Fortunately you’ve gotta work pretty hard for chronic use, since it’s only available for a couple months out of the year. This is definitely a concern if they ever do develop a pawpaw industry, though.
The person you’re replying to probably assumed (as I did) that the article was about papaya, which is called pawpaw in some parts of the world. They will probably be relieved (as am I) to find out it’s about an unrelated fruit.
I've lived in a country where it was available year round, grew like a weed in gardens, and was eaten on the regular by many people I know.
