For starters, look at the middle row with three graphs. See how the center and right-hand graph have black and white bars that follow a similar distribution? That means the intake of those foods wasn’t massively different between the native Japanese and the Hawaii-dwelling Japanese. Now look at the labels on those particular graphs: Meat and Ham, Bacon, Sausage. As you can see, the majority of both native and Hawaii-dwelling Japanese were eating regular meat two to four times per week, and ate processed meats less than twice per week. Out of all the foods documented, the ones with the smallest difference of intake between native and Hawaiian Japanese populations were flesh foods.
How ’bout that.
Now look at the bottom left graph that says Fish. The white bars, representing the native Japanese, show that about 40% of Japan’s population ate fish at least seven times per week—compared to only about 8% of Japanese living in Hawaii, who were apparently unaware of their islands’ marine bounty. In sharp contrast to their native diet, over half of the Hawaiian Japanese ate fish a maximum of once per week.
