Preferences, Frequency and Consumption of Vegetables, Fruits & Milk, and Practices of Dietary Guidelines among Middle School Students in Chungbuk Area

The purpose of the study was to examine practice of dietary guideline for adolescents by investigating preferences, frequency and consumption of vegetables, fruits and milk. Survey for a self-administered questionnaire and 24-hr recall was conducted to 192 middle school students in the 2nd grade at Jeungpyeong District, Chungbuk in July, 2009. Approximately 55% of the students answered that they are picky about some kind of foods, 68% of which were vegetables. Preference scores of tomato, strawberry, ice cream were the highest, and pepper, persimmon, white milk were the lowest among vegetables, fruits, and milk & milk products, respectively. The results of food frequency questionnaire showed that chinese cabbage, watermelon, white milk & ice cream were the most frequently consumed, and spinach & zucchini, persimmon, and flavored milk were the least consumed among vegetables, fruits, and milk& milk products. When nutrient intakes from vegetables alone were estimated, boys consumed significantly higher calcium, phosphorus, iron, vitamin A, and folate from vegetables than girls. However, there were no significant differences in nutrient intakes from fruits or milk & milk products between boys and girls. As for the practice of dietary guidelines, 27.1% of the students consumed vegetables 3 times or more a day, 43.7% of the students consumed fruits once or more a day, and 42.2% consumed 2 glasses of milk or more a day as recommended by dietary guidelines. Our results showed that many adolescents do not like vegetables and do not eat frequently enough vegetables, fruits and milk as recommended by dietary guidelines. Efforts to increase consumption of vegetables, fruits, and milk such as developing new recipes and incorporating nutrition education class in school curriculum are needed with the support of family and school together.
