Abstract
This study presents the nutrition survey methods and the updated food composition database for the Korean Genome and Epidemiology Study (KoGES). The KoGES, which is the largest and longest cohort study in Korea, aims to identify genetic and environmental factors associated with chronic diseases. This study has collected dietary data using a validated semi-quantitative food frequency questionnaire and/or the 24-hour recall method. However, these dietary survey methods use different food composition databases, and their nutritional values are out of date. Therefore, it became necessary to update the food composition database by revising nutrient analysis values to reflect improvements in the performance of food ingredient analysis equipment, revising international values to analysis values of Korean agricultural products, adjusting nutrient units, and adding newly reported nutrients related to chronic diseases. For this purpose, we integrated the different food composition databases used in each nutrition survey, updated 23 nutrients, and expanded 48 new nutrients for 3,648 food items using the latest reliable food composition databases published by national and international institutions. This revised food composition database may help to clarify the relationship between various nutrients and chronic diseases. It could serve as a valuable resource for nutritional, epidemiological, and genomic research and provide a basis for determining public health policies.

Summary
Korean summary
한국인유전체역학조사사업은 우리나라에서 가장 크고 오래된 코호트로 만성질환과 영양과의 관련성을 밝히기 위하여 사용되고 있다. 이 논문에서는 영양조사에 대한 자세한 방법론과 현재 공개하고 있는 23개 영양소의 업데이트 및 48개 새로운 영양소의 확대에 대한 내용을 소개하였다. 이러한 개선을 통해 KoGES 영양 데이터의 활용도가 더욱 높아질 것으로 기대된다.
Key Message
The Korean Genome and Epidemiology Study (KoGES) is the largest and longest-running cohort study in South Korea aimed at identifying the relationship between chronic diseases and nutrient intake. This paper provides a detailed methods of the nutritional surveys and introduces updates to the existing 23 nutrients and the addition of 48 new nutrients. These enhancements are expected to significantly increase the utility of the KoGES nutritional data.
