Unless you go to a farmer's market, much of the produce you buy comes from other states or even neighboring countries.

But if you think back to where fruits, vegetables and legumes actually originated, you'll see that over 70% of the fruits and vegetables you'll find in average supermarkets were first grown in completely different geographical regions than the ones in which they're now cultivated.

Researchers from the International Center for Tropical Agriculture (CIAT) and several other international universities did a broad analysis of different regions' diets and produce, and published their results in the biology journal Proceedings of the Royal Society B in June. The researchers also placed the origins of each crop on interactive maps.

Most Americans are used to seeing apples and oranges in their local grocery store, but the fruits' origins might be surprising. Here's where six common varieties of produce were actually first grown.
