Which of the following is a benefit of dietary fiber?

Dietary fiber plays a crucial role in promoting gastrointestinal health. It is known for its ability to add bulk to the stool, which aids in regular bowel movements and can prevent constipation. Moreover, fiber helps to maintain a healthy gut microbiome by serving as a food source for beneficial bacteria in the intestines, which can enhance overall digestive function and improve nutrient absorption.

In addition to helping with bowel regularity, fiber can also contribute to the prevention of various digestive disorders, such as diverticulitis and hemorrhoids. By promoting a healthy digestive system, dietary fiber supports overall wellbeing and can reduce the risk of certain chronic diseases, including heart disease and type 2 diabetes.

The other options do not accurately represent the benefits of dietary fiber; instead, they describe outcomes that are not associated with fiber's effects on health.
