title: Effect of functional yogurt NY-YP901 in improving the trait of metabolic syndrome.
abstract: OBJECTIVE
  This study was aimed to assess the beneficial effects on metabolic syndrome of functional yogurt NY-YP901 (Namyang Dairy Product Co. Ltd and Nutra R&BT Inc., Seoul, Korea) supplemented with mixture of Streptococcus thermophilus, Lactobacillus acidophilus, Bifidobacterium infantis and extra-ingredients containing Bifidobacterium breve (CBG-C2), Enterococcus faecalis FK-23, fibersol-2 and so on.
  
  
  METHODS
  This study was designed as an 8-week randomized, double-blind, placebo-controlled, parallel study. Treatment and control groups consumed a functional yogurt NY-YP901 (150 ml) and a placebo yogurt twice a day, respectively, for 8 weeks. Body weight and body mass index (BMI), blood pressure, lipid profiles, fasting glucose with HbA1C and waist circumference were measured before and after treatment. Inclusion criteria were healthy individuals between the ages 20-65 years old who submitted an informed consent.
  
  
  RESULTS
  During the period August 2009 to December 2009, 101 healthy participants (31 males and 70 females) finished the study. Treatment group were 53 individuals, and the control group were 48 individuals. In the treatment group consuming NY-YP901, statistically significant beneficial changes were observed in body weight (treatment group vs control group=-0.24±1.50 vs +0.64±1.39 kg, P<0.05), BMI (-0.10±0.58 vs +0.24±0.50 kg/m(2), P<0.05 ) and low-density lipoprotein (LDL)-cholesterol (-7.71±14.14 vs -0.43±15.32 mg/dl, P<0.05) after 8 weeks. The change in other parameters was not different between the treatment and the control groups.
  
  
  CONCLUSIONS
  The functional yogurt NY-YP901 reduced LDL-cholesterol, body weight and BMI in the subjects at a 300-ml consumption daily for 8 weeks. From these findings, regular intake of functional yogurt NY-YP901 may be consequently related to improve metabolic syndrome.
