My boyfriend is a healthy whit 45 years-old male who had bladder cancer a couple of years ago, but now recovered. He does smoke, but currently trying to quit. His diet is fairly good. Anyway, we are both very interested in a healthy diet and we would like to make whatever changes are needed to bring about optimum health. What kind of diet do we consider? Where can I find additional information on the diet, like recipes, shopping lists, etc?
