FOP labels typically indicate the amount (in grams) of fat, saturated fat, sugar and salt in a portion of the product, and some also pro-vide information on energy. Some labels accompany this information with text or traffic-light colours to indicate whether the level of these nutrients is ‘low’, ‘medium’or ‘high’ and others depict the contribution a portion of the product represents in terms of the percentage of the guideline daily amount (GDA) of the relevant nutrients. Products with more greens (low) and ambers (medium) and fewer reds (high) represent healthier choices.
