A July 2023 study by the National University of Singapore said,
“Our results showed that drinking coffee, black tea or green tea at midlife were independently associated with significantly reduced likelihood of physical frailty at late life. Participants who drank four or more cups of coffee per day had significantly reduced odds of physical frailty at late life, compared to participants who did not drink coffee daily. Participants who drank black tea, green tea daily also had significantly reduced odds of physical frailty, compared to non-tea drinkers.”
“Coffee and tea are mainstay beverages in many societies around the world, including Singapore. Our studies show that consumption of these caffeinated drinks at midlife may be associated with a reduced likelihood of physical frailty in late life. However, further studies are still needed to confirm these longitudinal associations, and to investigate if these effects on physical frailty are mediated by caffeine or other chemical compounds.”
