Drinking and health

Merrimack Valley Whiskey Review Logo

No doubt that it is safe for most people to drink small amounts of alcohol on a regular basis, and have moderate amounts of alcohol, more occasionally. But how much is a safe amount?

Alcoholism and other substance abuse issues certainly run in families, and people who know about this in their own family are wisely advised to avoid alcohol, or keenly monitor their drinking patterns. Some families have a history of certain diseases which alcohol can exacerbate, so the same caution is due here as well.  But what about people without high risk factors? For years medical studies have shown some small benefits of drinking wine, a few other studies showed small benefits from small amounts of any kind of alcohol. And we all know of family members or community members who had a drink every day, and lived well past 100.

For any person, too much alcohol at once can affect the brain, as such

Alcohol and Brain

But a growing number of studies are showing that that for many people, there are increased health risks at lower levels of alcohol consumption that once thought. For instance:

Moderate alcohol consumption as risk factor for adverse brain outcomes and cognitive decline: longitudinal cohort study

Moderate alcohol consumption as risk factor for adverse brain outcomes and cognitive decline, BMJ June 2017

Higher alcohol consumption over the 30 year follow-up was associated with increased odds of hippocampal atrophy in a dose dependent fashion. While those consuming over 30 units a week were at the highest risk compared with abstainers, even those drinking moderately (14-21 units/week) had three times the odds of right sided hippocampal atrophy. There was no protective effect of light drinking (1-<7 units/week) over abstinence. Higher alcohol use was also associated with differences in corpus callosum microstructure and faster decline in lexical fluency. No association was found with cross sectional cognitive performance or longitudinal changes in semantic fluency or word recall…. Alcohol consumption, even at moderate levels, is associated with adverse brain outcomes including hippocampal atrophy. These results support the recent reduction in alcohol guidance in the UK and question the current limits recommended in the US.

When reading such studies, we first ask, what is a “unit” of alcohol? In the UK we find this definition:

1 unit of alcohol = 10 millilitres (8 grams) of pure alcohol.

Typical drinks may contain 1–3 units of alcohol.

A ten ounce beer (300 ml) at 3.5% ABV contains about one unit;

A medium glass (175 ml) of 12% ABV wine has two units of alcohol

A small glass (50 ml) of sherry or port (20% ABV) contains about one unit.

Most whisky is 40% ABV.
In England, a single pub measure (25 ml) of whisky contains one unit.

A typical American miniature bottle is 50 ml -> 2 units.

A typical American pour at a bar is 2 ounces -> 60 ml -> 2.4 units

moderate alcohol usage and increased antioxidant intake decrease the risk of coronary heart disease.

Odds of dementia are lower among adults who consumed moderate alcohol, rather than none at all
