The principal objective of this study was to assess the bone density and processed food intake behavior of middle-aged and elderly women in the Seoul area. The subjects were assigned to one of the following groups on the basis of BMI: namely, the underweight, normal, and overweight groups. The results are summarized as follows: The average BMI and systolic blood pressure of the three groups were 19.0, 127.3 mmHg; 22.4, 132.8 mmHg; and 26.8, 136.1 mmHg respectively. The BQI and T-scores of the three groups were as follows: 56.6, -2.50; 62.3, -2.22; 66.0, -2.03 respectively. The bone status of the three groups, in terms of the percentage of normal and osteoporosis, were 9.5%, 52.4%; 8.3% 33.0%; and 8.8%, 23.6% respectively. We noted no significant differences in processed food intake (frozen, cold and can processed food, instant and convenience store food, basic side dishes) behavior among the three groups. However, we recorded a negative value between processed food intake and bone density (BQI, T-score, %young adult, Z-score, %age-matched) generally. In particular, ramyeon (r=-0.1574, p<0.05) and cup-ramyeon (r=-0.1996, p<0.05) intake were significantly associated with the T-scores of bone density levels. The results of this study revealed that processed food intake was not generally desirable for healthy bone. Thus, practically and systematically organized education regarding a good and healthy dietary life is highly recommended.

This study investigated changes in the quality of fermented red snow crab Chionoecetes japonicus sauce with or without Aspergillus kawachii koji and added salt. Samples were divided into four groups depending on whether koji was added and the amount of salt: RC15, 15% added salt, no koji; RC20, 20% added salt, no koji; RK15, 15% salt plus 10% koji; and RK20, 20% salt plus 10% koji. The samples were fermented at 20±2℃ for 4 months. During the fermentation period, the moisture contents of the four types of sauce decreased while the crude ash and protein contents increased. The pH of the RK groups decreased and was lower than in the RC groups. The acidity of the RK groups increased and was higher than in the RC groups. Both the total nitrogen (TN) and amino nitrogen (AN) levels increased continuously and were higher in the RK groups than in the RC groups. The volatile basic nitrogen (VBN) content increased rapidly and was higher in the RC groups than in the RK groups. The color did not differ significantly among the four groups. The viable cell counts in the four groups increased and no coliforms were detected. The total free amino acid and glutamic acid contents were highest in the RK15 group and the main amino acids in RK15 were aspartic acid, glutamic acid, alanine, leucine, phenylalanine, and lysine. Overall acceptance was significantly higher for the RK groups than the RC groups and RK15 ranked highest among the four sauces. These results suggest that Aspergillus kawachii koji is beneficial for processing fish sauce made using red snow crab.

This study aims to empirically analyze the differences between groups of customers who prefer delivery food, which is rapidly growing amid the COVID-19 pandemic, and those who prefer the traditional practice of visiting offline restaurants. Based on the eating out lifestyle, participants were divided into three groups: participants who prefer food delivery, those who prefer to visit restaurants, and those who favor both. The comparison of differences between the groups was analyzed. A total of 215 questionnaires were distributed, and reliability and validity were verified with a sample of 201 copies, excluding 14 unreliable respondents. Then, a multivariate analysis of variance was used to compare the groups. The results showed that regarding offline restaurants, the group of customers who prefer to visit restaurants valued their atmosphere, while the customers who prefer delivery food valued the reputation of the restaurant. Regarding delivery-specialized restaurants, the group of customers who prefer delivery placed greater value on coupon events and payment convenience than other groups. The results revealed that the difference between the customers who prefer to visit restaurants and those who prefer delivery food was identified through empirical analysis, which provides strategic implications for catering companies and restaurant industries during COVID-19 in Korea.

