The aim of this study was to estimate the dietary intake and major food sources of polyphenols in the Mediterranean healthy Eating, Aging and Lifestyles (MEAL) study cohort. A total of 1937 individuals (18 + y) of urban population of Catania, Italy, completed a validated 110-item food frequency questionnaire; Phenol-Explorer database was used to estimate polyphenol intake. Mean intake of polyphenols was 663.7 mg/d; the most abundant classes were phenolic acids (362.7 mg/d) and flavonoids (258.7 mg/d). The main dietary sources of total polyphenols were nuts, followed by tea and coffee as source of flavanols and hydroxycinnamic acids, respectively, fruits (i.e. cherries were sources of anthocyanins and citrus fruits of flavanones) and vegetables (i.e. artichokes and olives were sources of flavones and spinach and beans of flavonols); chocolate, red wine and pasta contributed to flavanols and tyrosols, respectively. These findings will be useful to assess the potential benefits of foods with high polyphenol content.
本研究旨在评估地中海健康饮食、衰老与生活方式（MEAL）研究队列中多酚的膳食摄入量及主要食物来源。意大利卡塔尼亚市共有1937名18岁及以上的城市居民完成了一份经过验证的包含110个条目的食物频率问卷；使用酚类物质探索者数据库来估计多酚摄入量。多酚的平均摄入量为663.7毫克/天；含量最丰富的类别是酚酸（362.7毫克/天）和黄酮类化合物（258.7毫克/天）。总多酚的主要膳食来源是坚果，其次是茶（作为黄烷醇的来源）和咖啡（作为羟基肉桂酸的来源）、水果（如樱桃是花青素的来源，柑橘类水果是黄烷酮的来源）和蔬菜（如洋蓟和橄榄是黄酮的来源，菠菜和豆类是黄酮醇的来源）；巧克力、红酒和面食分别提供黄烷醇和酪醇。这些发现将有助于评估高多酚含量食物的潜在益处。
