The Claim
Dark roast coffee produces phenylindanes, which inhibit the aggregation of both beta-amyloid and tau proteins.
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.
Dark roast coffee has a special compound that might stop two harmful proteins in the brain from clumping together, which could be good for brain health.
See the scientific wording
Dark roast coffee produces phenylindanes, which inhibit the aggregation of both beta-amyloid and tau proteins.
What the research says
2 studiesStudy: Phenylindanes in Brewed Coffee Inhibit Amyloid-Beta and Tau Aggregation
Scientists found that dark roast coffee contains a special compound called phenylindane that stops two harmful proteins in the brain from clumping together—clumps that are linked to Alzheimer’s. So yes, dark roast coffee does produce this protective compound.
Study: Phenylindanes in Brewed Coffee Inhibit Amyloid-Beta and Tau Aggregation
Scientists found that dark roast coffee contains a special compound called phenylindane that stops two harmful proteins in the brain from clumping together—something linked to Alzheimer’s. This matches exactly what the claim says.
