There’s a common notion that, like the proverbial apple, a glass of wine a day could keep the doctor away. But is this theory based on fact or myth – and what does the science say?
Unfortunately, there’s no straightforward answer. Some studies have found that low to moderate drinking (one or two standard drinks per day) is associated with a decreased risk of heart disease. However, a recent study that looked at the alcohol consumption of 600,000 people found that more than five drinks per week could reduce lifespans by up to two years. That same study found that moderate alcohol consumption has no overall health benefits, contradicting the idea it may lower the risk of heart attack.
Clearly, more research is required when it comes to the benefits and consequences of moderate drinking. For now, let’s look at what we know about studies and what we know about alcohol consumption.
KEYS TO “HEALTHY” DRINKING
Consensus within the Canadian medical community is that alcohol consumption should follow the Health Canada guidelines. This means a maximum of 10 drinks per week for women, with no more than two drinks per day; and no more than 15 drinks per week for men, with a maximum of three drinks per day. Health Canada considers one drink to be 12 ounces (341ml) of beer, 5 ounces (142 ml) of wine or 1.5 ounces (43 ml) of spirits. I would also recommend incorporating days of no alcohol consumption.
There’s still a lot that we don’t know about low to moderate drinking. It’s important to cut back if you’re trending into bingeing territory, but there’s likely no reason to stop drinking entirely if you follow these guidelines. So go ahead and enjoy that glass of rose or cold beer after your hike – just remember, in moderation!
