I am a bodybuilder who is an ex smoker, and I want to put on muscle
whilst inhibiting tumors.  Bodybuilding works best with lots of
energy and protein, and from what I have seen, cancer prevention
requires low energy with range of different fruit and veg.  They are
diametrically opposed - any suggestions?

My current strategy:

Low calorie intake (c1000cal) for last 5 years
20 portions of fruit and veg per day at c. 1hr intervals
Small highly bioavailable protein
Generally healthy living

I am about 200lb

Any suggestions, ideas, and thoughts welcomed!

thanks in advance
