  • Background: Traditionally, East-Asians (Korea, Japan, and China) utilize seaweeds as a food source and ingredient in traditional medicine. Korea is one of the biggest seaweed producer and consumer in the global trade. Especially, side dishes made from seaweeds are very popular in the traditional Korean cuisines. Seaweeds are popular as fresh vegetable salads and soup or eaten as snacks. Main body: Seaweeds are rich in essential nutrients, minerals, and vitamins as well as a promising source of novel bioactive compounds. The compounds (polysaccharides, polyphenols, and sterols) present in the edible Korean seaweeds possess important bioactive properties such as antioxidant, anti-inflammation, anticancer, anti-diabetic, and anticoagulant properties. Thus, the long-term consumption of seaweed has a potential to reduce the risk of cancer, diabetes, obesity, and inflammation-related complications. However, seaweed consumption is limited to the small population around the globe. Thus, it is important to increase the awareness of the health benefits of seaweeds consumption among the general population. Short conclusion: In the present study, we discussed some popular green and red edible Korean seaweeds and their health-promoting properties. This study might be useful to increase the public awareness of the consumption of seaweed as a food source.

  • The purpose of this study was to investigate the consumption patterns of traditional Korean rice cake among college students. Self administered questionnaires were collected from 512 college students in the Seoul, Kyunggi, Chungchung, Kyungsang, Junla and Gangwondo areas. The data were statistically analysed using frequency analysis, chi-squared and t-tests and a one-way ANOVA. By examining the results of the student's perceptions of traditional Korean rice cake, it was found that most know little, or only a moderate amount, about this type of food. Meanwhile, more than half the students liked traditional Korean rice cake, as this type of food satisfied their need for a traditional Korean taste, while the reason for disliking was that they were more familiar with western-style confectionary. Most students answered that they only ate traditional Korean rice cake on special occasions, such as big holidays or ceremonies for the dead ancestors. Most answered that they bought those foods at conventional markets, the mile in the neighborhood, (Eds note: I dont't understand, do you mean, “within a mile of their neighborhood”\ulcorner) or atbig malls. The factor they considered the most important at the time of purchase was the quality (taste), which demonstrates the need for the development of traditional Korean rice cakes, with new tastes and shapes, which still satisfy the Korean's taste, whilemaintaining the traditional taste. For the questions that asked about the problems faced by the traditional Korean rice cake manufacturing industry, and the reasons for low consumption, the students responded that buying this type of food was difficult as the outlets selling themwere not easy to find. Our results seem to suggest that there are almost no specialty stores for the sale of traditional Korean rice cake compared to the other types of cakes that are scattered all over the country. (Eds note: this is only my opinion, and I maybe wrong, but I would have thought that trying to market traditional Korean rice cakes at local convenience stores, rather than speciality stores, would make them more available to the general public. Their marketing at speciality stores will maintain the status quo, i.e. people will go to the speciality stores to purchase product for holidays and special occasions, whereas they will go to the local convenience stores to buy general everyday snacks etc.)

  • We surveyed 553 middle school students living in Incheon using questionnaires to compare their food behaviors and snack intake patterns according to weight groups based on BMI. Mean BMI was 20.3 for males and 19.6 for females. The rate of underweight, normalweight and overweight students was 33.3, 51.7, and 15.0%, respectively. Compared to the other two groups, the overweight students perceived their body shape more accurately (p<0.01). Regarding the reasons for skipping dinner, the most frequent answer by the underweight students was 'because of snacks', while that of the overweight students was 'to lose weight' (p<0.01). The normalweight students were found to eat a Korean traditional type breakfast more frequently than the other weight groups (p<0.05). The overweight female group was more likely to overeathabitually, whereas the normalweight and underweight groups tended to overeat when they were under stress (p<0.05). As for the amount of the snack intake, the overweight male students replied that they eat quite a lot of snacks. As a conclusion, the problems found in the underweight group were unbalanced diet and the disturbance of regular meal patterns due to inappropriate snack intake. The problems shown in the overweight group were overeating due to habit or stress, fast eating speed and large amount of snack intake.

  • This study investigated the food habits of the elementary school children according to obesity index. The subjects included 1,307 elementary school children classified into four groups according to their individual obesity indices: underweight, normal weight, overweight, and obesity. The distribution of subjects by BMI was 51.5% underweight, 32.9% normal weight, 7.3% overweight, and 8.3% obese. Of these children, 62.6% ate breakfast everyday, and common weight control methods were exercise and diet. Lack of appetite was the most common reason for skipping breakfast(75.3%). Most students(74.7%) had Korean traditional cooked rice and side dishes for breakfast, and 69.6% of students responded that their meal speed was $10{\sim}30$ minutes. In conclusion, the food habits influencing obesity were eating speed, snack intake after dinner, and the number of snacks, while the size of meals did not influence obesity.

