The Claim
General coffee consumption, without distinction of brewing methods, is not significantly associated with dementia risk after adjustment for lifestyle and health factors, suggesting that aggregated metrics of coffee intake may obscure differences attributable to preparation type.
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.
People who drink coffee in general, regardless of how it is brewed, show no difference in dementia risk compared to others when lifestyle and health factors are taken into account. Differences between brewing methods may not be visible when coffee intake is measured as a single total.
See the scientific wording
General coffee consumption, without distinguishing brewing methods, shows no significant association with dementia risk after adjusting for lifestyle and health factors, indicating that aggregated coffee intake metrics may mask important differences based on preparation type.
Drinking coffee that is boiled without a paper filter raises bad cholesterol in the blood, which causes blood vessels in the brain to narrow and become damaged over time. This damage reduces blood flow to brain cells and leads to their death, increasing the chance of dementia.
What the research says
1 studyWhen scientists looked at all coffee together, they didn’t see a link to dementia—but when they separated boiled coffee from filtered coffee, they found boiled coffee might increase risk in women, while other kinds might lower it in men. So, how you brew coffee matters more than just how much you drink.
