更多地坚持传统地中海（MED）饮食与降低患慢性病的风险有关。这种饮食模式是基于对富含类黄酮的植物产品的更高消费。我们比较了参与EPIC研究的MED和非MED国家之间的总黄酮饮食摄入量，食物来源和各种生活方式因素。使用标准化24小时饮食回忆软件（EPIC-Soft（R））对1992年至2000年期间在26个研究中心招募的35628名年龄在35-74岁的受试者的黄嘌呤摄入量及其食物来源进行了估计。利用美国农业部和酚探索者数据库的分析数据，编制了一个关于类黄酮的特设食物成分数据库。此外，它被扩展到包括使用配方，估计缺失值和黄酮保留因子。非地中海国家（373.7 mg/d）和地中海国家（370.2 mg/d）之间的总黄酮平均摄入量无显著差异。在非地中海地区，主要贡献者是原花青素（48.2%）和黄烷-3-醇单体（24.9%），主要食物来源是茶（25.7%）和水果（32.8%）。在地中海地区，原花青素（59.0%）是迄今为止最丰富的贡献者，水果（55.1%），葡萄酒（16.7%）和茶（6.8%）是主要的食物来源。目前的研究表明，总膳食黄酮摄入量的相似结果，但显着差异，类黄酮类摄入量，食物来源和一些特征之间的MED和非MED国家。在研究类黄酮摄入量与慢性疾病之间的关系时，应考虑这些差异。
A greater adherence to the traditional Mediterranean (MED) diet is associated with a reduced risk of developing chronic diseases. This dietary pattern is based on higher consumption of plant products that are rich in flavonoids. We compared the total flavonoid dietary intakes, their food sources and various lifestyle factors between MED and non-MED countries participating in the EPIC study. Flavonoid intakes and their food sources for 35 628 subjects, aged 35-74 years and recruited between 1992 and 2000, in twenty-six study centres were estimated using standardised 24 h dietary recall software (EPIC-Soft (R)). An ad hoc food composition database on flavonoids was compiled using analytical data from the United States Department of Agriculture and Phenol-Explorer databases. Moreover, it was expanded to include using recipes, estimations of missing values and flavonoid retention factors. No significant differences in total flavonoid mean intake between non-MED countries (373.7 mg/d) and MED countries (370.2 mg/d) were observed. In the non-MED region, the main contributors were proanthocyanidins (48.2 %) and flavan-3-ol monomers (24.9 %) and the principal food sources were tea (25.7 %) and fruits (32.8 %). In the MED region, proanthocyanidins (59.0 %) were by far the most abundant contributor and fruits (55.1 %), wines (16.7 %) and tea (6.8 %) were the main food sources. The present study shows similar results for total dietary flavonoid intakes, but significant differences in flavonoid class intakes, food sources and some characteristics between MED and non-MED countries. These differences should be considered in studies about the relationships between flavonoid intake and chronic diseases.
