Consumption of ultra-processed foods based on the NOVA classification system and association with diet’s quality and clinical outcomes in Crohn’s disease
Introduction: Retrospective studies highlight the negative effect of increased consumption of ultra-processed foods on the Crohn’s disease (CD) risk 1, however studies investigating their consumption during the disease course are lacking. The aim of the present study was to assess the consumption of ultra-processed foods and its association with diet’s quality and clinical outcomes in CD.
Methods Dietary intake and habits were assessed through two non-consecutive 24-hour recalls and a food frequency questionnaire, respectively. Diet’s quality was assessed through the MedDietScore (range 0-55, higher values indicate higher adherence to the Mediterranean dietary pattern) 2,3 and CVD score (range 0-11, higher values indicate higher adherence to dietary guidelines for the prevention of cardiovascular disease) 4. NOVA classification was used to estimate the intake of ultra-processed (NOVA 4) foods 5. Follow-up data were collected at 6, 12 and 24 months [need for intensification/change of biologic agent, start of biologic agent/corticosteroids, disease activity, overall adverse clinical outcome (need for surgery, change of medication, start of biologic agent, administration of corticosteroids, need for hospitalization, cancer)].
Results: 250 adults [54.8% males, aged 41.2±14.1 years, 26.9% obesity] were evaluated. The percentage of NOVA 4 in the daily energy intake was 25.7% (16.8, 41.8%). Higher consumption (4thquartile) of NOVA 4 was associated with higher energy (p=0.033), protein (p=0.023) and carbohydrates (p=0.028) intake; lower MUFA intake (p=0.001), fruit consumption (p=0.007) and CVD score (p=0.031); and higher consumption of red meat (p=0.001), sweets (p=0.009) and soft drinks (p<0.001), compared to the lowest consumption (1st-3rd quartile). No differences were observed between higher NOVA 4 consumption and disease outcomes, after adjustment for age, sex, disease location, disease activity and energy intake at 6, 12 and 24 months.
Conclusions: Consumption of ultra-processed foods had a median contribution to about ¼ of total daily energy intake in this sample of people with CD, which is almost half of that reported in young adults in Greece 6 or the general population in UK, USA and various countries in Europe 7,8. Although higher consumption of ultra-processed foods was associated with lower diet’s quality, it was not associated with adverse clinical outcomes at 6, 12 and 24 months of follow-up.

OC239 - Consumption of ultra-processed foods based on the NOVA classification system and association with diet’s quality and clinical outcomes in Crohn’s disease

Unique to the new Congress (previously the Summer Conference) is that you will have greater opportunity to engage with more nutrition science than ever before. In 2024 the core programme will be delivered by the Irish Section of The Nutrition Society, supported by the Science Committee. The theme of these symposia will be ‘new data – focused approaches and challenges’. Outside of the core programme you will have the chance to hear the latest research from the Society’s partner organisations, universities, the private sector and more, on a diverse range of research.
