ABSTRACT
BACKGROUND: Metabolic syndrome is a cluster of condition where one of its risk factor, elevated fasting blood glucose (FBG) is associated with the development of diabetes. Selenium, an essential trace mineral, is found to protect our body cells against oxidative stress which is observed with diabetes progression. Nevertheless, the association of dietary selenium intake and FBG had been inconclusive.
METHODOLOGY: In this cross-sectional study, we investigated the association of dietary selenium intake with FBG among 97 participants aged 20 to 55 years old in Klang Valley. Food frequency questionnaire (FFQ) was used to determine the dietary selenium intake of the study population. The FBG of the participants were measured via finger prick method by using One Touch Select Glucose Monitor after at least 8 hours of fasting.
RESULTS: The mean dietary selenium intake of the study population was 62.16 ± 32.93 mcg/day which is about 130% above the Recommended Nutrient Intake (RNI) for Malaysia 2017. The median FBG of the study population was 4.8(0.53) mmol/L. There was no significant association found between dietary selenium intake and FBG (r = 0.040, p = 0.696).
CONCLUSION: An increase in dietary selenium intake above the RNI for both male and female does not pose a great concern on the risk of diabetes development.
