Increasing fiber intake primarily helps to improve which bodily function?

1. Vision

2. Circulation

3. Digestion

4. Metabolism

The correct answer is: Digestion

Increasing fiber intake primarily helps to improve digestion. Fiber plays a crucial role in the gastrointestinal system by adding bulk to the stool, which facilitates regular bowel movements and helps prevent constipation. It also aids in the overall health of the digestive tract by promoting the growth of beneficial gut bacteria. Soluble fiber, for instance, can help to slow digestion and promote a feeling of fullness, which can be beneficial for weight management. While fiber can have positive effects on metabolism and overall health, its most significant and direct impact is on the digestive system. This is why the correct choice emphasizes the importance of fiber in maintaining digestive health and function.
