Alcohol consumption and nutrient intake in middle-aged Scottish men.

The relation between alcohol consumption and dietary intake was examined in 164 middle-aged Scottish men taking part in a study of risk factors for coronary heart disease (CHD). A 7-d weighed dietary record was used to assess alcohol and nutrient intake. The mean daily intake of alcohol was 26 g (SD 31 g). Energy derived from alcohol tended to replace energy derived from other nutrients and increasing intake of alcohol was associated with a decrease in the amounts of carbohydrate, total fat, and saturated and monounsaturated fatty acids in the diet. Those with a low alcohol intake (0.1-9 g alcohol/d) had a higher intake of total fiber, cereal fiber, polyunsaturated fatty acids, and linoleic acid and a smaller proportion smoked cigarettes. The differences are small but may contribute to the lower mortality from CHD reported by other studies in those with a low alcohol intake.
