what is a fiber? in details

Answer:
Explanation:
Dietary fiber or roughage is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes.
Many of us associate fiber with digestive health and bodily functions we’d rather not think about. However, eating foods high in dietary fiber can do so much more than keep you regular. It can lower your risk for heart disease, stroke, and diabetes, improve the health of your skin, and help you lose weight. It may even help prevent colon cancer.
Fiber, also known as roughage, is the part of plant-based foods (grains, fruits, vegetables, nuts, and beans) that the body can’t break down. It passes through the body undigested, keeping your digestive system clean and healthy, easing bowel movements, and flushing cholesterol and harmful carcinogens out of the body.
Fiber comes in two varieties: insoluble and soluble.
Insoluble fiber does not dissolve in water. It is the bulky fiber that helps to prevent constipation, and is found in whole grains, wheat cereals, and vegetables such as carrots, celery, and tomatoes.
Soluble fiber dissolves in water and helps control blood sugar levels and reduce cholesterol. Good sources include barley, oatmeal, beans, nuts, and fruits such as apples, berries, citrus fruits, and pears.
Many foods contain both soluble and insoluble fiber. In general, the more natural and unprocessed the food, the higher it is in fiber. There is no fiber in meat, dairy, or sugar. Refined or “white” foods, such as white bread, white rice, and pastries, have had all or most of their fiber removed.
