How does fiber contribute to digestive health?

Fiber plays a crucial role in digestive health primarily by aiding in regular bowel movements. It adds bulk to the stool and helps to retain water, which can make it easier to pass through the intestines. This process not only helps prevent constipation but also promotes overall digestive efficiency. A diet rich in fiber can encourage the growth of beneficial gut bacteria, contributing to a healthy microbiome and improved digestion.

In contrast, options that suggest fiber increases calorie intake, enhances nutrient absorption, or breaks down fats do not accurately reflect the primary functions of fiber in relation to digestive health. Fiber is known for its properties that help regulate digestion rather than increasing calorie intake or directly influencing the absorption of nutrients or fats. Therefore, recognizing fiber’s role in promoting regular bowel movements is central to understanding its contribution to digestive health.
