People need to choose from a wide range of foods, and in addition to availability and accessibility, people's values and preferences largely determine their daily food choices. Given the potential adverse health consequences of red and processed meat and the limited knowledge on individuals' health-related values and preferences on the topic, such data would be useful in the development of recommendations regarding meat consumption. We will perform a cross-sectional mixed methods study. The study population will consist of adult omnivores currently consuming a minimum of three weekly servings of either unprocessed red meat or processed meat. We will explore participants' willingness to stop or reduce their unprocessed red meat, or their processed meat consumption through a direct-choice exercise. This exercise will consist of presenting a scenario tailored to each individual's average weekly consumption. That is, based on a systematic review and meta-analysis of the best estimate of the risk reduction in overall cancer incidence and cancer mortality, we will ask participants if they would stop their consumption, and/or reduce their average consumption. We will also present the corresponding certainty of the evidence for the potential risk reductions. Finally, we will measure their meat consumption three months after the interview and determine if they have made any changes to their average consumption. The research protocol was approved by the ethics committees in Canada (Research Ethics Board, Dalhousie University), Spain (Comitè Ètic d'Investigació Clínica de l'IDIAP Jordi Gol), Poland (The Bioethics Committee of the Jagiellonian University), and Brazil (National Research Ethics Commission). The study is based on voluntary participation and informed written consent. Results from this project will be disseminated through publications and presentations.
人们需要从广泛的食物中进行选择，除了可用性和可及性之外，人们的价值观和偏好在很大程度上决定了他们的日常食物选择。鉴于红色和加工肉类可能对健康造成不利影响，以及人们在健康相关价值观和偏好方面对这一主题的了解有限，此类数据将有助于制定关于肉类消费的建议。
我们将进行一项横断面混合方法研究。研究人群将包括目前每周至少食用三份未经加工的红色肉类或加工肉类的成年杂食者。我们将通过直接选择练习探索参与者停止或减少其未经加工的红色肉类或加工肉类消费的意愿。该练习将包括呈现一个针对每个个体平均每周消费情况量身定制的情景。也就是说，基于对总体癌症发病率和癌症死亡率降低风险的最佳估计的系统评价和荟萃分析，我们将询问参与者是否会停止食用，以及/或减少其平均食用量。我们还将介绍潜在风险降低的证据确定性。最后，我们将在访谈后三个月测量他们的肉类消费，并确定他们是否对平均消费做出了任何改变。
该研究方案已获得加拿大（达尔豪斯大学研究伦理委员会）、西班牙（IDIAP Jordi Gol 临床研究伦理委员会）、波兰（雅盖隆大学生物伦理委员会）和巴西（国家伦理研究委员会）的伦理委员会批准。该研究基于自愿参与和书面知情同意。该项目的结果将通过出版物和演讲进行传播。
