US Issues New Guidelines on Alcohol Consumption

Dr. Nicole Safier, a medical contributor, recently discussed new dietary guidelines for alcohol consumption on “Fox & Friends Weekend.” These guidelines emerge as drinking rates hit new lows.

Research indicates that even occasional binge drinking might increase the risk of serious liver disease by three times. A study from the University of Southern California (USC) discovered that, for individuals with pre-existing metabolic liver disease, just one binge-drinking episode per month could lead to a significant increase in progressive liver fibrosis.

The American Liver Foundation explains that progressive liver fibrosis marks an advanced stage of chronic liver disease, resulting in scar tissue buildup due to prolonged inflammation.

Experts stress that heavy drinking over short periods can seriously damage the liver. Dr. Brian P. Lee, leading the research and a specialist in liver transplants, mentioned, “Patients frequently inquire about how much they can consume. In hepatology, we often think of this in averages, categorizing patients based on their weekly alcohol intake.”

The study’s goal was to see how drinking patterns, not just overall intake, impact liver disease risk. Researchers analyzed data from six years of the National Health and Nutrition Examination Survey (NHANES), which involved over 8,000 adults.

They concentrated on individuals with metabolic dysfunction-associated fatty liver disease (MASLD), a condition linked to various metabolic health issues. Estimates suggest that MASLD affects about 25% to 30% of adults in the U.S., often stemming from obesity and associated health problems like type 2 diabetes and high blood pressure.

Over half of the adults surveyed reported occasional heavy drinking, and nearly 16% of those had MASLD. Findings showed that those who engaged in occasional heavy drinking—defined as at least once a month consuming four or more drinks for women or five for men—were at least three times more likely to experience progressive liver fibrosis compared to those who consumed the same amount over a longer period.

“The main point is that drinking patterns are very significant. Episodic heavy drinking is becoming increasingly common among U.S. adults,” Dr. Lee noted. The tendency to binge drink was particularly high among young adults and men, with more drinks during each session correlating with greater liver scarring.

The study’s findings appeared in the journal Clinical Gastroenterology and Hepatology.

Dr. Lee emphasized that it’s not merely about how much people drink but how they drink. Many patients express curiosity about whether it’s better to drink less on weekdays and more on weekends, but the research indicates that this isn’t a healthy approach. “Episodic heavy drinking poses more risks than long-term consumption,” he stated.

Potential Limitations

The research has its limitations; it was observational and could not definitively establish binge drinking as a cause of progressive liver fibrosis. Additionally, it relied on self-reported alcohol consumption, which can often be unreliable. The results mainly pertain to those with MASLD and might not apply universally.

Lee also suggested that a longitudinal study would be more beneficial to explore the risks of liver-related issues tied to drinking habits. “Considering that more than half of adults report engaging in episodic heavy drinking, this warrants significant attention from both healthcare providers and researchers to improve prevention and treatment strategies for liver disease,” he added.

Julian Braithwaite, from the International Alliance for Responsible Drinking, remarked that the study reinforces the idea that “how you drink matters.” He pointed out the dangers of binge drinking versus moderate drinking, stressing the need for individuals to recognize harmful patterns and make informed choices.

Dr. Amanda Berger from the Distilled Spirits Council emphasized that research highlights potential health risks from excessive drinking and binge drinking. She encourages individuals to consult healthcare providers to tailor advice based on personal health factors. Berger reiterated that moderation remains key, according to the new Dietary Guidelines for Americans, which suggest limiting intake to one drink per day for women and two for men.
