Ten countries in Latin America and the Caribbean have enacted laws or regulations on Front-of-Pack Nutrition Labeling (ENPFE). Seven of these have implemented, or are in the process of implementing, nutrition warnings with black octagons, including Argentina, Chile, Colombia, Mexico, Peru, Venezuela and Uruguay.

According to the Food and Agriculture Organization of the United Nations (FAO), these nutrition warnings with black octagons effectively reduce the intention to purchase products with excess calories, sugar, sodium and saturated fat, help consumers make healthier choices and contribute to the reformulation of food products.
