Research progress on dietary patterns and etiology for Cancer

In recent years, the incidence of malignant tumors in China has been increasing steadily. Advancing primary prevention measures for malignant tumors is an effective strategy to curb this trend. Diet is considered a modifiable and shared risk factor for various malignant tumors. Studying dietary patterns, which take into account the interactions between foods and nutrients, has practical implications for cancer prevention. This study provides an overview of dietary pattern extraction methods and focuses on systematic reviews summarizing the research findings on the association between dietary patterns and malignant tumors in the digestive system, respiratory system, and genitourinary system. The potential mechanisms underlying these associations are also discussed. This review serves as a scientific basis for future research in this field.
