The Manual presented in this publication offers health researchers and advisors an instrument named “27 UPF (ultra-processed foods) Categories Tracker”; validated in Quito for its use in Ecuador in research on food consumption, either in specific studies or in national surveys, to which a module can be added that takes approximately ten minutes to apply. This Tracker will allow us to quickly and easily determine the caloric content of ultraprocessed products in the population’s diet, which is relevant information for designing local or national policies and programs that ensure healthy nutrition.
