Cut down on salt and anything sweet (6)
I believe the answer is:
nectar
'anything sweet' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'cut down on salt' is the wordplay.
'cut' means to remove the last letter.
'down' becomes 'neck' (both can mean to finish a drink).
'on salt' becomes 'tar' (both can informally mean a sailor. I am not sure about the 'on' bit.).
'neck' with its last letter removed is 'nec'.
'nec'+'tar'='NECTAR'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for nectar that I've seen before include "Food of gods" , "Trance (anag)" , "Sweet fluid produced by flowers" , "Sweet liquid secretion to attract pollinators" , "Drink of the gods consumed in trance" .)
