Effects of Propolis Supplementation on Metabolic Syndrome Indices, Isfahan, Iran, 2023: A Randomized Controlled Clinical Trial

Abstract

Background and Aim Propolis is a resinous substance collected from plant buds and secretions by bees, possesses numerous medicinal and biological properties, including immune modulation, anticancer effects, antimicrobial activity, anti-inflammatory properties, and antioxidant properties. This study aims to examine the effect of the propolis on metabolic syndrome (MetS) indices among patients with MetS.Methods This study as a randomized controlled clinical trial (RCT), was conducted on patients with MetS who were referred to the Hazrat Ali Health Center in Isfahan. Fifty six eligible patients were classified into two groups. including MIND (The Mediterranean-DASH Intervention for Neurodegenerative Delay) diet + placebo and MIND diet + propolis. We evaluated the MetS indices (Fasting Blood Sugar (FBS), waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C)). We used the Shapiro-Wilk test to determine if the distribution of quantitative variables was normal. Quantitative variables were presented as either the mean with standard deviation (SD).Results MIND + propolis group compared to MIND group showed nonsignificant decrease about body mass index (BMI) after adjusting variables 0.9 times (10), 0.8 times (20), respectively, and also showed nonsignificant decrease about TG by 0.9 times (10), and also nonsignificant increase about WC and mean arterial pressure (MAP = SBP + 2DBP/3) by 1.03 times (3%) and 1.3 times (30%), respectively, and HDL-C significant increased by 12.8 times.Conclusion MIND + propolis group compared to MIND group showed significant increase HDL-C. therefore; propolis increase significantly HDL-C.
