High Fiber Foods
The short list: beans, lentils, artichoke, berries, avocado, whole-wheat pasta, chia. The table below uses USDA FoodData Central portions, the same data behind the Dietary Guidelines fiber food-sources table. High fiber on a US label means 5.6g or more per serving, which is 20% of the 28g Daily Value.
Ranked by fiber per portion
Portions are the USDA standard amounts, not a serving recommendation. A cup of lima beans is a lot of beans. Half a cup of navy beans at 9.6g is the more realistic building block. Search or filter by category, then log the ones you actually eat.

High fiber means 20% or more of the FDA Daily Value per portion (5.6g or more). Good source is the rest of this list, which still starts at the Dietary Guidelines cutoff of 2.8g per portion.
How to use this without overdoing it
Most adults start around 16g to 17g a day. Jumping to 38g from beans alone is how people decide fiber does not agree with them. Add one high-fiber food at a time, drink water, and give your gut a few days before adding the next. The Lancet evidence for 25g to 29g a day is from dietary patterns over years, not a single heroic lunch.
Common questions
What food has the most fiber?
Among ordinary kitchen foods, cooked beans and peas sit at the top. A cup of lima beans has about 13g. Half a cup of navy beans has 9.6g. Artichoke, raspberries, split peas and lentils are the next rung. Isolated fiber powders can show higher numbers per spoon, but the Dietary Guidelines target fiber from food.
What counts as a high fiber food?
On a US food label, "high fiber" means 20% or more of the Daily Value per serving, which is 5.6g or more when the Daily Value is 28g. "Good source" is 10% to 19% (2.8g to 5.5g). The list on this page uses those same USDA portions.
How can I get 25 to 38 grams of fiber a day?
Two bean portions, a cup of berries or a pear, and a whole-grain side will usually cover most of the target. A typical day that hits 30g without powders: oatmeal at breakfast, lentils or black beans at lunch, raspberries as a snack, broccoli or artichoke at dinner, and a tablespoon of chia or flax somewhere in between.
Should I add fiber supplements?
Food first. The health outcomes in the Lancet carbohydrate-quality review are from dietary fiber in plants, not isolated powders. Psyllium and similar supplements can help constipation for some people, but they do not replace the rest of what beans, fruit and whole grains bring. If a clinician recommended a supplement, that sits on top of food, not instead of it.
