The current number-one food clocks in at 108g per serving, 385% of the daily reference value in a single portion. That kind of concentration is rare and tells you which foods act as genuine Dietary Fiber drivers rather than marginal contributors.

Foods span multiple USDA food groups, giving you category-level options for meeting your daily target. Category breakdowns matter because they reveal whether the nutrient is concentrated in one food family, where a single good choice moves the needle, or dispersed, where daily intake depends on variety across meals.

Supports digestive health, helps maintain blood sugar levels, and promotes satiety. All values in this ranking come from USDA laboratory analysis and manufacturer-reported label data, normalized to per-serving so you can compare foods on equal footing.

For interpretation context, the nutrition guides explain how to balance % DV across a full day and why nutrient density, not just absolute amount, drives healthier food choices.
