Healthy produce brought about some cardiac advantages (4)
I believe the answer is:
acai
'healthy' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'brought about some cardiac advantages' is the wordplay.
'brought about' says the letters should be written backwards.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'iaca' is hidden in the letters of 'cardiac advantages'.
'iaca' in reverse letter order is 'ACAI'.
'produce' acts as a link.
Can you help me to learn more?
(Other definitions for acai that I've seen before include "fruit which is nutritious" , "South American food product" , "South American palm tree" , "something nutritional to eat" .)
