The Claim
In individuals without the ApoE4 genetic variant, consumption of boiled coffee is associated with an increased risk of dementia, whereas in individuals with the ApoE4 variant, no such association is observed, indicating that genetic background modifies the relationship between coffee lipids and neurodegeneration.
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 do not carry the ApoE4 gene variant and drink boiled coffee have a higher risk of dementia compared to those who do not drink boiled coffee. People who carry the ApoE4 gene variant do not show this increased risk.
See the scientific wording
The association between boiled coffee and increased dementia risk is observed only in individuals who do not carry the ApoE4 genetic variant, while no such association exists in carriers, suggesting genetic background may modify the biological impact of coffee lipids on neurodegeneration.
Drinking boiled coffee introduces fats that raise bad cholesterol in the blood, which clogs blood vessels in the brain, leading to damage that causes memory loss and dementia — but only in people who do not have a specific gene variant that normally helps clear these fats.
What the research says
1 studyIn people without a specific gene variant (ApoE4), drinking a lot of boiled coffee was linked to a higher chance of dementia, but in people with the variant, this link didn’t show up — suggesting genes can change how coffee affects the brain.
