Alcohol – A Healthy Choice? (How Much and Which Type)

Alcohol – A Healthy Choice? (How Much and Which Type)

Without a doubt, one of the most common questions I am asked is on whether or not alcohol consumption is a good idea. And what I have determined, after a fairly extensive review of scientific literature, is that the answer to this question is “it depends”, and you will see why.

Before we get to the relationship of alcohol to brain health, let’s first take a look at what the research tells us about the relationship between alcohol consumption and cardiovascular disease.

Alcohol and Heart Health

The dangers of heavy alcohol consumption from a health perspective have been studied and described for centuries. Heavy drinking, as it relates to heart health, is clearly associated with damage to the heart muscle, elevated blood pressure, stroke, and heart rhythm abnormalities. These health risks stand in contrast to the body of research that shows the potential health benefits of light to moderate alcohol consumption, such as a reduced risk of cardiovascular problems like coronary artery disease.

A recent review in the Journal of Internal Medicine entitled, Alcohol and Cardiovascular Disease: Where Do We Stand Today? explored the extensive literature on this subject and concluded the following:

Lighter drinking – associated with reduced risk for:

  • Coronary artery disease
  • Stroke caused by a reduction in blood supply
  • Heart failure

Heavier drinking associated with increased risk for:

  • High blood pressure
  • Coronary artery disease
  • Heart rhythm abnormalities
  • Brain bleeding type stroke

In this review, the author determined that light alcohol consumption was less than three drinks per day. That means three cocktails, glasses of wine, or glasses of beer. Heavy alcohol consumption would be more than 3 standard servings per day. In attempting to understand why low-levels of alcohol consumption might actually be heart protective, the authors described several mechanisms that may be in play.

  • Alcohol is known to raise HDL cholesterol, the “good cholesterol”.
  • Low levels of alcohol consumption help reduce the stickiness of platelets in the blood. This may well prove helpful with respect to stroke as well as coronary artery disease.
  • Low levels of alcohol consumption are associated with a reduction in risk for type II diabetes as well as the oxidation to LDL, or “bad cholesterol.”
  • And finally, the authors did report that low levels of alcohol consumption are associated with decreased psychosocial stress. And this turns out to be very important, as we now recognize that psychosocial stress is associated with a variety of health risks well beyond the heart.

So the conclusion of this comprehensive review is that low-level alcohol consumption might well be a good idea whereas higher level seems to be associated with an increased risk for some pretty worrisome problems. We see this frequently when looking at data related to the effect of our lifestyle choices on our health. For example, moderate exercise seems to be better than no exercise, light exercise, or extreme exercise. This is a characterization of the “sweet spot” as it relates to so many of our everyday lifestyle decisions. Put in a more scientific way, this is called a “U-shaped curve.” Let’s look at such a curve as it relates to coronary artery disease and alcohol consumption:

What we see in this graph is an actual reduction of risk for coronary artery disease as alcohol consumption increases, but only up to a certain point. Thereafter, higher levels of alcohol consumption are associated with an actual increase in risk, and this increase continues right along with increasing alcohol consumption. So again, we are able to identify the “sweet spot,” shown here with the blue arrow. At least in this study, it looks like around 24 g of alcohol per day would be ideal. This is the amount of alcohol in 24 oz of regular beer, 10 oz of wine, or 3.0 oz of distilled spirits.

Alcohol and Brain Health

As alcohol consumption relates to the brain, we are fortunate that there have been some recent and incredibly extensive reviews of this interesting topic. For example, a new study recently appeared in the Journal, Frontiers in Nutrition that provides a comprehensive review of the role of alcohol in brain health and disease risk and also tries to tease apart the actual type of alcohol that is consumed in terms of how it relates to these issues. This is a powerful publication that sighted 182 references.

The authors made it very clear that a similar U-shaped curve relates alcohol consumption to dementia risk, and specifically to the risk for Alzheimer’s disease as well. In fact, they revealed that “Moderate drinking of 3 to 4 glasses per day (or 250-500ml per day) of red wine was associated with a fourfold diminished risk of Alzheimer’s disease and incident dementia when compared to those who drink less, or did not drink at all.” That’s right, a fourfold diminished risk. I think it was very fair of them to continue by stating, “Despite an overall positive association of red wine consumption with better cognitive health, whether people should start drinking or increase wine consumption to avoid dementia is still debatable.”

Reduced inflammation & free radical damage

Overall, this extensive report made quite clear that there are some very positive benefits for the brain with low to moderate alcohol consumption, especially as it relates to red wine. The report goes on to provide a large number of possible mechanisms by which red wine benefits the brain, which includes over 500 different compounds that have been identified in wines. These compounds include a large number of polyphenols, which are biologically active phytonutrients that provide us important antioxidant protection and also nurture our gut microbes.

Polyphenols also work to reduce inflammation, a process that has been recognized as a pivotal player in brain degeneration.

In addition, polyphenols found in red wine have been recently identified as having iron-chelating activity, meaning they can help reduce the presence of iron that might otherwise increase free radical type damage. Free radicals are damaging molecules that can inflict injury to proteins, fats, and even our DNA.

Finally, the authors indicated that other polyphenols found in red wine might actually help reduce the formation of amyloid protein in the brain. This is the abnormal brain protein that has been associated with Alzheimer’s disease and is the subject of aggressive pharmaceutical research.

Is Alcohol a Healthy Choice?

So how does all of this interesting science inform us in terms of what we should do as it relates to drinking alcohol? I’d say that the evidence presented by these researchers is quite clear that there is a benefit to low to moderate alcohol consumption. We live in a world where we often consider that if something is good, then more of it is better, but that mentality flies in the face of what is actually revealed by the scientific data. The U-shaped curve graphs clearly show us that, at least as it relates to alcohol, there truly is a sweet spot in terms of your heart, brain, and overall health.

So if you want to enjoy alcohol healthily, my recommendations are as follows:

  • Consuming a maximum of two or three glasses of wine per day (preferably red) seems to be associated with health benefits not only for the heart but for the brain as well. Choosing a low-alcohol wine (12.5% or less) can reduce the potential downsides of alcohol consumption.
  • Wine should be organic and biodynamically farmed. These wines will be free of pesticides, herbicides, and other chemicals that pose a risk to our health.
  • Choose a wine that is free of additives. Did you know the FDA allows 76 different additives to be added to wines without being labeled?
  • As with any food in your diet (and you knew this was coming), you should absolutely check the sugar content of the wines you consume. There are wines available now that are specifically tested for fructose and glucose (sugars). Look for wines that have less than 1g of sugar per liter.

I receive many questions from people who are looking for high-quality natural wines. And as someone who enjoys the occasional glass of wine, I certainly understand how difficult it is to find wines without additives, added sugars, or high concentrations of alcohol.

To provide an option for those people, I partnered with Dry Farm Wines, which is my go-to company for high-quality natural wines. And as a member of our community, you can receive an extra bottle for $0.01 on your first order through this link.

So if you are looking for high-quality natural wines, try them out and let me know what you think!
