It would be interesting to see a graph comparing the decrease in the consumption of natural fat during low-fat push of the 90’s with the rise in Type 2 Diabetes. More and more carbs were consumed, mostly refined. Instead of the nutritious fat that comes from meat, butter and eggs, people ate more and more partially hydrogenated oils in cookies, etc.
In looking at the chart, Japan is the longest-lived, followed by some other Asian countries. This is puzzling since the Japanese and others eat a lot of white rice, thus a high-carb diet. They eat a lot fish, too, though, so maybe that offsets the rice.
On the other hand, I have spoken to Vietnamese and people from Muslim countries who have a very high rate of Type 2 diabetes. They told me it is because of high rice and pasta consumption.
Why would some Asian countries with lots of white rice live a long time and other Asian countries develop diabetes?
