The comings and goings of the design of the healthy eating policy in Peru: a comparative analysis of its regulatory documents.

The sale of ultra-processed products has increased in Latin America in recent years, as well as the prevalence of overweight and obesity. In Peru, Law No. 30021 passed in an attempt to reduce overweight and obesity in children and adolescents; however, the development of this law was characterized by constant modifications to the documents prepared in this regard. This article aims to identify essential modifications in the documents elaborated by the Government and the Congress within the timeframe of Law No. 30021, particularly those regarding the regulation of food and non-alcoholic beverage advertising, advertising warnings and technical parameters of critical nutrients. The lack of timely scientific evidence, the opposition by the food industry and the lack of political consensus were the main reasons for the detected modifications, which shows the dynamism during the development of this policy.
