15 High-Fiber Foods That Do More Than Add Roughage
Most people are still well short on fiber. These foods help close that gap while bringing other useful nutrition with them.

This ranking focuses on foods that meaningfully deliver dietary fiber per 100g, using USDA FoodData Central as the source of truth. It is a concentration ranking, not a full health score, so the most useful way to read it is to look for foods that fit both your nutrient target and your normal portion sizes.
Why it matters
Dietary fiber is the undigestible part of plant foods, and it is crucial for digestive health. Soluble fiber (oats, beans) lowers cholesterol and stabilizes blood sugar. Insoluble fiber (whole grains, vegetables) adds bulk to stool and prevents constipation. Fiber also feeds beneficial gut bacteria, supporting your microbiome.
Daily target
The FDA daily value is 28g, but most Americans get only about 15g. Increasing fiber gradually (with plenty of water) avoids bloating and discomfort. Every 10g increase in daily fiber is associated with a 10% reduction in colorectal cancer risk.
How to use the list
Focus on whole food sources rather than supplements. Beans, lentils, and whole grains are the fiber champions. Adding chia seeds or ground flaxseed to smoothies or yogurt is an easy way to boost intake without changing your meals.
Screening rule
Foods had to clear basic practicality filters before ranking so the list stays useful, not just technically correct.
Best use case
Use this template when you want the single strongest sources of one nutrient and you are willing to compare foods mainly on that axis.
Main caveat
Per-100g leaders are not always everyday staples, which is why calorie density and tradeoffs are called out inside the list.
There is a reason Seeds, chia seeds, dried leads this list: 34g of dietary fiber per 100g is elite territory. That translates to 123% of the daily value, so it can materially move your intake in one serving. The tradeoff is calorie density at 486 kcal per 100g, so this works better as a measured addition than a pile-it-on food. It also brings useful amounts of protein (33% DV) and iron (43% DV), so it is not just a one-stat food.
Worth knowing
Calorie-dense at 486 kcal per 100g, so portion size matters.
Seeds, flaxseed belongs in the top tier of this ranking, with 27g of dietary fiber per 100g. That translates to 98% of the daily value, so it can materially move your intake in one serving. At 534 kcal per 100g, the nutrient density is strong but the portion size still deserves respect. The extra protein (37% DV) and iron (32% DV) help this entry hold up outside of the headline nutrient.
Worth knowing
Calorie-dense at 534 kcal per 100g, so portion size matters.
Seeds, pumpkin and squash seeds, whole, roasted, without salt stays near the top because 18g per 100g is still a very aggressive number for dietary fiber. 66% of the daily value is enough to make this a serious contributor rather than a token source. At 446 kcal per 100g, the nutrient density is strong but the portion size still deserves respect. The extra protein (37% DV) and potassium (20% DV) help this entry hold up outside of the headline nutrient.
Worth knowing
Calorie-dense at 446 kcal per 100g, so portion size matters.
Barley, hulled ranks this highly because it is one of the cleaner ways to get a lot of dietary fiber quickly. That translates to 62% of the daily value, so it can materially move your intake in one serving. The tradeoff is calorie density at 354 kcal per 100g, so this works better as a measured addition than a pile-it-on food. The extra protein (25% DV) and iron (20% DV) help this entry hold up outside of the headline nutrient.
Barley, pearled, raw makes the cut on substance, not hype: 16g per 100g is enough to matter in an actual diet. 56% of the daily value is enough to make this a serious contributor rather than a token source. The tradeoff is calorie density at 352 kcal per 100g, so this works better as a measured addition than a pile-it-on food. It also chips in with some protein (20% DV).
Oat bran, raw is not the flashiest name on the page, but the nutrient density is real at 15g per 100g. That translates to 55% of the daily value, so it can materially move your intake in one serving. It also brings useful amounts of protein (35% DV) and iron (30% DV), so it is not just a one-stat food.
Rye grain holds its spot because 15g of dietary fiber is still comfortably strong. You are looking at 54% of the daily value per 100g, which is why it stands out in a nutrient-specific ranking like this. The extra protein (21% DV) and magnesium (26% DV) help this entry hold up outside of the headline nutrient.
Nuts, almonds, honey roasted, unblanched is not the flashiest name on the page, but the nutrient density is real at 14g per 100g. You are looking at 49% of the daily value per 100g, which is why it stands out in a nutrient-specific ranking like this. At 594 kcal per 100g, the nutrient density is strong but the portion size still deserves respect. There is more here than the main number alone, especially the protein (36% DV) and calcium (20% DV).
Worth knowing
High in saturated fat with 4.73g per 100g, which is worth watching if you are managing heart health or cholesterol.
Goji berries, dried holds its spot because 13g of dietary fiber is still comfortably strong. You are looking at 46% of the daily value per 100g, which is why it stands out in a nutrient-specific ranking like this. The extra protein (29% DV) and vitamin C (54% DV) help this entry hold up outside of the headline nutrient.
Wheat, soft white rounds out the ranking with 13g per 100g, which is still enough to be useful if it already fits your meals. That translates to 45% of the daily value, so it can materially move your intake in one serving. The extra protein (21% DV) and iron (30% DV) help this entry hold up outside of the headline nutrient.
Wheat, soft red winter lands lower on the page, but 13g per 100g is still better than what you get from most foods. 45% of the daily value is enough to make this a serious contributor rather than a token source. There is more here than the main number alone, especially the protein (21% DV) and magnesium (30% DV).
Nuts, almonds is here because even the back half of this list still offers respectable dietary fiber density. That translates to 45% of the daily value, so it can materially move your intake in one serving. At 579 kcal per 100g, the nutrient density is strong but the portion size still deserves respect. The extra protein (42% DV) and iron (21% DV) help this entry hold up outside of the headline nutrient.
