High Fiber Foods


Fiber is an important part of a healthy balanced diet. It can help prevent heart disease, diabetes, weight gain and some cancers, and can also improve digestive health. The average intake of fiber is at least 30g a day. For children it is recommended the average amount of dietary fiber per day should be:

  • Women: 25 grams
  • Men: 35-40 grams
  • 2-5-year-olds: about 15g
  • 5-11-year-olds: about 20g
  • 11-16-year-olds: about 25g
  • 16-18-year-olds: about 30g

What is dietary fiber?

Dietary fiber, also known as roughage or bulk, includes the parts of plant foods your body can’t digest or absorb. Unlike other food components, such as fats, proteins or carbohydrates — which your body breaks down and absorbs — fiber isn’t digested by your body. Instead, it passes relatively intact through your stomach, small intestine and colon and out of your body.

Fiber is commonly classified as soluble, which dissolves in water, or insoluble, which doesn’t dissolve.

Soluble fiber. This type of fiber dissolves in water to form a gel-like material. It can help lower blood cholesterol and glucose levels. Soluble fiber is found in oats, peas, beans, apples, citrus fruits, carrots, barley and psyllium.

Insoluble fiber. This type of fiber promotes the movement of material through your digestive system and increases stool bulk, so it can be of benefit to those who struggle with constipation or irregular stools. Whole-wheat flour, wheat bran, nuts, beans and vegetables, such as cauliflower, green beans and potatoes, are good sources of insoluble fiber.

Most plant-based foods, such as oatmeal and beans, contain both soluble and insoluble fiber. However, the amount of each type varies in different plant foods. To receive the greatest health benefit, eat a wide variety of high-fiber foods.

Benefits of dietary fiber

Dietary Fiber Keeps Cholesterol Down

Fiber helps your cholesterol levels by blocking harmful cholesterol from making it into the bloodstream. Specifically it’s the soluble fiber that does the most work in this department. Soluble means it’s soaked up by the body rather than insoluble, which remains undigested during its trip through the body.

Dietary Fiber Helps Control Blood sugar

In people with diabetes, fiber — particularly soluble fiber — can slow the absorption of sugar and help improve blood sugar levels. A healthy diet that includes insoluble fiber may also reduce the risk of developing type 2 diabetes. A recent analysis of 19 studies, for example, found that people who ate the most fiber—more than 26 grams a day—lowered their odds of the disease by 18 percent, compared to those who consumed the least (less than 19 grams daily). The researchers believe that it’s fiber’s one-two punch of keeping blood sugar levels steady and keeping you at a healthy weight that may help stave off the development of diabetes.

Dietary Fiber Helps in Improving Heart Health

An inverse association has been found between fiber intake and heart attack, and research shows that those eating a high-fiber diet have a 40 percent lower risk of heart disease. For every 7 grams of fiber eaten daily, your risk of heart disease drops by 9 percent found a review of 22 studies published in the BMJ. That’s partly due to fiber’s ability to sop up excess cholesterol in your system and ferry it out before it can clog your arteries.

Researchers have found that for every seven-grams more fiber you consume on a daily basis, your stroke risk is decreased by 7 percent. Fiber helps you avoid a stroke by lowering the blood pressure. Cholesterol-lowering fiber sources like oatmeal are the best for reducing the likelihood of a stroke.

Dietary Fiber Helps Weight loss

Fiber supplements have been shown to enhance weight loss among obese people likely because fiber increases feelings of fullness. Eating the right amount of fiber each day contributes to your quest of maintaining a healthy weight. Not getting enough fiber causes you to store excess body waste and leaves you susceptible to toxic build-up, while making you less likely to have that get-up-and-go that leads to exercise and other activities.

Dietary Fiber Helps Improves Skin Health

Fiber, particularly psyllium husk, may help move yeast and fungus out of your body, preventing them from being excreted through your skin where they could trigger acne or rashes.

Dietary Fiber Reduce Risk of Certain Cancers

Fiber may not have been shown to directly responsible for cancer prevention, but it adds to a properly functioning body that is at a healthy weight and is keeping toxins from lingering around.

Every 10 grams of fiber you eat is associated with a 10 percent reduced risk of colorectal cancer and a 5 percent fall in breast cancer risk, says a study published in the Annals of Oncology. In addition to the anti-cancer effects of fiber, the foods that contain it—like veggies and fruits—are also rich in antioxidants and phytochemicals that could further reduce your odds.

Dietary Fiber Helps Keep Your Bowels and Colon Healthy

A high-fiber diet may lower your risk of developing hemorrhoids and small pouches in your colon (diverticular disease). Some fiber is fermented in the colon. Researchers are looking at how this may play a role in preventing diseases of the colon.

Dietary fiber increases the weight and size of your stool and softens it. A bulky stool is easier to pass, decreasing your chance of constipation. If you have loose, watery stools, fiber may help to solidify the stool because it absorbs water and adds bulk to stool.
