Science around Moderate Alcohol Consumption

What are the current consumption guidelines?

The Dietary Guidelines for Americans provides advice on what to eat and drink to meet nutrient needs, promote health, and help prevent chronic disease from U.S. Department of Agriculture in cooperation with U.S. Department of Health and Human Services. The current version says "Consume less alcohol for better overall health." Previous guidance, such as in Dietary Guidelines for Americans for 2020-2025, recommends that adults of legal drinking age who choose to drink do so in moderation, limiting intake to 2 drinks or less in a day for men and 1 drink or less in a day for women, on days when alcohol is consumed.

People Who Shouldn’t Drink at All:

The Guidelines note that some people should not drink alcohol at all, including:

people who are pregnant or might be pregnant
individuals with certain medical conditions or are taking certain medications that can interact with alcohol
anyone recovering from an alcohol use disorder or if they are unable to control the amount they drink
for those with a family history of alcoholism, be mindful of alcohol consumption and associated addictive behaviors

The Guidelines for 2020-2025 also stated that the following people should not consume alcohol:

people younger than age 21

Risks of Moderate Drinking:

Recent studies have shown that even drinking at these "moderation" levels have negative impacts on our health and wellbeing, including increasing risks of cancers such as, mouth and throat, voice box (larynx), esophagus, colon and rectum, liver, and breast. The Dietary Guidelines for Americans for 2020-2025 also DOES NOT recommend that individuals who do not drink alcohol start drinking for any reason. It further recommends that adults of legal drinking age who decide to drink alcoholic beverages, drink less for better health, which is a stance shared by current Guidelines.

Drinking at levels above the 2020-2025 outlined moderate drinking guidelines significantly increases the risk of short-term harms, such as injuries, as well as the risk of long-term chronic health problems, such as some types of cancer.

Science around Moderation:

The Dietary Guidelines for Americans for 2020-2025 note, “Emerging evidence suggests that even drinking within the recommended limits may increase the overall risk of death from various causes, such as from several types of cancer and some forms of cardiovascular disease. Alcohol has been found to increase risk for cancer, and for some types of cancer, the risk increases even at low levels of alcohol consumption (less than 1 drink in a day)."
Although past studies have suggested that moderate alcohol consumption has protective health benefits (e.g., reducing risk of heart disease), recent studies show this may not be true. While some studies have found improved health outcomes among moderate drinkers, it’s impossible to conclude whether these improved outcomes are due to moderate alcohol consumption or other differences in behaviors or genetics between people who drink moderately and people who don’t.
Most U.S. adults who drink don’t consume alcohol every day. This makes it important to focus on the amount people drink on the days that they drink. Even if women consume an average of 1 drink per day or men consume an average of 2 drinks per day, binge drinking increases the risk of experiencing alcohol-related harm in the short-term and in the future.

What is considered heavy alcohol use (or heavy drinking)?

NIAAA defines heavy alcohol use as follows:

For men, consuming five or more drinks on any day or 15 or more per week
For women, consuming four or more drinks on any day or 8 or more per week
SAMHSA defines heavy alcohol use as binge drinking on 5 or more days in the past 30 days.

Count your drinks:

Check in with your alcohol consumption by accurately counting your drinks. One standard drink contains 0.6 ounces of pure alcohol. Different beverages have different concentrations of alcohol listed as percent alcohol by volume (ABV) percentage. As the alcohol concentration goes up, the amount of liquid needed to equal one standard drink goes down. Examples of standard drinks include:

12oz of 5% ABV beer
8oz of 7% ABV malt liquor
5oz of 12% ABV wine
1.5oz of 40% (80 proof) ABV distilled spirits - such as gin, vodka, rum, whiskey, so on

Let's say you are out at restaurant and order a craft beer that is 9% ABV in a pint glass. A standard US pint glass holds 16oz. Drinking that one beer is the equivalent of 2.4 standard drinks!
