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.
整合性综述是循证实践所采用的方法之一。在本研究中，其目的是调查和综合文献中有关肉类消费与结直肠癌饮食风险的现有证据。通过使用拉丁美洲和加勒比地区健康科学数据库（LILACS）、医学文献数据库（MEDLINE）、护理学与健康领域数据库（CINAHL）以及考克兰图书馆数据库进行检索，发现了六项与肉类消费相关的研究。荟萃分析表明，红肉消费与结直肠癌风险增加之间存在关联，风险增幅为28%至35%，而加工肉类与风险上升之间的关联度为20%至49%。有证据表明，红肉、加工肉类以及肉类总消费量是引发息肉和结直肠癌的风险因素。检索未发现任何将鸡肉或鱼肉消费视为风险因素的研究。
