Food labeling in Mexico

Food labeling in Mexicorefers to the official regulations requiring labels onprocessed foodssold within the country to help consumers make informed purchasing decisions based onnutritional criteria. Approved in 2010 under theNorma Oficial Mexicana(NOM)NOM-051-SCFI/SSA1-2010(often shortened toNOM-051),the system includes Daily Dietary Guidelines (Spanish abbrebriation: GDA). These guidelines focus on the total amounts ofsaturated fats,fats,sodium,sugars, andenergy(kilocalories) per package, the percentage they represent per serving, and their contribution to the daily recommended intake.
After its implementation, several studies assessed the effectiveness of the system. The results indicated that most respondents were unaware of the recommended intake levels, struggled to understand the meaning of the values provided by the system, and did not use the system when shopping. Additionally, most undergraduate nutrition students could not interpret the system correctly when questioned.In response, theSecretariat of Healthlooked for alternatives to the system. In 2016, Chile published asimplified food labeling system, which inspired the creation of a similar system for Mexico.
In 2020, the system was revised and updated with the Food and Beverage Front-of-Package Labeling System (Spanish: {Spanish abbrebriation: SEFAB), developed and implemented by theNational Institute of Public Health[es](INSP).By the end of the year, labeling standards were applied to 85% of food products consumed in Mexico,one of themost obese countriesin the world. One year after its implementation, studies found the system had an insignificant impact on sales. However, many companies still adjusted their formulas to reduce risk factor levels.
The influx of foreign food industry capital since the 1980s, coupled with the implementation of theNorth American Free Trade Agreement(NAFTA) in 1994, led to a sharp rise in the import ofprocessed foodsinto Mexico. These changes triggered an irreversible shift in the country's eating habits and a dramatic increase inobesityrates. In the 1980s, these rates were just 7%.Since then, Mexico has become the leading consumer of processed foods in Latin America and the fourth-largest worldwide, as of 2017.
In 2010, theSecretariat of Health(SALUD) requested the establishment of a food labeling norm. After its approval, it was designed as NOM-051-SCFI/SSA1-2010 under theNorma Oficial Mexicana(NOM) standards. The system, called Daily Dietary Guidelines (Spanish:Guías Diarias de Alimentaciónor GDA), was based on the total amount ofsaturated fats(grasas saturadas),fats(grasas),sodium(sodio),sugars(azúcares) andenergy(calorías) represented inkilocaloriesper package. It also indicated the percentage these amounts represented per serving and their contribution to daily recommended intake.
TheNational Institute of Public Health[es](INSP) began investigating the effectiveness of the labeling system in 2011.Their findings showed that it was largely ineffective, as most nutrition students were unable to interpret it correctly.In 2016, the National Health and Nutrition Survey (Spanish:Encuesta Nacional de Salud y Nutrición) included questions about understanding the GDA food labeling system. The results revealed poor comprehension nationwide. The INSP reported that 97.6% of respondents were unaware of the appropriate calorie intake values for children aged 10 to 12, over 90% did not know the recommended daily calorie intake for adults, and 66.4% never used the GDA system to inform their purchases.Additionally, a survey conducted by INSP and theUniversity of Waterloofound that only 6% of adults understood the GDA system.
In 2013, thefederal government of Mexicolaunched the 2013 National Strategy for the Prevention and Control of Overweight, Obesity and Diabetes (Spanish:Estrategia Nacional para la Prevención y el Control del Sobrepeso, la Obesidad y la Diabetes),a set of measures by aimed at addressing the obesity crisis and chronicnon-communicable diseasessuch ashypertension,diabetes, andcancer. The strategy highlighted that the current levels of overweight and obesity in Mexico posed a significant threat to the sustainability of the healthcare system, due to their link to non-communicable diseases and the high costs associated with specialized care.Statistics showed that 42.6% of men over 20 were overweight, and 26.8% were obese. Among women, 35.5% were overweight and 37.5% were obese.By 2018, 75% of adults were either overweight or obese.
In 2016, thegovernment of Chileenacted theFood Labeling and Advertising Law, which introduced simplified and prominentwarning labelsto indicate excess calories,added nutrientsandadditiveslinked to non-communicable diseases. Inspired by this system, the INSP formed a committee of national academic experts to develop a new regulation for front-of-package labeling of food and non-alcoholic beverages. TheSecretariat of Economy(SE) and theFederal Commission for the Protection against Sanitary Riskorganized working groups, resulting in a draft standard submitted for public consultation from 11 October to 10 December 2019, gathering 5,200 comments.Simultaneously, civil society organizations, including theAlianza por la Salud Alimentaria(Alliance for Food Health), launched a public campaign to inform the population about these efforts.
