Reacción a "Reaction to study linking processed food consumption to 57,000 premature deaths in Brazil"

The study is original and based on a very large sample. The main problem is that the authors have not included very important confounding factors such as social class, and this factor may generate residual or unaccounted for confounding in the study. 

The study has important implications because many deaths could be prevented just by changing the dietary habits of the general population, but further studies confirming these results and taking into account confounding factors such as the standard of living of the population are lacking.
