Your Immune System is in your GUT.
80% of your immune system lives in your gut and is home to a huge number of bacteria essential to your wellbeing. The immune system needs the right combination of good bacteria in the gut to function optimally.
By having good bacteria in your gut, the bad bacteria do not get a chance to multiply and cause disease. However, if the bad bacteria flourish and eliminate the good bacteria, your gut’s bacteria is then thrown out of harmony and your immune system is under pressure and open to those nasty invaders.
