The Claim
Reducing daily alcohol consumption from approximately 350 ml to 70 ml of ethanol per week in normotensive men causes a clinically significant reduction in systolic blood pressure by 3.1 mm Hg, independent of weight loss, demonstrating a direct pressor effect of alcohol in this population.
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.
In normotensive men, reducing alcohol intake from about 350 ml to 70 ml of ethanol per week lowers systolic blood pressure by 3.1 mm Hg without changes in body weight, indicating alcohol directly raises blood pressure.
See the scientific wording
Reducing daily alcohol consumption from approximately 350 ml to 70 ml of ethanol per week in normotensive men leads to a clinically significant reduction in systolic blood pressure by 3.1 mm Hg, independent of weight loss, indicating a direct pressor effect of alcohol in this population.
When alcohol is consumed, it triggers the nervous system to release more of a chemical that tightens blood vessels. This makes it harder for blood to flow, which raises the pressure inside the arteries. When alcohol intake is reduced, this tightening effect decreases, and blood pressure drops.
What the research says
1 studyWhen men who drink alcohol regularly cut their intake by 80%, their blood pressure went down—even after accounting for losing a little weight. When they started drinking normally again, their blood pressure went back up. This shows alcohol itself raises blood pressure.
