If you’re new here, these three are the place to start — the foundations everything else builds on.
Jackfruit fiber shown with a cut jackfruit revealing yellow pods and a bowl of shredded young green jackfruit
A cup of ripe jackfruit gives only about 2.3 grams of fiber, but young green jackfruit sold for vegan tacos lists about 7 grams per half cup. Which jackfruit you buy decides almost everything about its jackfruit fiber.
Fig fiber shown with fresh purple figs, a fig cut in half to show its pink seeded center and a bowl of dried figs
A quarter cup of dried figs gives about 3.7 grams of fiber, the most of any common dried fruit in the Dietary Guidelines tables. Figs fiber shrinks fast in processed snacks, though: two fig bar cookies can carry just 1 gram.
Passion fruit fiber shown with whole purple passion fruits and halves filled with yellow pulp and seeds with a spoon
A quarter cup of passion fruit pulp gives about 6 grams of fiber for 57 calories, more than a large apple. Nearly all of that passion fruit fiber travels with the seedy pulp, though: a cup of strained juice keeps less than half a gram.
Dragon fruit fiber shown with whole pink dragon fruit, a half showing white flesh and black seeds, and small cubes
A cup of dragon fruit gives about 3.2 grams of fiber for 122 calories, based on USDA survey data. Dragon fruit fiber varies a lot by product, though: frozen packs in USDA’s database list anywhere from 0 to 4 grams per serving.
Pomegranate fiber shown with whole pomegranates, one broken open to show red seeds, and a bowl of pomegranate arils
Half a cup of pomegranate seeds gives about 3.5 grams of fiber for 72 calories, and a full cup gives 7 grams. Pomegranate fiber lives in the seeds, though: a cup of bottled pomegranate juice has just 0.25 grams.
Guava fiber shown with whole green guavas and guavas cut in half to reveal pink flesh with a seeded center
One cup of fresh guava has 8.9 grams of fiber for 112 calories, more than a cup of raspberries. That guava fiber content puts it among the top fruits in federal food tables.
Papaya fiber shown with a ripe papaya cut in half showing black seeds, a papaya slice and a bowl of orange cubes
One cup of fresh papaya cubes gives about 2.5 grams of fiber for 62 calories. Papaya fiber is modest per bite, but per calorie fresh papaya outscores apples and oranges, and it brings nearly a full day of vitamin C.
Plum fiber shown with ripe purple plums, one plum cut in half to show the flesh, and a bowl of dark prunes behind
Two medium fresh plums give about 2 grams of fiber, while a quarter cup of prunes gives 3.1 grams. The plums fiber content jumps fivefold per 100 grams once the fruit is dried, yet per calorie fresh and dried plums are almost dead even.
High fiber bread shown with a seeded whole grain loaf and thick slices fanned out on a wooden cutting board by a window
The high fiber bread with the most per slice in our comparison is a pale keto loaf, Oroweat Keto, at 8 grams. Among whole grain loaves, Dave’s Killer Bread Powerseed leads with 6 grams, while many popular slices give 1 to 3.
High fiber snack bars shown as stacked oat and fruit bars on a white plate with a few almonds and dried cranberries
The best high fiber snack bars give 6 to 9 grams per bar, led by Fiber One Oats and Chocolate at 9 grams. Most classic granola bars give 2 to 3, and nearly all the top scorers get their fiber from chicory root.
Meal replacement shake with fiber shown in a glass with a straw beside a white shaker bottle and a ripe banana
Most meal replacement shakes fiber counts sit at about 5 grams per serving. Garden of Life’s organic powder leads our list with 8 grams, while a shake sold as “with Fiber” gives only 3.
Smoothie mix with added fiber shown as a tall pink berry smoothie with a spoon of powder and fresh berries beside it
The best fiber smoothie mixes give 5 to 7 grams per serving, but plenty of popular powders give 1 gram or none at all. A packet of Kuli Kuli Dark Chocolate leads with 7 grams, while a classic strawberry mix gives 0.
