Drinking 2–3 cups of coffee a day linked to dramatically lower dementia risk

Drinking two to three cups of caffeinated coffee each day may lower the risk of dementia, according to a long-term study of U.S. adults. Researchers discovered that participants who consumed higher amounts of caffeinated coffee had dementia rates significantly lower than those who rarely or never drank it. The strongest associations appeared among people who drank two to three cups of caffeinated coffee daily.

Tea consumption was also linked to better cognitive outcomes, though the beneficial amount was slightly lower. The study showed that decaffeinated coffee did not have the same benefits, indicating that caffeine might be the key factor. While the findings suggest an association between coffee consumption and lower dementia risk, they do not prove that coffee directly prevents the condition.
