The Claim

In adults with elevated blood pressure (130–159/85–99 mm Hg), a reduction of 1.3 drinks per day in alcohol intake was associated with a nonsignificant reduction of 1.2 mm Hg in systolic and 0.7 mm Hg in diastolic blood pressure, indicating that the dose-response relationship between alcohol reduction and blood pressure lowering may be weaker at low-to-moderate intake changes than previously estimated.

In plain English

Among adults with high blood pressure, reducing alcohol intake by 1.3 drinks per day resulted in a very small and statistically insignificant drop in blood pressure, suggesting that small reductions in alcohol consumption may not lower blood pressure as much as previously thought.

See the scientific wording

In adults with elevated blood pressure (130–159/85–99 mm Hg), a 1.3-drink-per-day reduction in alcohol intake was associated with a nonsignificant 1.2/0.7 mm Hg reduction in systolic and diastolic blood pressure, suggesting that the dose-response relationship between alcohol reduction and BP lowering may be weaker at low-to-moderate intake changes than previously estimated.

Why this might work

When people drink less alcohol, their nervous system becomes less active in tightening blood vessels, and the blood vessels themselves relax a little, which lowers blood pressure slightly.

    When people who drink a lot cut back by about 1.3 drinks a day, their blood pressure barely drops — and the change is so small it might just be due to chance. This study shows that cutting back a little doesn’t really help lower blood pressure much.
