What is the role of fiber in a balanced diet?

A key role of fiber in a balanced diet is its contribution to digestive health. Fiber aids in digestion primarily by adding bulk to the stool, which can help maintain regular bowel movements and prevent constipation. It also promotes the growth of beneficial gut bacteria, which play a significant role in digestion and overall gut health.

Additionally, fiber can help regulate blood sugar levels and lower cholesterol, further underscoring its importance in a balanced diet. The inclusion of fiber-rich foods, such as fruits, vegetables, whole grains, and legumes, is essential for maintaining not only digestive health but also overall well-being. This makes fiber integral to a healthful diet, emphasizing its role beyond mere nutrient provision.
