I always thought it was a bad idea as the only sane approach from a player perspective it to automate it away:
Have your client trawl whatever item he sees and database them, do some 'big data' on it to find the sweet spots (aka. developer oversights), feast that stuff and drink to desatinate as if there's no tomorrow (with a pinch of salt, or a wagonload in case it's available). Rinse and repeat with every fix that is thrown at it.
It would make a little sense in case food would debuff itself, or at least buff other areas - but as it is it feels pointless and like a waste of electrons.
