If you’re new here, these three are the place to start — the foundations everything else builds on.
Chickpea fiber shown with a large bowl of cooked golden chickpeas, a smaller bowl behind and a dish of chickpea flour
Do chickpeas have fiber? Plenty: a cup of chickpeas boiled from dry has 12.5 grams. A rinsed cup from a can has 9.6 grams, and chickpea flour has four times the fiber of white flour.
Cashew fiber shown with a bowl of roasted cashews, a small glass jar of creamy cashew butter and loose cashews nearby
Do cashews have fiber? Yes, but not much: an ounce of raw cashews has about 0.9 grams for 157 calories. Cashews earn their place for copper and magnesium rather than fiber.
Kiwi fiber shown with whole fuzzy brown kiwis, a halved kiwi showing bright green flesh and black seeds, and thin slices
How much fiber in kiwi? About 2.2 grams in one green kiwi and 4.4 grams in two, for 90 calories. Two a day is also the amount researchers tested for constipation relief.
Zucchini fiber shown with whole green zucchini, a few round slices and a bowl of spiralized zucchini noodles
Does zucchini have fiber? A little: a cup of sliced raw zucchini has about 1.1 grams for 19 calories. It’s mostly water, so it shines for volume and vitamin C rather than fiber.
Oat fiber shown with small bowls of rolled oats and oat bran on a wooden tray next to a tall glass of oat milk
Does oat have fiber? Whole oats do: a cup of dry oats has about 8.1 grams. How much reaches you depends on the form, from oat bran at the top to oat milk, which keeps only about 1.2 grams per cup.
Kale fiber shown with a bunch of fresh curly green kale and a blue bowl of tender sautéed kale in front of it
Does kale have fiber? Yes: a cup of cooked kale has about 4.7 grams for just 43 calories. Raw or cooked, kale carries about 4 grams per 100 grams, and it comes with a huge dose of vitamin K.
Hummus fiber shown with a bowl of creamy hummus pooled with olive oil, a few whole chickpeas and fresh carrot sticks
Does hummus have fiber? Yes: a quarter cup of store-bought hummus has about 3.4 grams. Scoop for scoop it even edges out plain chickpeas, though it brings about twice the calories.
Asparagus fiber shown with a plate of roasted green asparagus spears and a bundle of fresh spears behind it
Does asparagus have fiber? Yes: a cup of cooked asparagus has about 2.9 grams for only 32 calories. It’s a moderate source rather than a high one, but it brings an unusually big dose of folate and vitamin K.
Onion fiber shown with a whole yellow onion, a halved red onion and a small metal pan of soft caramelized onions
Do onions have fiber? Yes, but not much per bite: a medium raw onion has about 1.9 grams for 44 calories. Green onions carry more per gram, and a cup of cooked onions holds about 2.9 grams.
Berry fiber shown with three small bowls of raspberries, blueberries with blackberries, and fresh red strawberries
Do berries have fiber? Yes, and some are among the richest fruits you can buy: a cup of raspberries has 8 grams. Others carry far less, with strawberries at 3 grams a cup and mulberries closer to 2.4.
Bell pepper fiber shown with whole yellow and red bell peppers, a halved red pepper and a few thin pepper strips
Do bell peppers have fiber? Yes: a cup of chopped raw red bell pepper has about 3.1 grams for just 39 calories. Color matters, since green peppers carry a little less and yellow ones less than half as much per gram.
Quinoa fiber shown with a bowl of fluffy cooked quinoa and a small dish of dry white and red quinoa seeds beside it
Does quinoa have fiber? Yes: a cup of cooked quinoa has about 5.2 grams, along with 8 grams of complete protein. A cup of dry quinoa lists about 12 grams, because it cooks up into roughly three cups.
