Absorb (food) (6)
I believe the answer is:
digest
'absorb food' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for digest that I've seen before include "Periodical that summarises the news" , "Break down (food)" , "Periodical that summarizes the news" , "Long walk, itinerant person" , "Collection of shortened versions" .)
