What nutrient helps in regulating digestion and preventing constipation?

Dietary fiber plays a crucial role in regulating digestion and preventing constipation. It is a type of carbohydrate that the body cannot digest, which means it passes through the digestive system largely intact. This bulk helps to form stools and promotes regular bowel movements. As dietary fiber absorbs water, it softens the stool, making it easier to pass. A diet rich in fiber can prevent constipation and may help maintain overall digestive health by promoting the growth of beneficial gut bacteria.

In contrast, protein, saturated fat, and sugar do not provide the same benefits for digestion. While protein is essential for growth and repair, it does not significantly impact bowel regularity. Saturated fat can contribute to various health issues and does not aid in digestion. Sugar, particularly in excess, can lead to digestive problems, including constipation, because it may lack the fiber needed to support healthy digestion.
