Alcohol consumption recommendations (Redirected from Recommended maximum intake of alcoholic beverages)

Recommendations for consumption of the drug alcohol (also known formally as ethanol) vary from recommendations to be alcohol-free to daily or weekly drinking "safe limits" or maximum intakes. Many governmental agencies and organizations have issued guidelines. These recommendations concerning maximum intake are distinct from any legal restrictions, for example countries with drunk driving laws or countries that have prohibited alcohol.

General recommendations

These guidelines apply to men, and women who are neither pregnant nor breastfeeding.

Alcohol-free recommendations

The World Health Organization published a statement in The Lancet Public Health in April 2023 that "there is no safe amount that does not affect health"'.

The 2023 Nordic Nutrition Recommendations state "Since no safe limit for alcohol consumption can be provided, the recommendation in NNR2023 is that everyone should avoid drinking alcohol."

The American Heart Association recommends that those who do not already consume alcoholic beverages should not start doing so because of the negative long-term effects of alcohol consumption.

The Canadian Centre on Substance Use and Addiction states "Not drinking has benefits, such as better health, and better sleep."

Alcohol intake recommendations by country

Some governments set the same recommendation for both sexes, while others give separate limits. The guidelines give drink amounts in a variety of formats, such as standard drinks, fluid ounces, or milliliters, but have been converted to grams of ethanol for ease of comparison.

Maximum recommended intake
Country
(or region)
Men Women Details
Australia 40 g/day, 100 g/week (Both sexes) (New guidelines were adopted in 2020.)
Austria 24 g/day 16 g/day
Canada The Canadian Centre on Substance Use and Addiction has a sliding scale of intakes.
The scale states that at 27 g or less per week, "you are likely to avoid alcohol-related consequences for yourself or others".
Czech Republic 24 g/day 16 g/day
Denmark 168 g/week 84 g/week For low risk of disease
252 g/week 168 g/week For high risk of disease.
Finland 165 g/week 110 g/week.
Germany 24 g/day 12 g/day
Hong Kong 20 g/day 10 g/day.
Ireland 170 g/week 140 g/week.
Italy 24g/day
12g/day if over 65
12g/day
Japan 29 g/day Less for women and the elderly
Netherlands The Health Council of the Netherlands recommends an alcohol consumption level of zero or no more than 10 g per day.
New Zealand 30 g/day and 150 g/week 20 g/day and 100 g/week (women) At least two alcohol-free days every week. To reduce long-term health risks
50 g 40 g On any single occasion, to reduce risk of injury.
Portugal 37 g/day 18.5 g/day
Spain 30 g/day 20 g/day Also suggests a maximum of no more than twice this on any one occasion.
Sweden The National Board of Health and Welfare defines risky consumption as 120 g per week, and 48 g or more per occasion, once per month or more often.
Alcohol intervention is offered for people who exceed these recommendations.
108 g per week, and 36 g per occasion, is not considered risky according to the new guideline.
Switzerland 30g/day 20–24g/day
United Kingdom 112 g/week 112 g/week
USA Up to 28 g/day
not to exceed 196 g/week
14 g/day
not to exceed 98 g/week

Overall, the daily limits range from 10–37 g per day for men and 10-16 g per day for women. Weekly limits range from 27–170 g/week for men and 27–140 g/week for women. The weekly limits are lower than the daily limits, meaning intake on a particular day may be higher than one-seventh of the weekly amount, but consumption on other days of the week should be lower. The limits for women are consistently lower than those for men.

Specific populations

Pregnant women

Excessive drinking in pregnancy is the cause of fetal alcohol syndrome (BE: foetal alcohol syndrome), especially in the first eight to twelve weeks of pregnancy. Therefore, pregnant women receive special advice. It is not known whether there is a safe minimum amount of alcohol consumption, although low levels of drinking are not known to be harmful. As there may be some weeks between conception and confirmation of pregnancy, most countries recommend that women trying to become pregnant should follow the guidelines for pregnant women.

  • Australia: Total abstinence during pregnancy and if planning a pregnancy
  • Canada: "Don't drink if you are pregnant or planning to become pregnant."
  • France: Total abstinence
  • Hong Kong: "Abstinence from alcohol during pregnancy is the safest choice."
  • Iceland: Advise that pregnant women abstain from alcohol during pregnancy because no safe consumption level exists.
  • Israel: Women should avoid consuming alcohol before and during pregnancy
  • The Netherlands: Abstinence
  • New Zealand: "Women who are pregnant or planning to become pregnant should avoid drinking alcohol."
  • Norway: Abstinence
  • Sweden: Abstinence.
  • UK: Abstinence during pregnancy
  • US: Total abstinence during pregnancy and while planning to become pregnant

In short, all countries listed above now recommend that women abstain from alcohol consumption if they are pregnant or likely to become pregnant.

