Diet, alcohol and coronary heart disease in men

It is well known that there is a significant positive correlation between consumption of saturated fat and cholesterol and international mortality from coronary heart disease (CHD). It is less well appreciated that there is a strong negative correlation between alcohol consumption and CHD, as might be expected from the effect of alcohol on high density lipoprotein levels. Neither of the simple correlations, however, account for CHD in many countries. We examined dietary and alcohol consumption data from 18 countries. The simple correlations with CHD are as follows: saturated fat, r = 0.71; polyunsaturated fat, r = -0.34; total alcohol consumption, r = -0.58. A multiple-regression equation incorporating the dietary and alcohol data, however, yields an r of 0.92.
