I found this article on The Economist website, but it is behind a paywall and I don't have a subscription, darn! I thought I'd link it just in case anyone was interested in it and was thinking of getting a subscription, as the topic seemed pretty interesting.
The full headline title is: "The meat spot - Japanese people may have gained longevity by balancing their diets - Japan's rate of strokes fell during a period when it began eating a bit of meat"