Breastfeeding women

"Alcohol passes to the baby in small amounts in breast milk. The milk will smell different to the baby and may affect their feeding, sleeping or digestion. The best advice is to avoid drinking shortly before a baby's feed." "Alcohol inhibits a mother's let-down (the release of milk to the nipple). Studies have shown that babies take around 20% less milk if there's alcohol present, so they'll need to feed more often – although infants have been known to go on 'nursing strike', probably because of the altered taste of the milk." "There is little research evidence available about the effect that [alcohol in breast milk] has on the baby, although practitioners report that, even at relatively low levels of drinking, it may reduce the amount of milk available and cause irritability, poor feeding and sleep disturbance in the infant. Given these concerns, a prudent approach is advised."

  • Australia: Total abstinence advised
  • Hong Kong: "Avoid alcohol and alcoholic drinks."
  • Iceland: Total abstinence advised because no safe consumption level exists.
  • New Zealand: Abstinence recommended, especially in the first month of breastfeeding so that sound breastfeeding patterns can be established.
  • United Kingdom: Total abstinence advised by some, such as the Royal College of Midwives; others advise to limit alcohol to occasional use in small amounts not exceeding the recommended maximums for non-breastfeeding woman as this is known to cause harm, and that daily or binge drinking be avoided.

Minors

Countries have different recommendations concerning the administration of alcohol to minors by adults.

  • United Kingdom: Children aged under 15 should never be given alcohol, even in small quantities. Children aged 15–17 should not be given alcohol on more than one day a week – and then only under supervision from carers or parents.

Caveats

Risk factors

The recommended limits for daily or weekly consumption provided in the various countries' guidelines generally apply to the average healthy adult. However, many guidelines also set out numerous conditions under which alcohol intake should be further restricted or eliminated. They may stipulate that, among other things, people with liver, kidney, or other chronic disease, cancer risk factors, smaller body size, young or advanced age, those who have experienced issues with mental health, sleep disturbances, alcohol or drug dependency or who have a close family member who has, or who are taking medication that may interact with alcohol, or suffering or recovering from an illness or accident, are urged to consider, in consultation with their health professionals, a different level of alcohol use, including reduction or abstention.

Activities

Furthermore, the maximum amounts allowed do not apply to those involved with activities such as operating vehicles or machinery, risky sports or other activities, or those responsible for the safety of others.

Moreover, studies suggest even moderate alcohol consumption may significantly impair – neurobiologically beneficial and -demanding – exercise (possibly including the recovery and adaptation).

Daily consumption, habituation and addiction

As of 2022, moderate consumption levels of alcoholic beverages are typically defined in terms of average consumption per day. However, when drinking becomes a chronic daily activity the consumption puts individuals at an increased health risk[medical citation needed][additional citation(s) needed] as it may lead to habituation, desensitization (consumption-induced tolerance), progressively increasing average dosages and addiction.[citation needed]

According to the CDC, it would be important to focus on the amount people drink on the days that they drink. However, few studies or guidelines distinguish between or compare "moderate consumption" patterns (i.e. frequency, timing and dosage/intensity per session) of occasional drinking and daily drinking.[citation needed] One review showed that among drinkers (not limited to moderate consumption levels), daily drinking in comparison to non-daily drinking was associated with incidence of liver cirrhosis.

Harmful physiological effects

Emerging evidence suggests that "even drinking within the recommended limits may increase the overall risk of death from various causes, such as from several types of cancer". Better health outcomes among moderate drinkers that some studies reported may be due to the moderate alcohol consumption itself but they may also instead be caused by "other differences in behaviors or genetics between people who drink moderately and people who don't". According to the CDC, recent studies indicate moderate consumption may not have the protective health benefits. A systematic analysis found that "The level of alcohol consumption that minimised harm across health outcomes was zero (95% UI 0·0–0·8) standard drinks per week".

Units and standard drinks

Guidelines generally give recommended amounts measured in grams (g) of pure alcohol per day or week. Some guidelines also express alcohol intake in standard drinks or units of alcohol. The size of a standard drink varies widely among the various guidelines, from 8g to 20g, as does the recommended number of standard drinks per day or week. The standard drink size is not meant as recommendations for how much alcohol a drink should contain, but rather to give a common reference that people can use for measuring their intake, though they may or may not correspond to a typical serving size in their country.
