Abstract

Dietary fiber is critical for gut health, impacting the microbiome, satiety, and nutrient absorption, and is linked to preventing chronic diseases like type 2 diabetes, cardiovascular disease, and certain cancers. Fiber influences gut microbiota composition by selectively feeding beneficial bacteria that produce short-chain fatty acids (SCFAs). It improves glycemic control and insulin sensitivity, reducing type 2 diabetes risk, and contributes to cardiovascular health by lowering blood pressure and LDL cholesterol. Fiber intake is associated with a reduced risk of colorectal cancer and aids in weight management through increased satiety. Different fiber types have varied effects on the gut microbiome, and synergistic interactions with other nutrients are being explored. Recommended intake is 25-30 grams daily, with gradual introduction and hydration advised
