Coca-Cola North America has come under attack following its decision to launch a Splenda-sweetened version of Diet Coke. Generation Green, an advocacy group claiming to favour corporate and governmental policies that will "allow children to grow up protected from exposure to toxins," has claimed that Splenda is being sold under false pretences.

"While Coke may be the "real thing," Splenda most certainly is not," said Generation Green executive director Rochelle Davis in a statement.

"The Coca-Cola Company's decision to begin selling a new version of Diet Coke sweetened with Splenda artificial sweetener is just the latest development as Splenda works its way into the marketplace under false pretences," Davis continued.

"Splenda's success to date is based on an aggressive and totally misleading marketing campaign specifically designed to confuse consumers into believing that Splenda is a natural sugar-based product. Nothing could be further from the truth."

Last month, Generation Green called on the Federal Trade Commission to investigate a marketing campaign being conducted by Johnson & Johnson's McNeil Nutritionals LLC for its artificial sweetener, Splenda.
