The global study by the Institute for Health Metrics and Evaluation was published in health journal Lancet and looked at alcohol risk by global geographical region, age, sex and year, analysing 30 years of data on people aged between 15 and 95 across 204 countries.
The research found that while small quantities of alcohol was beneficial for people over 40, no amount of alcohol was good for younger people.
Here's what you need to know about the study and the impact of alcohol on health.
Is alcohol good for health?
No amount of alcohol is healthy if you're younger than 40, according to a new study. This is mostly due to alcohol-related deaths by auto accidents, injury and homicide.
However, if you're 40 or older and without any underlying health conditions, the study found that small amounts of alcohol may reduce your risk of cardiovascular disease, stroke and diabetes.
Senior author Emmanuela Gakidou, professor of health metrics sciences at the Institute for Health Metrics and Evaluation, explained: "Those diseases just happen to be major causes of death in a good chunk of the world. So when you look at the cumulative health impact, particularly among older adults, it shows that a small amount is actually better for you than no drinking.
"For all other causes, it's harmful at all levels of consumption."
Despite benefits against a few diseases, alcohol consumption doesn't help many other illnesses like tuberculosis, hypertension, atrial fibrillation, liver disease, epilepsy, pancreatitis and many types of cancer.
How much alcohol is healthy for you?
The study analysed the risk of alcohol consumption on 22 health outcomes, including injuries, cardiovascular diseases and cancers, using the 2020 Global Burden of Disease data.
Using these figures, researchers estimated how much alcohol a person can drink before they take on excess health risks. They found that the level of alcohol that could be consumed without increased risk to health went up throughout our lifetimes.
The research deemed a standard drink as a 100ml glass of red wine or a 375ml can or bottle of 3.5% beer.
For men aged 15-39, the recommended amount of alcohol before "risking health loss" was 0.136 of a standard drink a day. For women the same age it was 0.273 of a standard drink.
Meanwhile, for those aged 40-64, the safe alcohol consumption levels were higher, ranging from around half a standard drink a day to nearly two drinks.
Among those aged 65 or older, the safe level was even higher at a little more than three standard drinks a day.
Though the level of safe alcohol consumption increased with age, the study also noted that health risks increased with each drink consumed.
