This has led to a need to monitor exposure to these compounds in human populations and to determine which components of a mixed diet contribute to the exposure. Typically, urinary isoflavonoid excretion is associated with soy consumption and that of lignans is associated with whole grains. However, other plant foods are known to contain phytoestrogen precursors. The purpose of this study was to examine the association between urinary isoflavonoid and lignan excretion and intakes of vegetables and fruits (V&amp;F). Isoflavonoids (genistein, daidzein, O-desmethylangolensin, and equol) and lignans (enterolactone, enterodiol, and matairesinol) were measured in urine collected for 3 days from 49 male and 49 female volunteers (age, 18-37 years) reporting a wide range of habitual V&amp;F intakes. Dietary intakes were assessed using 5-day diet records and a food frequency questionnaire. V&amp;F groupings (total V&amp;F, total V, total F, soyfoods, and V&amp;F grouped by botanical families) were used to assess the relationship between V&amp;F intake and urinary isoflavonoid and lignan excretion. Pearson correlations were performed. Intake of soyfoods was correlated significantly with urinary genistein (r = 0.40; P = 0.0001), O-desmethylangolensin (r = 0.37; P = 0.0002), daidzein (r = 0.34; P = 0.0007), and the sum of isoflavonoids (r = 0.39; P = 0.0001). There was no association between equol excretion and soy intake or between the isoflavonoids and any other V&amp;F groupings. In addition, isoflavonoid excretion was correlated positively with intake of high-fat and processed meats, particularly among men who did not consume soy. This suggests that, even in the United States, on a Western diet, soyfoods are the primary contributors to isoflavone intake; however, additional \u00ab\u00a0\u00a0\u00bbhidden sources\u00a0\u00bb\u00a0\u00bb of soy may also contribute to exposure. In contrast, a variety of fiber-containing foods contributed to lignan excretion; the sum of the urinary lignans, enterodiol, enterolactone, and matairesinol, was associated with intake of total F (r = 0.27; P = 0.008), total V&amp;F (r = 0.25; P = 0.01), soyfoods (r = 0.28; P = 0.006), and dietary fiber (r 0.36; P = 0.0003). Overall, urinary phytoestrogens (isoflavonoids + lignans) were significantly higher in \u00ab\u00a0\u00a0\u00bbhigh\u00a0\u00bb\u00a0\u00bb compared with \u00ab\u00a0\u00a0\u00bblow\u00a0\u00bb\u00a0\u00bb V&amp;F consumers. Compared with the \u00ab\u00a0\u00a0\u00bblow\u00a0\u00bb\u00a0\u00bb V&amp;F group, the \u00ab\u00a0\u00a0\u00bbhigh\u00a0\u00bb\u00a0\u00bb group consumed diets that were, on average, higher in fiber and carbohydrate and soyfoods and lower in fat; thus, the urinary phytoestrogens may also be a useful marker of healthier dietary patterns.\u00a0\u00bb<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-58104","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"LAMPE JW,FRED HUTCHINSON
