When it comes to your body, your gut is at the epicentre of the action. It’s your largest interface with the outside world, it’s home to trillions of health-supporting bacteria and it’s also where most of your immune system hangs out. What this means is that if something isn’t quite right in your gut, it can affect many aspects of your health. In fact, burgeoning research suggests that gut health is implicated in heart disease, type-2 diabetes, depression, autoimmune disease and many other conditions.
