The trend in carbonated refreshments has changed so much that at present, sales of the original Coca-Cola and Pepsi-Cola drinks are extremely low, with consumers opting for sugar-free versions instead. For some months now, the big fizzy drinks companies have been battling it out to find a naturally sweetened cola drink which will retain the same characteristic taste, but they are falling far from their goal. The matter is so important, that Cola-Cola is offering a million dollars to scientists to come up with the much-coveted sweetener. Meanwhile, those consumers who buy products like Green Cola should keep their eyes open as the manufacturers of these types of drinks claim they are being sweetened with Stevia, when in fact the content of the latter is negligible. Instead, diet drinks are being sweetened with high amounts of sucralose, a chemical sweetener that is almost as dangerous as saccharin and aspartame.
