Introduction: Food is a process that carries implicit socio-cultural elements in a specific historical moment. The changes in the diet caused an increase in problems of obesity and Chronic Non-Communicable Diseases in Mexico. Measures have been taken through public policies that seek to reduce the effects of the consumption of foods with high energy value, one of them is the nutritional labeling of foods.

Development: As the first axis, a sociohistorical reconstruction is developed around food labeling in Mexico as an initiative that is part of an international public policy to present nutritional infor- mation for the selection and consumption of food. In a second moment, an analysis is carried out from a critical position on the implementation and exercise of decision-making for the consumption of said products, since it is subject to a complex network of sociocultural and individual factors that determine and are determinants of styles. and frequency of consumption of the products.

Conclusions: The new labeling with nutritional information is an information tool for the selection in food consumption to face the problem of overweight and obesity in Mexico. However, eating habits and practices respond to sociocultural and economic elements that are above healthy lifes- tyles and a culture of prevention. It is necessary to build and promote community participation-action that promotes tools such as nutritional labeling to make its objectives effective.

Between July and August, the country conducted field research in the three departments of the central axis to evaluate and compare the effectiveness of front-of-pack nutrition labeling on food products with a view to its future implementation.
It has been shown that front-of-pack nutrition labeling on food products helps consumers to be more aware of the potential harmful effects of a product and to choose healthier alternatives.
The research process in Bolivia is led by the Ministry of Health and Sports, through the Directorate of Health Promotion and the nutrition areas of the Departmental Health Services (SEDES in Spanish) of Cochabamba, Santa Cruz, La Paz and the Regional Health Service (SERES) of El Alto, with technical support from the Pan American Health Organization/World Health Organization (PAHO/WHO) and the Universidad Mayor de San Andrés (UMSA in Spanish).

The results of this research will guide the identification and development of an appropriate front-end nutrition labeling scheme for consumers in Bolivia, allowing the population to easily identify when a product is excessive in critical nutrients associated with obesity and Non-Communicable Diseases (NCDs in Spanish). It will also help consumers make informed choices regarding the foods they consume and discourage the consumption of products with excessive sugar, fat and sodium content. This will ultimately result in contributing to the protection of public health and the reduction of health costs, including improving the economy.

The objective of the essay is to analyze the transition of nutritional labeling in Mexico and the factors that hinder its effectiveness in the university population. In recent years, there has been a need to have a labeling system that is easy to understand and that promotes the choice of healthy food products. Previously, GDA labels are implemented between the Mexican government and the processed food industry; however, it lacked scientific support and required mathematical calculations or advanced knowledge about nutrition in order to be interpreted. With the pressure of civil groups and in the context of obesity in Mexico, there was a transition from labeling in 2020 to Warning Seals, successfully implemented in South American and European countries, with the purpose of easily communicating excessive content of critical nutrients, however, controversies have arisen in this regard. On the other hand, there are limitations in the effectiveness of labeling, such as attitudes towards a healthy diet, knowledge about nutrition and lack of understanding.
