Fried food is healthier? That's about right (7)
I believe the answer is:
fritter
'fried food' is the definition.
'healthier? that's about right' is the wordplay.
'healthier?' becomes 'fitter' ('fit' can be a synonym of 'healthy').
'that's about' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'fitter' going around 'r' is 'FRITTER'.
'is' is the link.
(Other definitions for fritter that I've seen before include "Piece of meat, etc., coated in batter and fried" , "bit of batter" , "Deep fried item" , "Squander - fried dish" , "Item cooked in batter" .)
