Apart from individual genetic background, unhealthy lifestyle and diet, etc., nutrition also plays an important role in the occurrence and progression of gastrointestinal tumors. Although some patients with gastrointestinal tumors can be satisfied with the traditional nutritional support, it is apparently inadequate for the systemic management of all patients. Precision nutrition support, also known as personalized nutrition support, refers to safe and efficient individualized nutrition intervention based on the investigation of individual genetic background, life characteristics, metabolic indicators, intestinal microbial characteristics, and physiological status factors through big data analysis for the prevention and treatment of chronic diseases. This review focuses on the relationship between nutrition and gastrointestinal tumors and discusses the progress of precision nutrition support therapy in the gastrointestinal tumors. Based on this, we hope to achieve effective personalized intervention protocols, and improve the clinical outcome and the overall oncology care of gastrointestinal tumors.
胃肠肿瘤的发生和进展多与个体遗传背景、不良生活方式以及不合理饮食等有关，营养也在其中发挥重要作用。传统的营养支持治疗方式，虽然能够满足部分胃肠肿瘤患者的营养需求，但显然无法适应新形势下胃肠肿瘤的整体治疗需要。精准营养治疗又称个性化营养治疗，是指在考察个体遗传背景、生活特征、代谢指标、肠道微生物特征和生理状态因素的基础上，通过大数据分析，进行安全、高效的个体化营养干预，以达到预防和治疗慢性疾病的目的。本文围绕营养和胃肠肿瘤的关系，探讨精准营养治疗在胃肠肿瘤中的进展，期望实现有效的个性化干预方案，改善胃肠肿瘤患者的临床结局，提升胃肠肿瘤的整体治疗水平。.
