Two years after the beginning of the pandemic caused by the Sars-Cov-2 virus, research on the pathogenesis of its infection has advanced considerably, certain general factors, such as comorbidities, have been highlighted, and causal factors specific to the urban setting have been identified. The aim of this article is to provide qualitative and quantitative elements that indicate the relationship between the consumption of ultra-processed foods (upfs) poor in micronutrients and the pathogenesis of Sars-Cov-2 infection in Mexico City (cdmx), in an investigation of the causes of this problem. A qualitative methodology was followed, based on documentary search and content analysis. The results showed that the high consumption of upfs in cdmx is problematic, as these foods contain few of the micronutrients essential for the proper functioning of the immune system and to cope with diseases such as covid-19. Although the existing data to date do not allow us to establish a direct causality between covid-19 and consumption of upfs in the cdmx, they do indicate latent dangers, which merit investigating their effects and rethinking public and health policies.
