My first CF child loved to suck on pickles, because of how salty they were. But I think we really piled the calories on with mashed potatoes and gravy with extra salt in it. Even now, all my CF kids will just dump an amazing amount of salt on their food, and it really makes things taste good to them. I honestly can't eat their left-over French Fries because of how salty they are. My kids also have always liked salty fatty meats, like bacon and sausage. Again, the salt and the fat just really seem to be a draw for my kids, which makes sense given what CF does to their bodies.
