Alcohol is damaging to health, increasing the risk of:

  • Stroke
  • High blood pressure
  • Heart disease
  • Liver disease
  • Certain cancers

Alcohol can have a negative impact on our mood, sleep and energy levels, and can also lead to other health risks like poor judgement, accidents and injuries.

Drinking in moderation?

Any amount of alcohol increases your risk of developing cancer. The more you drink and the more often you drink, the greater your risk. If you choose to drink, stick to the following guidelines:

  • No more than 10 standard drinks per week (to reduce your long-term health risks)
  • No more than 4 standard drinks in a session (to reduce your risk of immediate injury)
  • Have some alcohol-free days each week

Not drinking is the safest option for people under 18 and women who are pregnant, planning to get pregnant or breastfeeding. 

One standard drink is:

A standard drink contains 10 g of alcohol. A standard drink can be quite different to the amount you actually have in your glass. For example, a glass of wine at a restaurant or a can of fancy beer is often 1.5 - 2 standard drinks. Learn how many standard drinks are in your usual pour with this great online tool from Alcohol.

Alcohol and weight gain

Alcoholic drinks contain a lot of kilojoules and have no nutritional benefits. Over time, drinking alcohol can contribute to weight gain and obesity, which further increases the risk of heart disease, type 2 diabetes and some cancers.

It’s the alcohol itself that contains most of the kilojoules, not the sugar or other carbohydrates as is often assumed. To drink fewer kilojoules, go for a low-alcohol drink rather than a low-carb one.

Drinking water at a picnic

Drinking can also lead to non-hungry snacking (often on junk foods), junk food “hangover cures” (they don’t work!) and less motivation to get out and exercise. Over time, this pattern can lead to weight gain. Cutting down or avoiding alcohol will help you avoid weight gain and improve your wellbeing.
