Abstract


Kochujang, a Korean fermented soybean-based red pepper paste, has been reported to have beneficial health effects. The aim of this study was to examine the antiobesity effects of Kochujang as a supplement in overweight/obese subjects according polymorphisms in the obesity-linked gene, peroxisome proliferator activator receptor γ (PPARγ2). Sixty overweight/obese subjects, who had body mass indexes (BMI, kg/m2) ≥23 or waist/hip ratios (WHR) ≥0.90 for males or ≥0.85 for females, were randomly assigned to either taking 32?g/day of placebo or Kochujang for 12 weeks. Before and after the intervention, anthropometric and metabolic parameters and body fat distribution (by computed tomography) were measured. After PPARγ2 C1431T polymorphism was analyzed by PCR-restriction fragment length polymorphism, the differences among the four groups (wild and mutant alleles in Kochujang and placebo groups) were determined. Between the Kochujang (n?=?26) and placebo (n?=?27) groups, there were no differences in body composition, insulin resistance, or antioxidant biomarkers before and after intervention. Compared to placebo, Kochujang significantly decreased plasma triglyceride (TG), TG/high-density lipoprotein (HDL), and dietary intakes of protein, sodium, and potassium after age, sex, and BMI were adjusted. The beneficial effects of Kochujang on lowering of TG and TG/HDL were weakened in subjects with the PPARγ2 mutant T allele with increasing subcutaneous fat area. However, the interaction between Kochujang and the PPARγ2 T allele improved insulin sensitivity. The obesogenic variables affected by the T mutant allele of PPARγ2 C1431T SNP were different in overweight/obese subjects in response to Kochujang.
