If you need another reason to cut back on sugar-laden soft drinks, here’s a scary one: many contain an ingredient that may cause cancer.
Sunday Times The Power Report By Megan Power, 2015-06-07
Soft drink consumers are being exposed to an avoidable, unnecessary cancer risk. Food activist and researcher, Sonia Mountford has been waiting since January 2013 for a commitment by Coca Cola South Africa to align their use of the carcinogenic substance 4-MEI to that of the United States. Megan Power managed to get a timeline from them.
According to a world health authority, popular cooldrinks such as Coca-Cola could increase your risk.
The 4-MEI compound can be in the caramel colouring used in a variety of foods, from bread to beer, dark sauces – such as soy and barbecue – pancake syrup and soups.
It also occurs naturally when coffee beans, meat, or other foods are roasted or processed.
However, experts believe that people are mainly exposed to the colouring through cooldrinks.
In California, 4-MEI is on the state’s list of toxic substances, and products sold there that expose consumers to more than 29 micrograms of 4-MEI a day have to carry a cancer warning.
Which probably explains why Coke has been slow to roll out the reduced-4-MEI formula in areas and countries where it’s not under legal pressure to do so, including South Africa.
For now, local consumers are drinking at least 14 cooldrink brands containing 4-MEI at undisclosed levels.
But not for long. Coke’s roll out of the reduced 4-MEI recipe is under way and will be complete by the end of September.
In four months, all affected products containing the caramel colourant here – Coke, Coke Zero, Coke Light, Tab, Fanta Pineapple, Sparletta Iron Brew, Sparletta Blackcurrant, Sparletta Apple, Schweppes Ginger Ale and Krest Ginger Ale, the Powerplay range and Minute Maid Grape Nectar – will comply with California’s regulations.
Unfortunately, despite weeks of back and forth with Coca-Cola South Africa, that’s as much as I could get. The company declined to divulge specifics on 4-MEI levels at the moment, new roll-out levels, or even the percentage reduction, citing company confidentiality.
The beverage manufacturer is adamant that, regardless of current levels in its drinks, 4-MEI poses no threat.
“The science does not support [California’s] position, and there is no public health risk that justifies the requirement of a warning,” said Coke SA’s head of communications, Zipporah Maubane. “We want to assure everyone that all of our products – whether they have the reduced-4-MEI caramel or not – are safe.”
When first approached, Coke SA sent me a six-line statement saying the company was committed to product safety and had rolled out the reduced recipe in South Africa. However, when I requested more details, it revealed that the changeover had started only in April, with no set time frame for completion.
Coke responded to her saying there was no risk from 4-MEI. When she persisted, Coke said a timeline to roll out the new recipe was “still being developed”. A year later, Mountford queried progress. She never got a response.
“The fact is that even small amounts of 4-MEI can pose great risk to our health since we are already overwhelmed by carcinogenic substances throughout the day,” said Mountford. “At least, let’s protect our children.”
“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,” said Nachman, the senior author of a study, published in February, that analysed national cooldrink consumption in the US.
The study was a follow-up to testing done in 2013 to measure 4-MEI content in 11 US soft drinks. The study found that average 4-MEI levels ranged from 3.4 to 352.5 micrograms per 12-ounce (355ml) bottle or can.
In another set of published results, in 2012, a US consumer watchdog group, the Center for Science in the Public Interest, looked at levels of 4-MEI in Coke samples in nine countries. They ranged from four to 267 micrograms of 4-MEI per 355ml.
