What important role does fiber play in body functions?

1. Energy production

2. Metabolism regulation

3. Proper digestion

4. Skin health

The correct answer is: Proper digestion

Fiber plays a vital role in proper digestion by adding bulk to the stool, which promotes regular bowel movements and helps prevent constipation. It aids in the movement of food through the digestive tract, allowing for efficient nutrient absorption and overall gut health. By facilitating smooth digestion, fiber can also help prevent various gastrointestinal disorders, making it essential for maintaining a healthy digestive system. While energy production and metabolism regulation are critical body functions, these primarily involve macronutrients like carbohydrates, proteins, and fats. Skin health is influenced by various factors, including hydration and nutrients, but is not directly impacted by fiber in the same way that digestion is. Thus, fiber's primary significance lies in its contribution to digestive health and maintaining a well-functioning gastrointestinal system.
