[CURRENT STATUS OF FOOD ALLERGY MANAGEMENT IN FOOD SERVICE PROVIDERS].

OBJECTIVE: Assess the current state of food allergy management strategies and the perceptions of them among food service providers. METHODS: The study surveyed establishments that participated in a food allergy management workshop or- ganized by the Tokyo Metropolitan Government in February 2018. The survey inquired about the implemen- tation status of food allergy management strategies, the frequency of accidental ingestions and near misses, and the necessary actions for advancing food allergy management. RESULTS: The survey yielded a response rate of 78% (257/331); 81% of the operators reported having implemented some form of food allergy management strategies. However, only 51% had created a manual for food allergy management and 55% had labeled 7 specified ingredients. 29% of the operators reported experiencing accidental ingestions or near misses, with 34% of those incidents requiring medical attention. 49% of the operators identified the "establishment of industry standards" as a crucial step in advancing food allergy management. CONCLUSION: The survey results indicate that establishments have not fully implemented adequate and effective food allergy management strategies. There is a need to enhance the awareness and understanding of food allergies among businesses and to establish appropriate and sufficient food allergy management measures in the future.

What influences restaurant dining out and diners' self-protective intention during the COVID-19 pandemic: Applying the Protection Motivation Theory.

In this study, using the Protection Motivation Theory (PMT), we examine whether protection motivation can explain restaurant patron intention to practice self-protection. New normal practices are in place in the restaurant industry that influence dining out behavior during the COVID-19 pandemic. Based on 402 usable questionnaires collected face to face with residents in Phuket, Thailand, and using structural equation modeling to analyze the data, we found self-protective intention is influenced more by the perceived threat of COVID-19, but the actual behavior of visit frequency and protective behavior is influenced more by the positive PMT factors: perceived efficacy or self-confidence about protecting oneself and the expected rewards of dining out. In addition, the study highlights the important role of self-protective intention as a mediator in the relationships between PMT factors and actual behaviors of restaurant clients, especially their protection behaviors. Academic and practical implications are discussed.

[Eating out of home of urban adults in eighteen provinces (autonomous regions, municipalities) of China in 2017].

OBJECTIVE: To analyze the eating out of home behavior of urban adults in China. METHODS: Samples were chosen from China Food Consumption Survey in 2017. A total of 17 234 participants aged 18 and above were included in the final analysis. The food frequency questionnaire were used to collect eating out of home status in the past week. χ~2 test was used to compare the difference in the rate of eating out of home and dining places among different groups. Non-parametric test was used to compare the differences in dining out times. RESULTS: The overall prevalence of eating out of home was 55.6% in urban adults aged in 2017. The average number of eating out of home was 2.8 times. The proportion of eating in hotels and restaurants was 36.0%. The proportion of eating in the canteen of school, workplace and other places was 19.8%. The rate of eating out of home and dining out times were higher among male, 18-44 years old, people with higher educational level and higher household income. The proportion of students eating in canteen was higher. The proportion of professional technicians and service staff eating in hotels and restaurants were higher. CONCLUSION: Eating out of home is more common among urban adults aged 18 and above in China. Young people aged 18-44 years old eat out more often in the past week. The proportion of people eating in hotels and restaurants is higher.

A practical solution to improve the nutritional balance of Korean dine-out menus using linear programming.

OBJECTIVE: We analysed optimal nutrient levels using linear programming (LP) to reveal nutritional shortcomings of Korean dine-out meals and to stress the importance of fruits and dairy products for maintaining a healthy diet. DESIGN: LP models that minimize deviation from recommended nutrient values were formulated to analyse deficiency or excess of nutrients under the best situation. SETTING: Korean dine-out menus and nutritional information were taken from the nutrient composition tables for dine-out menus developed by the Ministry of Food and Drug Safety and the nutrient database from Computerized Analysis Program. Acceptable macronutrient distribution ranges of macronutrients such as carbohydrate, protein and fat, and recommended intake levels for energy, vitamins, minerals and cholesterol, by sex, were based on the Dietary Reference Intake for Koreans aged 30-49 years.ParticipantsOptimization was performed on selecting the optimal Korean meal combination. RESULTS: LP optimization models showed that it is unlikely to satisfy all nutrient recommendations with any combination of dine-out menus. Specifically, meal combinations of Korean dine-out menus had high levels of Na and cholesterol and low levels of vitamins and minerals. Four formulations were considered to compare the effects of controlling Na and including fruit and dairy products. The unbalanced diet was resolved with extra consumption of fruits and dairy products. CONCLUSIONS: The best meal combination in dine-out menus, even though the proportion and pairing of menus may be unrealistic, is not healthy, and thus one should consume fruits and dairy products to maintain a balanced diet.

