I too am backpacking and would be interested in what is said.
But to be honest two months is a short period of your life and I wouldnt worry about it. You travel to try new things and I will be taking this to the extreme (eating insect dishes etc!)
Just eat real food where possible. We all know what real food means. I may take some omega three supp. but when you relocate it can take months to adjust to your new food supply, theres no point fretting about it just enjoy your travels. Like me
