Harvard Study Links Moderate Coffee Consumption to Lower Dementia Risk
A recent study conducted by researchers from Harvard Medical School, MIT, and Mass General Brigham has found that moderate coffee consumption may be linked to a reduced risk of dementia. The study analyzed data from 131,821 participants over 43 years, collected through the Nurses’ Health Study and the Health Professionals Follow-Up Study. Participants who consumed two to three cups of coffee or one to two cups of tea daily showed an 18% lower risk of developing dementia compared to those with lower caffeine intake. The research highlights caffeine as a potential factor in cognitive health, although the benefits were not observed with decaffeinated coffee. The study emphasizes that while caffeine can be part of a dementia prevention strategy, other factors like sleep, exercise, and diet are also crucial.
