Intake of specific dietary macro- and micronutrients has been implicated in modulating the risk of inflammatory bowel disease (IBD)(Nat Rev Gastroenterol Hepatol 2018;15:525-535). Recent epidemiological and pre-clinical studies have additionally examined the impact of non-nutritional dietary components on IBD. Ultra-processed foods (UPF), as defined by the NOVA classification, are foods of mainly industrial origin, often containing little or no whole foods but many ingredients including food additives such as artificial colors and flavors, stabilizers, emulsifiers, and preservatives(Public Health Nutr 2019;22:936-941). The objective of the study by Narula et al (BMJ 2021;374:n1554) was to examine the association between intake of UPF and the risk of developing IBD.

特定膳食常量和微量营养素的摄入与调节炎症性肠病 (IBD) 的风险有关 (Nat Rev Gastroenterol Hepatol 2018;15:525-535)。最近的流行病学和临床前研究还研究了非营养膳食成分对 IBD 的影响。根据 NOVA 分类的定义，超加工食品 (UPF) 是主要是工业来源的食品，通常含有很少或不含天然食品，但含有许多成分，包括食品添加剂，如人工色素和香料、稳定剂、乳化剂和防腐剂（公共健康营养 2019；22：936-941）。 Narula 等人 (BMJ 2021;374:n1554) 的研究目的是检查 UPF 摄入量与患 IBD 风险之间的关联。
