Tests have revealed that more than half of leading soft drinks, like Coke and Pepsi, contain traces of alcohol.
According to tests carried out by the Paris-based National Institute of Consumption (INC) more than half of leading colas contain the traces of alcohol.
These include the brand leaders Coca-Cola and Pepsi Cola, while it is mainly only cheap supermarket versions of the drink, which are alcohol-free.
French magazine ‘60 Million Consumers,’ published the results of the tests in its latest issue.
They suggest that the alcohol levels are as low as 10mg in every litre, and this works out at around 0.001 per cent alcohol.
Those who are teetotal and drink Coke regularly will also be worried, as will those who choose it as an alternative to alcohol when they are driving.
Of 19 colas tested, the nine which did not contain alcohol were made by brands including Auchan, Cora, Casino, Leader Price and Man U-Cola.
Ten which had traces of alcohol in them included Coca-Cola, Pepsi Cola, Coca-Cola Classic Light and Coke Zero.
Both Coke and Pepsi companies suggested that natural fruit can ferment and produce minute traces of alcohol.
