In the communication between producers and consumers, food labeling is fundamental since it allows to know the conformation and nutritional facts of food products. This work is carried out to develop a comparative study on the laws of front labeling as a guarantee of legal protection to consumers, it is a study of doctrinal and jurisprudential review on the protection of the right to health of consumers. It can be evidenced that the main models of front labeling are interpretative, non-interpretative, semi-interpretative and hybrid, of which the most used are the food guides and nutritional traffic lights. The guide system is used in Brazil, Chile, the United States, Japan and Great Britain, while the traffic light system is more widely used in Bolivia, Ecuador, Mexico and Russia.
