Drinking 2 to 3 cups of coffee a day is associated with a lower risk of dementia, study with 131,000 people shows
Regularly consuming moderate amounts of caffeinated coffee is linked to a reduced risk of developing dementia, according to a large-scale study.
A recent study published in the Journal of the American Medical Association (JAMA) has found a significant association between moderate caffeinated coffee consumption and a lower risk of dementia. The research analyzed extensive data from 131,821 participants in the United States who were followed for up to 43 years, including both men and women from the Nurses’ Health Study and the Health Professionals Follow-up Study. Importantly, individuals with a prior history of cancer, Parkinson’s disease, or dementia were excluded from the study to ensure the integrity of the findings.
Over the years of follow-up, 11,033 participants were diagnosed with dementia. The comparisons drawn between low and high coffee consumption revealed striking differences in the rates of dementia development. Specifically, there were 330 cases of dementia per 100,000 individuals with low caffeine intake compared to only 141 cases among those who consumed high amounts of coffee, underscoring the potential protective effects of moderate coffee drinking against cognitive decline.
The implications of these findings are notable, as they not only contribute to the growing body of literature supporting the health benefits of coffee but also suggest that dietary choices could play a significant role in cognitive health as individuals age. While the study emphasizes moderation, it opens avenues for further research into the mechanisms by which caffeine may confer neuroprotective benefits and potentially influence lifestyle recommendations for preventing dementia.