Association between the Frequency of Dining Out and the Risk of Obesity, Diabetes Mellitus, and Dyslipidemia among Korean Adults.

This study aimed to clarify the association between the frequency of dining out and the risk of obesity, diabetes mellitus, and dyslipidemia among Korean adults. This cross-sectional study surveyed 640 participants aged 20-69 years in Korea. Daily intake of energy, fat, protein, and cholesterol significantly increased as the frequency of dining out increased (P < .001). Energy derived from carbohydrates significantly decreased with the frequency of dining out, while that derived from fat and protein increased (P < .001). Among participants who rarely dined out, the fully adjusted odds ratios (ORs) for hyperglycemia were significantly lower at 0.35 (95% CI, 0.16-0.76). Decreased risk of being hyperglycemia among participants who rarely dined out suggests that the frequency of dining out can be related to diabetes risk.

[Study on breakfast consumption of children aged from 6-17 in China in 2010-2012].

Objective: To investigate breakfast status and influencing factors among children aged 6-17 in China in 2010-2012. Methods: Data were collected from China National Nutrition and Health Surveillance in 2010-2012. By using multi-stage stratified sampling and population proportional stratified random sampling method, the research objects were 29 393 children, who aged 6 to 17 y from 150 sites in 31 provinces in mainland China. The information of breakfast frequency and the numbers of breakfast dinning out (in restaurant and at schools) in the past week with seven days were collected by questionnaire; and compared by different ages, genders and areas. Results: During the past week, 91.1% (26 776/29 393) of the children aged 6 to 17 y had their breakfast daily, and 94.6% (13 457/14 221) of children aged 6 to 11 y was higher than 87.8% (13 319/15 172) of children aged 12 to 17 y, the highest proportion of the children never eat breakfast (0 time in the past week) found in poor rural areas was 3.6% (189/5 261), the ratio of big cities, small-medium cities and normal rural areas was 1.1% (77/7 104), 0.6% (51/8 361), and 0.6% (54/8 667), respectively (P<0.001). The rate of boys and girls ate their breakfast daily in the past week were 91.3% (13 481/14 761), and 90.9% (13 295/14 632), respectively (P>0.05). Totally 42.2% (12 398/29 393) of children ate breakfast outside-home (the restaurant and the school) in the past week, the percentage of children aged 12 to 17 y and poor rural areas was higher, 50.9% (7 722/15 172), and 52.4% (2 756/5 261), respectively (P<0.001). 42.1% (6 208/14 761) boys and 42.3% (6 190/14 632) girls ate their breakfast outside-home (P>0.05). The place of most school-age children eat outside-home was school, the ratio was 32.2% (9 477/29 393). Conclusion: It was common for school-aged children in China to skip breakfast during their daily lives, especially in poor rural areas and older children, lots of school-aged children ate breakfast outside-home, and most of them ate breakfast in school.

The COVID-19 Pandemic, Rising Inflation, and Their Influence on Dining Out Frequency and Spending.

BACKGROUND: High intake of food away from home is associated with poor diet quality. This study examines how the COVID-19 pandemic period and Food Away from Home (FAFH) inflation rate fluctuations influenced dining out behaviors. METHODS: Approximately 2800 individuals in Texas reported household weekly dining out frequency and spending. Responses completed prior to the COVID-19 pandemic (2019 to early 2020) were compared to the post-COVID-19 period (2021 through mid-2022). Multivariate analysis with interaction terms was used to test study hypotheses. RESULTS AND CONCLUSION: From the COVID-19 period (before vs. after), the unadjusted frequency of dining out increased from 3.4 times per week to 3.5 times per week, while the amount spent on dining out increased from $63.90 to $82.20. Once the relationship between dining out (frequency and spending) was adjusted for FAFH interest rate and sociodemographic factors, an increase in dining out frequency post-COVID-19 remained significant. However, the unadjusted increase in dining out spending did not remain significant. Further research to understand the demand for dining out post-pandemic is warranted.

Effect of restaurant consumers' anticipated emotions on perceived value and behavioral intention in the COVID-19 context.

While hospitality scholars have been conducting research on post-pandemic consumption recovery, the impact of the psychological consequences of COVID-19 on consumers' post-pandemic behavior remains insufficiently addressed. Therefore, the purpose of this study is to explore the relationships among anticipated emotions, perceived value, perceived threat, and dining-out intention in the COVID-19 context. In this study, 621 restaurant consumers in China were surveyed and the data were analyzed with structural equation modeling. The results suggested that positive anticipated emotions affect perceived hedonic, utilitarian, and social values, whereas negative anticipated emotions affect hedonic value. Hedonic and utilitarian values then influence dining-out intention. Perceived threat in terms of perceived severity and susceptibility to COVID-19 was explored to moderate the impacts of hedonic and social values on the intention. This study contributes to the literature by identifying the positive, distinct roles of both anticipated emotions on consumer dining-out intention through perceived values and threats during the early recovery of COVID-19.

