Traffic light food labels were first introduced in the UK with the aim of providing consumers with a clearer indication about the amount of salt, sugar or fat contained in the products they buy. They are red, amber or green based on the quantity of specific nutrients, allowing the consumer to quickly decide which product to choose.
“To make healthier choices look for foods which have more green and amber and very few red traffic lights,” Sainsbury’s says on its website, as well as recommending its own range of products with few, if any, red traffic lights.
The scheme entered into force in 2013 but is still voluntary at this stage and only applies to about a third of food sold in Britain.
In September last year, local authorities urged the UK government to make it universal, saying consumers were confused.
