Bacteria Eat What Our Body Leaves Behind
While a lot of the food we eat can be broken down and absorbed by our body, a significant amount can’t be. Dietary fiber, for example, can’t be digested by the human body but can be digested by bacteria. The bacteria in your body will scavenge whatever they get their hands on that our body leaves behind. In this way, they don’t harm us by stealing nutrients we need. Instead, they help to make sure there’s as little food wasted as possible.
