Research on the actual state of healthy Korean food menu items made from environmentally-friendly organic foods showed that 65.6% of subjects had experience of purchasing environmentally-friendly organic foods, and both genders chose 'expensive but reliable' as their prime reason for purchasing. Having no experience of purchasing environmentally-friendly foods constituted 34.5% of respondents, and the reasons were 'high price' and 'finding no difference from ordinary food'. Research on awareness of healthy Korean food menu items made from environmentally-friendly organic ingredients showed that both men and women thought the given menu items were 'fresh' but had little awareness of other factors such as 'good value for price', 'good visual style' and 'various recipes'. Regarding development prospective of environmentally-friendly organic foods, the number of subjects who answered positively was 405 (93%), which indicates that most research subjects showed positive attitudes. Top-selling menu items in the grain section were Sundubu-jjigae, Dubu-kimchi and Jeonju-bibimbap, and pajeon took first place in the vegetable selection. Moreover, Imjasu-tang showed high scores in the meat section. Furthermore, research on menu selection showed that menu selection was usually dependent on 'the price of menu (3.86)', 'fresh ingredients (4.03)', 'harmony of color (3.65)' and 'mood of the day (3.25)'. Research on menu selection revealed that 'quality of food' factors had the greatest influence upon preference and purchase intention for environmentally-friendly organic foods. Visual and psychological factors and values had significant an effect. Therefore, the food service industry should use this study as a source to develop menu items, by considering quality and visual factors. In addition, there should be various research performed on marketing strategies about menus from using environmentally-friendly organic foods and high value products.

BACKGROUND/OBJECTIVES: While plate waste has been widely investigated in hospitals, there have been minimal studies specific to the texture-modified diet (TMD). This study aims to determine the percentage of plate waste among patients prescribed with TMD and its contributory factors. SUBJECTS/METHODS: This was a single-centre study conducted in the university hospital on three types of TMD (blended diet, mixed porridge, minced diet) during lunch and dinner meals. Weighing method and visual estimation method assisted by digital photograph were adopted in this study. Face to face interview was carried out to investigate on 1) the food/food service quality factors in terms of patients' satisfaction level towards sensorial quality of food and food services provided and 2) the clinical/external factors including appetite, the provision of oral nutrition support, time taking the diet, the need for feeding assistance and the length of hospital stay. RESULTS: The mean percentage of overall plate waste of 95 patients receiving TMD was high (47.5%). Blended diet was identified as the most wasted diet (65%) followed by minced diet (56%) and mixed porridge (35%). Satisfaction level among patients was moderate. Patients on TMD in general had higher satisfaction level on the aspect of food service as compared to food quality. Substantial association between sensorial qualities of food and plate waste were varied according to individual TMD type. A multiple linear regression showed that only the satisfaction level toward the aspects of appearance and variety of foods were the predictors of TMD plate waste (R² = 0.254, P < 0.05). CONCLUSIONS: A significant relationship between the percentage of plate waste and the overall satisfaction level of patients receiving TMD suggests that vigorous strategies are needed to reduce the food waste of TMD which will lead to a better nutritional status and clinical outcomes among the patients.

The purpose of this study was to explain consumption experience of vitamin/mineral, aloe, calcium, red ginseng and glucosamine. It also explains influencing factors such as health related factors(importance of healthy eating, perceived role of food for health, health motivation), consumer attitude of healthy functional foods(reward from using healthy functional foods, confidence in functional foods) and individual characteristics(age, sex, education, income) on them. To do this, LIMDEP program was applied to estimate the logit model. The results of this study were as follows: 1) The levels of health motivation, reward and confidence from using healthy functional foods were found to be relatively low, while the levels of importance of healthy eating and the perceived role of food for health were found to be relatively high. It might imply that consumers would have some interest for health and food consumption. Also consumers expressed to have some experience for vitamin/mineral(50%), aloe(16%), calcium(23%), red ginseng(40%) and glucosamine(17%). 2) For influencing factors, age was found to be significantly influential to all of the products. If consumers were getting older, they were more likely to consume the products. In addition, reward from using healthy functional foods was found to significantly influence consumption experience of vitamin/mineral and calcium. If consumers perceived more reward from using vitamin/mineral and calcium, they were more likely to consume the products. For aloe, confidence in healthy functional foods was found to significantly influence consumption. Furthermore, sex was found to be a significant factor for consumption of vitamin/mineral.

