Birmingham researchers propose that the UK food labelling which currently is used on individual products should be expanded to the level of an entire supermarket receipt. The ‘traffic light system’ shows the total data for calories, sugar, fat and salt in a person’s shop and highlights the total in a green, amber or red colour.
The intention is that this would help people make healthier choices about their food. How this would control for size of household or frequency of shopping is unclear.
