The aim of the present study was the association between the relationship between Dietary Quality Index-International (DQI-I) and Healthy Eating Index (HEI) and the urinary levels of F-isoprostane (F-IP) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) was investigated as indicators of oxidative stress.
Based on HEI (low, moderate, and good), the diet quality of both groups was classified as moderate. In all participants, HEI (β=-0.29; P = 0.04) and DQI-I (β=-0.46; P = 0.005) were inversely associated with 8-OHdG. Furthermore, a negative correlation was found between HEI (mean β=-3.53; P = 0.04) and DQI-I (mean β=-5.53; P = 0.004) with F-IP. The quality of the footballers' diet was higher than that of the control group. Following a high-quality diet, which is rich in antioxidants, is likely to effectively reduce oxidative stress.
本研究旨在探讨膳食质量指数-国际（DQI-I）与健康饮食指数（HEI）与尿液中 F-异前列烷（F-IP）和 8-羟基-2'-脱氧鸟苷（8-OHdG）水平之间的关系，作为氧化应激的指标。
根据 HEI（低、中、高），两组的饮食质量均被归类为中等。在所有参与者中，HEI（β=-0.29；P=0.04）和 DQI-I（β=-0.46；P=0.005）与 8-OHdG 呈负相关。此外，还发现 HEI（平均β=-3.53；P=0.04）和 DQI-I（平均β=-5.53；P=0.004）与 F-IP 呈负相关。足球运动员的饮食质量高于对照组。食用富含抗氧化剂的高质量饮食可能会有效降低氧化应激。
