Weight stigma in Mexico and front-of-package labeling. A systemic review

Background. Front-of-package food labeling is a public health strategy implemented to reduce the consumption of processed food to decrease the incidence of obesity in Mexico. Although there is an increasing focus among public health officials on implementing policies designed to address obesity, much less attention has been paid to how these policies could impact those with disordered eating, despite the fact that millions suffer from such illnesses. Objective. The aim of this article is to present scientific literature related to front-of-package labeling and its impact on obesity and eating disorders. Method. Papers related to nutrition labels and obesity and eating disorders were reviewed. Results. The papers reviewed found no significant improvement regarding the consumption of processed food. Other measurements, including nutritional education, availability, physical education, and body-image acceptance, have a better impact on nutritional health. Discussion and conclusion. Front-of-package labeling is regarded as an important measure in the attempt to reduce obesity levels. However, there is insufficient scientific evidence to suggest that this type of labeling reduces the consumption of processed foods in patients with obesity.
