What is fiber?

• A. Fiber
• B. Protein
• C. Vitamin
• D. Fat

Answer: (A)

Fiber is a type of carbohydrate found in plant foods that the body cannot digest. It passes through the digestive system largely intact, adding bulk to stool and helping keep bowel movements regular. There are soluble and insoluble forms: soluble fiber dissolves in water and can help lower cholesterol and slow sugar absorption, while insoluble fiber adds bulk and speeds up intestinal transit. Because it is a carbohydrate that the body cannot digest, it does not provide calories like fats or proteins, and it is not a vitamin. This is why fiber is the correct description.
