These organisms live inside us and on our skin, help digest food, fight off invaders, and even influence our behavior

It just so happens that we humans are never ever completely alone. No, I'm not talking about one organization's or another's knack for spying on us and keeping tabs on our routine, I'm talking about the army of creepy crawlers that we share our bodies with.

As explained in the video below, the average individual's body is home to about 100 trillion microorganisms. What this means is that there are 10 such buddies for each and every cell that is part and parcel of our anatomy.

These microorganisms form to so-called microbiome, and as shown by studies carried out over the years, they live both inside us and on our skin. They help us digest our food, make sure that the immune system is ready to fight off invaders and even influence our behavior.

Interestingly enough, it appears that a person's microbiome changes depending on what they choose to eat. Thus, healthy foods make for a healthy and complex microbiome, whereas pizza, hamburgers and the likes kill good bacteria in our bodies.

In fact, researchers say that this is the reason people who often snack on heavily processed foods tend to experience more health trouble such as allergies and autoimmune diseases than folks who stick to eating fruits and veggies.
