Consuming, for example, about a can (6)
I believe the answer is:
eating
'consuming' is the definition.
(eating is a kind of consuming)
'example about a can' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'about' is an insertion indicator.
'can' becomes 'tin' (both are metal containers).
'a'+'tin'='atin'
'eg' enclosing 'atin' is 'EATING'.
'for' is the link.
(Other definitions for eating that I've seen before include "Out to dinner?" , "Taking in solid food" , "Putting away" , "Ingestion" , "at breakfast?" .)
