‘Cheers!’ ‘Salud!’ We like to raise a glass when we’re having a good time. A barbecue with friends and family, a sunny beer garden, a cosy night in on the sofa… A glass of something is all part of that, isn’t it? And let’s be honest, while we’re sipping away, we’re all too keen to ignore the warnings bubbling under. After all, a glass a day is healthy, right? So, what’s the deal? Is alcohol part of a healthy lifestyle or not? FibriCheck checks the scientific facts and serves up some refreshing advice.
Alcohol: the sparkling ‘heart’ of Western culture
There’s nothing we like better than enjoying a drink. Alcohol has been part of Western culture for centuries. Our ancestors had a good excuse. The awful (and life-threatening) quality of their drinking water made alcohol a necessity.1 For a long time, beer was the favourite beverage in many families; in the wealthier classes, it was wine that had celebrity status. This situation lasted well into the 20th century. Many of us can still remember it.
Nowadays, Europe’s breweries and distilleries enjoy international fame. Prestigious wineries produce reputable wines. We no longer have (or need) the excuse of poor drinking water. Because we enjoy life, we like to keep up our traditions around alcohol. At home, with friends, eating out, at a party, at the bar in the club house: drinks are just part of that. If you’re not drinking alcohol, you can expect to be asked if you’re feeling unwell. As if you have to justify not drinking alcohol.
A glass of (red) wine a day keeps the doctor away?
But there’s a change on the horizon. We hear more and more reports about the potentially harmful effects of alcohol. But we like to dismiss them. After all, isn’t there a general perception that a daily glass of alcohol is healthy for our hearts? Everyone knows an example. Granny who lived to a grand old age despite (or thanks to?) her daily tipple. Wrinkled Mediterraneans enjoying a glass of wine under their favourite olive tree.
In a sense, it holds a nugget of truth. For example, red wine contains antioxidants that attack harmful free radicals in your body.2 However, for this to be effective, you’d need to drink a lot more wine than would be healthy for you. When it comes to antioxidants, you’d be better off drinking tea.
What is true is that limited alcohol consumption can have a healing effect on the heart. Small quantities of alcohol (no more than 7 standard units per week for women and 14 standard units per week for men) reduce the risk of heart problems for one-third of patients.3 But the emphasis really is on small quantities.3 Because there’s evidence that even moderate levels of habitual alcohol consumption can relentlessly tip the balance in the other direction.4
So is every additional glass of alcohol really one too many?
Check: do you drink more or less than average?
In 2018, the World Health Organization (WHO) published a sobering report.5 One in twenty people worldwide dies from the consequences of excessive alcohol consumption. Strikingly, around one-fifth of these deaths are due to cardiovascular disease.
Hearing these figures, we automatically imagine heavy drinkers. But is that the case?
What does science mean by ‘excessive alcohol consumption’? Feeling a bit tipsy has little to do with it. Scientific research provides some hard figures.4 An objective criterion to measure yourself against.
- Light drinker: < 7 standard units per week
- Moderate drinker: 7 to 21 standard units per week
- Heavy drinker: > 21 standard units per week
For information: a standard unit is a regular wineglass or a half-pint with an average of 12 g alcohol.
Another striking result in the WHO report is that Europeans are top of the league when it comes to alcohol. Although consumption has fallen slightly since 2010, we are the world’s biggest drinkers. Averaging 33 g of pure alcohol per day. This is equivalent to two 150-ml glasses of wine, a 750-ml bottle of beer, or two 40-ml glasses of spirits. Averaging. This means that most of us don’t come into the ‘light drinker’ category.5
