During the Korean War, for instance, pathologists doing autopsies on American soldiers killed in battle noticed that many had significant plaque buildup in their arteries, even though they were only teenagers. The Koreans killed in battle did not. This was later attributed to the fact that the American soldiers ate plenty of butter, meat, and dairy products—all rich in saturated fat—and the Korean soldiers did not. But disparities in sugar consumption could also, obviously, have explained what was seen (as, of course, could other factors as well):
I've heard this exact same anecdote cited for why we should eat less meat.
