There are some resources here and also with the discussions on diet there were suggestions to go to the livestrong site or the MSK site.
Read a few and then select what works for you
Ok everyone I see statements that say change your diet and exercising can reduce your risk of recurrence. What should I change my diet to? Does anyone have any suggestions on diet?
depends on your perspective and how "rad" you wanna be. i was a long time vegetarian, but after my diagnosis, i completely kicked dairy to the curb. i read a book called the china study, and then i read more stuff related to that book... and learned a bunch about dairy etc... and pretty much went vegan immediately. my health care team were strongly supportive and said that calories from animal sources don't really do us much good at all.... i was in a clinical trial, and the head researcher was also my oncologist... and he said, with the exception of some fish, he didn't see the point of ever eating dairy or meat products of any kind. as for fish, there may be some beneficial things... but you can get those benefits from other sources without the potential problems (e.g., mercury).
so, eat a balanced diet... good fats like olive oil and avocado and nuts and related... loads of vegetarian proteins like beans and nuts and peas and related... and loads of nutrient-dense foods like cabbage and broccoli and blueberries and so on.... make sure you eat DELICIOUS food, because boring / tasteless foods make for diets that suck.
and don't forget chocolate - that's a food group, you know? dark delicious dairy-free chocolate... there are several fantastic chocolates available....
and... good luck!
