Berry rich in antioxidants (and vowels) (4)

I believe the answer is:

acai

(Other definitions for acai that I've seen before include "fruit which is nutritious" , "South American food product" , "something nutritional to eat" , "South American palm tree" .)

I've seen this clue in The New York Times.
