Good news for fellow caffeine addicts! A new (2026) study published in the Journal of the American Medical Association (JAMA) found an association between drinking caffeinated coffee and caffeinated tea with a reduction in dementia risk.
The study by Zhang et al., which followed over 131,000 people for up to 43 years, found that drinking caffeinated coffee was associated with an up to 18% reduction in dementia risk, with consumption of caffeinated tea being associated with similar cognitive benefits. According to the study, "the most pronounced associated differences were observed with intake of approximately 2 to 3 cups per day of caffeinated coffee or 1 to 2 cups per day of tea."