The purpose of this study was to investigate the health status and food habits of male college students in Seoul according to drinking habits. In order to identify risk factors, health surveys were conducted from October 2013 to December 2013. Average height, weight, and BMI of subjects were $175.47{\pm}5.27cm$, $67.93{\pm}9.28kg$, and $22.04{\pm}2.67kg/m^2$, respectively. Weight and BMI were higher in the non-drinking groups compared to the drinking groups (p<0.05). Frequency of drinking was 2~3 times per month, and 52.4% of subjects started drinking when starting university. The motivation to start drinking was cited as "From necessity". Reason for drinking was "Social relations". The favorite kind of drink was beer. Rate of taking supplements was 24.4% of the subjects. Vitamin preparations were highest in drinking groups and non-drinking groups (p<0.05). The reasons for skipping meal were "too busy" in the drinking groups, and "oversleep" in the non-drinking groups (p<0.05). The preference for snacking in drinking groups were milk, milk products, and fast food, with the highest being listed first. The non-drinking groups preferred carbonated drinks and ice cream. The drinking groups need more education about their drinking habits. Drinking groups also need an increased intake of vegetables and fruits.

A dietary survey was conducted using 24-hour recall method in 80 male elementary school children, 83 high school students, 87 adults and 98 elderly people over 65 years of age to discuss food and nutrient intakes among different age groups. In observing food intake by age groups, the percentage of plant foods to total food intake was significantly higher in the elderly than other groups and that of animal foods was the highest in the children. The children consumed significantly higher amounts of milk and dairy products. Carbohydrate energy percent in the elderly people was 68.0%, significantly higher than other age groups. All age groups consumed Ca below Korean RDA and especially, 65.1% of the adolescents and 68.4% of the elderly consumed below 75% of RDA. Nutrient adequacy ratio (NAR) of most nutrients was lowest in the elderly. Mean adequacy ratio (MAR), an index of overall dietary quality, was 0.94 for the children, 0.84 for the adolescents, 0.84 for the adults, and 0.73 for the elderly. The above results suggest that food and nutrient intakes have been differently affected with advancing age, and overall dietary quality of the elderly people is lower than that of other age groups.

The purpose of this study was to compare weight control behaviour, eating habits, and health-related life habits according to degree of obesity among normal, overweight, and obese groups. Self-perception of weight and desire for weight control in males (p<0.001) and females (p<0.001) varied among the three groups. Reasons (p<0.001), experience (p<0.01), and method of weight control (p<0.05) were different among the three female groups, whereas males did not show any differences. Intake of nutritional supplements in the male obese group was higher compared to other groups (p<0.01), whereas eating habits were not significantly different among the three groups for both males and females. Food habits score for intake of fruits, milk, and yogurt were higher in females than males (p<0.001). Correlation coefficients of food habits score and anthropometric measurements showed that hip circumference was negative for intake of fruits in males, whereas RBW and BMI were positive for food combination, intake of bean products, and fishes in females (p<0.05). Frequency and fitting exercise in the obese female group were lower than in the other groups (p<0.01). Therefore, proper nutritional education for obese individuals is recommended proper self-perception of weight, good food habits, and regular exercise.

Malaysia is regarded as one of the leaders in the global halal marketplace, which has undergone huge growth in the past few years. The aims of this study were to identify imported food consumers in Malaysia based on Food Related Lifestyle (FRL) attributes and to investigate the demographic characteristics and purchasing behaviors of each segmented groups. Using an online survey, a total of 600 responses were collected in Malaysia. Excluding invalid responses, cluster analysis segmented imported food consumers into four FRL groups: impulsive, high interest, low interest, and traditional consumers. The results of this study were as follows. First, depending on lifestyle, the groups exhibited significant differences in demographic characteristics (age, race, religion, and education level). Second, differences in purchasing behaviors (purchasing frequency, place, and information sources of imported food products) were verified. Especially, purchasing frequency of imported food was higher in the high interest consumer group compared to the other groups. Based on these results, marketing implications of the study findings are discussed.

