Trend of Legume Intake in Korea: Data from Korea National Health and Nutrition Examination Survey 1998∼2018

Abstract

Abstract Objectives The purpose of this study was to investigate the legume intake of Korean adults. Methods To conduct this study, the subjects(total 86,222) who participated in the dietary intake survey (24 h recall method) were analyzed from the data of the 1998∼2018 Korea National Health and Nutrition Examination Survey (KNHANES). 24-hour dietary recall data from the Korean National Health and Nutrition Examination Survey were used to assess legume intake for different daily meal/cooking locations. Results In the last 20 years, legume intake of Korean adults has increased by 2.3 g from 33.8 g in 1998 to 36.1 g in 2018. However, the ratio of legume intake from total food intake decreased by 0.3% from 2.7% in 1998 to 2.4% in 2018. This can be seen as a decrease in legume intake as a whole food variety. In particular, male decreased 0.4% from 2.8% in 1998 to 2.4% in 2018, while female in the same period decreased 0.1% from 2.5% in 1998 to 2.4% in 2018. Conclusions Legume, as a whole, contain many healthy ingredients, such as isoflavones and genistein, and are rich in vegetable proteins. Increasing consumption of these legumes requires dietary education and recipe development.
