Spain has adopted the nutri-score traffic light system as part of its plans to tackle the nation’s obesity problem, reports just-food.

The nutri-score code consists of a scale with letters A to E (A coloured green and E in red) to display how healthy a food item is based on its contents of fat, salt, calories, fibre and protein.

Spanish health minister, Maria Luisa Carcedo announced the plans on 12 November, as well new initiatives to promote good nutrition and physical activity in schools and institutes.

The measures will prevent the sale of food and beverages containing a high content of saturated and trans fatty acids, sugar, salt and calories in schools and institutes. Advertising unhealthy foods aimed at children under 15 will be limited through self-regulation.

Carcedo said the nutri-score system will "provide citizens with more accurate information on nutritional quality".

She added: "This information will allow citizens to compare with other similar products easily and make an informed and motivated decision to follow a healthier diet."

In February, the Spanish government announced plans to make 10% cuts in the fat, salt and sugar content of more than 3,500 food and drink products over the next three years, with more than 500 companies voluntarily committed to the plans.

Spanish authorities have not said when the nutri-score system would be introduced or whether it would be mandatory, just-food said.

The nutri-score system was set up in France earlier this year and was due to be introduced in Belgium and Portugal.
