Health experts will trawl through supermarket customers' shopping trolleys to tell them where they are going wrong.

It will all be done in the best possible taste, as part of a friendly approach to highlighting the food and drink that increase the risk of diabetes and heart disease.

Cambridgeshire Primary Care Trust dieticians will spend four hours next Thursday at Chatteris Co-op "advising customers on the small changes they can make that will me a big difference to their health".

Nicola McLean, the PCT's lead dietician, said: "More than 25 per cent of people in Cambridgeshire are obese, putting them at increased risk of type 2 diabetes and heart disease.

"But a small reduction in body weight and changes in lifestyle to decrease fat and increase fibre in the diet have been shown to reduce the risk of developing these diseases."

The dieticians will be on hand between 4pm and 8pm to advise customers on the small changes they can make at the supermarket that will make big differences to their health.

Ranjit Singh, Co-op's local affairs officer, said: "As a responsible retailer, the Co-operative Group believes that promoting good diet and health is a priority.

"This event will help our customers make informed choices about what food they buy and it will be interesting to find out whether there is an effect on food sales as a result.
