Dietary fiber is an essential component of a healthy diet. You’ve probably heard on several occasions that fiber is an essential component of every good diet and that it’s good for your health. But, why?
Dietary fiber is important to your health.
Dietary fiber — found mainly in fruits, vegetables, whole grains and legumes — is probably best known for its ability to prevent or relieve constipation. But foods containing fiber can provide other health benefits as well, such as helping to maintain a healthy weight and lowering your risk of diabetes, heart disease and some types of cancer.
Selecting tasty foods that provide fiber is not a difficult task. Find out how much dietary fiber you need, the foods that contain it, and how to add them to meals and snacks.
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.
Benefits of a high-fiber diet
The benefits of fiber are incredible to your body.
You can get fiber from:
Refined or processed foods, such as canned fruits and vegetables, pulp-free juices, white breads and pastas, and non-whole-grain cereals — are lower in fiber. The grain-refining process removes the outer coat (bran) from the grain, which lowers its fiber content. Enriched foods have some of the B vitamins and iron added back after processing, but not the fiber.
Another way to get more fiber is to eat foods, such as cereal, granola bars, yogurt and ice cream, with fiber added. The added fiber usually is labeled as “inulin” or “chicory root.” Some people complain of gassiness after eating foods with added fiber.
However, some people may still need a fiber supplement if dietary changes aren’t sufficient or if they have certain medical conditions, such as constipation, diarrhea or irritable bowel syndrome. Check with your doctor before taking fiber supplements.
Also, drink plenty of water. Fiber works best when it absorbs water, making your stool soft and bulky.
