Method
- Values are per 100 g of food, as reported in USDA FoodData Central.
- Source: SR Legacy (April 2018 release) and Foundation Foods (April 2026 release), deduplicated.
- The table lists the top 50 foods, sorted by the ranking value.
This list ranks foods by fiber per 100 g, so the entries near the top are the most concentrated sources of fiber by weight within grains and cereals.
Values are per 100 g of food. A high rank means high fiber density, not that a food is the only or best choice overall.
