In 1968, Dudrick et al. [1] pioneered the concept of “total parenteral nutrition” by successfully providing nutrition through intravenous injection alone to a fasting beagle puppy. This paved the way for the development of high-concentration intravenous nutrition therapy through central veins, overcoming the limitations of peripheral venous nutrition. In recent years, advancements in nutrition therapy have expanded treatment options in various directions including to omega-3, glutamine, micronutrients, and multivitamins. Additionally, the active involvement of a Nutrition Support Team in Korean hospitals has established a solid foundation for inpatient nutrition therapy through a multidisciplinary approach. This allows for more personalized and preventive nutrition therapy in patient care. Despite these developments, there is still insufficient evidence for the effectiveness of current nutrition care, and most is based on the results of foreign clinical studies.

Consequently, it is necessary to establish goals for obtaining practical evidence on Korean nutrition care based on domestic clinical data. The Annals of Clinical Nutrition and Metabolism hopes to provide a new opportunity for the establishment and sharing of evidence-based practices in Korea and looks forward to more active presentation of research outcomes from collaborative, multidisciplinary teams.
