Efforts to have men eat chives for digestion (12)
I believe the answer is:
achievements
'efforts' is the definition.
'men eat chives for digestion' is the wordplay.
'for digestion' indicates an anagram.
'men'+'eat'+'chives'='meneatchives'
'meneatchives' is an anagram of 'ACHIEVEMENTS'.
'to have' acts as a link.
(Other definitions for achievements that I've seen before include "Even a chemist (anag.)" , "they're accomplished" , "Accomplishments" .)
