More and more, researchers are delving into the health threats of soda pop, and scientists at Johns Hopkins Center for a Livable Future (CLF) may have found another. According to a new study published online in PLOS One, some types of caramel coloring may give off a potential carcinogen as a byproduct.
The researchers found that roughly 44 to 58 percent of people over age six have at least once can of soda a day., which may expose them to the carcinogen 4-methylimidazole (4-MEI), which arises during the manufacturing process for some kinds of caramel coloring.
To figure out just how much 4-MEI an individual might be sipping, the researchers looked at 2014 Consumer Reports data on the concentrations of this byproduct in 12 different soft drinks (11 sodas, 1 ice tea) from two metropolitan areas (New York and California).
As a couple examples of the variability, according to Nachman’s analysis, Goya Malta seemed to contribute an extra two cases of cancer per 10,000 people.
