Neurobiological insights into the effects of ultra-processed food on lipid metabolism and associated mental health conditions: a scoping review

There is a strong association between UPF consumption, disrupted lipid metabolism and increased risk of mental disorder in populations without significant comorbidities. Diets rich in minimally processed foods appear protective. The findings support the potential of public health initiatives aimed at reducing UPF consumption to mitigate the mental health burden. Future studies should focus on mechanistic pathways, UPF and minimally processed food consumption patterns to provide evidence for targeted dietary and policy interventions that improve health outcomes.
