What is the role of dietary fiber in the digestive system?

• A. Promotes regular bowel movements
• B. Increases calorie intake
• C. Absorbs excess fat
• D. Enhances nutrient absorption

Answer: (A)

Dietary fiber plays a crucial role in promoting regular bowel movements, which is essential for maintaining digestive health. It adds bulk to the stool, making it easier to pass through the intestines, thus preventing constipation. Fiber is classified into two types: soluble and insoluble. Insoluble fiber, found in whole grains, nuts, and vegetables, adds bulk to the stool and helps food move through the digestive tract more quickly. Soluble fiber, found in oats, beans, and fruits, helps to regulate the body’s use of sugars and can assist in lowering blood cholesterol. By facilitating regular bowel movements, dietary fiber helps to maintain a healthy gut microbiome and may reduce the risk of developing gastrointestinal disorders and other health conditions, such as diverticulitis and colorectal cancer. This regularity is vital for overall digestive function and well-being.
