Vegetable intake in Korea: data from the Korean National Health and Nutrition Examination Survey 1998, 2001 and 2005.
The purpose of the present study was to analyse vegetable intake by the Korean population based on different meal formats. Twenty-four-hour dietary recall data from the Korean National Health and Nutrition Examination Survey were used to assess daily vegetable intake and consumption ratio of vegetables for different meal types/dining locations. Analysis was stratified by sex and age group. Daily vegetable intake increased from 293.5 g in 1998 to 305.7 g in 2001 and to 335.9 g in 2005. Findings were similar in men and women, as well as in each age group. Analyses for each meal type revealed that vegetable intake during breakfast did not substantially change, but vegetable intake increased during lunch and dinner. While vegetable consumption ratio during breakfast decreased, it increased during lunch and snack time. Men and women showed similar change in the analysis for meal types and dining locations. There were some differences between the age groups in daily vegetable intake depending on the meal type. Another notable observation was the increasing change of vegetable intake during lunch and during meals eaten at cafeterias and restaurants in all the age groups. Analysis of vegetable consumption ratio showed an increased consumption in cafeterias, restaurants, and other places and decreased vegetable intake at home for those aged 16-64 years with time. Since this change may be related to improvements in socioeconomic status, it will be necessary to further investigate difference in vegetable intake based on socioeconomic levels within the population.
