"The Seven Countries study results first appeared in a 211-page monograph published by the AHA in 1970, followed by a book from Harvard University Press. What Keys found, as he had hoped, was a strong correlation between the consumption of saturated fat and deaths from heart disease. These findings appeared conclusive and seemed to offer a definitive answer to Key's critics.
Or did they? Despite the celebrated results, there were some vexing problems with data points that failed to support his hypothesis. For instance, the Eastern Finns died of heart disease at rates more than three times higher than the Western Finns, yet their lifestyles and diets, according to Key's daat, were virtually identical. The islanders of Corfu ate even less saturated fat than did their countrymen on Crete, yet on Corfu rates of heart disease were far higher. Thus, within countries, the correlation between saturated fat and heart disease didn't hold up at all."
