SUMMARY:

The consumption of ultra-processed foods (UPF) has a negative impact on the quality diet, increasing the risk of health problems and micronutrient deficiencies in the adult population, such as low intake of vitamin A. There is still evidence that studies the impact of this consumption in maternal-child health, being of great importance to systematize this information and explore the relationship between UPF and composition of breast milk. The objective of this study was to analyze the impact of UPF consumption on maternal and child health and on the vitamin A composition of breast milk. The work was divided into two stages: in the first stage, a systematic review was performed, registered in the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42021236633), following PRISMA, in PubMed/Medline, Scopus, Web of Science, Scielo and CAPES directory. Eligibility criteria were: a) food consumption by the NOVA classification, b) health outcome (nutritional and diseases) associated with UPF consumption; and c) observational studies with the maternal-infant population (pregnant women, lactating women and infants/children). All data were analyzed and extracted into a structured spreadsheet by two independent reviewers. The methodological quality of the studies was assessed using the Newcastle-Ottawa Scale. In the second stage of this work, a cross-sectional study is being carried out with lactating women treated at health units in Natal-RN. Milk collection and 24-hour recall are performed in two moments: 1st, with 30 to 120 days after delivery and the 2nd, with 30 to 60 days after the 1st. The concentration of retinol in milk was analyzed by High Performance Liquid Chromatography. The results of the systematic review retrieved 7,801 studies and 15 met the eligibility criteria. Most were cohort studies (n=8; 53%), had children as a population (n=9; 60%) and only one study evaluated UPF consumption in lactating women. A greater participation of UPF in the diet has been associated with increased weight gain, adiposity, excess weight, early weaning, poorer diet quality, disease and plastic consumption. Only one of the included studies did not show high methodological quality. In the partial data of the second stage of this study, of the 38 lactating women evaluated, 1.21 μmol/L (95%CI 0.99-1.43) of retinol in mature milk was found, with 23% (n=9) of indication of vitamin A deficiency (≤ 1.05 μmol/L). Theoretically estimating the intake of milk analyzed according to the recommended daily volume (780 mL/day), it was observed that 78.9% of the milks would not reach the recommended intake of vitamin A (400 μgRE/day), with 261 μgRE/day. The studies found in the systematic review showed a negative impact of UPF on maternal and child health, with repercussions on nutritional indicators, diseases and toxicity. Additionally, it demonstrated the need for further studies in the lactation phase, justifying the importance of the second stage of this work. This, even in progress, suggests an inadequacy of vitamin A in breast milk in the samples analyzed, and the final analyzes will make it possible to understand whether the consumption of UPF can be decisive for this situation.
