Hi, Jon, me again! After surgery your body will kind of be the boss and you will know what you can and can't do. One needs to stay away from grease, fatty foods, fried foods and in some cases dairy. My husband was a chocoholic and couldn't stand sweets after surgery. An older but still exceptional book to get on nutrition would be the Anticancer: A New Way Of Life - David Servan-Schreiber.
