Question: 1 / 400

What is the primary role of fiber in the diet?

Providing energy

Enhancing protein intake

Regulating digestion

The primary role of fiber in the diet is to regulate digestion. Dietary fiber, found in fruits, vegetables, whole grains, and legumes, adds bulk to the stool and helps facilitate regular bowel movements. It aids in preventing constipation, promoting a healthy gut environment, and supporting the growth of beneficial gut bacteria. Additionally, certain types of fiber can help in moderating blood sugar levels and lowering cholesterol, which contributes to overall digestive health.

Fiber is not a source of energy, as it is not digested by the body in the same way that carbohydrates, fats, and proteins are. It also does not enhance protein intake, as that is the function of protein-rich foods. While some fiber sources may contain vitamins, fiber itself is not a direct supplier of essential vitamins. Its primary function remains centered around digestion and the maintenance of gut health.
