Food brought up from the mouth (5)
I believe the answer is:
bread
'food' is the definition.
(bread is a kind of food)
'brought up from the mouth' is the wordplay.
'brought up' becomes 'bred' (to breed is to bring up or raise).
'from the mouth' indicates a 'sounds like' (homophone) clue.
'bred' is a homophone of 'BREAD'.
(Other definitions for bread that I've seen before include "Eg, pumpernickel" , "brass" , "Lolly - basic food" , "Money (inf)" , "It may be made from meal" .)
