Effect of Ziziphus jujube Fruit Infusion on Lipid Profiles, Glycaemic Index and Antioxidant Status in Type 2 Diabetic Patients: A Randomized Controlled Clinical Trial.

Abstract

This study was designed to assess the effects of Ziziphus jujube fruit (ZJF) infusion on lipid profiles, glycaemic control and antioxidant status in patients with type 2 diabetes mellitus (T2DM). In this randomized controlled clinical trial, 116 participants with T2DM (older than 30years) were assigned to consume a balanced diet or diet plus ZJF infusion (10g/100mL boiling water) three times/day before main meals for 12weeks. Diet was designed to be energy restricted (500kcal/day deficit from estimated energy requirements), and macronutrient content was similar in both groups (55% carbohydrate, 15% protein and 30% fat). The consumption of ZJF infusion compared with the control group was associated with significant improvement in glycosylated haemoglobin (-0.68±0.65 vs. -0.44±0.55%; p=0.03), total cholesterol (-24.29±28.89 vs. -11.21±29.98mg/dL; p=0.02), triglycerides (-43.3±39.26 vs. -27.16±46.84mg/dL; p=0.05), low-density lipoprotein cholesterol (-19.85±27.62 vs. -6.55±27.82mg/dL; p=0.01), low-density lipoprotein cholesterol/high-density lipoprotein cholesterol (-0.56±0.80 vs. -0.2±0.72; p=0.01) and total cholesterol to high-density lipoprotein cholesterol ratios (-0.73±0.94 vs. -0.35±0.77; p=0.02). ZJF had beneficial effects on glycosylated haemoglobin and lipid profile in T2DM patients. Further research is needed to identify the mechanism of ZJF action on glucose and lipid metabolism.
