A Japanese study discovered that adults who consume high amounts of tea have an overall lower risk of death due to all causes, including cardiovascular disease. The researchers found that participants who consumed more than 5 cups of green tea per day experienced all-cause mortality to drop by 16 to 26 percent. Stronger effects were noted among women, where the overall death-rate fell by as much as 31% due to high green tea consumption. The study links antioxidant compounds present in green tea to life-prolonging effects.
