The Claim
A dose of 494 mg of cocoa flavanols does not produce significant changes in cerebral perfusion when administered in the absence of a flavanol-rich stimulus, as demonstrated by the absence of effect in a control condition matched for calories, caffeine, theobromine, taste, and appearance.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
Eating a specific amount of cocoa flavanols doesn’t change blood flow in the brain unless you’re also consuming other flavanol-rich foods — even if the chocolate tastes and looks the same and has the same calories and stimulants.
See the scientific wording
Cocoa flavanols at a dose of 494 mg do not produce significant changes in cerebral perfusion in the absence of a flavanol-rich stimulus, as confirmed by the lack of effect in the low-flavanol control condition matched for calories, caffeine, theobromine, taste, and appearance.
What the research says
1 studyThe study gave people a cocoa drink with lots of flavanols and found it increased blood flow to the brain — but the claim says it shouldn’t. So the study proves the claim wrong.
