The Importance of Fiber for Gut Health
Fiber plays a crucial role in maintaining gut health by aiding in regular bowel movements. It consists of carbohydrates that are not digested by the body, contributing to the weight and size of stool. Studies indicate that fiber can significantly accelerate the time it takes for food to pass through the gut, potentially decreasing transit time by up to 24 hours. This process not only helps prevent constipation but also promotes a balanced gut microbiome by providing nourishment for beneficial gut bacteria.
