Association between dietary zinc intake and olfactory dysfunction: a study based on the NHANES database

ConclusionDaily dietary zinc intake within the range of 9.60 –17.45 mg has a protective effect against olfactory dysfunction. Intake outside this range increases the prevalence of olfactory dysfunction. The prevalence of olfactory dysfunction is significantly higher in individuals aged 60 and above compared to those under 60 years old. For individuals wit h a BMI of 25–30 kg/m2 and a BMI  ≥ 30 kg/m2, dietary zinc intake is negatively correlated with olfactory dysfunction. Therefore, it is recommended that these populations increase their dietary zinc intake to develop healthier lifestyles and maintain olfactory health.
