Health ought not to be taken wholly for granted (8)
I believe the answer is:
although
'granted' is the definition.
('granted' can mean 'although' or 'I admit...')
'health ought not to be taken wholly' is the wordplay.
'not to be taken wholly' says the answer is hidden in the clue (only some of the letters).
'ALTHOUGH' is hidden within 'health ought'.
'for' is the link.
(Other definitions for although that I've seen before include "However, but" , "Despite the fact that (8)" , "Apart from the fact that" , "In spite of the fact that" , "Notwithstanding" .)
