About one-quarter of American adults participate in Dry January, a vow to avoid drinking alcoholic beverages for the month, according to the polling firm Civic Science. Many people say they stop drinking for the month to exercise some discipline over their alcohol intake.
However, accumulating scientific evidence that no amount of alcohol consumption is safe, along with a surge in great-tasting non-alcoholic beers and mocktails, may convince more adults to reduce their alcohol intake long-term, according to medical experts.
In January, the U.S. Surgeon General issued an advisory on the growing body of scientific evidence showing the harmful effects of alcohol. The report summarized scientific evidence that alcohol consumption increases the risk of developing at least seven different types of cancer: mouth, throat, esophagus, larynx, breast, liver and colorectal.
“The direct link between alcohol use and cancer was first established in the late 1980s, and evidence for this link has strengthened over time,” the report states.
According to the Surgeon General, alcohol causes cancers in several ways. Alcohol breaks down into acetaldehyde, which damages DNA and can increase cancer risk. Alcohol also creates oxidative stress that can damage DNA, proteins and cells and increase inflammation. Alcohol can alter hormone levels, such as by increasing estrogen that can contribute to a higher risk of breast cancer. Alcohol also alters cells in the mouth and throat, allowing carcinogens to be absorbed easier.
“Now we finally have enough hard evidence to make this statement,” said Tracy Crane, director of lifestyle medicine, digital health and cancer prevention at Sylvester Comprehensive Cancer Center, part of the University of Miami Health System.
The risk is substantial among heavy drinkers. About five women out of 100 who consume two alcoholic drinks per day will develop cancer. About three in 100 men who drink two drinks a day will develop cancer.
About 72% of U.S. adults report they consume one or more drinks per week, according to the Surgeon General’s report. However, surveys show only 45% of Americans know that alcohol consumption increases cancer risk. In contrast, 89% of Americans are familiar with the increased risk of cancer linked to tobacco use.
The Surgeon General has proposed strengthening the warning labels on alcoholic beverages to warn about the risk of cancer. He also proposed reassessing the recommended limits for alcohol consumption to account for the growing scientific evidence showing harm. Right now, the U.S. Dietary Guidelines specify that women can safely consume one or fewer alcoholic drinks a day, and men can safely consume two drinks a day.
Consumers who wish to cut back can find additional resources, such as the “Rethinking Drinking” interactive website offered by the National Institute on Alcohol Abuse and Alcoholism.
Americans who wish to cut back will find it easier to find tasty non-alcoholic beverages in bars and to serve at home, Crane says. Consumers can find a growing array of nonalcoholic drink mixes and beers in stores.
It’s still too hard to find a variety of mocktails in many bars and restaurants, however.
“Alcohol is part of our culture, part of the social fabric,” Crane says. “It’s been around forever. There are clubs and hobbies that exist around it. So, it’s going to take time for people to embrace this.”
At home, try the new non-alcoholic beverages or make mocktails, Crane suggests. She encourages people to be adventurous. Take non-alcoholic drinks to a party and share with friends. Mix your nonalcoholic beverage in a nice glass, add garnishes and enjoy it the way you would an alcoholic drink.
