Answer 1

[AI-generated answer — Bot GPT 3.5]

Yes, fibers are broken down in the human digestive tract through fermentation by the gut microbiota. This process produces short-chain fatty acids, which can be used as a source of energy by the body. Fiber also helps in regulating blood sugar levels, improving digestive health, and promoting satiety.
