This study examined the status of current nutrition labelling and claims for the processed foods that were purchased in the supermarket. They were assessed in the aspects of frequency and content of nutrition labelling and claims. The results are summarized as follows; The percentage of products contain the nutrition labelling or claims of processed foods of investigation were 18.7% and 18.8% respectively. In the nutrition labelling method, the format separated by expression contents with 'only liability indication nutrient'or 'liability indication nutrients plus discretion indication nutrients' were 44.7% and 43.4% respectively. In the case of type and title, 'table' and 'nutrition composition'were used most frequently, 83.9% and 83.2% respectively. And in the case of expression unit, 'per 100 g or 100 ml'was higher (56.8%) than others. Nutrition claims were divided into 'nutrition content claim'and 'comparative claim', in the former the most claim was 'containing'and in the other'more or plus'used most frequently.'Nutrient function claim'was 13.4% and 'Implied nutrient claim'was 7.3% of all the claims. Results of the evaluation of current nutrition labeling system, nutrition labelling was less advanced and variable in content and format and also the information was not easy for consumers to understand and use them. To support achievement of the nutrition label, there must be program and initiatives for better understanding and communication and guidances on food labelling and nutrition for food manufactures.

The purpose of this study was to investigate consumer preferred formats of nutrition labels: the type of nutritional information provided on the labels. A survey was conducted on 222 housewives between the age of 20 and 65 in Daejeon city in 1998, using an interview questionnaire showing illustrated nutritional label formats. Among twelve nutrients and caloric values listed on the nutrition labels, the housewives ranked their interest in the items in the following order of calorie (58.56%), calcium (56.76%), cholesterol (54.05%), protein (39.19%) and vitamin C (36.04%). The majority of the subjects (69.37%) checked labels when they bought milk or dairy products, whereas only 8.11% looked at labels when they bought Ramyon or noodles. Most of the subjects (90.99%) preferred products with labels with nutritional information as compared with products without labels. this was especially so true of the younger individuals and of pc-ople who checked food labels more frequently. The subjects preferred labeling which described the nutrient content per Package (55.41%), sewing size (32.88%) and food weight of 1009 (11.71%) as a standard nit. Generally, they prefer-red a simplified list to a detailed list of the number of nutrients, a figure graph to bar graph in nutrition claim, vertical bar graph to horizontal bar graph showing the nutritional content of foods and a web-type graphic format to a radiation-format when describing the item's percentage of the Korean RDA's nutrient content. The subjects who checked labels frequently especially preferred detailed list, while housewives with job or with unhealthy family members preferred a simplified list and graphic, rather than a numerical display. From this result, it is suggested that providing consumers with more nutrients information in a more easily understood graphic format would encourage the consumers to check nutritional labels. Therefore this should be considered when developing the regulations far nutrition labeling or when educating the Public about nutrition. (Korean J Community Nutrition 8(2) : 220∼230, 2003)

The objective of this study was to investigate the current status of calcium fortification in processed foods for obtaining basic data on nutrition fortification policy and nutrition labeling, Surveyed samples were the products fortified wish calcium among processed products sold in department store and large mart in Seoul from Aug. 1998 to Aug. 1999. But supplementary health food or special nutritious food and weaning food and infant formula were excluded from them. We examined the kinds and numbers of added nutrients except calcium and the amounts of calcium per 100 g product and nutrient labeling of calcium-fortified foods. Surveyed products were 81 foods and they were grouped in grain products, milk and milk products, processed meat and fishes, ramyuns, retort pouch foods, fruit juice and drinks. and others. Calcium fortification was found in wide food groups, especially in snack foods and carbonated beverages. In relation to surveyed products, most of them were fortified with only calcium. The number of added nutrients in the product were relatively various in comparison with each food groups. In addition to calcium, the most frequently added nutrient was DHA, and were followed vitamin, mineral, oligosacchride, fiber, etc. This result showed that the kind(s) and the number(s) of nutrient added to product did not consider nutrition balance of calcium-fortified foods. Units of calcium content were decided by companies, therefore consumers confused labelled content with mouth dose of calcium and the comparison of the amounts added calcium among products was difficult. The amounts of calcium in products were from 16.4 to 1226 mg Per 100 and from 2.5 to 27.6% RDA (recommended daily allowance) per serving size. The amounts of calcium in many products were less than 10% RDA per serving size, whole appraisal about fortified content was needed. And for nutrient labeling on calcium, they used various term whether it is approved by law or not.

