Therapeutic Intervention of Eriocitrin in the Reduction of Hyperglycemia in Pre-diabetic Individuals

Individuals aged 35-60 years and who present at least one of the following criteria: (1) increased fasting blood glucose from 6.1 to 7.0 mmol / L, (2) decreased glucose tolerance of 7 , 8 to 11.1 mmol / L, and (3) glycated hemoglobin with values between 5.7 and 6.4% 10 will be eligible to participate in this study. The exclusion criteria will be to use hypoglycemic, hypolipidemic drugs, dietary supplements (vitamins, minerals, bioflavonoids, prebiotics, probiotics or other bioactive compounds), exercise intensely (more than 10 hours per week), history of cardiovascular diseases , diabetes mellitus, liver and kidney disease. The selected individuals will be distributed randomly in 2 groups through random number generator program. Group A (n = 20) will receive 200 mg / d of eriocitrin for 12 weeks, with washout for 2 weeks and then receive 200 mg / d of placebo for 12 weeks; group B (n = 20) will receive 200 mg / d placebo for 12 weeks with washout for 2 weeks and then receive 200 mg / d placebo for 12 weeks. The primary endpoint will be fasting blood glucose, blood glucose 2 hours after oral glucose tolerance test (GTTO), and HbA1c. The secondary endpoint will be insulin, HOMA-IR, total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, ALP, yGT, AST, ALT, TNF-α, IL-6, CRP, body weight, body mass index BMI), muscle mass, fat mass, body fat and waist-hip ratio, and macronutrient intake.
