A common question from our members is “how much alcohol can I drink?”. This is a question that interests people of every age, 30 to 90+.
This article will explain how to choose how much alcohol to drink for optimal health, including dementia prevention.
How much can I drink?
Based on the latest research, most people should aim to drink less than 7 drinks a week, and ideally less than 2.
If you have a genetic risk for dementia, such as the APOE4 allele, you should ideally aim for zero alcohol intake most weeks.
Where do we get these numbers?
Recommendations from different leading health organizations vary based on where you live.
In Canada, the recommendation is no more than 2 drinks a week (read more here).
In other countries, the recommendation is less than 7 drinks a week (for women or anyone over the age of 65) or less than 14 drinks a week for men under the age of 65.
Why are men and women given different targets? It has to do with our generalized differences in body size, water content, and alcohol dehydrogenase activity.
In those with liver disease, pancreatic disease, esophageal disease, or pregnancy, no alcohol intake at all is recommended.
Two drinks a week is likely safest when it comes to brain health.
What happens if I drink a lot more?
There is no debate when it comes to drinking a lot of alcohol (meaning more than the numbers listed above) - it’s no good!
Drinking large amounts (more than 3 a day) is linked to a number of very serious health conditions including:
liver disease (known as cirrhosis)
memory problems (known as alcohol-related dementia)
muscle loss (known as sarcopenia)
numbness in your hands and feet (known as neuropathy)
trouble walking (known as ataxia)
heart disease and stroke (known as cardiovascular disease)
cancer (oral, gastrointestinal, breast, colorectal)
and early death
If you think this might apply to you, you can read Aldora’s guide to cutting back here.
If you find yourself drinking more than the recommended amount, cutting back could have huge health benefits.
Is drinking linked to dementia?
Drinking more than 12 drinks a week results in an 18% increased lifetime risk of dementia, according to the Lancet commission on dementia prevention.
This risk goes up to 22% when the drinking occurs during midlife (age 40 to around your 60’s).
Historically, there have been other studies - including a large study over 14 years in Japan - that suggests not drinking at all could also increase risk of dementia.
What to make of this? Right now experts do not recommend that you start drinking for dementia protection - if you don’t drink anything, it’s probably best to stick to that for now.
Another case of where balance might be the winning answer.
What about other risks and benefits of minimal drinking?
Research has been done in people who don’t drink in excess - meaning 1 drink a day; 1 drink every other day; or those who spread their total drink consumption out over the week rather than drinking most of their weekly amount in one sitting - with the following results:
Heart Health
Drinking one 4-oz glass of red wine with dinner might be protective against worsening heart problems in people with type 2 diabetes who already have heart disease (read the studies here and here).
This is thought to be through natural anti-oxidant and anti-inflammatory properties of red wine that other types of beverages lack.
Cancer
When it comes to cancer, in a large study of healthcare workers in the US there was no real increase in most cancers with light alcohol use except for breast cancer, in which women had an increased relative risk of 6-20%.
Several other studies have also shown a link between alcohol and breast cancer.
The American Society of Clinical Oncology recommends against any alcohol consumption for cancer protection (especially, again, when it comes to excessive use).
Alcohol seems to have effects on your heart, lifespan, and cancer risks, sometimes good, sometimes bad.
Do we need more research?
Experts agree it can be hard to combine different studies on drinking, making a 100% guaranteed answer for everyone’s personal circumstances hard to give.
While with time research might shed more light, we also think it would be good to consider a holistic view to such research - in particular, does it matter how or why we drink?
Are you drinking alone to numb emotional pain? Or are you having a glass of red wine over dinner with friends or family? The second option could be less harmful than the other.
As with everything in life, it is probably not just what we do, but how we do it that dictates our outcomes to some degree.
This takes into consideration more than just the “biomedical” model of disease, and looks instead at our actions as part of a holistic life that integrates more than just medicine when considering the question of disease.
Does how or why we drink affect the health outcomes?
Why it comes down to balance
In most things in life, there is a sweet spot in between “not enough” and “too much”.
At the end of the day, less alcohol is probably best, a little might be okay, and lots leads to significant suffering.
While some research shows a link to light alcohol use leading to lower rates of dementia, we don’t suggest that people drink to protect their brains, since the research is not 100% clear right now.
In closing…
Here’s a run-on sentence that sums up how this article could play-out in your real life: try to have weeks without any alcohol, and don’t drink every day, but still enjoy that get-together with friends, family, or on a special occasion. Find balance in your life so you live long and well.
Use alcohol to serve you, and if you’re drinking more than the recommended amount, chances are it’s causing more harm than good. Read this; drinking less is possible.
