I have heard from a number of Thais and even some foreigners that the watermelon and the lumyai have high amounts of chemicals on them to keep away the bugs from eating them. However, they of course get through the skin and into the flesh of the fruits.
Lumyai is one of my favorite fruits of all-time, but now I don’t eat more than about a kilogram a season.
Another fruit that is dangerous because of the calories – is Durian. It has actually killed people that ate too much. More research is needed into why, but just hearing it from a number of people has stopped me from eating it excessively.
