The World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) published a comprehensive report on the relationship between diet, nutrition, and cancer prevention. The report, based on seven years of research, is a significant contribution to public health. It was developed by an expert panel, including 14 researchers, including Mexican Adolfo Chávez, who reviewed over 4,000 scientific articles. The report, consisting of 670 pages, is divided into nine chapters and includes three appendices, a glossary, and a bibliography. It is written in an accessible style, with historical context and clear explanations, making it suitable for both experts and the general public. The first section discusses the relationship between diet and cancer, covering global dietary patterns, cancer mortality, and the biological processes involved in tumor development. The second and third sections present evidence linking cancer to specific dietary patterns and nutrients. The fourth section outlines the implications of these findings for public health policy, nutrition, and diet. The report provides 14 recommendations aimed at reducing cancer incidence and mortality, such as eating a varied plant-based diet, maintaining a healthy weight, consuming fruits and vegetables, limiting alcohol and red meat, and avoiding processed foods. The report concludes that following these recommendations could reduce cancer incidence and mortality by up to 30-40%, preventing three to four million cases annually. Additionally, the seventh edition of "Current Knowledge in Nutrition" by the Organization of American States and the World Health Organization is highlighted as a valuable resource in nutrition science, covering topics from basic to clinical and epidemiological nutrition. It includes chapters on hypertension, osteoporosis, liver disease, and cancer, and is recommended for students, professionals, and researchers in nutrition.The World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) published a comprehensive report on the relationship between diet, nutrition, and cancer prevention.
