The large study on nearly 14,000 elderly participants revealed an association between wine consumption and a reduction in 'all-cause mortality'.
The researchers, Maria M. Corrada, Annlia Paganini-Hill and Claudia H. Kawas, investigated the potential link between intake of antioxidant vitamins, calcium, and certain beverages and all-cause mortality.
Participants were elderly adults from the Leisure World Cohort Study, a population-based prospective investigation in a California retirement community. Between 1981 and 1985, 13,979 subjects completed a baseline mailed survey about lifestyle and medical history.
After adjusting for age, gender, smoking, exercise, BMI, and medical histories, alcohol intake (about a drink a day) and the highest category of caffeinated coffee drinking (1 cup/day) were associated with a reduction in all-cause mortality.
"Wine appeared to be the specific type of alcohol most responsible for the reduction," conclude the scientists, adding that intake of antioxidant vitamins, calcium, or tea was not associated with mortality.
The paper, "Intake of Antioxidant Vitamins, Calcium, Beverages and Mortality: The 90+ Study" was presented last week at the 56th meeting of the American Academy of Neurology in San Francisco.
