A dietary survey of male volunteers, both drinkers, and nondrinkers of alcohol, on free choice diets, was conducted in Blacksburg, Virginia in the spring and summer of 1981. The survey was conducted to assess the relationship between the consumption of alcohol and the intake of selected nutrients on both a mean daily basis and on a per kilogram body weight basis. One hundred seventy-one subjects ages 18 through 56 kept food and beverage intake records for five consecutive days, including Saturday and Sunday. The food and beverage records were hand coded and processed by computer for nutrient analysis. Subjects were grouped, according to the amount of alcohol consumed, into nondrinkers, low, moderate or high drinkers. Regression and correlation analysis revealed that there was little difference among the groups of subjects in the effects of alcohol intake on intake of the traditional energy supplying nutrients, protein, fat, and carbohydrate expressed as mean daily intake and expressed on a per kilogram body weight basis. The expression of nutrient intake based on a per kilogram body weight basis made no difference in the significance of results when considering the relationship between the consumption of alcohol and calcium, iron, magnesium, phosphorus, vitamin A, thiamin, riboflavin, niacin, vitamin B6, vitamin B12, and vitamin C. The need for further investigation into the relationship between alcohol consumption and nutrient intake of social drinkers has been documented. / M.S.
