Unsurprisingly, Cadbury's salmonella scare was the biggest story of the week. As The ­Daily Telegraph pointed out: luckily column inches don't correlate to share prices. But ­punctuating the coverage were a couple of quirky new product development stories that no doubt will have got ­people talking. The Mirror and The ­Daily Telegraph both followed our story on the launch of a new iced tea product from Austria that contains cannabis - or at least it contains the non-narcotic elements of cannabis. That probably means students won't be flocking to buy it, but if you read The Guardian that kind of wanton marketing won't cut it anyway. They ran a piece on how to educate students and young people on the tactics used by marketeers to get people to buy things, particularly unhealthy foods. That's something the clever people at Nestlé have been working on. According to The Independent On Sunday, they've come up with a ­cereal bar that suppresses surges in blood sugar levels.

Unilever has been working on something even more wacky. The Times and The Daily Mail ran pieces on its efforts to create an ice cream that doesn't make you put on weight, using the blood from a deep sea eel. It all sounds a bit Frankensteinish, but Unilever insists that although it is using GM techniques to do this, the technique leaves no GM traces in the food. You should have said... Eel blood ice cream all round then, please!
