Where the numbers come from

Drink sizes: a US standard drink is 14 g of pure alcohol (NIAAA), a Canadian one 13.45 g (CCSA), a UK unit 8 g (NHS), and Australia and the WHO count in 10 g drinks. Grams are worked out as volume × strength × 0.789, the density of alcohol. Calories are typical for each serving (USDA FoodData Central); alcohol itself has 7 kcal per gram, and mixers add more.

Advice: Canada's Guidance on Alcohol and Health (2023) calls 2 or fewer drinks a week low risk, 3 to 6 moderate and 7 or more increasingly high, with no more than 2 on any occasion. The UK Chief Medical Officers (2016) say it is safest not to drink more than 14 units a week on a regular basis, spread over 3 or more days. Australia's NHMRC (2020): no more than 10 standard drinks a week and 4 on any one day. The US Dietary Guidelines 2025-2030 dropped the old one-a-day and two-a-day numbers and say only to consume less. The federal Alcohol Intake and Health Study (Journal of Studies on Alcohol and Drugs, 2026) found lifetime alcohol deaths pass 1 in 100 above 8.5 drinks a week. The cancer risk table is from the US Surgeon General's 2025 advisory on alcohol and cancer.

Why the advice changed and what the studies disagree on: Alcohol after the new guidance: is a drink a day still fine? What Canada, the US, the UK and WHO now say.

General information, not medical advice. If you are pregnant or trying to be, have liver disease, take medicines that interact with alcohol, or find it hard to stop once you start, the advice is not to drink; talk to your doctor about what is right for you.
