Study Suggests Coffee and Tea May Lower Dementia Risk

A new study published in JAMA hints that drinking caffeinated coffee and tea might be linked to a reduced risk of developing dementia, according to CBS News. The analysis followed over 131,000 people for several decades, finding that those who consumed more caffeinated coffee had an 18% lower risk of dementia compared to those who drank little or none.

The study, which spanned from 1986 to 2023, observed that drinking two to three cups of coffee or one to two cups of tea daily was associated with the greatest benefit. However, the study did not establish a direct cause-and-effect relationship, merely an association.

Dr. Céline Gounder, a CBS News medical contributor, advised taking the findings "with a massive grain of salt." She emphasized that while these results might seem promising, they do not prove that caffeine directly reduces dementia risk. Other factors could influence the outcomes, such as lifestyle choices related to diet and exercise.

For older adults eager to protect their cognitive health, it is important to consult with healthcare providers before making any dietary changes. Additionally, Gounder suggests that regular exercise, a balanced diet, and addressing health issues like high blood pressure are critical steps in reducing dementia risk.
