Richmond Foods is to launch a low-calorie ice cream in response to the growing fears over obesity.

The ice cream, called Skinny Cow, claims to have fewer than 100 calories per bar. The group already manufactures Weight Watchers ice cream for Heinz.

Meanwhile, as the government cracks down on food and drinks’ advertising targeting children, Coca-Cola has signed an agreement to sponsor the pop charts in a £2m deal.

The soft drink is to be advertised on the BBC’s Radio 1 chart countdown and on Top of the Pops, according to The Times.
