Allergic Rhinitis (AR) is one of the most common immune-related diseases that affects the quality of life among patients. This study aims to investigate the effect of adequate Se intake on the severity of symptoms and quality of life among participants with AR<b>. </b></span></span><b><span lang="FR" style="font-size:10.0pt"><span new="" roman="" style="font-family:" times="">Methods: </span></span></b><span lang="FR" style="font-size:10.0pt"><span new="" roman="" style="font-family:" times="">A total of 60 participants were recruited for the study and were divided into 2 groups; adequate Se intake (adSe) group and inadequate Se intake (InadSe) group </span></span><span style="font-size:10.0pt"><span new="" roman="" style="font-family:" times="">based on nutritional suggestion calculated using a nutritional software package</span></span><span lang="FR" style="font-size:10.0pt"><span new="" roman="" style="font-family:" times="">.
