Hereafter, for brevity, define 'regular' to mean NON-organic fruits. The collective noun 'exotic fruits' refers to fruits excluded or neglected, in lists advising which to buy organic or not (eg Environmental Working Group's List of the 'Dirty Dozen and Clean Fifteen', Washington Post, goodhousekeeping.com, WebMD).
Should only organic 'exotic fruits' be bought? If organic variants are not available, should I just skip the regular?
For example, my local supermarkets sell only regular dragonfruit, guava, mango, and pineapple. However, these exotic fruits originate from countries with more dubious environmental or safety standards, or without any norms or oversight whatsoever.
