Past 50 years, present, and future of the Korean Nutrition Society.

Created in 1967, the Korean Nutrition Society (KNS) has been a vital contributor to the development of the health and nutrition of South Korea. With members from many different fields focusing on nutrition and health sciences, the impact of the KNS has not only been felt in South Korea, but also worldwide. The KNS has helped to establish and maintain dietary recommendations in addition to providing ways to make nutrition information readily available to members, as well as the public. The KNS has also established professional journals to advance scientific discoveries in nutrition and health. With 50 years of progress from the KNS, their contributions to nutrition and health will continue to have an impact throughout the world. To celebrate the 50th anniversary and growth of the KNS, an International Conference entitled "Integrative Nutrition for an Active Life" was held by the KNS in November 2017. The articles in this special issue of Nutrition Research are to commemorate the KNS efforts.