This study was conducted to devise a scheme for the development of foods designated as Yookmee (“6 dishes), which are representative food of Daejeon area. The Yookmee consist of Seolleongtang(ox bone soup and boiled rice), Samgyetang (chicken stew stuffed with glutinous rice and ginseng), Dolsotbap (boiled rice mixed with vegetables), Goojeukmook (acorn jelly), Sootgol-naengmyeon (cold buckwheat noodles with broth) and Daecheongho minmulgogi-maeuntang (spicy hot freshwater fish soup). A questionnaire was developed and administered by means of an interview regarding the subjects' recognition of and preference for the six dishes, their usual eating places and eating frequencies, the need for some standardization of recipes and for nutrition labeling including serving sizes and nutrient content. The total number of subjects who participated in this study were 328 (male 112, female 216) living in Daejeon. The subjects who were aware of the presence of Yookmee were more in their thirties or older (15%) compared to those in their twenties (9.6%) The percentages of the subjects who recognized the Yookmee as the representative foods were twice among those in their thirties (over 60%), as compared to 31.5% in their twenties (p<0.001). Samgyetang was one of the favorite foods of all the Yookmee among those in their twenties and Goojeukmook was the favorite for all the other age groups. The incidence of those eating one of Yookmee more than once a month was 51.5% in all the age groups, but the intake frequency was lower among those in their twenties (43.8%). The percentage of those who recommended Yookmee as a food for guests was the highest among those in their fifties (54.7%). The first reason why the subjects do not recommend these foods was because they were unfamiliar with Yookmee; among those in their thirties and forties the 2nd reason was because it is not much enough in quality or quantity to be served as a food for guests. Over 60% of the subjects felt the need for standardization of Yookmee, recipes for especially those in their fifties did feel the needs (92.5%). Furthemore, regarding labeling of sowing sizes and nutrients contents, over 80% of the subjects wanted these, and this desire tended to increase with age. From these results, it seems reasonable to accept Yookmee as the representative foods of Daejeon, despite the fact that many people do not yet currently do so. Since most of the subjects (85.4%) partake Yookmee outside of their homes, it is recommended that efforts need to be expanded on enhancing the nutritional quality, the taste and the quality control of Yookmee by standardizing the recipes, labeling the serving sizes and nutrient contents, and providing educational and publicity programs.

The purpose of this study was to compare convenience food purchasing behaviors and food habits. The study, which asked surveyed 131 female college students in Daejeon, in 2011, on how they used nutrition labels. The subjects were divided into two groups, in terms of the way they checked examined nutrition labels: a "Check" group(n=62, 47.3%) and a "No check" group(n=69, 52.7%). Reasons given for not reading nutrition labelings were "a habit of buying" for 72.2%, and "too small or rude" for 19.1%. The "Check" group reported higher interest in nutrition(p<0.001) and hygiene(p<0.01) than the "No check" group. Those who used the labels had higher cereal(p<0.01) and vegetable(p<0.01) consumption and a lower intake of fast foods(p<0.05). But however, most of the subjects(65.6%) chose by taste, at the time they purchased the convenience foods. The subjects considered "expiry date"(n=87, 66.4%) to be more important information on food labels than "nutrient composition"(n=11, 8.4%). The number of products whose nutrition labels were checked by over 50% was five out of 12. In conclusion, our study suggests that proper use of nutrition labeling may improve food choices and enable healthy dietary practices. Further efforts are needed to provide the public with nutrition education programs on how to read nutrition labeling. Modifying nutrition labels to make them easier for the public to understand should also be considered.

Objectives: Vitamin C has various functions such as antioxidative effect and supporting absorption of iron (Fe). Aim of this present study was to provide vitamin C nutrition information and to briefly evaluate absorption interaction of vitamin C and Fe content of vitamin C emphasized products. Methods: Vitamin C emphasized foods including beverages, cereal, snacks, chocolate products, other cocoa products, and sugary products were examined by HPLC. Fe contents in samples after dry-ashing were examined by ICP. Results: Vitamin C content ranges in various products tested were the following: beverages (n=11) $20.15{\pm}0.08{\sim}845.41{\pm}6.07mg$, cereal (n=11) $52.50{\pm}0.23{\sim}262.50{\pm}0.07mg$, snacks (n=1) $50.00{\pm}0.25mg$, chocolate products (n=1) $311.73{\pm}2.44mg$, other cocoa products (n=1) $311.73{\pm}2.44mg$, other sugary products (n=2) $52.50{\pm}0.23{\sim}262.50{\pm}0.07mg$. Vitamin C (n=27) analysis values ranged from 82 to 450% of the labeled value. Vitamin C content in vitamin C emphasized food (n=6) was estimated 7.7 times~56.6 times more than Fe content. Conclusions: Analyzed samples ranged more than 80% of the labeled value in vitamin C emphasized products, which complied with food labeling regulation. But, beverages (n=3), cereal (n=4), chocolate products (n=1) were 2 times more than the labeled value. To provide accurate nutrition information, food manufactures should supervise nutrition labeling and understand the interactions between nutrients. Also, consumer should decide about the adequate amount of nutrient intake by thoroughly checking nutrition labeling.

