[Nutrition as an epigenetic factor in develops of cancer].

Introduction: the incidence and prevalence of cancer disease is growing in the last years, cancer is currently the second cause of death in Spain. For years nutrition has been linked with cancer as etiologic factor, but evidence levels are poorer than expected. With science advances, epigenetic have became a large field in nutrition to try to find solid relationships between nutrition and cancer development. Objectives: this paper reviews the scientific evidence and the possible links between cancer etiology and nutrition. Methods: bibliographic review and selection of the most relevant studies found. Results and discussion: there is a relationship between nutrition and epigenetic modifications that can cause or prevent different types of cancer, by knowing those alterations we will be able to perform some primary prevention strategies trying to reduce cancer incidence. There is evidence that folates, polyphenols, selenium, isothiocyanates and Vitamin D, among others, can be related with cancer development. With a growing knowledge on the relationship between cancer, nutrition and epigenetics we will have the opportunity to use it as an important protective factor for the general population.
