Grapples with food (5)
I believe the answer is:
apple
'food' is the definition.
(I know that apple is a type of edible fruit)
'grapples with' is the wordplay.
'with' says the answer is hidden in the clue.
'APPLE' can be found hidden inside 'grapples'.
(Other definitions for apple that I've seen before include "US computer company" , "'The ..... never falls far from the tree'" , "Fruit that keeps doctor away?" , "The - Cart (Shaw)" , "New York the Big one" .)
