The Claim
Caffeine intake is not clearly associated with dementia risk, as the highest category of caffeine intake is associated with a 6% lower risk (relative risk: 0.94, 95% CI: 0.70–1.25), which is not statistically significant, based on data from five cohort studies.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Drinking caffeine doesn’t seem to make you more or less likely to get dementia — people who drink the most caffeine had a tiny bit lower risk, but it’s not enough to be sure it’s real.
See the scientific wording
Caffeine intake shows no clear association with dementia risk, with the highest intake category linked to a 6% lower risk (relative risk: 0.94, 95% CI: 0.70–1.25) that is not statistically significant, based on data from 5 cohort studies.
What the research says
1 studyThis study looked at whether drinking caffeine (like from coffee or tea) affects dementia risk, and found that people who drank the most caffeine had only a tiny, not meaningful drop in risk — just like the claim said.
