Biochemical evaluation
TG, high-density lipoprotein (HDL)-cholesterol
Venous blood samples were collected after 8-hour fasting before any intervention. Serum glucose, total cholesterol, high-density lipoprotein (HDL)-cholesterol and triglycerides (TG) were measured using an AutoAnalyzer technique (Technicon DAX96, Miles Inc). Low-density lipoprotein (LDL)-cholesterol concentrations were calculated using Friedewald’s equation when TG concentrations <400 mg/dl.
