And, yes, there is that other population that got it right. They reside in Karelia, Finland. Here, the message was not willfully garbled for profit, but was assessed carefully, and applied with fidelity. This population heeded the actual prescription of Keys and others of his day. The result? A marked increase in life expectancy, and an 80% reduction in incident cardiovascular disease.

That bears repeating: the basic message about metabolism maintenance that is seemingly so controversial now, when applied faithfully, produced a 80% reduction in heart disease rates at the level of a whole population, persisting now for decades. This is among the more stunning achievements in the history of public health.
