Most of your favorite foods are probably foreign

You might think the tomato you sliced and diced for dinner last night came from Italy, but a recent study shows that most common foods did not originate in the countries we associate them withBBC reports. A team of international scientists examined the crop production and diet of 177 countries and found that no country’s diet consists solely of native foods. For example, the flavorful chilies of Thailand most likely originated in the Americas, and Ireland’s potato probably came from Peru by way of Spanish explorers. The findings highlight the importance of global interdependence of food crops, the researchers write today in the Proceedings of the Royal Society B. So it looks like we might all need each other a little more than we thought we did.
