It is unknown if the consumption of ultra-processed food (UPF) increase the risk of asthma.
A new study published in Pediatric Allergy and Immunology investigated whether UPF consumption during childhood was associated with wheeze, asthma and severe asthma in adolescence.
In this study, 2,190, 11-year-old children without asthma at the age of 6 years, were selected from the 2004 Pelotas Birth Cohort Study. Consumption of UPF was assessed by Food Frequency Questionnaires at 6- and 11-year follow-ups. Wheeze, asthma and severe asthma data were assessed at 11-year follow-up. Here, foods were classified according to the processing degree in ultra-processed food.
The results showed that the cumulative incidence of wheeze and asthma between 6 and 11 years were 12.7% and 23.2%, respectively. On comparing children in the highest and the lowest quintile of UPF consumption at the age of 6 years, no association with wheeze, asthma or severe asthma were found in early adolescence. Additionally, when comparing adolescents in the highest and lowest quintile of UPF consumption at 11years, there was no association with wheeze, asthma or severe asthma.
Hence, the findings indicated that UPF consumption during childhood or adolescence is not associated with asthma or wheeze among adolescents.
