What to expect

Brought to you by Penguin.

The immune system is our most valuable resource – our first and main line of defence. It is protecting us around the clock without us even being aware! Environmental toxins, poor diet and nutrition, allergens, chronic stress, unresolved infections and imbalanced gut bacteria are believed to be the root cause of almost all immune issues and disorders. By eliminating these aggressors, and improving immune health through diet, nutrition and lifestyle alterations, research shows that you can improve immune function.

The Immunity Plan provides an engaging and accessible explanation of the latest and most robust science behind the immune system, including how women and men are affected differently and the importance of the gut microbiome, followed up with a plan that includes improving gut health, managing chronic stress, and the power of exercise.

This practical guide, complete with immunity supporting recipes, will give you the tools to understand what you can do to help support your immunity, reduce inflammation, and decrease your risk of developing an autoimmune disease.
