"Habitual Caffeine Intake and the Risk of Hypertension in Women," published in the Journal of the American Medical Association (JAMA) and authored by Wolfgang C. Winkelmayer, MD, ScD, et al., examined the association between caffeine intake and the incidence of hypertension in women.
"Caffeine acutely increases blood pressure, but the association between habitual consumption of caffeinated beverages and incident hypertension is uncertain," the authors noted.
