A new long-term study is drawing attention to a possible link between caffeine and brain health.
Researchers say regular consumption may be associated with a lower dementia risk, though key questions remain, reports CBS News.
Study findings
A large-scale analysis has found that people who drink caffeinated coffee or tea may be less likely to develop dementia over time.
According to CBS News, the study tracked more than 131,000 participants across several decades, with over 11,000 cases of dementia recorded.
Researchers observed that those who consumed higher amounts of caffeinated coffee had an 18% lower risk compared to those who drank little or none.
The findings also suggested reduced levels of cognitive decline among regular coffee drinkers.
Consumption levels
The results indicated that moderate intake showed the strongest association with reduced risk.
According to CBS News, drinking two to three cups of caffeinated coffee daily, or one to two cups of tea, was linked to the most noticeable differences.
“Higher caffeinated coffee intake was significantly associated with lower risk of dementia,” the researchers wrote.
Decaffeinated coffee, however, did not show the same relationship in the data.
Expert caution
Health experts have warned against interpreting the findings as proof that caffeine prevents dementia.
Dr. Céline Gounder said the results should be taken “with a massive grain of salt.”
“Studies like this drive me nuts,” she said.
According to CBS News, she stressed that the research shows a correlation rather than a direct cause-and-effect link.
Other factors
Researchers and experts noted that additional variables may influence the results.
According to CBS News, factors such as underlying health conditions or lifestyle choices could affect both caffeine consumption and dementia risk.
Some individuals may avoid caffeine due to medical issues already linked to higher dementia risk, complicating the findings.
The study authors said further research is needed to confirm the connection.
Prevention advice
Despite the findings, experts recommend focusing on established ways to reduce dementia risk.
“Now, what should you be doing to prevent dementia? Exercise, improve your diet, address weight loss,” Gounder said.
She added that monitoring hearing health may also play a role.
While the research adds to ongoing discussions, specialists emphasize that broader lifestyle habits remain the most reliable approach.
