Good post. Fascinating.
Not entirely what I expected. Dame, I was surprised that the Mongolians have as much access to produce as they do. Their diet used to be significantly MORE meat-and-dairy based. Obviously they're buying food from the Chinese.
The Kuwaitis eating a lot of luxury imported produce, that is not traditional to the Bedouin. My mom said the food in Saudi Arabia was also luxurious, with lots of fine imported produce.
That German diet has too much meat and too much beer. I know Germans are a lot fussier about un-natural preservatives, flavors, and food colors than English-speakers but the overall balance looks wrong, and they probably get too much traditional preservative like nitrates in preserved meats. Promotes heart attacks. That killed meinen deutschen Opa (Grandpa). Germany and Japan are leaders in relatively benign high-tech preservation methods so things might be changing.
English speakers eat too much processed food! Yikes, especially that first American family, that eats way too much fast-food. I really appreciate, though, how candid both the families and the photographer were. That is really useful for thinking about diet.
Something that really stuck me was how humans can compensate quite a bit for income level without compromising food value too much. In fact the most affluent diets are unhealthy. It doesn't get bad until you're down to bags of rice like the Mali refugees. I'll hazard a guess that the refugee center gives them vitamin tablets to compensate, otherwise they'd be dead of scurvy.
Looks like fare is pretty meager for the Ecuadorians too. It is strange to think of people who live that close to the equator bundled up like that and having so little fresh produce. Obviously they are mountain people living at extremely high elevations, and apparently not trading with folks at lower altitudes to get more fresh produce. I was under the impression that in the Andes both trade and actually owning fields at different altitudes is common; these people are apparently very poor.
Price levels don't mean all that much despite globalized trade. Those Chinese families are eating VERY well. First of all some foods are subsidized in China, second, the renmenbi is obviously very undervalued.
The Indians eating fairly well too--they simply eat lower on the food chain overall, but they get some nice produce that would be expensive in many countries. The rupee also obviously undervalued. Those folks are probably in the tropical south.
