Effects of High Performance Inulin Supplementation on Glycemic Status and Lipid Profile in Women with Type 2 Diabetes: A Randomized, Placebo-Controlled Clinical Trial
Abstract
Background: Type 2 diabetes mellitus, as a noncommunicable disease, is the main public health challenge in the 21st century. The prevalence of di¬abetes mellitus adjusted for the world population in Iran was 8% until the year 2010. Lipid levels are considered as important parameters to be eva¬luated, as high serum lipid levels are often reported as a complication in patients with diabetes mellitus. It is claimed that functional foods may im¬prove complications of diabetes mellitus, so this study was designed to evaluate the effects of high performance inulin on glycemic status and lipid profile of women with type 2 diabetes.Methods: The study was a randomized controlled clinical trial. Forty-nine type 2 diabetic females (fiber intake <30g/d, 25<BMI<35 kg/m2) were divided into two groups. Patients in the intervention group (n=24) re¬ceived 10g/d inulin and patients in the control group (n=25) received 10g/d maltodextrin for 8 weeks. Glycemic status and lipid profile indices were measured pre and post intervention. Data were analyzed using SPSS software (verision11.5). Paired, unpaired t-test and ANCOVA were used to compare quantitative variables.Results: Supplementation with inulin caused a significant reduction in FBS (8.50%), HbA1c (10.40%), total cholesterol (12.90%), triglyceride (23.60 %), LDL-c (35.30 %), LDL-c/HDL-c ratio (16.25%) and TC/HDL-c ratio (25.20%) and increased HDL-c (19.90%). The changes for the control group parameters were not significant at the end of study. Conclusion: Inulin may help to control diabetes and its complications via improving glycemic and lipid parameters.
