“A drink or two a day is fine for your health, or even good for it.”
Strong confidence that the broad claim is misleading. Alcohol causally increases the risk of at least seven cancers, and risk for some cancers begins to rise around one drink a day or less. Claims of a net heart benefit at low intake remain vulnerable to confounding and do not erase the established cancer risk.
One or two drinks a day cannot be called harmless or broadly good for health. Alcohol causes several cancers, with risk for some cancers increasing at about one drink a day or less.
Risk rises with the amount consumed over time. A lower-risk pattern is not the same as a risk-free or health-promoting pattern.
Alcohol-related risk generally rises as intake rises. Lower intake means lower risk, but lower risk does not mean zero risk.
Safety note: There is no known safe amount during pregnancy. People who have been drinking heavily for a prolonged period should seek medical help before stopping suddenly because withdrawal can be life-threatening.
Talk to a healthcare professional if: Talk with a clinician if cutting back is difficult, drinking is worsening your health, or you may have withdrawal symptoms when you stop.
Do not start drinking for a supposed health benefit. If you drink, less alcohol means less alcohol-related risk.
Try alcohol-free days, smaller servings or nonalcoholic options. Get medical help for heavy use rather than stopping suddenly on your own.
