Man dies from eating bags of black licorice: health concerns you should know

A Massachusetts construction worker’s love of black licorice wound up costing him his life. Eating a bag and a half every day for a few weeks threw his nutrients out of whack and caused the 54-year-old man’s heart to stop, doctors reported Wednesday.

“Even a small amount of licorice you eat can increase your blood pressure a little bit,” said Dr. Neel Butala, a cardiologist at Massachusetts General Hospital who described the case in the New England Journal of Medicine.

The problem is glycyrrhizic acid, found in black licorice and in many other foods and dietary supplements containing licorice root extract. It can cause dangerously low potassium and imbalances in other minerals called electrolytes.

Eating as little as 2 ounces of black licorice a day for two weeks could cause a heart rhythm problem, especially for folks over 40, the U.S. Food and Drug Administration warns.

“It’s more than licorice sticks. It could be jelly beans, licorice teas, a lot of things over the counter. Even some beers, like Belgian beers, have this compound in it,” as do some chewing tobaccos, said Dr. Robert Eckel, a University of Colorado cardiologist and former American Heart Association president. He had no role in the Massachusetts man’s care.

The death was clearly an extreme case. The man had switched from red, fruit-flavored twists to the black licorice version of the candy a few weeks before his death last year. He collapsed while having lunch at a fast-food restaurant. Doctors found he had dangerously low potassium, which led to heart rhythm and other problems. Emergency responders did CPR and he revived but died the next day.

The FDA also notes that potassium levels are usually restored with no permanent health problems when consumption of black licorice stops.

The FDA permits up to 3.1% of a food’s content to have glycyrrhizic acid, but many candies and other licorice products don’t reveal how much of it is contained per ounce, Butala said. Doctors have reported the case to the FDA in hope of raising attention to the risk.

According to a consumer alert issued by the FDA in 2017. glycyrrhizin can cause the body’s potassium levels to fall, which can cause abnormal heart rhythms, high blood pressure, swelling, lethargy and congestive heart failure.

Jeff Beckman, a spokesman for the Hershey Company, which makes the popular Twizzlers licorice twists, said in an email that “all of our products are safe to eat and formulated in full compliance with FDA regulations,” and that all foods, including candy, “should be enjoyed in moderation.”

According to a 2019 USA Today report, if you’re eating a mainstream version of the treat, your risk of adverse health effects is low, according to Craig Hopp, the natural products expert at the National Center for Complementary and Integrative Health.

Hopp said that while there is a legitimate concern about consuming real licorice root, many candies don’t pose a threat. Many licorice-flavored products made in the United States are made with anise oil, which has the same smell and taste, according to the FDA.

“The candy people get at Halloween likely contains no actual licorice root,” Hopp said. “It’s just artificial flavoring. Thus, it contains no glycyrrhizin.” Check all product labels carefully to be sure.
