Thousands of Americans drink soda everyday and these individuals do not just increase their sugar intake and their odds of packing unnecessary weight. They also put themselves at risk of developing cancer.
The ingredients of colas and other soft drinks typically include a caramel coloring, which gives these beverages their distinct caramel color. Unfortunately, some types of this food coloring contain a chemical known as 4-methylimidazole (4-MeI), a potential carcinogen.
Now, an analysis published in the journal PLOS ONE on Feb. 18 has revealed that more than half of Americans between 6 and 64 years old sip amounts of soft drinks per day that could expose them to amounts of 4-MeI that could raise their risks of developing cancer.
Keeve Nachman, from the Johns Hopkins Center for a Livable Future, and colleagues looked at a previous study conducted by researchers from the Consumer Reports that analyzed the concentration of 4-Mel in 12 brands of sodas and soft drink. They also analyzed the soft drinks consumption in the U.S. using data from the National Health and Examination Survey (NHANES) to estimate the potential cancer risks of soft drinks consumption.
The researchers found that the average soda consumption in the U.S. ranges from a little over 12-ounces(1 can) to almost two and a half cans of soda per day with the biggest consumers being those between 16 and 44 years old. Children between 3 to 5 years old were likewise found to drink soft drinks on a typical day averaging about two thirds of a can.
The researchers said that at the rate at which Americans consume soda, they expect the emergence of between 76 to 5,000 cancer cases in the U.S. over the next seven decades that can be attributed to exposure to 4-MeI alone.
"It appears that 4-MeI exposures associated with average rates of soft drink consumption pose excess cancer risks exceeding one case per 1,000,000 exposed individuals, which is a common acceptable risk goal used by some U.S. federal regulatory agencies," the researchers wrote.
Nachman said that soft drink consumers get exposed to unwanted and avoidable cancer risks from an ingredient that is added to beverages and other foods for aesthetic purposes and this raises concerns on the continued use of caramel coloring in sodas. The Food and Drug Administration said that it will take a closer look at the use of this artificial coloring in a variety of foods.
