Confectionery major Cadbury New Zealand has been slammed by parents, schools and health groups for the high caffeine content in its latest chocolate bar, the Viking . The "chocolate bar with horns," which was recently launched in Tasmania, contains the stimulant guarana but consumers are only warned in the small print that: "As guarana is a natural source of caffeine, this product is not recommended for children under 15 years, diabetics, pregnant women, nursing mothers or persons sensitive to caffeine. Should only be used under medical or dietetic supervision." Many consumers have argued that the warning is in such fine print, that the majority of chocolate lovers would not, or could not, actually read it.
