Fiber might be one of the least exciting nutrients, but it's one of the most important.

The first thing to know about fiber’re likely not consuming nearly enough of the stuff. The Academy of Nutrition & Dietetics advises that most men try to eat about 38 grams of fiber per day, yet most guys only get about 15 grams per day.

Second, fiber is hugely beneficial for a multitude of reasons.

“There are two types of fiber: soluble and insoluble. Together, these are called ‘dietary fibers,’” says Karolin Saweres, R.D.N, L.D. Soluble fiber has been proven to lower blood cholesterol levels and the risk of heart disease, while insoluble fiber helps to lower the risk of diverticular disease, she adds.

Dietary fibers are found in the leaves, stems, and roots of plants. They’re unique because they hang out in your tract for nearly the entire digestive process, which helps keep things regular (yes, we're talking about poop).

Best of all, eating more fiber can make you feel fuller, longer. That’s because fiber absorbs water and expands in your gut, according to Jessica Bachman, R.D., Ph.D. She says that a good source of fiber should provide about 10 percent of your daily recommended intake per serving.

So how do you get all of that in?

“Eat at least one to two servings of [one of] these foods at every meal, and include them in all your snacks,” she says. One or two of the foods on this list require a slightly heftier serving to experience the full benefits—namely, almonds and chia seeds. Not to worry: Our experts have provided clever ways to pack them into your meals.

Read on for our list of the 30 best high-fiber foods.

“Black beans are a source of anthocyanins, the compound that gives them the deep purple color,” says Marisa Moore, R.D.N., “which are one of the more active antioxidants that may help reduce the risk of heart disease.” Bonus: they’re a great plant protein.

Moore recommends making them into a black bean burger, or tossing them into salads or atop a grain bowl.

Fiber: 8 grams

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.

oatmeal high in fiber

Serving size: ½ cup dry
Fiber: 4 grams

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

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.
