Re: Is Sugar apple= cherimoya?
Sugar apple is a different Annona species.
Cherimoya has been linked to Atypical Parkinson's disease, although you would need to eat on average 4 fruits every month of the year. I won't eat them, and I don't recommend them to anyone. However, I would acknowledge that Cherimoya is one of the best tasting tropical fruits in the world.
