World Bean Day, celebrated on February 10, reignites the debate on changes in the Brazilian diet and its direct effects on public health. In recent decades, beans have been losing their place on the daily plate, while the rates of chronic diseases associated with poor nutrition are increasing. Recurrent estimates in public debate point to around 57,000 premature deaths per year related to diabetes, in addition to a direct impact of approximately R$ 45 billion on the Unified Health System, adding up the costs of care and indirect effects such as loss of productivity, absences from work, and family complications.
