Feed Your Immune System

We know the immune system is important for staying healthy, but what exactly is it and what can we do to support it?

The immune system is a complicated network of cells, tissues and organs in your body that protect against infection and disease. Given that there are so many pieces to the puzzle, there’s not one easy fix that can transform a weak immune system into a strong one in a snap of the fingers, but nutrition certainly plays an important role in its function.
