Consume, as food (6)
I believe the answer is:
ingest
'consume as food' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ingest that I've seen before include "Absorb, assimilate" , "Absorb - signet (anag)" , "take in, eat" , "How to take courses" , "Take nourishment into the body" .)