Analysis of Food Delivery Using Big Data: Comparative Study before and after COVID-19.

This study examined consumers' change in perception related to food delivery using big data before and after the COVID-19 crisis. This study identified words closely associated with the keyword "food delivery" based on big data from social media and investigated consumers' perceptions of and needs for food delivery and related issues before and after COVID-19. Results were derived through analysis methods such as text mining analysis, Concor analysis, and sentiment analysis. The research findings can be summarized as follows: In 2019, frequently appearing dining-related words were "dining-out," "delivery," "famous restaurant," "delivery food," "foundation," "dish," "family order," and "delicious." In 2021, these words were "delivery," "delivery food," "famous restaurant," "foundation," "COVID-19," "dish," "order," "application," and "family." The analysis results for the food delivery sentimental network based on 2019 data revealed discourses revolving around delicious, delivery food, lunch box, and Korean food. For the 2021 data, discourses revolved around delivery food, recommend, and delicious. The emotional analysis, which extracted positive and negative words from the "food delivery" search word data, demonstrated that the number of positive keywords decreased by 2.85%, while negative keywords increased at the same rate. In addition, compared to the pre-COVID-19 pandemic era, a weakening trend in positive emotions and an increasing trend in negative emotions were detected after the outbreak of the COVID-19 pandemic; sub-emotions under the positive category (e.g., good feelings, joy, interest) decreased in 2021 compared to 2019, whereas sub-emotions under the negative category (e.g., sadness, fear, pain) increased.

Delivering the Multisensory Experience of Dining-Out, for Those Dining-In, During the Covid Pandemic.

In many parts of the world, restaurants have been forced to close in unprecedented numbers during the various Covid-19 pandemic lockdowns that have paralyzed the hospitality industry globally. This highly-challenging operating environment has led to a rapid expansion in the number of high-end restaurants offering take-away food, or home-delivery meal kits, simply in order to survive. While the market for the home delivery of food was already expanding rapidly prior to the emergence of the Covid pandemic, the explosive recent growth seen in this sector has thrown up some intriguing issues and challenges. For instance, concerns have been raised over where many of the meals that are being delivered are being prepared, given the rise of so-called "dark kitchens." Furthermore, figuring out which elements of the high-end, fine-dining experience, and of the increasingly-popular multisensory experiential dining, can be captured by those diners who may be eating and drinking in the comfort of their own homes represents an intriguing challenge for the emerging field of gastrophysics research; one that the chefs, restaurateurs, restaurant groups, and even the food delivery companies concerned are only just beginning to get to grips with. By analyzing a number of the high-end fine-dining home food delivery options that have been offered (in the UK and in the US) in this narrative review, we highlight a number of promising directions for those wanting to optimize the at-home multisensory dining experience, wherever in the world they might be.

Characteristics of Food Allergic Reactions in United States Restaurants.

BACKGROUND: Food allergic reactions of varying severity occur in restaurants. Studies to date have shown that there are gaps in knowledge of and communication between restaurant staff and food allergic individuals. OBJECTIVE: We sought to characterize allergic reactions in restaurants to better inform the restaurant industry, food allergic individual, and allergist so that mitigation strategies can be implemented. METHODS: Data collected over a 2-year period from 2822 individuals in the Food Allergy Research & Education registry were analyzed using descriptive statistics. RESULTS: Dining out accounted for the second most common location for a food allergic reaction, after one's home, and many were severe with 28.0% requiring 1 dose and 6.2% requiring 2 doses of epinephrine. Cafes, fast food establishments, and Asian restaurants were frequently implicated sites. Peanut, tree nuts, and milk were the most common inciting allergens, and tree nuts resulted in the most common use of epinephrine. Of the allergic reactions, 53.9% occurred despite conveyance of food allergy to restaurant staff, 26.6% occurred when allergens were declared on the menu, and 13.7% occurred when allergens were declared on the menu and restaurant staff were informed of a food allergy. CONCLUSIONS: Allergic reactions in restaurants are common and can be severe. Findings presented here underscore the need for restaurant staff training and mandatory declaration of allergenic ingredients in meals. This updated knowledge will help support advocacy efforts and inform patients, allergists, and the restaurant industry on best practices for dining out to improve the quality of life for food allergic individuals.

Food Allergy in Restaurants Work Group Report.

Individuals with food allergy are at risk for accidental exposures, potentially resulting in allergic reactions that may cause significant morbidity and mortality. Dining out, including restaurants or take-out, account for a large proportion of severe reactions. Errors due to gaps in knowledge or miscommunication can easily occur on behalf of food-allergic individuals or restaurant staff, resulting in accidental exposures and allergic reactions. Improved legislation, training of restaurant staff, and practitioner-guided education are recommended to reinforce patient safety and prevent severe allergic reactions. This Work Group Report provides guidance with specific practices that practitioners may recommend, and that patients and restaurant staff may employ, for prevention and treatment of food-allergic reactions in restaurants.

