Dear Subscribers,
I trust this short post with an audio finds you well. Today, I’m writing about a topic close to my heart: the nuanced effects of alcohol, or, scientifically, ethanol, on our health. This isn’t an anti-drinking message; instead, it’s an exploration of what science tells us about alcohol’s impacts, especially as moderation doesn’t look the same for everyone. I aim to provide a perspective based on decades of scientific research and personal observations—both as a cognitive scientist and as someone who’s seen alcohol’s effects up close.
In this post, I provide the key points of a recent article I published on my website and Medium titled Why No Amount of Alcohol Use Can Be Considered Entirely Safe for Health. I prepared interactive and educational audio attached to this post, which you can listen to here or download for free.
Let’s start with the basics. Alcohol’s risks extend beyond just “heavy drinking”; even small amounts can affect the liver, heart, and brain and may raise cancer risk. In fact, the World Health Organization (WHO) classifies alcohol as a Group 1 carcinogen, linking it to seven types of cancer, including liver and breast cancer. Considering these findings is essential—not to judge, but to make informed choices. WHO’s stance, along with data from medical research, underscores that no level of alcohol is entirely without risk.
I’ve seen how alcohol impacts people differently. A friend who enjoyed moderate drinking found himself struggling with addiction, which derailed his dreams and caused him years of hardship. His story revealed the potential dangers in our society’s normalization of “moderation.” It’s not always a safe zone; for some, it’s the start of a slippery slope. Meanwhile, studies on alcohol’s “health benefits,” like resveratrol in wine, often downplay the much larger volume of research pointing to its toxic effects on cells and organs.
Five Critical Health Risks of Alcohol
Cancer: Alcohol’s association with several cancers is well-documented and acknowledged by agencies like the WHO. Even light drinking raises cancer risks, including breast and liver cancers.
Heart Health: While some believe in alcohol’s heart health benefits, the scientific evidence reveals that even moderate drinking can raise blood pressure and increase the risk of heart conditions.
Cognitive Decline: Ethanol affects the brain, from neurons to cognitive abilities. Chronic use can lead to mental health issues and increase the risk of dementia.
Immune Suppression: Alcohol weakens immune responses, leaving us vulnerable to infections like pneumonia. It disrupts white blood cells, which are critical to fighting infections.
Digestive Health: Alcohol irritates the gut, contributing to ulcers and malabsorption of nutrients essential for our health.
I will discuss its caloric and hormonal impact in an upcoming story about metabolic health, including insulin resistance, diabetes, and obesity, which has comprehensive implications. The mental health impact, especially from an addiction point of view, also requires a detailed article, which I will cover soon.
Given that alcoholic beverages are man-made, future innovations could allow us to mitigate the risks associated with their consumption. As we have learned to produce alcohol, who knows what breakthroughs may lie ahead that could protect our vital organs and systems?
It is worth noting that alcohol itself is not inherently dangerous; it occurs naturally in small amounts in certain foods, such as fruits. However, humans have learned to synthesize it in large quantities, turning it into a beverage with natural or artificial flavors some of us consume as casually as water.
My message isn’t about passing judgment on anyone’s choices. Instead, I hope it sheds light on the realities of alcohol’s impact on our bodies—knowledge that helps us navigate our health journeys. Whether moderation works for you or not, it’s important to consider the broader context beyond social norms.
I encourage open discussion—please feel free to share your thoughts and experiences. Let’s continue this conversation with empathy, staying informed and balanced.
Wishing you health and happiness 🙏
