Often mistaken for a grain, quinoa is technically a fiber-and protein-filled seed. “This pseudo-grain boasts five grams of fiber per cup, and works as a tasty addition to stir fry, formed into patties or burgers, or as part of a stew,” says Moore. Even better, one serving size also gives you 8 grams of protein.

Like other legumes, split peas offer a hearty dose of fiber and protein: a quarter cup offers 11 grams of protein. Plus, they’re low in fat but high in folate, potassium, and iron.

Not only does oatmeal lower LDL, or “bad” cholesterol, research suggests it also suppresses appetite, according to Harvard Health.

Not only will eating Brussels sprouts help you reach daily fiber goals, they could reduce prostate cancer risk, too. Research shows that cruciferous vegetables like Brussels sprouts, broccoli, and cauliflower contain a natural chemical that may prevent cancer from growing.

Serving size: 3.5 ounces (about two kiwifruits)

Fiber: 3 grams

Tasty and fiber-filled, golden kiwifruit are also called yellow kiwi and SunGold kiwi in supermarket aisles.

“Consuming two golden kiwifruits per day has been shown to effectively manage the symptoms of constipation,” says Kara Landau, R.D. at Gut Feeling Consultancy, adding that it’s a rich source of prebiotics, too.

Think of prebiotics as food for probiotics: while probiotics are live microorganisms, prebiotics are fermentable fibers that pass through your digestive system undigested, and then promote probiotic growth and activity.

Serving size: 1 large zucchini

Fiber: 3 grams

Michelle Saari, R.D., calls zucchini the perfect in-season spring or summer vegetable for its nutrients and low cost, and says that early research suggests it may have anti-cancer properties. “Throw it into a stir-fry, pasta, or roast it in a little bit of olive oil,” she suggests.

Fiber: 6 grams

Juicy and sweet, “pears are a great source of soluble fiber,” says Kim Kulp, R.D.N., a gut health expert. Kulp notes that this type of fiber does more than help with constipation: It can also lower cholesterol levels, keep you feeling full, and help control blood sugar. Try slathering some nut butter on a sliced pear for a quick and tasty snack.
