Effects of ginger supplementation on anthropometric, glycemic and metabolic parameters in subjects with metabolic syndrome: A randomized, double-blind, placebo-controlled study
Metabolic syndrome (MetS) is one of the worldwide most chronic endocrine disorders. The disease can also lead to several other chronic disorders such as type 2 diabetes mellitus, cardiovascular diseases, renal diseases and cancers. This study aimed to evaluate the safety and efficacy of ginger powder on biochemical and anthropometric parameters in patients with MetS.
This randomized controlled clinical trial was conducted on 37 patients with MetS. We supplemented the individuals with MetS with either 2 g per day ginger powder or placebo for 12 weeks. Biochemical and anthropometric parameters before and after the intervention were compared between the two groups.
After 12 weeks of treatment, the levels of triglyceride (TG), FBS, and insulin resistance were significantly improved in the patients receiving ginger in compare to the placebo group (P < 0·05). Moreover, significant changes were observed in terms of weight, waist circumference, LDL, HDL, total cholesterol, systolic and diastolic blood pressure and energy intake between the groups.
In general, our findings demonstrated that the ginger supplementation offers beneficial effects on patients with MetS, at least, in part due to the modulatory effects on TG, FBS, and insulin resistance.
