Television advertising has a lot of strict rules. You can’t, for example, sell Miracle growth tash cream- saying that it is clinically proven by your mate Dave, who is neither a chemist or a mate. So it made me double take to see this legal line of text on an advert for a low calorie breakfast cereal. It claims that people who eat low calorie cereal “tend to be” slimmer than those who don’t.” Yes well, those people who eat low calorie cereal also “tend to” eat less pies and lard sandwiches…now which lack of these do we thing is helping the most?
