 This study found that the greater consumption of ultra-processed foods in Brazil is associated with a decrease in the quality of the dietary nutrition profile. This includes increased energy density, higher overall fat content, higher saturated and trans fat, lower levels of fiber, protein, sodium and potassium, and higher levels of free sugars. Additionally, the study found that the consumption of ultra-processed foods leads to a general deterioration in the dietary nutrition profile when compared to the consumption of processed foods. The study concluded that the replacement of traditional meals, based on natural or minimally processed foods, with ultra-processed foods is leading to a decrease in the quality of the dietary nutrition profile in Brazil.