The purposes of this study were to establish the scope of population groups to be set and nutrients to be included for Codex Nutrient Reference Values (NRVs). Examination of a variety of documents and reports on the principles of scientific evidence was gone through to choose representative groups from a variety of population groups and kinds of nutrients for setting Codex NRVs. Also, hearings from the groups of NRVs expertise has been formed and was gone through by e-working process. The differences of food and foods being consumed in general and by specific population groups and limited actual space on packages for food labeling were considered. This paper suggest the options on the scope of population groups to be set and nutrients to be included for Codex NRVs on the basis of the above procedures. Also, the advantages and disadvantages of these options are commented when the options are applied for establishment and revision of the Codex NRVs.

This study determined the effects of television (TV) advertising restriction of Energy-Dense and Nutrient-Poor Foods on product and promotion activities by food companies producing or selling children's favorite foods. A survey using a selfadministered questionnaire was conducted via on-line or fax by marketers or R&D managers from 108 food companies. The data from 55 respondents (50.9%) were analyzed. Restriction exerted positive effects on food products with respect to compliance with labeling requirements (4.0 out of 5 points) and reinforcement of nutritional contents examination of new products (3.7 out of 5 points). Reformulations of products such as reduction of nutrients like sodium, sugar and fat were also reported. In addition, food companies underwent diverse changes in promotional activities, including modification of package designs and displays in stores, offering free gifts, discounts, etc. In conclusion, restriction of TV food advertising may contribute to improvement of children's food environment by encouraging food companies to make favorable product changes. On the other hand, the results also revealed that food companies adopt diverse marketing channels that are not yet under regulation. Hence, to make policies more effective, regulation needs to be extended from TV to other marketing channels to which children are easily exposed.

The development and differentiation of endothelial cells (ECs) are fundamental processes with significant implications for both health and disease. ECs, which are found in all organs and blood vessels, play a crucial role in facilitating nutrient and waste exchange and maintaining proper vessel function. Understanding the intricate signaling pathways involved in EC development holds great promise for enhancing vascularization, tissue engineering, and vascular regeneration. Hematopoietic stem cells originating from hemogenic ECs, give rise to diverse immune cell populations, and the interaction between ECs and immune cells is vital for maintaining vascular integrity and regulating immune responses. Dysregulation of vascular development pathways can lead to various diseases, including cancer, where tumor-specific ECs promote tumor growth through angiogenesis. Recent advancements in single-cell genomics and in vivo genetic labeling have shed light on EC development, plasticity, and heterogeneity, uncovering tissue-specific gene expression and crucial signaling pathways. This review explores the potential of ECs in various applications, presenting novel opportunities for advancing vascular medicine and treatment strategies.

Purpose: This study was conducted in order to investigate nutrient and food intake status and dietary quality in Korean adults according to nutrition label utilization. Methods: We analyzed data from the combined 2010-2011 KNHANES (Korean National Health and Nutrition Examination Survey). The analysis included 8190 adults aged 19 to 64 years. In this study, according to nutrition label utilization, we classified the subjects according to the "non-utilization of nutrition label (NUNL)" group (male, n = 2716, female, n = 3147), "identification of nutrition label (INL)" group (male, n = 143, female, n = 330), and "Utilization of nutrition label (UNL)" group (male, n = 363, female, n = 1491). Nutrient and food group intake, NAR (nutrient adequacy ratio), MAR (mean adequacy ratio), and INQ (index of nutritional quality) were analyzed using data from the 24-recall method. Results: Results of this study showed that subjects in the NUNL group were significantly more likely to drink alcohol compared with the other two groups. The NUNL group showed a significantly higher frequency of consuming instant noodles, Soju (male), and carbonated drink (female) than the UNL group, whereas the NUNL group showed a significantly lower frequency of consuming milk, soymilk, and yogurt than the UNL group. In addition, regarding diet quality (NAR and INQ), significantly lower vitamin $B_2$, vitamin C, and calcium was observed in the NUNL group compared with the UNL group. For both male and female, significantly higher MAR was observed in the UNL group than in the NUNL group. The NUNL group showed significantly lower consumption of milk compared to the UNL group. Conclusion: Good dietary practice such as referring to nutrition labels and its influence can affect the quality of nutritional intake and selection of food, while it can also provide basic data for specific nutrition education regarding use of nutrition labeling.
