Abstract

BACKGROUND

Epidemiologic studies have suggested associations between flavonoid intake and health benefits. Traditional Mediterranean diets consist of a high consumption of plant products rich in flavonoids.

OBJECTIVE

This study estimates dietary flavonoid intake and main food sources in a Mediterranean population (Spanish adults).

DESIGN

The study included 40,683 subjects aged 35 to 64 years from northern and southern regions of Spain who were included in the European Prospective Investigation into Cancer and Nutrition study Spanish cohort. Usual food intake was assessed by personal interviews using a computerized version of a validated diet history method. Expanded US Department of Agriculture databases for the flavonoid, isoflavone, and proanthocyanidin content were used.

RESULTS

The median and mean of total flavonoids were 269.17 and 313.26 mg/day, respectively. The most abundant flavonoid subgroup was proanthocyanidins (60.1%), followed by flavanones (16.9%), flavan-3-ols (10.3%), flavonols (5.9%), anthocyanidins (5.8%), flavones (1.1%), and isoflavones (<0.01%). The main sources of total flavonoid intake were apples (23%), red wine (21%), unspecified fruit (12.8%), and oranges (9.3%).

CONCLUSIONS

These results should be very useful for evaluating the relationships between flavonoid intake and several diseases.

摘要

背景

流行病学研究表明黄酮类化合物的摄入量与健康益处之间存在关联。传统的地中海饮食富含黄酮类化合物的植物产品消费量很高。

目的

本研究估计地中海人群（西班牙成年人）的膳食黄酮类化合物摄入量及其主要食物来源。

设计

该研究纳入了来自西班牙北部和南部地区的40683名年龄在35至64岁之间的受试者，他们被纳入了欧洲癌症与营养前瞻性调查研究的西班牙队列。通过使用经过验证的饮食史方法的计算机化版本进行个人访谈来评估日常食物摄入量。使用了美国农业部扩展的黄酮类化合物、异黄酮和原花青素含量数据库。

结果

总黄酮类化合物的中位数和平均值分别为269.17毫克/天和313.26毫克/天。最丰富的黄酮类亚组是原花青素（60.1%），其次是黄烷酮（16.9%）、黄烷-3-醇（10.3%）、黄酮醇（5.9%）、花青素（5.8%）、黄酮（1.1%）和异黄酮（<0.01%）。总黄酮类化合物摄入的主要来源是苹果（23%）、红酒（21%）、未指明的水果（12.8%）和橙子（9.3%）。
