Diet Cola Drinks Shown to Contain More Caffeine than Regular Variants
04 Aug 2014 --- New research is believed to show that diet cola drinks contain higher levels of caffeine than their regular counterparts. Soft drinks manufacturers are not required to label the levels of caffeine in their products, although rules EU due to come out this December will force companies to put a ‘high caffeine content’ warning on products containing more than 150mg of caffeine per litre.
Laboratory tests reportedly showed that Diet Coke contained 139mg per litre, compared to 109mg in regular cola, while Diet Pepsi also had more caffeine than its regular variant.
The research, commissioned by the Sunday Times, also showed similar discrepancies in own-brand cola drinks.
Nutritionists and child health campaigners have warned that high-caffeine drinks could pose a risk to health, particularly to children.
