Abstract

Introduction

The aim of this cross-sectional study was to investigate the association between a healthier diet, perceived immune fitness, and biomarkers of the immune system.

Methods

N = 108 participants (31 men and 77 women), 18–30 years old, completed a questionnaire, comprising the Healthy Diet Scale (HDS) and a 1-item scale assessing perceived immune fitness. In addition, saliva samples were collected and C-reactive protein (CRP) and cytokine concentrations of interleukin (IL)− 1β and IL-8 were determined.

Results

Overall, a significant correlation was found between the HDS score and perceived immune fitness (r = 0.221, p = 0.021), suggesting that a healthier diet was associated with a better immune fitness. The HSD score correlated significantly and negatively with saliva CRP concentrations (r = −0.240, p = 0.013). No significant correlations were found with other biomarkers. In women, the HDS correlated significantly with perceived immune fitness (r = 0.247, p = 0.030) and CRP levels ( r = −0.281, p = 0.014). In men, correlations with perceived immune fitness ( r = −0.219, p = 0.237) and the biomarkers were not significant.

Discussion

Significant associations between attaining a healthy diet, perceived immune fitness and CRP were found. More research is needed to investigate the observed sex differences and underlying mechanisms.

更健康的日常饮食与更强的免疫适应性有关
本横断面研究的目的是调查健康饮食、感知免疫适应性和免疫系统生物标志物之间的关系。方法108名男性31名,女性77名,年龄18-30岁,填写健康饮食量表(HDS)和感知免疫适应性1项量表。此外,收集唾液样本,检测c反应蛋白(CRP)和白细胞介素(IL) - 1β和IL-8的细胞因子浓度。结果总体而言,HDS评分与感知免疫适应性之间存在显著相关(r = 0.221, p = 0.021),表明更健康的饮食与更好的免疫适应性相关。HSD评分与唾液CRP浓度呈显著负相关(r = - 0.240, p = 0.013)。与其他生物标志物无显著相关性。在女性中,HDS与感知免疫适应性(r = 0.247, p = 0.030)和CRP水平(r = - 0.281, p = 0.014)显著相关。在男性中,感知免疫适应度(r = - 0.219, p = 0.237)和生物标志物之间的相关性不显著。发现健康饮食、感知免疫适应性和CRP之间存在显著关联。需要更多的研究来调查观察到的性别差异和潜在的机制。
