Moderate alcohol intake and nutritional status in nonalcoholic elderly subjects.

Three hundred and seventy-three female and 213 male nonalcoholic subjects, aged 60-100 y, who had participated in a nutritional status survey of elderly people in the Boston area were grouped according to usual alcohol intake: 0-4, 5-14, or 15+ g/d. The age- and sex-adjusted mean intake of calories, fat, protein, carbohydrate, and 10 micronutrients and the mean levels of 14 nutrient and 22 nonnutrient biochemical indices were compared for the three categories of alcohol intake. The mean micronutrient intakes were also adjusted for total caloric intake and the mean nutrient biochemical concentrations were also adjusted for the corresponding nutrient intakes. The results suggest that caloric intake and blood concentrations of retinol, iron, ferritin, HDL cholesterol, AST, and ALT increased with increasing alcohol intake whereas folate and phosphorus intakes and blood measures of riboflavin, copper, zinc, urea nitrogen, and creatinine decreased with increasing alcohol intake.
