Coffee and Tea May Protect Against Dementia

Regular consumption of coffee and tea was associated with a lower risk for dementia and modest improvements in cognitive performance, independent of a person’s genetic predisposition, a study published in JAMA showed.

Results from two large cohorts showed that the benefits were strongest among those with a daily intake of about 2-3 cups of caffeinated coffee or 1-2 cups of tea. These associations remained consistent even when accounting for high-risk genetic factors, including APOE4 genotype and Alzheimer’s disease polygenic risk scores.
