Dietary fiber is a type of carbohydrate that the body cannot digest, found mainly in plant-based foods. It plays a vital role in promoting digestive health, controlling blood sugar levels, and reducing cholesterol. There are two types of fiber: soluble and insoluble, both offering unique benefits.
Soluble fiber dissolves in water and forms a gel-like substance in the gut, helping to lower cholesterol and regulate blood sugar. Insoluble fiber, on the other hand, adds bulk to stool and aids in preventing constipation.
A high-fiber diet is associated with a reduced risk of heart disease, diabetes, and obesity. However, sudden increases in fiber intake can lead to bloating or gas.
