[ELI5] If food is broken down by bacteria in our gut, how do we get energy from food?

305 viewsBiologyOther

Does the bacteria consuming it not use the energy generated? How do we even process it? Like what does the bacteria give off or stomach do that our body converts into energy?

Food is not broken down by bacteria in our gut.
The food we eat is digested in the stomach and small intestine, where most of the nutrients are also absorbed. Once the food reaches the colon, it’s basically just fiber and other minor stuff that you were not able to absorb. The bacteria in the colon then digest these leftovers, which actually produces some other things that are beneficial to us.

Your poop is basically fiber, water and bacteria from your gut.
