Evidence about the impact of vegetable and fruit diversity consumption on the autonomic nervous system (ANS) functioning is scarce. In this cross-sectional study (513 participants, 49.9% girls aged 7 to 12 years), we evaluated the association between vegetable and fruit diversity consumption and the ANS in school-aged children. Dietary intake was collected using a single 24-h recall questionnaire. Fruit and vegetable diversity consumption was estimated by summing up all the different individual vegetables and fruits consumed in one day. Pupillometry was used to assess pupillary light response, which evaluated the ANS activity. Adjusted linear regressions estimated the association between vegetable and fruit diversity consumption with pupillary light response measures. There was a positive and significant association between vegetable diversity consumption and the average dilation velocity, a measure related to the sympathetic nervous system activity (β-coefficient = 0.03, 95%CI: 0.002; 0.07). Our findings show that vegetable diversity consumption is associated with the ANS response, a possible early link between diet and health in school-aged children.
关于蔬菜和水果多样性消费对自主神经系统 (ANS) 功能影响的证据很少。在这项横断面研究中（513 名参与者，49.9%为 7 至 12 岁女孩），我们评估了在校儿童蔬菜和水果多样性消费与 ANS 之间的关系。膳食摄入量通过单次 24 小时回忆问卷收集。通过将一天中食用的所有不同的单个蔬菜和水果相加来估计水果和蔬菜多样性的消费。瞳孔测量法用于评估瞳孔光反应，这反映了 ANS 的活动。调整后的线性回归估计了蔬菜和水果多样性消费与瞳孔光反应测量值之间的关联。蔬菜多样性消费与平均扩张速度呈正相关，这一速度与交感神经系统活动有关（β 系数=0.03，95%CI：0.002；0.07）。我们的研究结果表明，蔬菜多样性消费与 ANS 反应有关，这可能是儿童时期饮食与健康之间的早期联系。
