As well as digesting your food, our digestive systems play a critical role in the overall effectiveness of our immune system. In fact, your digestive system houses 70% of the immune system’s cells and hosts the gut microbiome.
Within the intestinal tract, friendly gut bacteria interact with immune cells; teaching the immune system how to behave and respond appropriately to potential danger. By working together the intestinal tract, the gastrointestinal immune cells and the gut microbiome support immune defences. (see references)
