The integrative review is one of the methodologies used for evidence-based practice which, in this study, had the objective of surveying and synthesizing the evidence available in the literature regarding the dietary risks for colorectal cancer related to the consumption of meat. The search was made using the LILACS, MEDLINE, CINAHL, and COCHRANE Library databases, and six studies considered pertinent to the consumption of meat were found. Meta-analyses showed that there is an association between the consumption of red meat and an increased risk for colorectal cancer from 28% to 35%, whereas processed meats are associated with a rise in risk from 20% to 49%. Evidence shows that the consumption of red meat, processed meat, and total meat consumption are risk factors for developing polyps and colorectal cancer. The search did not yield any studies referring to the consumption of chicken or fish as risk factors.
