A high-fiber diet positively impacts digestive health by promoting regular bowel movements and preventing constipation. Fiber increases stool bulk, which facilitates smoother passage through the gastrointestinal tract. Additionally, soluble fiber can improve gut health by acting as a prebiotic, feeding beneficial gut bacteria and enhancing the overall microbiome. This, in turn, can improve immune function and reduce inflammation. High-fiber foods, including fruits, vegetables, and whole grains, also contribute to better weight management by increasing satiety, leading to reduced overall calorie intake and improved health outcomes.
