几十年来的大量研究表明，遵循地中海饮食（MedDiet）可以降低心血管疾病和癌症的风险，并改善认知健康。然而，用于评价和定义MedDiet的方法之间存在不一致性。通过文献回顾，我们的目的是定量定义的食物组和营养素的MedDiet。检索数据库PubMed、MEDLINE、Science Direct、Academic Search Premier和南澳大学图书馆目录。如果文章以以下至少两种方式定义MedDiet，则将其纳入：（1）一般描述性定义;（2）饮食金字塔/关键食物的份量;（3）关键食物/食物组的克数;以及（4）营养素和类黄酮含量。记录关键食物的数量和营养素含量，并计算平均值。MedDiet每天包含3至9份蔬菜，半至2份水果，1至13份谷物和多达8份橄榄油。它含有约9300千焦，37%的总脂肪，18%的单不饱和和9%的饱和，和33克纤维每天。我们的研究结果提供了一个确定的营养成分和范围的服务MedDiet的基础上，过去和现在的文献。更详细的研究报告可以进一步完善定义。
Numerous studies over several decades suggest that following the Mediterranean diet (MedDiet) can reduce the risk of cardiovascular disease and cancer, and improve cognitive health. However, there are inconsistencies among methods used for evaluating and defining the MedDiet. Through a review of the literature, we aimed to quantitatively define the MedDiet by food groups and nutrients. Databases PubMed, MEDLINE, Science Direct, Academic Search Premier and the University of South Australia Library Catalogue were searched. Articles were included if they defined the MedDiet in at least two of the following ways: (1) general descriptive definitions; (2) diet pyramids/numbers of servings of key foods; (3) grams of key foods/food groups; and (4) nutrient and flavonoid content. Quantity of key foods and nutrient content was recorded and the mean was calculated. The MedDiet contained three to nine serves of vegetables, half to two serves of fruit, one to 13 serves of cereals and up to eight serves of olive oil daily. It contained approximately 9300 kJ, 37% as total fat, 18% as monounsaturated and 9% as saturated, and 33 g of fibre per day. Our results provide a defined nutrient content and range of servings for the MedDiet based on past and current literature. More detailed reporting amongst studies could refine the definition further.
