A high-fiber diet positively influences digestive health by promoting regular bowel movements and preventing constipation. Fiber adds bulk to the stool, making it easier to pass. Furthermore, it supports a healthy gut microbiome by serving as food for beneficial bacteria. This microbial activity can enhance nutrient absorption and reduce the risk of gastrointestinal issues, such as diverticulosis and colorectal cancer. Additionally, a high-fiber intake has been linked to improved blood sugar control and reduced cholesterol levels, further bolstering digestive and overall health.
