How does fiber support digestive health?

Fiber plays a crucial role in supporting digestive health by promoting regular bowel movements. This is primarily achieved through its ability to add bulk to the stool, which helps to stimulate the intestines and facilitate the passage of waste. There are two main types of fiber: soluble and insoluble. Insoluble fiber, found in whole grains, nuts, and vegetables, does not dissolve in water and is vital for adding bulk to the stool, which helps to prevent constipation. Soluble fiber, found in foods like oats and beans, can help regulate digestion and can also aid in managing cholesterol levels.

Regular bowel movements are important because they help to prevent issues such as constipation and promote overall gut health. A diet rich in fiber encourages a healthy microbiome and can decrease the risk of developing digestive disorders.

The other choices do not accurately depict the beneficial role of fiber in digestive health. Increasing sugar absorption is not a function of fiber; rather, fiber can slow the absorption of sugars, helping to regulate blood glucose levels. Reducing protein intake is unrelated to fiber's function, as fiber can coexist with a balanced diet including protein. Lastly, fiber does not prevent hydration; in fact, it often requires adequate fluid intake to function effectively in the digestive system.
