Lightening the Load.
From before my illness, I have been a vegan. Aka I don’t eat meat or a lot of the bad things (Sugar, Alcohol etc). Like Judi Z said about removing toxins from the body, meat, sugar and the rest take a lot to digest and eliminate. Having lighter vegetarian foods support the immune system and by digesting easier, allow your body more time and energy to heal.
After the ivig and pain meds are done, mainstream medicine is out of bullets. That is were alternative medicine takes over.
