Dietary fiber is a type of carbohydrate that the human body cannot digest. Unlike other carbohydrates that are broken down into sugar molecules, fiber passes through the digestive system relatively intact. It is found mainly in fruits, vegetables, whole grains, and legumes. There are two main types of dietary fiber: soluble fiber, which dissolves in water, and insoluble fiber, which does not. Both types play important roles in maintaining health.
Dietary fiber is important for overall health because it helps regulate bowel movements and supports digestive health. Eating enough fiber can reduce the risk of developing various health issues, including constipation, heart disease, and type 2 diabetes. It can also aid in weight management by making you feel full longer, which may help prevent overeating. A diet rich in fiber is often associated with better cardiometabolic health, which includes factors like blood sugar and cholesterol levels.
In the body, dietary fiber functions primarily by adding bulk to the stool and promoting regular bowel movements. This helps prevent constipation and encourages a healthy gut microbiome. Soluble fiber can also help lower blood cholesterol levels and stabilize blood sugar by slowing down digestion. Overall, fiber plays a crucial role in maintaining gut health and supporting metabolic functions.
Including a variety of fiber-rich foods in your diet is a simple way to improve your overall health. While many people do not get enough fiber each day, making small changes, like choosing whole grain products or adding fruits and vegetables to meals, can help increase your intake.
