A fascinating tool for exploring how, where and when diets evolve. Foodwise, what unites Cameroon, Nigeria and Grenada? How about Cape Verde, Colombia and Peru? As of today, you can visit a website to find out. The site is the brainchild of Colin Khoury and his colleagues, and is intended to make it easier to see the trends hidden within 50 years of annual food data from more than 150 countries. If that rings a bell, it may be because you heard the episode around three years ago, in which Khoury and I talked about the massive paper he and his colleagues had published on the global standard diet. Back then, the researchers found it easy enough to explain the overall global trends that emerged from the data, but more detailed questions – about particular crops, or countries, or food groups – were much more difficult to answer. The answer to that one? An interactive website.
While this seems a short and simple episode with some engaging conversation, it’s the podcast equivalent of the floating duck–things appear smooth and calm on the surface, but the duck is paddling like the devil underneath the surface. The Changing Global Diet website is truly spectacular and portends to have me losing a day’s worth of work or more over the next few days.
I’d be curious to see what some of the data overlays between and among some of these projects looked like and what connections they might show. I suspect that some of the food diversity questions may play into the economic complexities that countries exhibit as well.
If there were longer term data over the past 10,000+ years to make this a big history and food related thing, that would be phenomenal too, though I suspect that there just isn’t enough data to make a longer time line truly useful.

The Guadalupe River that flows through Texas used to be known as The River of Nuts, a fact that Wikipedia does not confirm. The nut in question is the pecan, Carya illinoinensis, and the pecan tree is the state tree of Texas. The groves of wild pecans that lined the rivers of Texas are, however, threatened by the very popularity of the nuts they bear, and in particular by the fickle global nut market. The Chinese, you see, have gone nuts for pecans, increasing their purchase of American pecans from 3–4% in 2006 to 30–40% today. And if they abandon the pecan as quickly as they took it up, the wild pecan groves might be abandoned too. All this, and much more, I learned from James McWilliams, professor of history at Texas State University. His new book is one of those delights that looks at the global sweep of human endeavour through a little lens, in this case the pecan.
Why it was the Chinese, rather than the French, the English or some other country, that chose to absorb the pecan surplus, I guess we’ll never know. McWilliams told me that Chinese people he spoke to believe the nuts prolong life; irrational as that may seem, no American grower is going to say they don’t. And while the high prices are good news for growers, they’re not so good for people who want pecan-containing industrial food.
