In 2007, the World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) issued recommendations on diet, physical activity, and weight management for cancer prevention on the basis of the most comprehensive collection of available evidence.
In a study that included 378,864 participants, from 9 European countries, after a median follow-up time of 12.8 y, 23,828 deaths were identified. Participants within the highest category of the WCRF/AICR score, that means those participants that actually followed the guidelines had a 34% lower hazard of death (95% CI: 0.59, 0.75) compared with participants who did not follow these guidelines. This trend was observed in all 9 countries. The WCRF/AICR score was also significantly associated with a lower hazard of dying from cancer, circulatory disease, and respiratory disease. The researchers concluded that following WCRF/AICR recommendations could significantly increase longevity.
