When these diverse communities are in synch they actually protect our bodies from invasion by harmful bacteria and viruses. As we assault our bodies with antibiotics, we are killing off this gut diversity and making it much easier for bad bacteria and viruses to colonize our interiors.
Attempting to protect ourselves from all the “germs” around us may be the wrong way to protect ourselves from the more dangerous and deadly viruses and bacteria around us. We should be aiming to enrich our gut’s diversity instead by feeding our critters by taking probiotics!
