Fiber intake refers to the amount of dietary fiber consumed by an individual in their daily food consumption. Fiber is a type of carbohydrate that is found naturally in many plant-based foods such as fruits, vegetables, legumes and whole grains. It is essential for maintaining good health as it promotes proper digestion, helps regulate blood sugar levels, lowers cholesterol and prevents constipation. Adequate fiber intake is important for overall well-being and can help prevent chronic diseases such as heart disease, diabetes and obesity.
