I am sure MH will answer your question. But being born and brought up myself in India, I can tell you that all fruits that you will get in India are better than what we get here in the US! Not as many pesticides and preservatives are used on fruits in India.. except maybe on Mangoes and bananas since they pluck them raw and then use Ethylene to artificially ripen them - I hate that they do so, but what can one do? Having eaten fruits in India and the US, I can attest to the fact that all fruits and veggies grown in India taste better! The mangoes, even if ripened by ethylene, taste the best in the world. And you certainly wont find any wax on the fruits like we find here. So, I would say dont be afraid to try the OJ fast on those lovely Nagpur oranges!! You couldnt go wrong! Good luck!
