Cancer incidence is on the rise worldwide and is projected to continue in the next decades¹. It has been established that lifestyle, and nutrition especially, has a crucial role in cancer development, especially in the most common cancers, such as breast, prostate and colorectal². Organisations such as the World Cancer Research Fund and the American Cancer Society have recently released dietary guidelines for the reduction of the risk of developing cancer². Guidelines focus on the role of excess weight and body fat, as well as specific nutrients and dietary patterns in cancer development. Examples of convincing evidence on the role of nutrition in cancer development include red and processed meat with colorectal cancer, and obesity with eleven (11) cancers². In this presentation, all the latest evidence regarding the role of excess weight and obesity, nutrients and dietary patterns will be presented, as well as future research that is warranted to better understand the role of nutrition in cancer development.
