Abstract

Cancer is one of the main noncommunicable diseases in terms of health impact. Factors such as a progressively aging population point to future increases in the incidence of cancer on a global level. The elevated number of affected individuals, together with continuous improvements in cancer prevention and therapy, is creating a growing population of cancer survivors, with often inadequately met needs. Lifestyle is a key modulator of cancer risk and of associated morbidity and mortality, and is included in all approaches to the long-term management of cancer. Diet is a principal component of lifestyle, and most of the available evidence is centered on the Mediterranean diet. Our objective was to provide a narrative review of the evidence on the effect of the Mediterranean diet on cancer risk and health threats related to cancer survivorship. For this purpose, we searched the PubMed database for articles published between January 1, 2000, and June 12, 2023. Current data show that the Mediterranean diet is inversely associated with risk, or is risk neutral, for most types of cancer. Tumors of the digestive system have received preferential interest, but studies have also been published on tumors in other organs. The evidence, however, is meager due to the observational nature of most studies, although it is reassuring that benefit is reproduced in studies performed in different populations and environments. Evidence related to cancer survivors is limited by the paucity of studies, yet several findings regarding survival, recurrence, and short- and long-term morbidity suggest a potential role for the Mediterranean diet that warrants further research.
