If you’re new here, these three are the place to start — the foundations everything else builds on.
Swiss chard fiber shown with a bunch of rainbow chard with red and yellow stems beside a skillet of sauteed chard and beans
Yes. A cup of chopped, boiled Swiss chard has about 3.7 grams of fiber for only 35 calories. Swiss chard fiber comes with a big dose of vitamin K, magnesium and potassium.
Parsnip fiber shown with long cream colored parsnips on a baking tray beside golden roasted parsnip chunks
A cup of cooked parsnip slices has about 5.6 to 6.2 grams of fiber, and a cup of raw slices has about 6.5 grams. Parsnips fiber beats carrots, potatoes and most other root vegetables cup for cup.
Turnip fiber shown with whole white and purple-topped turnips with their leafy greens beside a bowl of roasted turnip cubes
Yes. A cup of boiled turnip cubes has about 3.1 grams of fiber for only 34 calories, and a medium raw turnip has about 2.2 grams. For more turnips fiber, eat the greens too: a cooked cup of turnip greens has 5 grams.
Spaghetti squash fiber shown with a roasted squash half as a fork lifts golden noodle-like strands from the flesh
Not especially. A cup of cooked spaghetti squash has about 2.2 grams of fiber for only 42 calories. Spaghetti squash fiber is modest, but the calorie and carb savings over pasta are big.
Collard green fiber shown with a bunch of large fresh collard leaves beside a clay bowl of cooked chopped collards
Yes. A cup of chopped, boiled fresh collard greens has about 7.6 grams of fiber for roughly 63 calories. Collard greens fiber drops to about 4.8 grams per cup when you start with frozen greens.
Jicama fiber shown with a whole brown jicama root beside a pile of peeled crisp white jicama sticks on a light table
Yes. A cup of raw sliced jicama has about 5.9 grams of fiber for only 46 calories, which is more than a cup of raw carrots. Jicama fiber also includes inulin, a carbohydrate researchers study for its prebiotic potential.
Butternut squash fiber shown with a squash cut lengthwise to show its orange flesh and seeds beside a bowl of roasted cubes
A cup of baked butternut squash cubes has about 6.6 grams of fiber for around 82 calories. Raw squash has less per cup, so butternut squash fiber is highest once it is roasted or baked.
Radish fiber shown with a bunch of round red radishes with green tops beside a small bowl of thin pink radish slices
Yes, a little. Radishes fiber comes to about 1.9 grams per cup of raw slices for just 19 calories, and daikon radish is similar. They are a small fiber source but one of the lightest ways to add crunch and volume to a meal.
Okra fiber shown with whole fresh green okra pods on a wooden board beside a bowl of sliced star-shaped okra rounds
Yes, for a vegetable this light. Okra fiber comes to about 4 grams per cooked cup for only 35 calories, and eight raw pods give you about 3 grams. That ties okra with green beans among everyday vegetables.
Mushroom fiber shown with white button and brown cremini mushrooms, whole and sliced, on a round wooden cutting board
Yes, though mushrooms fiber depends on cooking. A cup of raw white mushrooms has only about 1 gram of fiber, while a cup of cooked mushrooms has about 3.4 grams, because cooking shrinks them and packs more into the cup.
Eggplant fiber shown with a whole glossy purple eggplant beside a plate of grilled eggplant slices topped with herbs
Yes. Eggplant fiber comes to about 2.5 grams per cup, raw or cooked, for 20 to 35 calories, and a whole medium eggplant holds around 16 grams. How you cook it matters more for calories than for fiber.
Beet fiber shown with whole red beets with leafy green tops, a beet cut in half and a bowl of sliced deep red beets
A medium raw beet has about 2.3 grams of fiber, and a cup of sliced raw beets about 3.8 grams. Beets fiber content drops slightly when they’re boiled or canned, so raw and roasted beets give you the most per serving.
