With good nutrition and lifestyle you can live well to the very end. In this booklet you will learn how to use diet as the foundation of a strong immune system, in connection with other lifestyle factors like temperance, water, exercise, positive thoughts, and balance between work and rest. This will optimise your ability to fight infection and enjoy a measure of good health. The food we eat means a lot to our immune system. Some foods build our immune system while other foods destroy it. Knowing what to eat, when to eat, what not to eat and how to prepare good food could be just what you are missing to reclaim your lost immunity.
