A rapid increase in urbanization and industrialization brings about a change in economic status which results in considerable changes in lifestyle including food habits and disease and mortality patterns. The purpose of the present study was to investigate recent food habit changes if any, reasons for food habit change, current food consumption patterns, and breakfast practices among urban adults with middle and upper income levels. Three hundred men and women, aged 20-60 years, were randomly selected and interviewed individually by trained interviewers. Among the twenty food groups studied, subjects reported that, compared to two years ago, they are now eating more fast foods, meats, fish, vegetables and fruits, and less rice, noodles, pastries, and salt. The changes in fast foods, fruits, and rice consumption patterns varied significantly between age, sex, income level, and BMI groups. The two most primary reasons for food habit changes were 'for my own health' and 'for my family's health', which shows that health seems to be the major concern in changing food habits. Among meals, the breakfast meal was rated as the most important one, and was not affected by the sociodemographic variables. However, the average rate of skipping breakfast was found to be as high as 33% with a greater rate in younger age groups. The rats of breakfast skipping was found to vary between different income, education, and BMI groups. Among the subjects who eat breakfast meals daily, a traditional Korean breakfast of rice and soup was found to be still a predominant choice, although younger age groups, upper income groups, and people with more education choice, although younger age groups, upper income groups, and people with more education tended to eat a western-style breakfast more frequently. These findings are applicable at the planning and implementation stages of various nutritional improvement projects as a part of the National health Promotion Law.
