肿瘤是严重威胁人类生命健康的恶性消耗性疾病,其发生率和死亡率逐年增加。 影响肿瘤发生、发展的因素复 杂,其中饮食作为主要的可预防因素,其潜在作用不容忽视。 饮食具有促炎特性和抗炎特性,不合理的膳食所引起的机体长 期慢性炎症与肿瘤密切相关,并降低了肿瘤的治疗效果。 科学合理的膳食可改善机体慢性炎症状态,改变肿瘤微环境,从而 达到预防肿瘤发生和促进患者康复的作用。 能够客观评估膳食对机体的炎症效应,无论对科学研究还是临床防治都具有积 极意义。 膳食炎症指数(DII)是一种评估个人膳食炎症潜能的新方法,具有客观、方便、可重现的特点,近些年较多研究探索 了 DII 与多种肿瘤的关系。 本共识以 DII 为研究工具,总结了促炎性饮食与各类肿瘤的发病关系,并提出肿瘤防治的抗炎性 膳食模式,从抗炎饮食角度为肿瘤患者提供预防和辅助治疗策略。 提倡科学健康的饮食行为,鼓励居民调整膳食结构,为肿 瘤患者的营养治疗提供新策略。

Tumor is a kind of malignant wasting disease which seriously threatens human life and health. Its incidence and mortality are increasing year by year. There are complex factors affecting the occurrence and development of tumors among which diet is the main preventable factor and its potential role cannot be ignored. Diet has both pro - inflammatory and anti - inflammatory properties. Long-term chronic inflammation caused by irrational diet is closely related to tumor and reduces the therapeutic effect of tumor. Scientific and reasonable diet can improve the chronic inflammation state of the body change the tumor microenvironment so as to achieve the role of preventing tumor occurrence and promoting the recovery of patients. It is of positive significance for scientific research and clinical prevention and treatment to objectively evaluate the inflammatory effect of diet on the body. Dietary inflammation index DII is a new method to evaluate individual dietary inflammatory potential which is objective convenient and reproducible. In recent years many studies have explored the relationship between DII and various tumors. This consensus using DII as the research tool summarizes the relationship between pro - inflammatory diet and the incidence of various types of tumors and proposes an anti-inflammatory dietary model for cancer prevention and treatment so as to provide prevention and adjuvant treatment strategies for cancer patients from the perspective of anti-inflammatory diet. To promote scientific and healthy eating behavior encourage residents to adjust the dietary structure and provide a new strategy for nutritional treatment of cancer patients.
