don't exist, at least in OH. Some things that used to be food are now taxed because they aren't considered [as healthy as] food anymore, especially carbonated beverages. Some "juice" drinks, fruit punch, etc are taxed too, e.g. Sunny Delight, which doesn't have a lot of juice last time I checked.
If it's real juice, or milk, or coffee, or a raw ingredient (even sugar!), then it's still tax free. IINM the same distinction is used to show whether a thing can be bought with food stamps or requires Real Money.
