Accurate account of Japanese eating habits.

Re diet: putting aside that alcohol-per-capita consumption here in Japan is less than the OECD average [1], and also how the article is actually about how the introduction of meat into the Japanese diet has caused a decrease in strokes (i.e. this is probably off-topic); it is true that if you are eating out cheaply, you'll likely find lots of rice and meat stuff like gyuudon (beef on rice), katsudon (breaded meat on rice) and what not. But a normal Japanese meal generally has a pretty good mix of stuff - some fermented side dishes (tsukemono), some veggies, miso soup, some rice or noodles, some fish, maybe some meat. Perhaps my wife is an outlier, but every meal she's cooked for our household has had at least 3 dishes of different categories as a part of it, and my impression from seeing other households and just looking at a typical bento box, is that that's a pretty normal expectation for any healthy meal. Someone else pointed me to this Youtube video on the topic on a different thread, and I'd say it's pretty accurate [2]. When I go to drinking bars, izakayas, with Japanese people they usually tend to do the same and order a variety of small dishes too - it's not common to just get fried chicken (karaage), but rather people almost always also throw in salty drinking foods (otsumami), which usually include seafood, pickles and vegetables (shiokara, takowasa, various tsukemono and so on). Even then, if someone orders sweets or something, they tend to be a lot less unhealthy
