I eat a lot of baked potatos too. Once again, I'm careful about what I put on them. No butter, no bacon, no cheese, no sour cream. That's only because that's the way most people think you should eat a baked potato. Fruit makes a great snack food.
Many fruits are excellent sources of vitamins and anti-oxidants that the body needs.
Bread has been under fire lately. Specifically white bread. There is nothing wrong with a turkey sandwich on white with some lettuce, pickles, and mustard. If you have a choice between white and whole wheat go with the one you like best. Cereals are ok too.
