I swear my safe foods change every other week, but string cheese always has made the list. I guess I have more of a safe number than a safe food. I will eat things that are under 200 calories. So things like canned soup, oyster crackers, granola/protein bars. Currently my safe food list is string cheese, canned soups under 200 cals, and Bobo's brand granola bites. I had a two month period where my only safe foods were string cheese and saltines, that fucking sucked.
