Ultra-processed foods (UPFs) are industrially formulated products that contain synthetic ingredients but minimal whole-food components. Diets high in UPFs are associated with increased risk of immune dysregulation-linked diseases such as inflammatory bowel disease and potentially autoimmune disease. Several putative mechanisms have been proposed to explain this association, and these need urgent research attention. This Comment discusses the potential effects of ultra-processed foods (UPFs) on the immune system independently of obesity, by which UPFs might dysregulate the balance between the gut microbiota and immune cells.

超加工食品：增加炎症和免疫失调的风险？


超加工食品 (UPF) 是工业配制的产品，含有合成成分，但全食品成分极少。富含 UPF 的饮食会增加患免疫失调相关疾病的风险，例如炎症性肠病和潜在的自身免疫性疾病。已经提出了几种假定的机制来解释这种关联，这些需要迫切的研究关注。这篇评论讨论了超加工食品 (UPF) 对免疫系统的潜在影响，与肥胖无关，UPF 可能会失调肠道微生物群和免疫细胞之间的平衡。
