Shopping trolley that fights obesity by warning customers against unhealthy foods
A SHOPPING TROLLEY has been invented that could help prevent growing obesity figures. The trolley is able to recognise bar codes on foods, and can alert shoppers with a red light if the item they have chosen has a high-calorie, salt or fat content.
The system would work by inserting a store loyalty card into the trolley at the start of your shopping. The trolley will then be able to retrieve information on your previous purchases, and advise on offers that may be of interest to you. The scanning system will not only flag up unhealthy foods, it will also bring up details for all items put in the trolley, making nutritional information easier to follow and to read.
Trials on similar systems are already taking place at shops in the United States, and the makers are confident that British shoppers will embrace the idea.
