Here in Mexico Exotic fruit is in because its healing properties,it's natural, and although some of them have a disgusting smell, they taste delicious!
This is the case of a Durian. Another exotic and cheap fruit is one called Noni which is very popular in markets. Even merchants sell Noni caps and give you samples of it.
Exotic fruit was considered dangerous because people lack of information and didn't feel like exposing their health. Nowadays, you can find it easily, especially, in the traditional market of naturist stores.
Particularly, I prefer natural and exotic fruit than those things of microbiotic.
My favorite one is Pitaya, also called the Red Dragon ;)
