Chickpeas are a fantastic source of dietary fiber. One cup of canned, drained chickpeas contains 16 grams of fiber (about two-thirds of the daily recommended intake for women and one-third of that recommended for men).
Bran cereal is one of the highest-fiber cold cereal options available. Depending on the brand, a 1-ounce serving of bran cereal can contain 6 (or more!) grams of fiber.
Raspberries provide 8 grams of fiber per 1-cup serving.6 Their combination of soluble and insoluble fiber adds bulk to the stool and promotes regular bowel movements.
You can find this high-fiber snack in the produce aisle already cooked and cooled, in the freezer section in steamable bags, or in the snack aisle in roasted form.
Chia seed pudding is another delicious, high-fiber snack you can prep in advance (for an even bigger fiber boost, add some blackberries).
