It also exposed just how complex and global our food supply chains have become. But according to a new study that tracks the origin of our food products, this isn’t a recent development.

In fact, we’ve been exchanging food crops for so long that today, almost 70% of crops that form the basis of a national diet (think tomatoes in Italy, potatoes in Ireland or chili peppers in Thailand) come from another region.

The researchers visualized their results in an interactive map that allows you to see where exactly different food products come from. And some of them might surprise you.
