But recently it occurs to me that taking an active care of my body doesnt hurt (esp after passing 25..)

So i wonder if anyone has a reading list / resources for the following:

1) any books/bibles for eating well (diet, nutrition, what to avoid) , and living well?

2) any books/bibles for cancer prevention ? (i am well and all but maybe i am actually doing something everyday without knowing to sabotage my body in 20 years?)

3) any clinic recommendations to do a full body check?

Thanks very much in advance :)
