Final answer:
Fiber is not a good source of energy as it is not digested or absorbed by the body; instead, it helps with digestive health and cholesterol management.
Step-by-step explanation:
T/F: Fibre is a good source of energy: This statement is false. Fiber, while a carbohydrate, is not digested or absorbed by the human body, thus it does not supply energy like other carbohydrates such as sugars and starches do. The primary role of fiber is to provide bulk for the digestive tract muscles to work against, aiding in the passage of food through the gastrointestinal system.
Additionally, fiber acts like a sponge, absorbing unhealthy substances like cholesterol, preventing them from entering the bloodstream, and helping to reduce cholesterol levels. Although fiber is found in energy-containing foods like vegetables, fruits, and whole grains, it itself does not contribute caloric energy to our diets.
