Colorectal cancer (CRC) is a disease characterised by the development of malignant tumours in the colon or rectum; it is considered the most common cancer in women, and up to 50% of cases can be prevented with a healthy lifestyle. Nutritional habits are related to its appearance, and the current trend of an increased consumption of ultra-processed foods (UPFs) has led to a surge in the incidence of CRC in recent years. This systematic review aims to evaluate, based on scientific evidence, the role of UPF in the incidence of CRC. The PubMed, Scopus, CINAHL, and Web of Science databases were reviewed, and a total of 24 scientific articles were selected according to the inclusion and exclusion criteria of this review (studies from the past 5 years and observational studies in English). The conclusions of this study point to an association between UPF-based diets and the appearance of CRC, which is promoted by the harmful effects of the consumption of high levels of sugar, fat, red meat, and additives. These dietary habits, coupled with a sedentary lifestyle and obesity, further increase the incidence of CRC.
