Moderate or small amounts of alcohol consumption provide health benefits
the verdict
CONTESTED
the evidence cuts both ways
confidence 20/100
The health benefits of moderate alcohol consumption remain heavily contested; while many observational studies suggest a J-shaped protective effect for cardiovascular outcomes, newer Mendelian randomization studies and recent meta-analyses argue these benefits are confounded and that alcohol intake linearly increases mortality and disease risks.
