Not all sugar-free carbonated drinks contain alternative sweeteners, so check the ingredient list for aspartame, saccharin, sucaralose and acesulfame potassium.
Elinav's findings on sucralose and saccharin go against decades of public health orthodoxy, which says artificial sweeteners have no effect on blood sugar.

In 1908, Harvey Wiley, who was then the head of the US Food and Drug Administration, sought to have saccharin eliminated from the food supply as an impure additive.
When he finally launched it at the World's Fair in Chicago in 1893, Fahlberg marketed saccharin as a " perfectly harmless spice" , 500 times sweeter than " the best sugar" .
The word " spice" cleverly hid the industrial origins of saccharin and the fact that it was made from coal tar: a sticky dark liquid that is a byproduct of burning coal.
