BACKGROUND/OBJECTIVES: The purpose of this study is to identify how level of information affected intention, using the Theory of Planned Behavior. SUBJECTS/METHODS: The study was conducted survey in diverse community centers and shopping malls in Seoul, which yielded N = 209 datasets. To compare processed foods consumption behavior, we divided samples into two groups based on level of information about food additives (whether respondents felt that information on food additives was sufficient or not). We analyzed differences in attitudes toward food additives and toward purchasing processed foods, subjective norms, perceived behavioral control, and behavioral intentions to processed foods between sufficient information group and lack information group. RESULTS: The results confirmed that more than 78% of respondents thought information on food additives was insufficient. However, the group who felt information was sufficient had more positive attitudes about consuming processed foods and behavioral intentions than the group who thought information was inadequate. This study found people who consider that they have sufficient information on food additives tend to have more positive attitudes toward processed foods and intention to consume processed foods. CONCLUSIONS: This study suggests increasing needs for nutrition education on the appropriate use of processed foods. Designing useful nutrition education requires a good understanding of factors which influence on processed foods consumption.

This study was conducted to examine the consumption realities of processed food and the perception of food labeling with targets of university students attending schools in Daegu and Gyeongbuk areas. The reason for buying processed food was because it is easy to cook. As for the number of using processed food, it was answered that everyday dairy products, noodles, breads and snacks for 3~4 times a month, and meat processed foods, canned foods, sauces and frozen foods for 2~3 times a month. With regard to selecting processed products, both male and female students answered with taste and price first, barely considering the safety and nutritional elements. It turned out that they check the price, expiration date and country of origin in order upon buying processed foods. Most of them recognized food labeling, but answered that they checked it sometimes in order to check the 'expiration date' and the 'calories'. They were aware of the food nutritional contents indication. It was turned out that male students check it for nutrients and female students for weight control. The effect of the processed food indication was that it is easy to choose the necessary foods for health and as well as for comparing the food with other products. The satisfaction of the food labeling system was mediocre. The results indicated that the food indication system needs to be educated or promoted.

This study was carried out to strengthen productivity and employee management through the development of simple pre-processed foods based on Hansik (Korean foods) and to investigate the utilization of fresh vegetable menus, pretreatment, and cooking time in the preparation of vegetable side dishes. The reasons for not using pretreated foods were increased cost, required product size is not available, and not hygienic. The acceptable rate of increase in cost when purchasing simple pre-processed foods was under 10%. The expected developed products of simple pre-processed vegetable foods were balloon flower root salad, seasoned green vegetables, and sheredded white radish. The expected developed products of simple mixed vegetable pre-processed foods were deodeok+balloon flower root and white radish+pear. Based on these findings, to increase the utilization of simple preprocessed foods, development of various product sizes and sauces is needed, cost must be reduced, and hygiene improved.

While jujubes are mainly sold in dried forms as wholesome foods, sacrificial food and so on, processed foods from jujube are neither highly recognized nor in high demand. Hence, this study has proposed ways to enhance the demand for jujube processed foods and will help prepare the ground for efficient marketing strategies, based on the survey result on the pattern in which customers in Korea purchase jujube-processed foods. The conclusion for this study has been derived by researching the relevant literature and analyzing the relevant company data and customer survey results. The study implies the following points regarding enhancing the demand for jujube-processed foods. First, long-term solutions are necessary. These may include establishing a technological system that can produce various foods processed from jujubes, and improving the customer accessibility in accordance with the changes in the retail environment. To implement these solutions, it is necessary to familiarize the customers with jujube-processed foods by securing a good sales network and through active promotion and advertising. Second, systematic marketing strategies are needed, which may be applied in developing the products as well as distribution and promotion methods and prices that correspond with the changes in the customer environment and the different tastes for various age, gender and residential area groups.

Diet is closely related to an economic level, but few studies have reported on the relationship between the economic level and eating habits, especially in college students. Therefore, this study was conducted to clarify differences in eating habits with a focus on processed foods according to allowance level in college students. This study was a cross-sectional survey of 500 college students using a questionnaire. The questionnaire consisted of general characteristics, eating behaviors, purchase of processed foods, and preference and intake frequency of processed foods. All subjects were classified based on monthly allowance: less than \300,000 (n=149), \300,000~400,000 (n=177), and more than \400,000 (n=124). All survey results were comparatively analyzed among the spending money groups. As the level of spending money of the subjects increased, the rate of skipping meals, eating out, and unbalanced diet increased (P<0.05). The reason for consuming processed foods was because they are easy to prepare. The factor considered the most when buying processed foods was price. However, these results showed no significant difference according to level of spending money. As spending money increased preference for retort, convenience, canned, and bottled foods significantly increased. Intake frequency of dairy products was lower, and the frequency of processed foods was significantly higher with more spending money. This study found that a higher level of monthly allowance in college students, was associated with higher rate of skipping meals, eating out, and unbalanced diet, and the preference and intake frequency of processed foods were also high. These results suggest that spending money level in college students, as an economic indicator, is relevant to intake of processed foods.

BACKGROUND/OBJECTIVES: Metabolic syndrome is closely associated with lifestyle factors, including diet and nutritional intake. Modern trends show a shift in food consumption from healthy home-cooked meals to processed and instant foods. Therefore, this study analyzed the association between ultra-processed food intake and the development of metabolic syndrome in Korean adults based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2013-2018. SUBJECTS/METHODS: The subjects of this study were 17,414 adults aged 19-80 years who participated in the 6th-7th KNHANES. Processed food was classified into four categories, NOVA1 to NOVA4, using 24-h recall data. The higher the NOVA category, the more processed the food. Statistical analysis was conducted using logistic regression to investigate the prevalence of metabolic syndrome according to the consumption of ultra-processed foods. RESULTS: Among the diagnostic criteria for metabolic syndrome, hypertension (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.62-0.85; Q4 vs. Q1, P-trend < 0.001) and high triglycerides (OR, 0.83; 95% CI, 0.72-0.94; Q4 vs. Q1, P-trend < 0.001) showed a correlation with the percentages of energy consumed from ultra-processed foods. The OR for metabolic syndrome, according to the percentages of energy consumed from ultra-processed foods, is shown only for men. The OR showed that the percentages of energy consumed from ultra-processed foods were associated with increased metabolic syndrome. CONCLUSIONS: This study suggests that consumption of ultra-processed foods raises the risk of metabolic syndrome especially among men. To prevent metabolic syndrome, it is necessary to prepare appropriate dietary guidelines for Korean adults.