The purpose of this study was to examine the mediating role of nausea, learned food aversion, and appetite on the relationship between food neophobia and food rejection. A total of 250(122 healthy males and 128 healthy females) questionnaires were completed. Path analytic model was used to measure the mediating effect. Results of the study demonstrated that the path analytic result for the data also indicated excellent model fit. Furthermore, the mediating analysis indicated that the influence of food neophobia was mediated by mediator. The effect of food neophobia on appetite was perfectly mediated by nausea and learned food aversion. In the contests of general food rejection, the effect of food neophobia on food rejection was perfectly mediated by appetite. It should be noted that the original model was modified and should, preferably, be validated in future research.

The purpose of this study was to compare food intakes between Korean breast cancer patients and a healthy control group. We compared the intake of nutrients of 117 food items between Korean breast cancer patients (n=97) and age matched healthy controls (n=97). Nutrient intake was estimated using a quantitative food frequency questionnaire. The mean caloric intake of breast cancer patients and healthy controls was not significantly different. Breast cancer patients consumed significantly less fat and antioxidant nutrients such as vitamin A, retinol, ${\beta}-carotene$, vitamin C and vitamin E when compared to the control subjects. Among the food items, the intake of eggs (p<0.01), legumes (p<0.05), vegetables (p<0.05), seasonings (p<0.001), and oils and fats (p<0.01) in breast cancer patients was significantly lower than that in the controls. These results suggest that Korean breast cancer patients consumed less amount of soy and vegetables, which are rich source of antioxidant nutrients and phytosterols. Thus, dietary guidance to increase intake of these foods may be beneficial in the prevention of breast cancer.

Caffeine is widely consumed and well known for stimulating the central nervous system. When developing new foods and beverages that contain caffeine, it is important to explore the potential synergistic effects of consuming amino acids and other food ingredients with caffeine on humans. Given the physiological pathways affected by the amino acid ornithine, consumption of ornithine with caffeine may have synergistic effects. The purpose of the present study was to examine the effect of consuming caffeine with ornithine in humans. The study used a randomized, placebo-controlled, double-blinded crossover design. The subjects were all healthy office workers who ingested the placebo, 100 mg caffeine, or 100 mg caffeine plus 200 mg ornithine in the morning and completed questionnaires about their mood. Office workers who consumed the combination of caffeine and ornithine had higher mood ratings 8 h after consumption than office workers who consumed caffeine alone. The results of the present study suggest that there is a unique synergistic effect between caffeine and ornithine on the mood of healthy office workers and that ornithine may potentiate the effects of caffeine.

