Exploratory study on effect of eco-friendly program in high school foodservice on adolescents' dietary behavior and satisfaction with foodservice / 한국영양학회지

PURPOSE: The purpose of this study was to evaluate the effects of an eco-friendly foodservice program at a high school on dietary behaviors of students, awareness of importance of eco-friendly activities, and foodservice satisfaction. METHODS: The survey was conducted with students at two schools in Gyeonggi, Korea. A total of 576 of 650 students were used for this study. Data were analyzed using Chi-square test, independent t-test, and factor analysis to test the two group's differences. RESULTS: The practices of ‘eat balanced meals’ or ‘finish all food on the plate’ scored high (p < 0.001) in students that participated in the eco-friendly foodservice program than those who did not. Regarding awareness of the importance of eco-friendly activities, all attributes scored higher in students that participated in the eco-friendly foodservice program. All attributes for satisfaction except two scored higher (p < 0.05) in students that participated in the eco-friendly foodservice program. Principal Components Analysis (PCA) of the correlation showed that high subjective income status was positively associated with foodservice satisfaction. CONCLUSION: Students that participated in the eco-friendly foodservice program are highly aware of the importance of eco-friendly activities. They demonstrate more positive dietary behaviors and higher awareness of the importance of eco-friendly programs with greater foodservice satisfaction.

Dietary assessment according to frequency of food consumed away from home among children and adolescents: Based on the 2010~2012 Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: The aim of this study was to investigate the dietary quality of food consumed away from home among Korean children and adolescents. METHODS: Data were obtained from the 2010~2012 KNHANES (Korea National Health and Nutrition Examination Survey) and included 3,583 subjects aged 7 to 18 years old. The frequency of food consumed away from home was dichotomized into more than once or less than once per day. RESULTS: Thirty percent of subjects were shown to consume food away from home more than once per day, and older children from higher income households showed a higher frequency of food consumed away from home compared to other children. The percentage of children and adolescents cited as regularly skipping breakfast was 19%. Individuals who ate out more than once per day showed higher consumption of energy and sodium than those who ate out less than once per day. CONCLUSION: Excessive intakes of energy and sodium are associated with obesity, high blood pressure, diabetes, and obesity-related diseases. Thus, there is a need for nutritional intervention and educational efforts to improve child nutrition and prevent obesity.

Consumer perceptions on sustainable practices implemented in foodservice organizations in Korea

BACKGROUND/OBJECTIVES: Sustainable practices in foodservice organizations including commercial and noncommercial ones are critical to ensure the protection of the environment for the future. With the rapid growth of the foodservice industry, wiser usage of input sources such as food, utilities, and single use packaging should be reconsidered for future generations. Therefore, this study aims to investigate the customer's perceptions on sustainable practices and to identify the relationship among sustainable practices, social contribution and purchase intention. SUBJECTS/METHODS: The study was conducted using content analyses by reviewing articles on sustainable food service practices published domestically and abroad. Thereafter, data were collected with a face-to-face survey using a questionnaire and analyzed with factor analyses and multiple regressions. RESULTS: Sustainable practices classified with factor analysis consisted of 6 dimensions of green food material procurement, sustainable food preparation, green packaging, preservation of energy, waste management, and public relations on green activity, with a total of 25 green activities in foodservice operations. Consumers were not very familiar with the green activities implemented in the foodservice unit, with the lowest awareness of "green food material procurement (2.46 out of 5 points)", and the highest awareness of "green packaging (3.74)" and "waste management (3.28). The factors influencing the perception of social contribution by foodservice organizations among 6 sustainable practice dimensions were found to be public relations on green activity (beta = 0.154), waste management (beta = 0.204) and sustainable food preparation (beta = 0.183). Green packaging (beta = 0.107) and the social contribution of the foodservice organization (beta = 0.761) had strong relationships with the image of the organization. The purchase intentions of customers was affected only by the foodservice image (beta = 0.775). CONCLUSIONS: The results of this study suggest that sustainable practices by foodservice organization present a good image to customers and increase the awareness of valuable contributions that benefit the customer as well as the community.

However, a feasibility study should be conducted to test whether they are applicable to the field of restaurant operation.

Food allergy knowledge, perception of food allergy labeling, and level of dietary practice: A comparison between children with and without food allergy experience

BACKGROUND/OBJECTIVES: The prevalence of food allergies in Korean children aged 6 to 12 years increased from 10.9% in 1995 to 12.6% in 2012 according to nationwide population studies. Treatment for food allergies is avoidance of allergenic-related foods and epinephrine auto-injector (EPI) for accidental allergic reactions. This study compared knowledge and perception of food allergy labeling and dietary practices of students. SUBJECTS/METHODS: The study was conducted with the fourth to sixth grade students from an elementary school in Yongin. A total of 437 response rate (95%) questionnaires were collected and statistically analyzed. RESULTS: The prevalence of food allergy among respondents was 19.7%, and the most common food allergy-related symptoms were urticaria, followed by itching, vomiting and nausea. Food allergens, other than 12 statutory food allergens, included cheese, cucumber, kiwi, melon, clam, green tea, walnut, grape, apricot and pineapple. Children with and without food allergy experience had a similar level of knowledge on food allergies. Children with food allergy experience thought that food allergy-related labeling on school menus was not clear or informative. CONCLUSION: To understand food allergies and prevent allergic reactions to school foodservice among children, schools must provide more concrete and customized food allergy education.
