为了评估水果和蔬菜摄入量的有效性，使用三种分类方案，因为它与中国女性血浆类胡萝卜素和维生素 C 浓度相关。摄入量是根据采访者进行的食物频率调查问卷计算得出的。对水果和蔬菜、植物组和高营养组进行了评估。将这三种分类方案与问卷完成一周内抽取的血液中的血浆类胡萝卜素和维生素 C 浓度进行比较。中国上海 参与者 (n=2031) 选自参与纺织工人乳房自我检查随机试验的饮食和乳腺疾病病例对照研究的女性 (n=266,064) 水果摄入量显着 (p<0.05)，并且与 α-生育酚、β-隐黄质、番茄红素、 α-胡萝卜素、β-胡萝卜素、棕榈酸视黄酯和维生素 C。水果摄入量与 γ-生育酚和叶黄素 + 玉米黄质浓度呈负相关。蔬菜摄入量与γ-生育酚和β-隐黄质浓度呈显着正相关。每个植物和高营养组也与特定的血浆营养浓度显着相关。水果和蔬菜的摄入量以及大多数血浆营养素浓度与采访季节显着相关。这些结果表明，水果和蔬菜的分组方式提供了不同的血浆营养暴露信息，这在测试和生成与饮食相关的疾病风险的假设时可能是一个重要的考虑因素。在评估报告的摄入量和血浆营养素与疾病结果的关联时，应考虑访谈季节。
To evaluate the validity of fruit and vegetable intake, using three classification schemes, as it relates to plasma carotenoid and vitamin C concentrations among Chinese women. Intakes were calculated from an interviewer-administered food frequency questionnaire. Fruits and vegetables, botanical groups, and high-nutrient groups were evaluated. These three classification schemes were compared with plasma carotenoid and vitamin C concentrations from blood drawn within one week of questionnaire completion. Shanghai, China Participants (n=2031) were drawn from women who participated in a case-control study of diet and breast diseases nested within a randomized trial of breast self-examination among textile workers (n=266,064) Fruit intake was significantly (p<0.05) and positively associated with plasma concentrations of α-tocopherol, β-cryptoxanthin, lycopene, α-carotene, β-carotene, retinyl palmitate, and vitamin C. Fruit intake was inversely associated with γ-tocopherol and lutein+zeaxanthin concentrations. Vegetable consumption was significantly and positively associated with γ-tocopherol, and β-cryptoxanthin concentrations. Each botanical and high-nutrient group was also significantly associated with particular plasma nutrient concentrations. Fruit and vegetable intake and most plasma nutrient concentrations were significantly associated with season of interview. These results suggest that the manner in which fruits and vegetables are grouped provides different plasma nutrient exposure information, which may be an important consideration when testing and generating hypotheses regarding disease risk in relation to diet. Interview season should be considered when evaluating associations of reported intake and plasma nutrients with disease outcomes.
