Diet and healing

HapB

I have been doing research on diet and healing cancer. I just bought the Anti Cancer book and Dr. Joel Fuhrman's books. Has anyone tried any particular anti cancer diet and/or supplements?   Because this is my third unrelated cancer, I want to do all that I can to get healthy. I already had what I thought was a healthy diet, mostly plant based, no red meat, no processed foods, no alcohol, and no processed food. I may be eating the wrong things or not getting the right nutrients.  The hospital dietician for my last cancer, basically stuck to the standard food groups and helped me manange the diarreah caused by chemo and surgeries. I need more than that this time, but I don't know where to turn for reliable and evidence based information.

Does anyone have any information to share? Thanks.
