Nutrition studies link parental diets to newborn health in Brazil

Recent studies in Brazil are highlighting the complex factors influencing nutrition during pregnancy and its impact on newborn health. Research from the University of São Paulo (USP) suggests an association between parental consumption of ultra-processed foods and the physical measurements of infants at birth, such as weight and adiposity index.

The USP study emphasizes the importance of paternal diet, noting that men's nutritional habits at least three months before conception may affect sperm quality and fetal development through epigenetic pathways. In the study, ultra-processed foods accounted for approximately 30% of energy intake for men and 26% for women.

Complementary research from the Federal University of Paraná (UFPR), based on data from the Unified Health System (SUS) in Colombo, identifies socio-demographic vulnerabilities. The study indicates that lower income restricts access to fresh produce, while younger pregnant women are more prone to consuming foods high in sugar and fat. Additionally, the research noted that nearly 80% of adolescent pregnant women and first-time mothers consume meals while watching screens, a habit that can delay satiety perception.
