Time to rethink drinking advice: Replace the ‘standard drink’ with practical guidance

(SeaPRwire) –   When you go out for a drink with coworkers, do you ask for 20 grams of ethanol or a Negroni? 10 grams of ethanol or a Pilsner? 16 grams of ethanol or a glass of Malbec?

Unless you are a scientist, you likely choose the latter. However, most alcohol guidelines are based on the former. Regulations in various nations have treated the public like human calculators, expecting them to understand “units” and “standard drinks” that are typically only found in laboratory settings.

The recently updated U.S. Dietary Guidelines represent a significant change in this strategy. By removing daily drink limits, they have essentially moved away from the “standard drink” model. This shift allows for a more straightforward message: adults who decide to consume alcohol should do so in moderation.

As international policymakers evaluate how to encourage moderate consumption, a vital question is whether current guidelines are practical for real-world use.

The illusion of the standard drink

The concept of a “standard drink” has always been a fiction, assuming a level of consistency and precision that exists in labs but not at social gatherings.

Glass dimensions differ, as do alcohol concentrations. Wine glasses are frequently topped off before they are empty, and spirits are often free-poured at home and in bars. Many of the most popular cocktails, such as a Martini or an Old Fashioned, often have an Alcohol by Volume (ABV) of 20%–30% or higher. Why are people being told that “a drink is a drink” when there are such massive differences in alcohol content between various beverages?

This issue is further complicated by the fact that a “standard drink” changes depending on the country. An alcohol unit in Vienna is twice the size of one in Madrid. If scientists and policymakers cannot agree on a single definition, it is unrealistic to expect the public to apply these abstract concepts to their daily lives.

Furthermore, alcohol is integrated into global cultures in diverse ways—from Polish vodka traditions to Japanese sake customs and Brazilian beer culture—that cannot be simplified into a technical formula. Instead, policy should emphasize functional health literacy and common sense.

Moving from mental math to behavioral changes

While any form of alcohol can be misused, not all consumption patterns carry equal risk. The most dangerous patterns typically involve the rapid consumption of high-strength products.

Consequently, stronger guidance should focus on “low and slow” patterns, prompting consumers to select lower-strength beverages and to pace their intake.

The “low and slow” method is more than just common sense; it is supported by evidence. A World Health Organization (WHO) review of Russian alcohol policies found that shifting consumption away from high-strength spirits was linked to improvements in several public health metrics (WHO Europe, 2019).

Beer is a natural fit for a “low and slow” drinking style. It has a lower ABV than other categories, and the total volume of liquid acts as a natural pacing tool. Furthermore, the beer industry’s use of single-serve containers eliminates the uncertainty found with free-poured drinks. A person drinking a 25cl beer at 5% ABV knows exactly what they are consuming without needing to do math.

Simultaneously, brewers are addressing a growing consumer interest in no- and lower-alcohol beers. In 2022, the market for these products expanded by over 7% across ten major global markets, with beer representing the majority of the category (IWSR, 2022).

This expanding market is influencing behavior; a UK study found that 20% of consumers reported a decrease in their weekly alcohol intake after they began drinking no- and lower-alcohol alternatives (Portman Group, 2022).

From theory to practice

Moderation is usually the result of small, practical decisions. As officials consider the best ways to encourage moderation, they should focus on bridging the gap between theory and reality by utilizing evidence-based strategies.

Experts have frequently advocated for regulations that distinguish between beverage types and alcohol concentrations—a method that is less restrictive for drinks with lower alcohol density, such as beer (Rehm et al., 2019).

Several governments are already taking the lead. For instance, many OECD members apply lower excise taxes to beer than to spirits and offer even lower rates for no- and lower-alcohol products, effectively encouraging both consumers and producers toward moderation (OECD, 2020).

Moderation is a behavior to be supported, not a mathematical problem to be solved. If the goal is to promote moderate consumption, it is time to move past the “standard drink” concept.
