Q: Which type of carbohydrate cannot be broken down by the GI tract, does not provide energy, but helps the body get rid of wastes and keeps the intestinal tract healthy?
  • A. Starch
  • B. Glycogen
  • C. Sugar
  • D. Fibre
Correct Answer: Option D - Fibre is a type of carbohydrate that the body can't digest. Fibre cannot be broken down into sugar molecules, and instead, it passes through the body undigested. Humans lack the enzymes necessary to break down fibres. This characteristic of fibre contributes to various health benefits, such as aiding digestion and maintaining regular bowel movements. Dietary fibre comes from plant based foods that contain cellulose, hemicellulose, lignin, pectin, mucilage and gum.
