Study Links Moderate Coffee Consumption to Lower Dementia Risk
A recent study published in JAMA has found that moderate consumption of coffee or tea is associated with a reduced risk of developing dementia. The research, conducted by experts from Mass General Brigham, MIT, and Harvard, analyzed data spanning 43 years from the Nurses’ Health Study and the Health Professionals Follow-Up Study. The study involved 131,821 participants and documented their consumption of coffee, tea, and decaffeinated coffee through questionnaires distributed every two to four years. The findings indicate that individuals who consumed two to three cups of coffee or one to two cups of tea daily exhibited lower subjective cognitive decline and performed better on cognitive tests. Notably, the benefits were not observed in those who drank decaffeinated coffee, suggesting caffeine as the key factor.