Study on the Use of Cooking Oil in Chinese Dishes.

The purpose of this study was to research the amount of cooking oil used in mainstream Chinese cuisine, as well as the features of cooking oil used in different types of dishes. The results provide reference data for the assessment of edible oil intake for eating out. A total of 302 common Chinese dishes were chosen and prepared following standard procedures. The cooking oils used in these dishes were analyzed in terms of the cooking process, food material combination, types of primary food materials, type of cooking oil, and the purpose of the cooking oil. The results showed that the mean amount of cooking oil used per 100 g of food material was 8.1 g. There were no significant differences in the amount of cooking oil used in the eight major styles of Chinese cuisine. The average amount of cooking oil used in hot dishes (10.0 g) was higher than that used in cold dishes. The amount of cooking oil in pure meat, mixed meat-vegetable, and pure vegetable dishes was up to 10.9 g, 9.3 g, and 4.6 g, respectively. The findings of the present study could be used in future dietary surveys to determine the average oil consumption associated with different dishes. In addition, the results provide reference data for oil intake assessments in nutrition surveys or nutritional recipes.

Interventions to promote healthy eating choices when dining out: A systematic review of reviews.

PURPOSE: To synthesize review research pertaining to the effectiveness of interventions in dining-out settings to reduce food/calorie consumption. METHODS: A rapid review methodology was employed to focus on synthesized research. A comprehensive search for peer-reviewed systematic reviews from 2010 to 2015 yielded 1,847 citations. Following screening, ten systematic reviews were included. RESULTS: The 10 included systematic reviews identified 183 primary studies evaluating evidence in three behavioural intervention areas: social models/norms, manipulation of size, and provision of health information. Three systematic reviews evaluating the use of social models/norms found this was an effective intervention for influencing food intake. Five systematic reviews that assessed manipulation of portion/dishware/cutlery size found a small-to-moderate effect on food consumption. Three systematic reviews looked at the provision of health information, which was not effective alone; however, in combination with contextual or interpretive material such as traffic lights or exercise equivalence, this was shown to reduce calorie consumption. One systematic review covered two topic areas. CONCLUSIONS: The results indicate that policies or interventions that aim to improve healthy choices or consumption when dining out would benefit from harnessing social norms and positive positioning of social identity. Furthermore, provision of health information should always be accompanied by an interpretative guide, such as traffic lights. Manipulation of plate/portion/cutlery size may be effective; however, the effect size is small and further research is required to investigate whether this effect is retained in overweight or obese populations. Statement of contribution What is already known on this subject? Eating behaviours (food choices, consumption) have played a role in the obesity epidemic. Behavioural 'nudges' have tried to increase healthier eating choices. What does this study add? Social norms and modelling have a strong influence in both directions on how much people consume. Provision of nutritional information needs to be paired with interpretative aids (e.g., traffic lights). Manipulation of portion size is less effective in overweight populations.

Dining-out behaviors of residents in Chuncheon city, Korea, in comparison to the Korean National Health and Nutrition Survey 2001.

Dining-out behavior is associated not only with socio-demographic characteristics such as gender, education, occupation, residence, and marital status, but also with individual preferences, such as eating-out activities, interests, and opinions. We investigated dining-out behaviors and their associated factors. Announcements by health practioners and the Chief of Dong Office were used to recruit 739 residents (217 males and 522 females) in Chuncheon, Korea. Information on the frequency and reasons for eating out, the standards for meal selection, and the overall satisfaction with restaurants, based on taste, nutrition, amount, price, service, sanitation, and subsidiary facilities of restaurants, was obtained through personal interviews with a structured questionnaire. Among all respondents, 46.3% of subjects ate outside of the home once or twice a month, and 33.8% reported that they ate out only a few times a year, or never. This was much higher than the national average of 52.0% as reported by the Korean National Health and Nutrition Survey (KNHNS) in 2001. The frequency of eating out differed significantly according to age (p=0.001), family income (p<0.001), residential area (p<0.001), and educational level (p<0.001). The most common reasons for dining out were meetings (46.7%), followed by special celebrations (15.4%), and enjoyment (11.2%). Korean food (55.3%) was the most frequently selected type of meal when eating out, and food was most often selected based on personal preferences (41.4%) and taste (29.8%); only 5.5% and 7.7% of subjects considered nutrition or other factors (e.g., sanitation), respectively. The results showed that the frequency of eating out for Chuncheon residents was much lower than the national average; in addition, eating-out behaviors depended on the residents' socio-demographic and personal characteristics.
