Despite its many health benefits, fiber is lacking in the typical American diet. In fact, the average daily intake of fiber is so low the USDA considers it a public health concern. Here's why fiber is so important, and the foods to prioritize to make sure you're getting enough of it.

Benefits of fiber

Plus, "fiber aids in the reduction of total and LDL cholesterol4 by binding to cholesterol in the gastrointestinal tract and moving it out of circulation," says registered dietitian and nutritionist Maya Feller, M.S., R.D., CDN. "These actions reduce the risk of developing cardiovascular disease and type 2 diabetes5," Feller says. 

It also helps your digestion run smoothly. Eating fiber can also help promote bowel regularity and support a healthy weight.6 It may even reduce the risk of certain cancers7, according to clinical research.

Oats 

Fiber: 8 to 16 grams per cup.

A standard serving size of steel cut oats is 1/4 cup, and a standard serving size of old fashioned rolled oats is 1/2 cup.

Start your morning off with 1 cup of steel cut oats, and you're already at 16 grams of fiber, according to Feller. Add blueberries or strawberries to the mix for an added boost.

2.

Buckwheat

Fiber: 17 grams per cup.

"When compared to other grains," registered dietitian Nour Zibdeh, M.S., RDN, says "buckwheat—which is technically a seed—has more fiber and protein." Just 1 cup contains 17 grams of fiber.

3.

Barley

Fiber: 6 grams per cup.

Barley is a type of grain, commonly used as a base for grain bowls. If you're able to tolerate gluten, eating 1 cup of cooked barley will give you about 6 grams of fiber. 

4.

Quinoa

Fiber: 4 grams per cup.

Quinoa is a whole grain, which means it's naturally high in fiber. According to registered dietitian Isabel Smith, R.D., CDN, there are four varieties of quinoa: white, red, black, and tricolor. White is the most common, and it contains about 4 grams of fiber per cup.

Fruits

Avocado 

Fiber: 13.5 grams, one avocado.

"Avocado is rich in insoluble fiber," research specialist in oncology nutrition L.J. Amaral, M.S., R.D., CSO, says. "And it contains 13.5 grams of total dietary fiber." Eat it on its own with sea salt and red pepper, or mash it on top of whole wheat bread for extra fiber.

6.

Apples

Fiber: 4.4 grams, one medium apple.

7.

Berries

Blackberries and raspberries both provide about 8 grams of fiber per cup, while blueberries provide 4 grams. The berries are also a good source of polyphenols, which play a role in metabolism, as well as chronic disease and weight management.

10.

Guava

Fiber: 9 grams per cup.
