Fiber is not a source of energy for the body.

Question

BlackTom AI · Accepted Answer

Statement overview: The claim presented is 'Fiber is not a source of energy for the body.' We will evaluate both possible options to understand why one is correct and the other is not.
Option True: Saying that fiber is not a source of energy aligns with the general nutrition principle that most dietary fiber is not digestible by human enzymes. Therefore, it does not contribute calories in the typical sense. Some fiber can be fermented by gut bacteria to short-chain fatty acids, which provide a small amount of energy, but this contributes only a modest amount and is not counted as a primary energy source. In many educational contexts, fiber is treated as not a significant energy source for humans, so labeling it as not energy-providing is largely acceptable.
Option False: If one claims that fiber is a source of energy in the same way as carbohydrates, fats, or proteins, this would be inaccurate. While microbial fermentation does yield minor energy, the majority of fiber is not digested to yield usable calories for the human host, and thus its role as an energy source is negligible rather than principal. This option would misrepresent standard nutrition science about caloric contribution from fiber.
Option nuance: A careful interpretation recognizes the nuance that trace energy can be obtained via fermentation, but this does not amount to fiber being a primary energy source. Treating fiber as energy-providing would ignore the dominant metabolic reality that human enzymes cannot break down most fibers, and energy contribution remains minimal compared to digestible macronutrients.
Option implications: If a test question seeks a straightforward true/false answer, the conventional stance is that fiber does not serve as a primary energy source, supporting the True choice. Conversely, labeling fiber as a significant energy source would be misleading and contrary to standard dietary guidelines.
In summary, the claim reflects the conventional view in nutrition that fiber is not a meaningful energy source for the body, with only a minor energy contribution via fermentation exceptions. The alternative perspective overstates fiber’s caloric role and is therefore incorrect.
