Abstract
The purpose of this study was to analyze the research trends on picky eating from 1999 to 2019 in Korea and to suggest directions for relevant future research. A total of 69 research articles were selected and analyzed according to the following criteria: Research methods (research designs; research subjects; and research tools), and research topics (current status of picky eating; effectiveness of intervention programs; and development of intervention programs). The results showed that research on picky eating has increased quantitatively since the 2010s, mostly identified using an experiment or a survey. In addition, intervention programs used for the research of this issue have gradually diversified beyond simple nutrition educations, incorporating cooking, garden-based, and sensory educations, etc. However, research tools with reliability and validity were scarce, and the research subjects in this literature review were limited mainly to infants and elementary school students. Overall, considering the critical impacts of picky eating on an unbalanced diet, more sophisticated research on picky eating will need to be actively conducted in the future.
