When it comes to improving digestion and supporting overall wellness, fiber is a powerhouse nutrient. A diet rich in fiber not only ensures healthy bowel movements but also nourishes beneficial gut bacteria, reduces inflammation, and lowers the risk of chronic diseases like diabetes, heart disease, and obesity.
