title: Effects of probiotic yogurt consumption on lipid profile in type 2 diabetic patients: A randomized controlled clinical trial.
abstract: BACKGROUND
  Alteration in plasma lipid and lipoprotein profile has been documented in diabetic patients. The purpose of this study was to compare the effect of probiotic and conventional yogurt on lipid profile in type 2 diabetes mellitus patients.
  
  
  METHODS
  A total of 44 patients with type 2 diabetes aged 30-60 years old who had low density lipoprotein cholesterol (LDL-c) ≥100 mg/dl enrolled in this randomized, double - blind controlled trial and were assigned to two intervention and control groups. The subjects in the intervention group consumed 300 g/d probiotic yogurt containing Lactobacillus acidophilus La-5 and Bifidobacterium lactis Bb-12 and subjects in the control group consumed 300 g/d conventional yogurt for 8 weeks. Anthropometric indices, dietary intake, and serum lipid profile were evaluated at the beginning and end of the intervention. Independent-sample t-test, paired sample t-test, ANCOVA, and repeated measures were used for statistical analysis.
  
  
  RESULTS
  The consumption of probiotic yogurt caused significant decrease in LDL-c/high density lipoprotein cholesterol (HDL-c) ratio (3.13 ± 1.00-2.07 ± 0.71, P = 0.016). The levels of HDL-c were increased significantly (43.66 ± 6.80-50.42 ± 6.64, P = 0.023) in the intervention group postintervention. However, there were no significant differences in triglyceride and total cholesterol levels between two groups postintervention (P < 0.05).
  
  
  CONCLUSIONS
  It is suggested that probiotic yogurt consumption may be used as an alternative prevention approach and treatment method to improve dyslipidemia in patients with type 2 diabetes.
