Increased fruit and vegetable consumption has become a health priority in many countries. Therefore, data investigating the influence of different types of fruits and vegetables on serum antioxidant levels would be useful. The objective of the study was to assess the relationship between fruit and vegetable consumption and vitamin serum antioxidant concentrations. Specific fruit and vegetable groups are evaluated. A total of 3521 subjects (1487 men and 2034 women), aged 35-60 years, participating in the SU.VI.MAX cohort were included in this study. Blood samples of participants were analysed for beta-carotene, vitamin C and alpha-tocopherol. Each subject had completed at least six dietary records during the first 2 years of the study. It was found that women had higher mean beta-carotene and vitamin C serum concentrations than men, but lower alpha-tocopherol serum concentrations. Serum beta-carotene and vitamin C concentrations were positively correlated with consumption of both fruit and vegetables, as well as with most of the fruit and vegetable groups tested. These relationships persisted after adjustment for confounding factors. Regression analysis showed a linear dose-response relationship. Root vegetables and citrus fruits were particularly associated with beta-carotene serum status as were citrus fruits for vitamin C. Fruit and vegetable consumption was either not or weakly associated with alpha-tocopherol serum concentrations. These results describe antioxidant serum concentrations according to fruit and vegetable consumption in a large sample and support the findings of previous studies involving a more limited number of subjects.
增加水果和蔬菜的摄入量已成为许多国家的一项健康优先事项。因此，研究不同类型的水果和蔬菜对血清抗氧化剂水平影响的数据将很有用。本研究的目的是评估水果和蔬菜摄入量与血清维生素抗氧化剂浓度之间的关系。对特定的水果和蔬菜类别进行了评估。共有3521名年龄在35至60岁之间的受试者（1487名男性和2034名女性）参与了SU.VI.MAX队列研究并被纳入本研究。对参与者的血样进行了β-胡萝卜素、维生素C和α-生育酚的分析。在研究的前两年中，每个受试者至少完成了六次饮食记录。结果发现，女性的血清β-胡萝卜素和维生素C平均浓度高于男性，但血清α-生育酚浓度低于男性。血清β-胡萝卜素和维生素C浓度与水果和蔬菜的摄入量以及所测试的大多数水果和蔬菜类别均呈正相关。在对混杂因素进行调整后，这些关系依然存在。回归分析显示出线性剂量反应关系。根茎类蔬菜和柑橘类水果与血清β-胡萝卜素水平尤其相关，柑橘类水果与维生素C水平也尤其相关。水果和蔬菜的摄入量与血清α-生育酚浓度要么没有关联，要么关联较弱。这些结果描述了在一个大样本中根据水果和蔬菜摄入量得出的抗氧化剂血清浓度，并支持了先前涉及受试者数量较少的研究结果。
