소변은 쉽게 채취할 수 있으며 체내의 상태를 파악하기에 좋은 시료라고 할 수 있다. 본 연구에서는 2주간의 한식 섭취 후 변화된 소변 유기산 지표를 찾을 수 있었다. 그 결과 에너지 대사와 관련 있는 대사산물인 succinate, hydroxymethylglutarates 뿐만 아니라 tryptophan 대사물로써 신경전달 물질대사 지표인 5-hydroxyindoleacetate, 비타민 B6, 염증, 면역과도 관련이 있는 kynurenate, 장내세균과 관련 있는 indican이 한식의 섭취를 통해 유의한 차이로 변화하는 것을 확인하여 한식의 효능이 어떤 대사를 통하여 이루어 지는지의 방향 제시를 하였다. 또한 소변 유기산이 한식의 대사에 미치는 영향을 측정하는 생체지표로서의 활용 가능성도 보여주었다. 객관적인 지표로서 확증하기 위해 더욱 큰 표본에서의 연구, 성별, 질병별 다양화한 연구를 통해 관찰된 지표들의 재현성을 확인하여 생체 지표로서의 유효성 검증이 필요하겠다.

Purpose: To determine the metabolic influence of the traditional Korean diet (K-diet), which has been regarded as a healthy diet, we investigated the profile of urine organic acids that are intermediates of various types of metabolism including energy metabolism.
Methods: Ten women aged 50–60 years were recruited and randomly divided into 2 diet groups, K-diet and control diet, the latter of which is a Westernized Korean diet that is commonly consumed by Koreans nowadays. Before and after the 2-week intervention, 46 urine organic acids were determined using LC/MS/MS, along with clinical parameters.
Results: The average concentrations of succinate (4.14 ± 0.84 μg/mg creatinine vs. 1.49 ± 0.11, p = 0.0346) and hydroxymethylglutarate (3.67 ± 0.36 μg/mg creatinine vs. 2.97 ± 0.29, p = 0.0466), both of which are intermediates of energy metabolism, decreased in the K-diet group after the 2-week intervention, but these were not observed in the control diet group. In particular, the average concentration of succinate in the K-diet group was lower than that in the control group (3.33 ± 0.56 μg/mg creatinine vs. 1.49 ± 0.11, p = 0.0284) after 2 weeks. The concentrations of two tryptophan metabolites, 5-hydroxyindolacetate (3.72 ± 0.22 μg/mg creatinine vs. 3.14 ± 0.21, p = 0.0183) and indican (76.99 ± 8.35 μg/mg creatinine vs. 37.89 ± 10.06, p = 0.0205) also decreased only in the K-diet group. After the 2-week intervention, the concentration of kynurenate, another tryptophan metabolite, was lower in the K-diet group than that in the control diet group (3.96 ± 0.51 μg/mg creatinine vs. 2.90 ± 0.22, p = 0.0356). Interestingly, the urine level of kynurenate was positively correlated with BMI (r = 0.61424, p = 0.0003) and total cholesterol (r = 0.46979, p = 0.0088), which decreased only in the K-diet group (239.40 ± 15.14 mg/dL vs. 198.20 ± 13.25, p = 0.0163).
Conclusion: The K-diet alters the urinary excretion of organic acids involved in energy metabolism and tryptophan metabolism, suggesting the influence of the K-diet on these types of metabolism. Urine organic acids changed by the K-diet may serve as biomarkers in future studies.
