Bacteria may actually be your best friend.


We've all seen it in the commercials. We've all heard it from our academic counselors and teachers:

Germs--Namely bacteria--is bad. Stay away and disinfect disinfect disinfect! However, the human digestive system contains trillions of beneficial bacteria. These bacterial cells have the ability to break down indigestible substances within our bodies. An attribute that we as humans do not have. Not only does bacterial help breakdown indigestible substances, they also help decompose dead organisms. Having too less of (beneficial) bacteria may also lower our immune systems as humans--With too sterile of an environment, we would not be able to adapt to the smallest bit of bacteria.
