Yes. Connect a lifecycle set to game start to a checker. Set the checker so it checks for the item that you want to use as food. Connect the checker to a wire repeater (check fails → ) then the wire repeater to the checker ( → Run check.) Also connect the wire repeater to a game overlay device (_ → hide overlay.) Connect the checker to a game overlay device (check passes → show overlay.) Also connect the checker to another wire repeater. Set the overlay device so it doesn’t show when the game starts. Also, set it to a button and make its text something like “eat.” Connect the overlay button to the checker (button pressed → run check) and to a health granter (assuming you want health to be granted when you eat the food.) Connect the overlay button to an item granter (button pressed → grant item) set to the food item. Make it grant -1 of that item.
I hope my block of text is the solution lol, otherwise it would be for nothing
