Epidemiological studies have suggested an association between selenium (Se) and diabetes mellitus (DM). However, different studies have reported conflicting results. Therefore, we performed a comprehensive meta-analysis to clarify the impact of Se on DM.
We searched the PubMed database for studies on the association between Se and DM from inception to June 2018.
Twenty articles evaluating 47,930 participants were included in the analysis. The meta-analysis found that high levels of Se were significantly associated with the presence of DM (pooled odds ratios [ORs], 1.88; 95% confidence interval [CI], 1.44 to 2.45). However, significant heterogeneity was found (
This meta-analysis demonstrates that high levels of Se are associated with the presence of DM. Further prospective and randomized controlled trials are warranted to elucidate the link better.

The Association of Circulating Selenium Concentrations with Diabetes Mellitus
The purpose of this study was to evaluate the effects of high performance inulin supplementation on blood glycemic control and antioxidant status in women with type 2 diabetes.
In a randomized, triple-blind controlled trial, 49 females (fiber intake <30 g/day, 25<body mass index <35 kg/m2) with type 2 diabetes were recruited from the Iran Diabetes Society and from endocrinology and metabolism clinics associated with the Tabriz University of Medical Science. The participants were divided into one of two groups in which the participants either received 10 g/day of inulin (intervention,
At the end of the study period, there were significant decreases in fasting plasma glucose (8.47%), glycosylated hemoglobin (10.43%), and malondialdehyde (37.21%) levels and significant increases in total antioxidant capacity (18.82%) and superoxide dismutase activity (4.36%) in the inulin group when compared to the maltodextrin group (
Inulin supplementation may improve some glycemic and antioxidant indices and decrease malondialdehyde levels in women with type 2 diabetes. Further investigations are needed in order to confirm the positive effects that inulin may have on the glycemic and antioxidant indices of patients with type 2 diabetes.
