Question

BlackTom AI · Accepted Answer

Consider the statement about dietary fiber: it describes dietary fiber as indigestible carbohydrates that provide health benefits throughout the digestive tract and cannot be broken down by enzymes in our body.
Option 1: True. This aligns with the standard definition of dietary fiber in nutrition science. Dietary fiber consists of carbohydrate polymers that humans lack the enzymes to digest, which is why they pass through the small intestine largely intact. Their health benefits arise as they interact with the gut, contribute to stool bulk, and, for certain fibers, are fermented by gut microbiota to produce beneficial short-chain fatty acids. This statement accurately captures both the indigestibility and the health-beneficial aspects across the digestive tract.
Option 2: False. This would be incorrect because the core aspect of dietary fiber is precisely that humans do not enzymatically digest these carbohydrates. While some fibers are fermented by gut bacteria, that fact does not contradict the overall definition; it rather explains part of how fiber exerts health benefits. The claim that dietary fiber can be broken down by human enzymes is not accurate, which makes this option misleading.
In summary, the statement correctly reflects the fundamental properties of dietary fiber: indigestible by human enzymes and capable of delivering health benefits along the digestive tract. The false option misstates the fundamental enzymatic indigestibility and would mislead about how fiber is processed in the body.
