Résumé

Aim: Nutrition is part of behavorial factors on which it is possible to act to reduce cancer risk. It is estimated that 20-25% of cancers can be attributed to nutritional factors. To better inform health professionals and the public on nutritional factors that increase or decrease the risk of cancer, the French National Cancer Institute in connection with the NACRe network of nutrition researchers coordinated a collective expertise, which resulted in a scientific report, a general public document and a publication in an international journal. Strategy/Tactics: To update the levels of evidence of the relationships between 10 nutritional factors considered relevant for the French population and cancer risk, the scientific literature published from 2006 to 2014 was reviewed by an expert group. Data from more than 130 meta-analyses, pooled analyses and intervention trials were examined. Nearly 150 relationships between nutritional factors and cancer at various sites were evaluated. Outcomes: According to the evidence graded as convincing or probable, nutritional factors were divided in two groups. Factors that increase the risk of cancer are alcoholic beverages, overweight and obesity, red meat and processed meat, salt and salted foods and beta-carotene supplements. Factors that decrease the risk of cancer are physical activity, fruits and vegetables, dietary fiber, dairy products and breastfeeding. Research effort must be maintained on numerous associations whose evidence is still considered as “suggestive” or “not conclusive”. What was learned: For the French population, three main nutritional objectives should be attained to improve cancer prevention at the population and individual level: reduce the consumption of alcoholic beverages, have a balanced and diversified diet and be physically active; also promote breastfeeding among pregnant women. Health professionals are encouraged to relay these objectives to their patients.
