La consommation d’aliments issus de l’agriculture biologique réduit-elle l’incidence du cancer ? : une revue systématique de la littérature

Abstract : Background: The links between diet and cancer are now established. The literature tends to observe that environmental exposure to pesticides is carcinogenic and that we are exposed to it daily through food. Studies show less exposure to pesticides when eating organic food. Since consumers eat organic food out of belief that they can improve their health, we wanted to know if this consumption could reduce the incidence of cancer. Methods: We carried out an exhaustive search of the literature in 8 search engines including PUBMED. All types of studies, descriptive or analytical, were sought. Results: We reviewed 974 publications and two of which met the inclusion criteria. A first study observed a reduction in the incidence of all cancers combined among organic consumers (RR 0.75), while the second study showed no difference. Results for breast cancer were inconsistent (RR 0.91 vs RR 0.66). The NHL incidence was significantly reduced among organic consumers in both studies (RR 0,79 and 0,14). Conclusions: The search results do not allow us to conclude. The aim of this thesis was to expose a major lack of data. It is necessary to promote further studies analysing this link. In the meantime, we must continue to encourage our patients to eat conventional fruits and vegetables if they cannot access organic food, and to follow the PNNS4 recommendations (physical activity, food balance).
