In a January 2020 study by the Chinese Academy of Medical Sciences it was said that,
“Habitual tea consumption is associated with lower risks of cardiovascular disease and all-cause death"
"The favourable health effects are the most robust for green tea and for long-term habitual tea drinkers."
"The protective effects of tea were most pronounced among the consistent habitual tea drinking group. Mechanism studies have suggested that the main bioactive compounds in tea, namely polyphenols, are not stored in the body long-term. Thus, frequent tea intake over an extended period may be necessary for the cardioprotective effect."
