It is not a matter of what you can and can't eat. You need to concentrate on building the bodies immune system up. Your diet provides the building blocks needed to do that. Eat a balanced diet that provides you with the nutrients needed to keep your body healthy.
If you happen to get knocked down a little and find yourself in poor health, you can then add chemicals and drugs to aid in helping your bodies immune system.
If your diet is high in anti oxidants and you want to try oxidation therapy, you simply need to increase the amount of oxidation used understanding that it will first react with the anti oxidants. An example of this is ascorbic acid. Ascorbic acid is considered an anti oxidant, but it is used as an activator for sodium chlorite and it works very well.
