What Foods Have Fiber? 18 Fiber-Rich Foods and Health Benefits

Fiber Rich foods

Fiber may not sound as important as other components, but it is an essential part of a daily diet. It isn’t exactly a nutrient, but a type of carbohydrate that cannot be digested by humans. The most important benefit of fiber-rich foods is that they help in digestion. Before you know what foods have fiber, it is essential to know the types of fiber. Fiber is classified into two main types—soluble and insoluble.

Soluble fibers dissolve in water, whereas insoluble fibers don’t. Soluble fibers are found in oats, lentils, nuts and seeds, fruits such as apple, pear, strawberry, and blueberry, and many other ingredients. The sources of insoluble fiber include rice, whole grains, wheat bran, nuts and seeds, carrots, cucumber, grapes, tomatoes, and leafy veggies. Generally all plant-based foods are rich in fiber.

Nutritionists recommend consuming 20 to 30% soluble fiber out of the recommended total fiber intake per day.

Recommended Daily Intake of Fiber

How much fiber you should consume every day? In the U.S., an average adult consumes only 15 grams of fiber per day.

According to the National Academy Institute of Medicine, women younger than 50 years-old need 25 grams of fiber per day, while those above 50 should consume 21 grams of fiber per day. Men under 50 years-old should consume 38 grams per day, while those above 50 should consume 30 grams per day.

Health Benefits of Fiber Foods

The health benefits of fiber-rich foods depends on the type of fiber consumed. Soluble fiber fills you up while slowing digestion. This makes you feel full for a longer duration, which in turn helps in weight loss. It also helps regulate blood sugar, reduces cholesterol, lowers the risk of heart disease and type 2 diabetes.

Insoluble fiber makes food move quickly through the digestive tract, preventing constipation and also reducing the risk of diverticulitis by 40%. Remember to add fiber-rich foods to your diet gradually, especially if you are not used to it. For the first few days, you may experience bloating and gas. Gradually, those symptoms will fade away as your body gets used to consuming fiber.

Make sure you remain active and drink lots of water after consuming fiber-rich foods. This will help flush out the toxins and improve metabolism. If you don’t drink the required amount of water, you might get constipated.

Normally, none of us consumes excess fiber. But as a word of caution, consuming excess fiber can block your intestine and inhibit the smooth flow of food through the intestine. This will hinder the absorption of nutrients in the blood, and will lead to accumulation of toxins in the body. In this case, consult your doctor immediately. However, there’s no need to worry about this, as most of us barely manage to eat the required daily intake of fiber anyway.
