Cross-Cultural Leptin Collection

 A couple of months ago I tangled with Dr. Rosedale, a prominent low-carb advocate who was talking about how his diet is better than the Kitavan diet at improving markers of longevity, like lowering leptin levels. It's kind of hard to refute that since there is no study utilizing the Kitavan diet in non-Kitavans and seeing how it improves leptin levels that I know of, but it made me curious to see some cross-cultural data on Leptin. I collected an assortment of things, just for fun (let me know in the comments if you have any interesting data I should add):

The China Joke

While I was gone, apparently The China Study received some belated smackdown. I've personally never paid much attention to that book. I took several advanced statistics classes for my degree and an epidemiology class. If I wanted to base my diet on that flawed methodology, I might be more interested. But you can hash and rehash data and it won't change the fact that epidemiology (like my own science, economics) has been responsible for crap conclusions that have not bared out in the real world.
