Nutrition traffic lights

A traffic lights system (red, orange, green) makes it possible to identify at a glance the amount of fat, saturated fats, sugars and salt contained in food products.

This traffic light system has been established by the United Kingdom's Food Standards Agency (FSA). It is used by some manufacturers on a voluntary basis in Great Britain, but was rejected by the European Commission in 2010.

On Open Food Facts, when the nutritional values are known, the traffic lights are displayed on the product pages.

The calculation formula defining the colors of the lights is described on the Tri-color traffic lights page - instructions (French) of the Foodwatch association.

for 100g	Small amount	Moderate amount	High quantity
Lipids	up to 3g	from 3g to 20g	more than 20g
Saturated fatty acids	up to 1.5g	from 1.5g to 5g	more than 5g
Sugar	up to 5g	from 5g to 12.5g	more than 12,5g
Salt	up to 0.3g	from 0.3g to 1.5g	more than 1,5g

For drinks, all values are divided by 2.
