Public health researchers have analyzed soda consumption data in order to characterize people’s exposure to a potentially carcinogenic byproduct of some types of caramel color. Caramel color is a common ingredient in colas and other dark soft drinks. The results show that between 44 and 58 percent of people over the age of six typically have at least one can of soda per day, possibly more, potentially exposing them to 4-methylimidazole (4-MEI), a possible human carcinogen formed during the manufacture of some kinds of caramel color.
Building on an analysis of 4-MEI concentrations in 11 different soft drinks first published by Consumer Reports in 2014, researchers led by a team at the Johns Hopkins Center for a Livable Future (CLF) estimated exposure to 4-MEI from caramel-colored soft drinks and modeled the potential cancer burden related to routine soft drink consumption levels in the United States.
“Soft drink consumers are being exposed to an avoidable and unnecessary cancer risk from an ingredient that is being added to these beverages simply for aesthetic purposes,” says Keeve Nachman, PhD, senior author of the study…”This unnecessary exposure poses a threat to public health and raises questions about the continued use of caramel coloring in soda…”
While there’s currently no federal limit for 4-MEI in food or beverages, Consumer Reports petitioned the Food and Drug Administration to set limits for the potential carcinogen last year. It also shared the findings with the California Attorney General’s office, which enforces the state’s Proposition 65 law aimed at reducing consumers’ exposure to toxic chemicals. Under this state law, any food or beverage sold in the state that exposes consumers to more than a specific amount of 4-MEI per day requires a health-warning label.
Another one I don’t have to worry about. I actually keep most New Year’s Resolutions as long as I limit myself to one at a time. Make it simple. Make it achievable.
A number of years ago I stopped consuming any carbonated beverages.
