Several investigators have observed that a moderate intake of alcohol can have a positive effect on health (lowering the risk of cardiovascular disease, gall-stones, etc.).

Abstract

Several investigators have observed that a moderate intake of alcohol can have a positive effect on health (lowering the risk of cardiovascular disease, gall-stones, etc.). Our objective was to investigate how some blood constituents are affected by the consumption of different levels of alcohol. Erythrocyte phospholipids and fatty acids composition and plasma fat-soluble vitamins were determined in 28 volunteers who were divided into three groups according to their alcohol intake: non-drinkers, moderate drinkers--consumption of 20-60 g/day, and heavy drinkers--more than 60 g/day. A relation was seen between alcohol consumption and vitamin status; furthermore alpha-tocopherol and beta-carotene were significantly lower in heavy drinkers. The erythrocyte phospholipid compositions of the non- and moderate drinkers showed no significant differences whereas a definite relation was noted when the alcohol intake was higher than 60 g/day. In conclusion it is possible to say that a moderate alcohol intake does not have any significant effect on the phospholipid and fatty acid composition; only the vitamin status is significantly influenced, but to confirm our results it is essential to evaluate other variables involved in this problem such as the lifestyle, physical activity and the eating habits of the subjects tested.
