Moderate Coffee Consumption Linked to Reduced Dementia Risk in Long-Term Study

Regular consumption of moderate amounts of coffee may significantly reduce the risk of developing Dementia, according to findings from a large, long-term cohort study involving over 130,000 participants. The research tracked American nurses and healthcare professionals for up to 43 years, identifying more than 11,000 cases of dementia over the study period.

The results indicate that individuals who consumed approximately 250–300 mg of caffeine daily, equivalent to two to three cups of coffee, experienced up to a 35% lower risk of dementia compared to those with minimal caffeine intake. This protective association was most pronounced in individuals aged 75 years and younger. Notably, higher caffeine consumption did not confer additional benefits, suggesting a threshold effect beyond which no further risk reduction is observed.

Participants with higher coffee intake tended to be younger but also exhibited lifestyle factors such as increased alcohol consumption, smoking, and higher caloric intake, all of which are independently associated with elevated dementia risk. These confounding variables highlight the complexity of isolating caffeine’s specific effects.

The findings contribute to growing evidence that moderate caffeine intake may influence neurodegenerative processes, potentially through mechanisms involving neuroprotection, inflammation reduction, or improved vascular function, supporting the role of dietary habits in long-term cognitive health and dementia prevention strategies.
