If you’re new here, these three are the place to start — the foundations everything else builds on.
Date fiber shown with a wooden bowl heaped with plump glossy medjool dates, a few split open to show the inside
Do dates have fiber? Yes: one Medjool date has about 1.6 grams, and a quarter cup of chopped Deglet Noor dates has about 3 grams. They’re also very high in natural sugar, so a few dates go a long way.
Almond fiber shown with two bowls of whole almonds, a glass jar of smooth almond butter and loose almonds on linen
Do almonds have fiber? Yes: an ounce of raw almonds, about 23 nuts, has 3.5 grams, more than any other common nut. But almond milk and almond paste keep very little of it, so the form you choose decides how much fiber you get.
Pineapple fiber shown with a whole pineapple, a halved pineapple, golden wedges and a white bowl of pineapple chunks
Does pineapple have fiber? Yes: a cup of fresh pineapple chunks has about 2.3 grams for 83 calories. Canned pineapple has less fiber per bite, so fresh is the better pick if fiber is your goal.
Peanut butter fiber shown with an open jar of creamy peanut butter, a spoon, a slice of toast spread thick and peanuts
Does peanut butter have fiber? Yes, but not much: 2 tablespoons of smooth peanut butter have about 1.6 grams, and chunky has about 2.6 grams. It works best as a fiber helper alongside bread, fruit or oats rather than a main source.
Nut fiber shown with wooden bowls of almonds, cashews and mixed nuts on a light table with a few loose almonds around
Do nuts have fiber? Yes: most nuts give you about 2 to 3.5 grams per one-ounce handful, with almonds at the top and cashews near the bottom. The gap between the best and worst nut is almost fourfold, so the bag you reach for matters.
Green bean fiber shown with a wide bowl of fresh green beans and a smaller bowl of green beans behind it on a table
Do green beans have fiber? Yes: a cup of raw green beans has about 2.7 grams for 31 calories, and a cup of cooked frozen green beans about 3.8 grams. They’re a light, steady fiber source rather than a heavy hitter like dried beans.
Cherry fiber shown with a bowl of dark red sweet cherries with stems, loose cherries and a small dish of dried cherries
Do cherries have fiber? Yes: a cup of pitted sweet cherries has about 3.2 grams for 97 calories. Dried and canned cherries are a different story, so the form you buy changes how much fiber you actually get.
Bean fiber shown with bowls of dry black beans, red kidney beans and white navy beans with loose beans on the table
Do beans have fiber? Yes, plenty: half a cup of cooked navy beans has 9.6 grams and a cup of black beans about 15 grams. Beans are among the richest everyday fiber sources you can buy.
Chia seed fiber shown with a glass jar of chia pudding, small bowls of black chia seeds and a wooden spoon of seeds
How much fiber in chia seeds? One tablespoon has about 4.1 grams and a 1 ounce serving about 9.8 grams. By weight, chia is about one third fiber, more than flax and most nuts.
Celery fiber shown with a bunch of fresh celery stalks with leafy tops and a clear glass of cut celery sticks
Does celery have fiber? Yes: a medium stalk has about 0.6 grams and a cup of chopped celery about 1.6 grams, for just 14 calories. Celery is mostly water, so it adds fiber slowly, and juicing strips much of what’s there.
Cabbage fiber shown with a head of green cabbage, a halved red cabbage and a small bowl of pale shredded sauerkraut
Does cabbage have fiber? Yes: a cup of chopped raw green cabbage has about 2.2 grams for just 22 calories, and a cup of cooked savoy or red cabbage has about 4 grams. The amount shifts a lot between varieties, so the type you buy matters.
Tomato fiber shown with ripe red tomatoes on the vine, a halved tomato and a small bowl of dark sun-dried tomatoes
Do tomatoes have fiber? Yes, but not much when fresh: a medium raw tomato has about 1.5 grams. Concentrated forms change the picture, with a cup of canned tomatoes at about 4.6 grams and a cup of sun-dried tomatoes at 6.6 grams.
