New Study: Even Light Drinking is Deadly

We often hear that moderation is key to good health. In fact, I regularly preach this. But sometimes our definitions of “moderate” can vary, and what we think is a helpful amount of a food, beverage, supplement or form of exercise, is actually harmful. I love me a glass of wine, let me tell ya what. And right now, going into month six of pregnancy, I’ve got to confess that I miss it. So, trust me when I say that I’m just as disappointed as you may be to learn that a drink a day doesn’t in fact keep the doctor away. Read on for the latest research published earlier this month…


Before I dive into the findings, I want to say that I understand this is a niche topic finding its way onto my blog, but I think it’s important that we all stay current on relevant research. It can make a difference in our health habits and intentions.

For better or worse, it takes a while for new information to change our habits. Even when repeat studies are done it can be difficult for many of us to accept something that disproves our existing beliefs or biases. As an example of how long health information can take to impact the masses, let’s look at the history of cigarettes (which I feel parallels the history of alcohol use and research).


A Lesson from The History of Cigarette Smoking

Around the end of the 19th century, cigarette smoking became popularized. At the time, doctors were largely unfamiliar with lung cancer because it was such a rare condition for someone to have. Medical professors even often told students they would likely never see a case of lung cancer!

Around the 1940s to 1950s, cigarette manufacturers became aware that smoking had negative health consequences but, trying to protect bottom lines, worked to dispute such scientific claims. This wasn’t hard to do because the public was still trying to tease apart how many emerging cardiopulmonary issues were linked solely to cigarettes and how many were attributable to other issues of the era such as asphalt dust, air pollution, exposure to gas during WWI, and long-term effects of the 1918 influenza pandemic.



After multiple studies released undeniable evidence of the negative health effects of tobacco use, some of the American public began to buy into the idea that cigarette smoking should be avoided. Even still, with evidence on the table and a growing number of lung cancer patients, in 1960 only 1/3 of American doctors believed that cigarette smoking “should be considered a major cause of lung cancer.” In fact, 43% of all doctors were smokers themselves. Now, let’s pause for a moment to think about how this situation created a medical bias, misinformation for patients, and a preservation of a smoking culture for many more decades.

*Pause for contemplating* 

To this day, cigarettes cause 1.5-2 million deaths per year, 95% of which are believed to be entirely preventable. And we know they’re bad for us.


Alcohol Consumption is up Against an Even Greater Public Challenge for Two Reasons:

1) Alcohol has been around much longer than cigarettes. Alcohol is frequently referenced as far back as the Bible; both its abuse and its use for celebratory and spiritual occasions. Alcohol is highly cultural and prevalent throughout human history.

2) Studies on alcohol render conflicting results. For a long time, it was difficult to determine how “moderate alcohol consumption” should be defined. Even then, moderate consumption has rendered differing results; correlated with positive cardiovascular health effects (to the extent that some doctors have recommended a drink a day for certain patients) but negative impacts on cancer rates and conditions.

This is confusing stuff!

How much is okay? How much can we drink in moderation? And if we drink in moderation, is it possible to do so without drastically raising the risk of getting cancer?



The Study that Addresses Many of Our Burning Questions:

The latest study on the pros vs cons of moderate alcohol consumption was published in the journal Alcoholism: Clinical & Experimental ResearchResearchers felt compelled to analyze the effects of moderate daily drinking (defined as 1-2 alcoholic drinks) on overall mortality rates because of conflicting research showing that moderate drinking is beneficial to cardiovascular health but simultaneously raises the risk of cancer.

The researchers analyzed two data sets; one of 340,000+ people from the National Health Interview Survey (NHIS) and another of 93,000+ people from the Veterans Health Administration (VA). Both data sets were analyzed for associations between the frequency of moderate drinking (1-2 drinks at a time) and overall mortality.

*The Results*

Researchers found that moderate drinking (again, defined as 1-2 drinks) four or more times per week increases the risk of premature death by a whopping 20% across all age groups, both genders and non-smokers. These results were consistent across both data sets with very different populations (NHIS vs VA). This is fairly shocking because these findings refute what current guidelines say is healthy; 1-2 drinks/day. In other words, daily drinking cancels out the positive benefits for cardiovascular health and poses serious risks.

Moderate drinking with low levels of frequency is deemed safer than daily moderate drinking. The study discovered that moderate drinking (1-2 drinks) approximately three times a week or less is considered a safe range. With regards to overall cancer risk, abstinence from alcohol is the best bet.

Another recent study, published by The Lancet, evaluated over 700 studies on alcohol consumption from around the world and concluded that “no level of alcohol consumption improves health.” This study looked at both moderate and binge drinking.



Implications for the Future

It’s becoming more apparent that our culture’s enjoyment of alcohol is largely detrimental to our health. With these new studies emerging, doctors may suggest patients with heart health concerns have an occasional drink to help cardiovascular function but avoid daily drinking. More doctors will likely advise people to cut way down on alcohol consumption, especially patients with a personal or family history of cancer. Again, the safest consumption level is none followed by no more than three days a week consuming 1-2 alcoholic beverages at a time.

My personal stance:

I don’t plan on giving up my red wine entirely but I will definitely take this new information into consideration if I feel like I’m slipping into the habit of pouring myself a glass to unwind at the end of every day. I will keep myself in check and make sure I’m not drinking in moderation more than three days a week. Thankfully, this is fairly in line with my current alcohol habits. But, my eyes have been opened and I will be more cautious moving forward. That’s how I’m planning to use this information based on my individual health, family cancer risk factors, *and* enjoyment of a good Cabernet. But first, getting through my 9-10 months of sobriety in pregnancy.

How do you plan to adapt your drinking habits? What do you need to do?


Yours in health and wellness,
