2. Laboratory Blood sample will be drawn after 12 hours fast to measure triglycerides, total cholesterol and HDL-cholesterol, glycemia, serum creatinine, ultrasensitive reactive C protein (RCP), Alanine aminotransferase and HbA1c. Microalbuminuria also will be evaluated. Diabetic subjects will be identified by history of diabetes with dietetic treatment for diabetes or in use of hypoglycemic drugs. Subjects will be considered diabetic after 2 fasting glucose more than 125 mg/dl, according with National Diabetes Data Group. Serum cholesterol will be evaluated according Brazilian Guideline of Dyslipidemia. Low density lipoprotein cholesterol (LDLc) will be calculated by the Friedewald formula for triglycerides (TG) levels below 400 mg/dL ( LDLc = TC - HDLc - TG/5 (para TG < 400 mg/dL).