  • This research involved a survey on the dietary patterns of children and adolescents living in group homes, to find out their wrong eating habits and to devise measures for correcting their problems. The BMIs of the subject children and adolescents in group homes were measured, and the result showed that although many of them appeared to have normal weights, about 42.2% were actually underweight. Most of them had meals regularly, three times a day at fixed times. However, half of them frequently skipped breakfast because of the lack of time in the morning. In addition, more than half of them had the habit of having imbalanced diets, especially with low vegetable intake. The score for their satisfaction toward meals at group homes were highest (3.97) with the taste of food, while it was relatively lower (3.61) with the variety of food than with the other items. The average score for their snack intake was 3.47, showing that the majority of them had the habit of eating snacks, while the largest portion (26.0%) of them preferred bread and cookies. According to the result of the analysis on their food intake, overall calorie intake was about 82~96% of estimated energy requirements, while that of the male subjects aged 12 or older was about 82% of the standard energy requirements. Their overall intake of calcium and potassium was lower than recommended nutrition intake, but sodium intake was higher than 3 times recommended intake. Especially, in addition to calcium and potassium, the male subjects aged 15 or older showed low intake of dietary fiber, iron, zinc, riboflavin, niacin, vitamin C and folate also; whereas the female subjects aged 15 or older showed low intake of iron, zinc, riboflavin and folate also. Taken together, it was concluded that government level of dietary life-related support and management would be necessary for the healthy growth and development of children and adolescents in group homes.

  • BACKGROUND/OBJECTIVES: The purpose of this study was to examine whether plasma lipid profiles are affected differently by snack kinds with equal calorific values. SUBJECTS/METHODS: We compared a Korean traditional confectionery (dasik) with Western confectionery (cookie) in this regard. Controlled cross-over study consisted of two 3-week snack intake phases and for separating, a 2-week washout period (3-2-3) was carried out with 30 healthy women aged between 40-59 years old. Brown rice based Korean traditional confectionery and wheat flour based Western confectionery were used. The participants consumed either dasik or cookie every day for 3 weeks, providing 93 kcal a day. RESULTS: The total cholesterol (TC) in the dasik group had decreased significantly after 3 weeks (P < 0.05). Furthermore, in the dasik group, reduction in TC and low-density lipoprotein-cholesterol were greater than those in the cookie group (P < 0.05). CONCLUSIONS: Prioritizing functional snacks like dasik improves plasma lipid profiles; this may be useful information for individuals who cannot refrain from snacking.

  • Yukwa is a popular Korean traditional fried rice snack. The high fat content and porous structure of Yukwa cause it to rapidly become rancid, presenting difficult challenges for commercial distribution. In this study, an-tioxidant activities of green tea extracts (GTE) were evaluated in Yukwa fried in soybean oil (SBO), rice bran oil (RBO) and winterized rice bran oil (WRBO) during storage at 4$0^{\circ}C$ for 12 weeks. Lipid oxidation of Yukwa was determined by acid value (AV), peroxide value (POV), p-anisidine value(AnV), totox value and sensory evaluation. The addition of GTE to the oils reduced the increases in AV, POV, AnV, and totox. Totox increased most vapidly in Yukwa fried in SBO, fellowed by RBO>WRBO>SBO+200 ppm GTE>RBO+200 ppm GTE > WRBO + 200 ppm GTE (p<0.05). Sensory evaluation revealed that the addition of 200 ppm GTE delays rancidity in Yukwa by 7~8 weeks; providing compelling evidence that GTE is an effective antioxidant for Yukwa.

  • Kitchen has been an essential space and plays an important role in the house regardless of culture and regional differences. However, due to social and economical changes, kitchen is no longer used only for preparing food and dining which seem to be a traditional function. The purpose of this study is to investigate the additional functions of the kitchen and figure out the related variables. The survey method was used to collect data from 321 housewives living in the apartment sized over 99$\textrm{m}^2$(30 pyung) in Ulsan. The data were analyzed by SPSS/$PC^+$ with frequency, percent, and chi-squared test. The results of this study were: (1) Kitchen was now used for eating snacks(45.6%), keeping household account(42.5%), and chatting(41.6%). (2) Homemakers wanted to do laundry such as ironing, drying clothes, and folding clothes in the kitchen. However, there were several activities(i.e., grooming, rest and taking a nap, exercise) they do not want to do in the kitchen. (3) The variables which related to the additional functions of the kitchen were size of the apartment, age, and level of education. The findings of this study imply that there must be design considerations for chatting and keeping household account such as providing tables and comfortable chairs. In addition, new counter layout types should be developed based on needs of additional functions and related variables.

  • Kimbugak is one of Korea's traditional snacks made of laver. This study was conducted to investigate the physical drying and frying characteristics of kimbugaks made by a pasting & garnishing machine. The drying and frying characteristics should be analyzed to develop a continuous operation system for manufacturing kimbugak because kimbugak has a high moisture content after pasting process. Materials for pasting and garnishing on laver were rice gruel and sesame. The aluminum shelf with square hole was selected as a drying shelf. The recommended size of the square hole type was $1.5mm{\times}1.5mm$ because characteristics of deformation and easy separation from the shelf were excellent at the hole size. The drying time of 2 hours was also recommended with the drying temperature of $70^{\circ}C$ based on the test results such as dried condition (good), moisture conten t (3.7%), deformation (12.1 mm), and shrinkage rate (19.8%). As the frying conditions for dried kimbugaks, recommended oil temperature and frying time were $170^{\circ}C$, 15 seconds, respectively when corn oil was used. In the case of frying for undried kimbugaks, recommended oil temperature and frying time were $210^{\circ}C$, 2 - 3 minutes, respectively for improvement of work efficiency.
