Fiber refers to a type of carbohydrate that is not digestible by the human body. It is a crucial component of a balanced diet, primarily found in plant-based foods. Fiber aids digestion and contributes to overall gut health by promoting regular bowel movements and preventing constipation. It can be classified into two main types: soluble and insoluble fiber. Soluble fiber dissolves in water and can help lower blood cholesterol and glucose levels, found in foods like oats, beans, and fruits. Insoluble fiber does not dissolve in water and adds bulk to the stool, helping food pass more quickly through the digestive tract, present in whole grains, nuts, and vegetables. Adequate fiber intake is associated with various health benefits, including reduced risk of heart disease, diabetes, and certain types of cancer. It is recommended to consume a variety of fiber sources to maximize its health benefits.
