Fiber + Vegetables with Fiber

Yes, and more than almost any other vegetable. Artichokes fiber reaches about 6.8 grams in one medium boiled globe artichoke and 9.6 grams per cup of cooked hearts and leaf bases, ahead of peas, Brussels sprouts and broccoli.

Vegetable skins fiber can be surprisingly concentrated: USDA lists baked potato skin at 7.9 grams of fiber per 100 grams, close to boiled black beans and about five times the flesh. Not every peel works that way, though, and cucumber skin matters more for vitamin K than for fiber.

On baked vs boiled vegetables fiber, baked usually looks higher on the label, but mostly because baking drives water out while boiling soaks it in. Measured against the solid part of the vegetable, USDA numbers for squash and sweet potatoes come out almost identical either way, and the bigger fiber swing comes from keeping the skin on.

On raw vs steamed vegetables fiber, the total barely moves, but the type of fiber does. In a study of 29 vegetables, steaming shifted fiber from insoluble to soluble in most of them, nearly tripling soluble fiber in broccoli, and steamed broccoli kept more vitamin C than any other cooking method tested.

The best high fiber vegetables for weight loss are the non-starchy ones: cauliflower, broccoli, Brussels sprouts and leafy greens give 4 to 6 grams of fiber per cooked cup for under 70 calories. In a study of more than 133,000 adults, these vegetables were linked to weight loss over time, while corn, peas and potatoes were linked to small gains.

On fresh vs frozen vegetables fiber, frozen holds its own: USDA data show cooked frozen Brussels sprouts at 4.1 grams of fiber per 100 grams versus 2.6 for fresh, and most other vegetables land within half a gram. Here’s the side by side data, what happens to vitamins, and how to use frozen vegetables for easy meal prep.

On raw vs cooked vegetables fiber, cooking barely moves the grams: USDA data show carrots at 2.8 grams per 100 grams raw and 3.0 boiled, with most vegetables shifting by less than a gram. What cooking does change is water, volume and vitamins, so the method you choose matters more than whether you cook at all.

Cruciferous vegetables fiber ranges widely: a cooked cup of Brussels sprouts has 6.4 grams, broccoli 5.2 and cauliflower 4.9, while a cup of raw bok choy has under 1 gram. Here’s every common crucifer ranked, plus how cooking and portion size change the numbers.

On leafy greens vs root vegetables fiber, the answer flips depending on how you measure: cup for cup, roots like parsnips and sweet potatoes win with over 6 grams, but per calorie, cooked greens like turnip greens deliver more than five times the fiber. Here’s how they compare and when each makes sense.

Spinach fiber adds up to about 4.3 grams in a cup of cooked spinach, along with more than a third of your daily magnesium. Spinach wraps and pastas rarely deliver the same benefits, so cooked leaves are the form worth building meals around.
