My doctor gave me a very simple guide to follow, Protein with every meal, no crackers, no chips, no cheese, no nuts and no high calorie Desserts. I have cheated with the chips even the day of my surgery, I think I needed the salt. Everything else is fine he did say some people have difficulty with soft bread and rice but he didn't say to not eat them. I am not buying anymore chips so I won't be tempted and the funny thing is chips were never a problem, I was always a steak and potatoes girl.
