Il existe une corrélation inverse entre la consommation de denrées d'origine végétale et l'incidence des cancers et des pathologies chroniques. Ces vertus sont attribuées, entre autres, à des nutriments d'origine végétale ou phytonutriments. Ces métabolites secondaires se divisent en quatre classes selon leurs structures chimiques. Ils sont doués de plusieurs propriétés biologiques et pharmacologiques expliquant leurs bienfaits sur la santé de l'homme. Certains d'entre eux sont actifs par leur pouvoir antioxydant, d'autres participent à la détoxification enzymatique des substances cancérigènes présentes dans l'organisme. Du fait de la diversité de leurs propriétés biologiques et pharmacologiques, les phytonutriments sont intéressants en prophylaxie des cancers et de différentes maladies, notamment cardiovasculaires, ophtalmiques et inflammatoires.
Phytonutriments and their impact on healthAbstract: A reverse correlation was noticed between the intake of plant based food and the incidence of cancer and chronic diseases. These health benefits are partly owed to plant bioactive components called phytonutrients. These secondary metabolites are divided into four classes according to their chemical structures. They have many biological and pharmacological properties which explain their benefits on the human health. These health-promoting properties are due to their high antioxidant capacity. They also exert their beneficial impact through enhancing the enzymatic detoxification pathways. Owing to their diverse effects, the phytonutrients are interesting in cancer prevention and other disorders such as cardiovascular, ophthalmic and inflammatory diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
