With World Food Day approaching on the 16th, I started thinking — not about world hunger, but rather about how cultures approach food so differently.

Globalization has brought a lot of changes, especially in the world of food: pineapples in the dead of a Michigan winter, Belgian chocolates in Goa, peanut butter in sub-Saharan Africa. And that's just on the surface; I won't even get into the deeper economic impact of the global food trade.

But there are still some cultures that have maintained a strong mono-culinary tradition, partly because of geographic isolation, but in part of the connections it has with their history and culture.

Way, way up north, in the deep Arctic territory of Nunavut, Canada, and parts of Greenland, for example, the Inuit people still eat caribou, seal, walrus, and whale — the very animals they used to hunt in the backcountry, but don't anymore, as much of the Arctic's wildlife population recedes along with the permafrost, and modernization pushes activities like hunting into obscurity.

Watch this short video for more on how the Inuit have maintained their culinary traditions while also introducing new foods, like greenhouse-grown vegetables, into their diet.
