I like to get bananas when I'l out of the country. Not pounds of them, but just a couple. I find most bananas here fairly bland (east coast, told it's totally different in other parts), but when in places like Europe they are bursting with flavor.

Southern Italy has wonderful stone fruits when they are in season, and the blood oranges from there would have been on my list too.

No matter where you are, avoiding obesity comes down to the simple fact you need to know what you are eating. You may think a meat stew is a great choice, until you find out it's in a full fat cream and wine sauce made with really fatty meat, etc. That is not country dependent, it can happen anywhere.
