摘要: BACKGROUND/OBJECTIVE: This study aims to measure the in vitro antioxidant capacity of Korean diet (KD) with American (AD) as a control group and examine ex vivo DNA damage reduction effect on human lymphocytes. MATERIALS/METHODS: The KD applied this is standard one-week meals for Koreans (2,000 kcal/day) suggested by 2010 Dietary Reference Intakes Koreans. AD, which group, menu that consists foods Americans would commonly take according National Health Nutrition Examination Survey. each was measured means total phenolic assay 3 activity assays (2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, trolox equivalent (TEAC), Oxygen absorbance (ORACROOㆍ)), while extent lymphocyte comet assay. RESULTS: When TEAC assay, day higher than AD (P CONCLUSION: demonstrates high protective KD, generally various plant foods, are those typical AD.