On 29 October 2019, reforms and additions to the Mexican General Health Law were approved, including the new front-of-package labeling model. On 27 March 2020, theOfficial Journal of the Federationpublished updates to the norm NOM-051-SCFI/SSA1-2010, stipulating that all food and non-alcoholic beverage packaging and containers must display the approved seals.
The labels implemented are black octagons with white letters, designed to simply inform consumers about high amounts of sugars, energy,trans fats, and saturated fats. Two rectangular warnings were also added, advising against the consumption of products containingcaffeineorsweetenersin children. These labels can appear individually or in groups, which will determine whether the product can include certain persuasive elements, such as toys, rewards, or images of celebrities, fictional characters, or cartoons on the packaging aimed at attracting the attention of minors.Additionally, if the product carries one or more seals, it cannot feature endorsements from medical societies.
In addition to the seals, packaging must includenutrition facts labelsthat specify the exact amount of sugars added during the manufacturing process, as well as the nutritional content expressed in quantities of 100 grams or 100 milliliters.
The governments of the United States, Canada, Switzerland, and the European Union—where the largest multinational food corporations in the world are based—requested through theWorld Trade Organizationthat Mexico postpone the implementation of front labeling. They argued that the measures were "more restrictive than necessary to meet Mexico's legitimate health objectives".The Mexican Consumer Products Industry Council (Consejo Mexicano de la Industria de Productos de Consumo), which represents companies based in Mexico, asked the authorities to eliminate the new front labeling, describing it as confusing and unreliable. Companies such asCoca-Cola,PepsiCo,Jugos del ValleandGrupo Bimborequested the postponement.The latter was able to have some of its products exempted due to its own health strategy.FEMSA, the Coca-Cola producer in Mexico, filed awrit ofamparolawsuit against the labeling of its products.Anotheramparolawsuit filed by the National Confederation of Industrial Chambers in March 2020 was dismissed by the Mexican judiciary.The Interamerican Association for the Protection of Intellectual Property and the Mexican Association for the Protection of Intellectual Property stated that food labeling was unconstitutional and violated international agreements Mexico had signed, including the NAFTA.Civil society researchers highlighted the repeated use of this argument in other countries to block new labeling initiatives.
Among the organizations and entities that celebrated the implementation of the labeling wereUNICEF,theWorld Health Organization, thePan American Health Organization,theNational Human Rights Commission of Mexico, the country's leading public universities (including theNational Autonomous University of Mexico, theNational Polytechnic Instituteand theAutonomous Metropolitan University), as well as the Mexican Secretariats of Economy and Health and the System for the Integral Protection of the Rights of Children and Adolescents.
The World Health Organization awarded SALUD for its efforts in the Prevention and Control of Non-communicable Diseases due to the front-of-package labeling update.
In a survey conducted shortly after the second front-of-package system was officially implemented, Food Navigator found that only 10% of respondents considered the labels.Researchers from the Obesity Data Lab agreed that theCOVID-19 pandemic in the countrywould likely have indirectly affected the results.
Cuauhtémoc Rivera, president of the National Alliance of Small Merchants (Alianza Nacional de Pequeños Comerciantes), mentioned that consumers initially avoided products with seals, but over time, purchases returned to normal levels.
In 2020, Guadalupe López Rodríguez, nutritionist and researcher of theAutonomous University of the State of Hidalgo, commented that, if the Chilean system were used as a model, the labels would have a significant impact on the population during the initial stage of implementation. However, over time consumers would become accustomed to them and would cease to give them the desired importance.Cuauhtémoc Rivera, president of theAlianza Nacional de Pequeños Comerciantes(National Alliance of Small Merchants), mentioned that consumers initially avoided products with seals, but purchases returned to normal levels subsequently.
After one year of implementation, it was found that consumption had decreased in some categories, but there was no significant impact on sales. Jonás Murillo, vice president of the Food, Beverages, and Tobacco Commission of the Confederation of Industrial Chambers, explained that consumers tended to prefer larger versions of products with labels over smaller, healthier alternatives. Additionally, it was noted that in some cases, consumers favored products with more labels over unlabeled ones. Murillo also pointed out that the key issue with the system was its incorrect application. As an example, he compared a salad with dressing and a bottle of soft drink, concluding that despite their different nutritional values, both products had the same number of labels.
After its implementation, 85% of the products received a label.Despite inconclusive results, several companies (especially soft drinks and dairy companies) modified the formulas of certain products to reduce the risk levels. In some cases, the total number of labels on products was reduced, while in others, companies opted to sell an alternate version of the same product that was free of labels.
