In fact, the average daily intake of fiber is so low, the United States Department of Agriculture (USDA) Dietary Guidelines considers it a public health concern. But why is fiber so important, and how can you make sure you’re getting enough? It has also been proven to reduce the body’s blood sugar response to certain foods, increase mineral absorption, and improve feelings of satiety. Plus, it helps your digestion run smoothly. The average American is eating about 16 grams of fiber2 daily, but according to Feller, “the recommended intake is 38 grams per day for men and 25 grams per day for women.” In order to fill what nutritionists call “the fiber gap,” consider adding these 25 foods to your diet. We consulted registered dietitians and the USDA Food Database3 to determine the best high-fiber foods. 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.

Try this: Chocolate buckwheat pancake recipe 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. 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.
