The percentage of daily energy provided by pro-cessed and ultra-processed products was 42.6± 8.5 at preschool age and 49.2± 9.5 at schoolage, on average. In terms of energy intake, the main products consumed were breads, savourysnacks, cookies, candy and other sweets in both age groups. Ultra-processed product consump-tion at preschool age was a predictor of a higher increase in total cholesterol (_ = 0.430;P=0.046) and LDL cholesterol (_ = 0.369;P=0.047) from preschool to school age.Conclusion: Our data suggest that early ultra-processed product consumption played a role in altering lipoprotein profiles in children from a low-income community in Brazil. These results are important to understanding the role of food processing and the early dietary determinants of cardiovascular disease.
