Do you by chance trying to modify the Food Status two times with the the “Use Item Add Character Status Values” Array? Regarding my expirience every Status-Value can only modified once with this array. If you have one two times, then the first one will always win and the second one will never be executed.
Another Idea. Have you ticked “Force Use Item Add Character Stats on Dinos”? I would guess you have, because if not nothing you added inside the Array will affect any Dino.
But if not, maybe the Values changed by your Item are implied from the Child you created it from?
