Plain language summary
Metabolic syndrome is a cluster of conditions related to cardiovascular disorders risk factors such as blood pressure, dyslipidaemia, hyperglycaemia, excess body fat around the waist and insulin resistance. The aim of this study was to assess the effects of a gluten-free diet on components of metabolic syndrome in patients diagnosed with metabolic syndrome. The study is a randomised control trial that recruited fifty subjects diagnosed with metabolic syndrome. Subjects were block randomised by gender into control and gluten-free diet groups. Results showed that a gluten-free diet induces significant reduction in waist circumference in comparison to control diet. Reduction in waist circumference without significant reduction in body weight may indicate preferential loss of abdominal fat. Furthermore, results indicate that a gluten-free diet improved glucose tolerance. Authors conclude that a gluten-free diet significantly improved some key features of metabolic syndrome including blood glucose and serum triglycerides.
Background: This study aimed to assess the effects of Gluten free diet (GFD) on components of metabolic syndrome (MES). Materials and Methods: In this randomized clinical trial, 50 subjects diagnosed with MES were randomly divided into two groups (n=25). The first group received a GFD and the second group continued their regular diet. Biochemical markers of MES and blood pressure were measured before and after 8-week intervention. Results: Forty five subjects completed the study. A post-hoc comparison of the groups showed no effects of the GFD and control diet on LDL cholesterol, total cholesterol, fasting insulin, HOMA-IR, systolic and diastolic blood pressure levels. The GFD reduced fasting blood glucose, waist circumference (WC) and serum triglyceride concentration significantly compared with the control diet (p<0.05). Conclusion: Short-term GFD reduced WC and improved glycemic control and Triglyceride level in subjects with the metabolic syndrome.
