Recently, the U.S. Surgeon General issued a new advisory linking moderate alcohol consumption to seven types of cancer. This has sparked conversations about alcohol and health, especially during “Dry January,” when many people pledge to cut back on drinking. According to a report, about a third of drinkers planned to reduce or stop consuming alcohol this month. The rise in popularity of alcohol-free drinks is also notable, with sales doubling from $10 billion to $20 billion globally between 2019 and 2023.
Experts are discussing the effects of alcohol on our health. While some studies suggest moderate drinking might lower the risk of heart disease, others highlight the cancer risk associated with even small amounts of alcohol. For instance, heavy drinking is a leading cause of preventable death, causing about 100,000 deaths annually in the U.S. However, moderate drinking—defined as one drink a day for women and two for men—might carry a lower risk for most people.
When it comes to cancer, evidence suggests that women who drink one alcoholic beverage daily have a 13% lifetime risk of developing breast cancer, compared to an 11% risk for those who drink less than once a week. This risk, however, is still minor when placed next to the significant dangers linked to heavy drinking.
Alcohol’s harmful effects stem from how our body processes it. The liver breaks down alcohol into a substance called acetaldehyde, which can damage DNA and potentially lead to cancer. Alcohol may also amplify the risks posed by other factors, such as smoking and hormonal influences, which can increase the risk of hormone-sensitive cancers.
Additionally, consuming alcohol generates free radicals—unstable molecules that can damage cells. This damage is linked to inflammation, which can also contribute to cancer growth. However, if you’re aware of the risks associated with drinking alcohol and stick to recommended guidelines, enjoying a drink occasionally is generally considered acceptable.
It’s important to approach alcohol with a clear understanding of its risks. Drinking should not be viewed as a health benefit. The idea that moderate drinking protects against heart disease is being reexamined, as many factors contribute to overall health and longevity. Moderate drinkers often lead healthier lifestyles and can have lower death rates independent of their alcohol consumption.
If you choose to drink, consider these tips to minimize risk:
- Drink with food: Eating while drinking can slow alcohol absorption and reduce peak alcohol concentration in your blood.
- Avoid binge drinking: Spreading out drinks over time is safer than consuming several in one sitting, which can increase health risks.
- Know your personal risk: Some individuals, especially those with a family history of addiction or other health issues, might want to avoid alcohol entirely.
Participating in “Dry January” can also shed light on your drinking habits and help you reevaluate your relationship with alcohol. Many find they enjoy a healthier lifestyle or discover new drinking habits that they want to maintain long-term. Overall, it’s about finding a balance that incorporates responsible drinking into a healthy life.
