Deciphering the impact of dietary habits and behavioral patterns on colorectal cancer.

Abstract

Colorectal cancer (CRC) is a malignant tumor that originates from the epithelial cells of the colon and rectum. Global epidemiological data shows that in 2020, the incidence and mortality rate of CRC ranked third and second, respectively, posing a serious threat to people's health and lives. The factors influencing CRC are numerous and can be broadly categorized as modifiable and non-modifiable based on whether they can be managed or intervened upon. Non-modifiable factors include age, gender, family history, among others. Among the modifiable factors, dietary habits and behavioral practices are the main intervention measures that people can take to prevent CRC. Numerous studies indicate that a high intake of red and processed meats, fats, as well as habits such as smoking, alcohol consumption, and prolonged sitting, increase the risk of developing CRC. Conversely, consuming ample vegetables, fruits, high dietary fiber, and engaging in moderate regular exercise may reduce the risk of CRC. This article primarily discusses the impact of dietary habits and behavioral practices on the occurrence and development of CRC, along with possible mechanisms, laying the foundation and providing direction for the prevention and control of CRC occurrence and development.
