To the Editor: In their study of habitual caffeine intake and the risk of hypertension, Dr Winkelmayer and colleagues1 analyzed data from a large population-based cohort study in US nurses. Total caffeine intake was associated with risk of hypertension in this study, but no relationship with consumption of caffeinated coffee was observed. Cola and other caffeinated soft drinks, however, appeared to increase blood pressure.
