Nutrition plays a key role in supporting the human immune system and reducing the risk of infections. However, there is limited evidence exploring the relationship between diet and the risk of COVID-19. This study aimed to assess the associations between consumption of ultra-processed foods (UPF) and COVID-19 risk.
The study concluded that higher UPF consumption in the diet was associated with a significantly increased risk of COVID-19 in this large prospective cohort. This association could be partly mediated by the effect of UPF consumption on BMI. Our fndings suggest that public health interventions to improve nutrition and poor metabolic health may be important for reducing the burden of the COVID-19 pandemic. Further evidence on the underlying mechanism is needed