A total of 321 salaried employees were surveyed by questionnaires during September and October 2001 in order to investigate the bases for their choices between 26 popular menu items in JinJu restaurants. The subjects were aged 20 to 61 years, and were classified into 3 age groups (ages 20-29, 30-39, and over 40) and 2 gender groups. The data were analyzed using the SAS program for factor analysis. The results of this study were as follows: 1) The 26 popular menu items were classified into 6 factors by the 20-29 age group, into 5 factors by the 30-39 age group, and into 3 factors by the over 40 age group. The younger age group had the more numbers of factor which act as choice criteria of restaurant foods according to the purpose of eating out. 2) Because subjects classified steak and fast food into the same factor named 'new generation's food', we found that steak was an unfamiliar food for most of them, 3) The 20-29 age group had an aversion to Boshintang(dog soup), while the 30-39 age group and the over 40 age group liked Boshintang as a stamina food. 4) The over 40 age group, and men in all age groups, didn't choose Buffet and Shabushabu as a dinner food because they had negative attitudes toward novel or unfamiliar foods. 5) Women distinguished between a factor called 'social drink and party food' from a facor called 'dinner food', while men integrated the factor of 'dinner food' into the factor of 'social drink and party food' 6) Men preferred Samgyetang (chicken stew with ginseng) and Yangnyeumtongdak (spicy fried chicken) as a 'social drink and party food', while women preferred Dwaejibossam (boiled pork and kimchi) and Beef Bulgogi. In conclusion, most of subjects did not recognize fast food and steak as a meal, which were introduced recently in JinJu. The choice criteria and preferences of restaurant foods were different from the age and gender groups. The over 40 age group, and men in all age groups, had more negative attitudes toward novel or unfamiliar foods than the younger age and women groups.(Korean J. Nutrition 35(9) : 996~1006, 2002)

To find out what foods and dishes are being consumed by people with dyslipidemia, we have researched which food groups and dish groups are utilized in order to use for nutrition educations. The data was obtained from participants in 2001 KNHNS using the 24hours recall method. Ages over 30 years old are used for the analysis. Food and dish group intakes are analyzed by gender, age, residence, education, and economic status. Dyslipidemia are divided into A, B and C groups using guideline of dyslipidemia. The differences in food consumption were analyzed and assessed by GMDVF, DDS and DVS. SAS and SPSS were used for the data analysis. Overall, In food group, people in B and C (with dyslipidemia) have higher intake levels of vegetables, while people in A (without dyslipidemia) have higher intake levels of fruits (p < 0.05). In dish group, people in B and C (with dyslipidemia) have higher intake levels of rice dish, soups and kimchi, while people A (without dyslipidemia) have higher intake levels of breads and snacks, salad and fruits (p < 0.05). In the dietary patterns of main food group (GMDVF), the pattern excluding dairy (11011) revealed the highest proportion in all groups. DDS = 4 has the highest proportion in all groups. The proportions of subjects with the low dietary diversity score increased in B and C (with dyslipidemia). Food groups that most people do not consume were dairy and fruits. The level of DVS in A (without dyslipidemia) is higher than in B and C (with dyslipidemia). With these results, it is shown that people with dyslipidemia had worse quality patterns of food intake than those without dyslipidemia. Thus we should emphasize the balanced diet and educate people how to choose foods. So it is necessary to develop food guide for people with dyslipidemia.

The consumption of a wide variety of food groups is considered one of the key components of nutritional adequacy. The 2005 Dietary Guidelines for Koreans includes the consumption of a variety of foods from diverse food groups as a component of a normal diet. A survey was conducted to evaluate the relationship between the dietary diversity of food groups and nutrient intake in elderly patients (age 65 and above) at a rural area in Korea (Inje). 296 subjects (111 male and 185 female) were probed in a 3 day 24-recall dietary survey. Subjects were grouped according to food group intake frequency, based on six food groups (grain, meat/fish/legume/egg, vegetable, fat/oil, dairy, fruit). Nutritional quality was evaluated according to the numbers of nutrients under EAR (Estimated Average Requirements), and MAR (mean adequacy ratios). The frequency of elderly subjects consuming a meat/fish/legumes/egg food group less than once per day was 29.4%. The frequency of elderly subjects consuming fat/oil food group less than once per day was 65.8%. The percentage of subjects who did not eat dairy food was 88.8%, and that of subjects who did not eat fruit was 57.5%. A stepwise multiple regression analysis was used to develop models relating nutritional quality to possible food group intake frequency factors. Using the number of nutrients under EAR as a dependent variable, the meat/fish/legume/egg food group intake frequency explained 9.9% of variance, followed by the grain group, fat/oil group, dairy group, and vegetable and fruit group (Model $R^2$=0.260). For mean nutrient adequacy ratio as a dependent variable, the model $R^2$ was 0.326. The results of this study suggest that a highly varied diet in elderly might be associated with better nutritional quality, as assessed by nutrient intake. Accordingly, dietary guidelines should take into consideration nutritional characteristics in order to improve intake from all major food groups and to provide a variety of foods in the diet.