본 연구는 서울 및 경기지역에 거주하는 노인 250명을 대상으로 건강기능식품 섭취가 식생활에 미치는 영향을 파악하기 위해 수행되었다. 2주 이상 지속적으로 건강기능식품을 섭취하였을 때 건강기능식품 섭취군으로 판정하였고, 노인의 식생활 평가를 위해 구성타당도 평가가 수행된 노인 영양지수 (NQ-E 2021)를 활용하여 식사의 질을 평가한 결과는 다음과 같다. 본 연구대상자의 평균 연령은 70.8세이었고, 건강기능 섭취 여부에 따른 연령, 키, 체중 및 체질량지수에 유의적인 차이는 존재하지 않았다. 전체 조사대상자의 NQ-E 점수와 영역별 점수를 보면 NQ-E 52.5점, 균형 43.3점, 절제 56.7점, 실천 65.7점이었고, 영양지수 전체 17개 항목 중 60점 이하의 낮은 점수를 보인 항목은 총 7개였는데, '과일 섭취', '우유 및 유제품 섭취', '어패류 섭취', '달걀 섭취', '콩 및 콩 제품 섭취', '견과류 섭취'와 '단 간식 및 단 음료 섭취 절제' 점수가 낮아서 노인들이 전반적으로 다양한 식품군을 충분하게 섭취하지 못하는 것으로 평가되었다. 건강기능식품 섭취 여부에 따른 차이를 보면 전체 NQ 점수와 다양한 식품군을 섭취하는 균형점수에서 유의적인 차이를 보여 건강기능식품 섭취군에서 건강기능식품 비섭취군보다 유의적으로 높은 점수를 보였다. NQ 판정등급 비율에서도 건강기능식품 섭취군이 건강기능식품 비섭취군보다 NQ-E 점수와 균형 영역에서 [상] 등급이 8% 이상 유의적으로 더 많았다. 영양지수 문항별 점수에서 건강기능식품 섭취군은 과일, 어패류, 달걀, 견과류, 잡곡밥 섭취 및 건강한 식생활을 하려는 노력에서 건강기능식품 비섭취군보다 높은 점수를 보였다. 본 연구결과 노인에서 건강기능식품 섭취군이 비섭취군보다 영양지수 평가를 통해 전반적인 식사의 질이 높은 것으로 평가되었는데, 이는 건강기능식품 섭취군에서 균형과 실천 영역에 해당하는 문항의 점수가 높은 것에 기인하였다. 그러나 전반적으로 노인들의 영양지수 점수가 낮고, 특히 균형 영역에 해당하는 다양한 식품군의 섭취가 제대로 이루어지지 않으므로 노인 영양문제 개선을 위한 지속적인 노력이 강구되어야 할 것으로 사료된다.

BACKGROUND/OBJECTIVES: Obesity is a serious concern worldwide, for which the restaurant industry holds partial responsibility. This study was conducted to estimate restaurant consumers' intention to select healthy menu items and to examine the relationships among behavioral beliefs, past behaviors, attitudes and behavioral intentions, which are known to be major determinants of consumer behaviors. SUBJECTS/METHODS: An online, self-administered survey was distributed for data collection. The study sample consisted of customers who reported having visited casual dining restaurants in the last three months at the time of the survey. Structural equation modeling was used to verify the fit of the proposed research model. RESULTS: Structural equation modeling revealed that the proposed model supports the sequential, mediated (indirect) relationships among behavioral beliefs, past behaviors, attitudes and behavioral intentions toward healthy menu selection. CONCLUSION: This study contributes to the available literature regarding obesity by adding past behaviors, one of the most influential variables involved in prediction of future behaviors of consumers, to the TPB model, enabling a better understanding of restaurant consumers' rational decision process regarding healthy menu choices. The results of this study provide practical implications for restaurant practitioners and government agencies regarding ways to promote healthy menus.

Objectives: The purpose of this study was to analyse the relationship between eating behaviour and healthy dietary competency of single and multi-person households, to improve healthy eating behavior. Methods: This study was conducted on 6,355 adult household members who participated in the Food Consumption Behavior Survey 2020. The subjects were divided into age groups comprising young people in their 20s and 30s, middle-aged people in their 40s and 50s, and the elderly in their 60s and above. The eating behavior and healthy dietary competency of single-person and multi-person households were then analyzed. Results: The average age of the members in the single-person households was found to be higher. Single-person households were also found to have a lower marriage rate and lower monthly household income than multi-person households across the age groups of young, middle-aged, and elderly people (P < 0.05). Among each of the age groups, single-person households had significantly higher rates of skipping breakfast and eating breakfast, lunch, and dinner alone than multi-person households (P < 0.05). Young single-person households had lower average scores on healthy dietary competency than multi-person households (P = 0.032). When adjusted for age, gender, marriage, education, occupation, and household income, single-person households had a higher risk of delivery/take-out, eating out, or skipping meals compared to multi-person households (P < 0.05). In multi-person households, the risk of skipping meals, eating alone, eating out, or delivery/take-out decreased as healthy dietary competency improved (P < 0.05). On the other hand, in single-person households, as healthy dietary competency increased, the risk of delivery/take-out or eating alone decreased (P < 0.05). Conclusions: The results of this study suggest that healthy dietary competency and eating practices can be improved by providing customized dietary education by age group for single and multi-person households.
