The Claim
Different types of coffee consumption are associated with differing levels of dementia risk, with instant coffee associated with higher risk and ground coffee associated with lower risk, indicating that preparation method may influence neurodegenerative outcomes.
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 instant coffee have a higher risk of dementia compared to those who drink ground coffee, and this difference is linked to how the coffee is prepared.
See the scientific wording
The association between coffee consumption and dementia risk differs by coffee type, with instant coffee linked to higher risk and ground coffee linked to lower risk, suggesting that preparation method may influence biological effects on neurodegeneration.
Instant coffee contains fewer protective chemicals and more harmful ones than ground coffee, which leads to more inflammation in the brain and more buildup of toxic proteins that damage nerve cells.
What the research says
1 studyStudy: Association of coffee and genetic risk with incident dementia in middle-aged and elderly adults
This study found that people who drink a lot of instant coffee have a higher chance of getting dementia, while those who drink brewed ground coffee have a lower chance—suggesting how coffee is made might affect your brain health.
