Fiber is a type of carbohydrate found in plant foods that the body cannot digest. Unlike other carbohydrates, such as sugars and starches, fiber passes through the digestive system mostly intact. It comes in two main types: soluble fiber, which dissolves in water, and insoluble fiber, which does not. Foods high in fiber include fruits, vegetables, whole grains, legumes, and nuts.
Fiber is important for overall health because it helps regulate the body’s digestive system. It can promote a feeling of fullness, which can help with portion control and weight management. Additionally, a diet high in fiber is linked to a lower risk of certain diseases such as heart disease, diabetes, and some types of cancer. It also supports healthy gut bacteria, which play a key role in digestion and immune function.
In the body, fiber serves several basic functions. It helps move food through the digestive tract, preventing constipation and promoting regular bowel movements. Soluble fiber can help lower cholesterol levels and stabilize blood sugar levels, while insoluble fiber helps add bulk to the stool. This makes fiber an essential part of a balanced diet, contributing to both digestive health and overall well-being.
Including a variety of fiber-rich foods in your diet can support health in numerous ways. It is advisable to gradually increase fiber intake to avoid digestive discomfort, and it is important to drink plenty of water when consuming high-fiber foods.
