Alcohol consumption and nutrient intake in middle-aged Scottish men

Area of Science:

• Nutritional Science
• Cardiovascular Health
• Dietary Epidemiology

Background:

• Coronary heart disease (CHD) remains a significant health concern.
• Understanding dietary risk factors, including alcohol consumption, is crucial for prevention.
• Previous research suggests a link between alcohol intake and CHD mortality, but dietary interactions require further investigation.

Purpose of the Study:

• To examine the relationship between alcohol consumption and overall dietary intake in middle-aged men.
• To identify specific nutrient changes associated with varying levels of alcohol intake.
• To explore potential dietary contributors to lower coronary heart disease risk in low-alcohol consumers.

Main Methods:

• A 7-day weighed dietary record was employed to quantify alcohol and nutrient intake.
• Data were collected from 164 middle-aged Scottish men participating in a coronary heart disease risk factor study.
• Statistical associations between alcohol consumption levels and dietary components were analyzed.

Main Results:

• Mean daily alcohol intake was 26 g (SD 31 g).
• Increased alcohol consumption was associated with reduced intake of carbohydrates, total fat, and saturated/monounsaturated fatty acids.
• Low alcohol intake (0.1-9 g/day) was linked to higher fiber, polyunsaturated fatty acids, and linoleic acid intake, and lower smoking prevalence.

Conclusions:

• Alcohol energy intake appears to displace energy from other macronutrients in the diet.
• Dietary patterns associated with low alcohol consumption may offer protective benefits against coronary heart disease.
• These findings contribute to understanding the complex interplay between alcohol, diet, and cardiovascular health.
