What is Fiber?
Understanding Dietary Fiber
Dietary fiber, often referred to as roughage or bulk, is the part of plant foods that our bodies cannot digest. Unlike other food components, such as fats, proteins, or carbohydrates, fiber isn’t broken down and absorbed by the body. Instead, it passes relatively intact through the stomach, small intestine, and colon, aiding various bodily functions.
Types of Fiber
Soluble and Insoluble Fiber
Fiber is generally classified into two types: soluble and insoluble.
- Soluble Fiber dissolves in water to form a gel-like substance. It can help lower blood cholesterol and glucose levels. Foods high in soluble fiber include oats, peas, beans, apples, citrus fruits, carrots, and barley.
- Insoluble Fiber promotes the movement of material through your digestive system and increases stool bulk. This type of fiber is beneficial for 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.
Health Benefits of Eating Fiber
Improves Digestive Health
Regular Bowel Movements
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.
Supports Heart Health
Lowers Cholesterol Levels
Soluble fiber found in beans, oats, flaxseed, and oat bran may help lower total blood cholesterol levels by lowering low-density lipoprotein, or “bad,” cholesterol levels. Studies have also shown that high-fiber foods may have other heart-health benefits, such as reducing blood pressure and inflammation.
Aids in Weight Management
Promotes Satiety
High-fiber foods tend to be more filling than low-fiber foods, so you’re likely to eat less and stay satisfied longer. This helps control your weight by reducing your overall calorie intake.
Controls Blood Sugar Levels
Regulates Blood Glucose
For 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.
Reduces the Risk of Certain Cancers
Colon Health
A high-fiber diet may lower your risk of developing colorectal cancer. Some types of fiber are fermented in the colon. Researchers are looking at how this might play a role in preventing diseases of the colon.
