In a scientific study, researchers with the Department of Biochemistry, Faculty of Medicine and Dentistry, University of Western Ontario, Canada, determined in 1999 that a shaken martini is demonstrably more healthy than a stirred one. Antioxidants are known to promote health, particularly by reducing the incidence of such age-related diseases as cardiovascular disease, stroke, and cataracts. Antioxidant properties are possessed by alcoholic beverages in general, including martinis; but in carefully controlled tests, the researchers determined that a shaken martini has significantly higher antioxidant properties than a stirred one. As they humorously concluded in publishing their results in the British Medical Journal, "007's profound state of health may be due, at least in part, to compliant bartenders."
