The primary source of dietary fiber comes from plant-based foods. Fiber is found in fruits, vegetables, legumes, whole grains, nuts, and seeds. It plays a crucial role in maintaining digestive health by promoting regular bowel movements and preventing constipation. Additionally, dietary fiber can help regulate blood sugar levels, lower cholesterol, and contribute to a feeling of fullness, which may assist with weight management. There are two types of dietary fiber: soluble and insoluble. Both types are essential for a balanced diet and overall health, emphasizing the importance of consuming a variety of fiber-rich foods.
