I have been online reading a lot about diet, exercise, and other changes I can make to help my body become more cancer-proof. I have already read some of your posts about an alkaline diet and other research. Then there are those of you who are living life as usual but in moderation. I have seen articles online about natural things like shitake mushroom supplements for immune support. Also I have heard about graviola and apricot kernals. What is the story on these? I plan on eating healthier and exercising more as my doctor has recommended, but I wonder if these other things are just snake oil.
