Your gut (digestive system)
is a hub of wellness. It holds hundreds of trillions of bacteria that process food, dispatch protective nutrients and hormones through your system, and fight off inflammation that can lead to illness. Ideally, you want a ratio of 85 per cent good bacteria to 15 per cent not-so-good. If that balance is tipped too far the other way, things can get wonky.
