Effect of Ellagic Acid Administration on the Components of Metabolic Syndrome, Insulin Sensitivity and Insulin Secretion

INTRODUCTION: Ellagic acid (EA) is a polyphenol that has shown health benefits in multiple experimental studies; mainly as an antioxidant, but also in hepatic steatosis, endothelial damage, hypertension, diabetes mellitus, visceral fat accumulation, dyslipidemia, insulin resistance, atherosclerosis, etc. There aren't studies that demonstrate the effectiveness of EA on MetS; since patients consume it without any prescription, it is important to evaluate the effect of the administration of EA on the components of metabolic syndrome, insulin sensitivity, and insulin secretion. The current design is a randomized double-blind, placebo-controlled, clinical trial. METHODS: Male and female volunteers between 30 to 59 years of age, with a diagnosis of MetS according to the International Diabetes Federation criteria will be included, whether they accept participating and signing the informed consent. Patients with one or more of the following criteria will be excluded: History of liver, kidney, heart, or thyroid disease; diabetes mellitus or arterial hypertension, alcohol, drug abuse or tobacco use, systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, fasting blood glucose ≥126 mg / dL, triglycerides ≥500 mg/dL, LDL cholesterol >190 mg/dL; suspected or confirmed pregnancy, lactation, menopausal period <1 year, hormonal contraceptive or replacement therapy, pharmacological, dietary or herbal therapy in the last 3 months before trial, allergy to any of the interventions. Patients included, may be withdrawn from the study if they meet any of the following conditions: Withdrawal of the informed consent, severe adverse reaction, loss of follow-up, treatment adherence <80%; intolerance to EA or placebo. OBJECTIVES: The main objective is to evaluate the effect of EA or placebo on metabolic syndrome components, insulin sensitivity, and insulin secretion. HEADQUARTERS: The study will be carried out in the facilities of the Institute of Experimental and Clinical Therapeutics (INTEC), of the University Center of Health Sciences, at the University of Guadalajara.
