Two experiments were carried out to study the effects of corticosterone (CORT) administration on intestinal morphology and function of broilers. In both experiments, birds were randomly divided into two equal groups. One group was the control group (CTRL), and the birds were fed with a basal diet. The other was the experimental group (CORT), and the birds were fed with the basal diet plus 30 mg of CORT/kg diet. At 21 days of age, performance, morphological characteristics of intestine, D-xylose level in plasma, activities of digestive enzymes in digesta, digestibility of nutrients and 5-bromo-2-deoxyuridine (BrdUrd)-labeling index of intestinal epithelial cells were determined. CORT administration decreased feed intake, daily gain and feed conversion ratio (p<0.05). CORT also decreased duodenal and jejunal villus height (p<0.05) as well as crypt depth (p<0.05). The D-xylose level in plasma of CORT-treated broilers was lower than that of the control (p<0.05). CORT treatment caused a decrease in apparent digestibility of protein (p<0.05), whereas fat and starch apparent digestibilities were unaffected (p>0.05). CORT administration increased activities of trypsin and amylase (p<0.05), and decreased BrdUrd-labeling index of duodenal and jejunal epithelial cells (p<0.05). In conclusion, CORT administration impaired the normal morphology and absorptive capacity of the small intestine of broiler chickens.

In recent years, manufacturers of animal-based foods with health claims have encountered difficulties in the labeling of their products because of a lack of regulation on defining the functionality of animal-based foods. Therefore, this study was conducted to establish the basic requirements for the development of a definition for functional animal-based foods by investigating consumer and industry awareness. Survey data were collected from 114 industry representatives and 1,100 consumers. The questions of the survey included items on production status and future production plans, functionality labeling, promotion plans, establishment of definition, the role of the government, consumer perception, and selection of products. The results show that both industry representatives and consumers believe that legislation and the provision of scientific evidence should be improved for the development of a functional animal-based foods market. The results obtained from this study will contribute to consumer trust by supplying correct information and can be utilized in the industry as basic data for the development of functional animal-based food products.

Nutrition label (NL) on the package of processed food provides consumers with a reliable and consistent source of information . It has been considered as a useful aid for food selection and a potent educational tool for nutrition in daily life. Since current nutrition labeling regulation in Korea does not define a format for presenting nutrition information a wide variety of NL format exists in the markers created by individual manufacturers. Development of standard NL format and its registration remain to be the work for the professionals and government officials. However the acceptance and evaluation of NL by the consumers is a very important and necessary process in the development of NL formats. In this study four different formats A, B, C, D were formulated based on currently circulating labels and new U.S.NL. Subjects used for evaluation of these formats were middle -aged highly educated housewives, who and the potential users of NL. Major parameters observed through the questionnare were their nutritional knowledge of RDA, ability of IC(Information Comparison) and CA (Comprehension and Application of informed nutrient contents), as well as their preference to the different formats. The results are summarized as follows. 1) Of the 178 subjects , 89.9% of the middleaged housewives were college graduates. Their nutrition knowledge of RDA were relatively satisfactory showing over 80% correlation on the basic concepts and unit while for numerical value less than 50% correct answer. 2) IC test scores were significantly different among the formats showing the highest values for format A and B which are presented as absolute value and % RDA, respectively. Format C presented as serving size(number of products) showed the lowest score. CA scores were also significantly different, though the increased load of information did not facilitate to increase the consumers comprehension. 3) RDA knowledge test scores and the scores of IA and CA were correlated in format A and D but not in format B and C suggesting % RDA presentation would be more acceptable to the less educated group. 4) For the preference in the aspects of easiness and time-saving format A was the best one then format D supporting the result of IC and CA test. The results of the present study indicate the most useful and preferred format is the simplest format presented as absolute value without RDA, . The secondly preferred format is the new NL format of the US with much information .

In this study, we investigated that consumers could differentiate between levels of claims and clarify how a visual aid influences consumer understanding of the different claim levels. We interviewed 2,000 consumers in 13 shopping malls on their perception of and confidence in different levels of health claims using seven point scales. The average confidence scores given by participants were 4.17 for the probable level and 4.07 for the possible level; the score for the probable level was significantly higher than that for the possible level (P < 0.05). Scores for confidence in claims after reading labels with and without a visual aid were 5.27 and 4.43, respectively; the score for labeling with a visual aid was significantly higher than for labeling without a visual aid (P < 0.01). Our results provide compelling evidence that providing health claims with qualifying language differentiating levels of scientific evidence can help consumers understand the strength of scientific evidence behind those claims. Moreover, when a visual aid was included, consumers perceived the scientific levels more clearly and had greater confidence in their meanings than when a visual aid was not included. Although this result suggests that consumers react differently to different claim levels, it is not yet clear whether consumers understand the variations in the degree of scientific support.

This study was performed to analyze children's perceptions and practice levels according to gender and obesity status using a dietary life safety index. A national survey was conducted on fifth grade children (n = 2,400), who were selected using three-stage stratified cluster sampling from 16 provinces. The average height was 144.8 cm, and weight was 38.8 kg. The average body mass index was 18.4 kg/$m^2$ and underweight, overweight, and obese children were identified using the 2009 KHNANES cutoff values, which were 5.3%, 10%, and 5.9%, respectively. The perception and practice scores for hand-washing prior to eating were high and the score for willing to buy at a clean store was also high. However, students answered that the hygiene level of food stores near the school was poor. More students skipped breakfast than lunch or dinner. The frequency scores for fruit and vegetables were significantly higher for girls than those for boys. Students had a good understanding of nutrition labeling but did not frequently check the label. Seventy-five percent of the students tried to avoid high calorie foods with low nutritional value, but only 40% had the appropriate knowledge about high calorie foods with low nutritional value. Girls had better dietary life perception and practice levels than those of boys. No differences in perception or practice levels were observed based on obesity status. Nutrition education on the importance of eating breakfast and having accurate knowledge on nutrition labeling and high calorie foods with low nutritional value is needed. Behavior-centered education should be implemented to improve the perceptions and practice level of student's dietary life.

A food allergy is described an adverse immunological reaction to a food item. It is increasingly common problem among infants, children, teenagers, and adults worldwide. This study examines food allergy knowledge, attitudes, practices, and health consciousness among college students studying food and nutrition and childhood education. A total of 235 food and nutrition and childhood education college students participated in the survey. According to the results, 41.3% of the respondents were aware of legal obligations associated labeling food items for food allergy; 14.0% were diagnosed with food allergy by their doctor; and 10.2% knew about food allergy symptoms. Food and nutrition students were more knowledgeable than childhood education students. The mean for food allergy attitudes was 4.22, and the score for food and nutrition students was higher than that for childhood education students. The mean for food allergy behaviors was 2.16, and the score of food and nutrition students was higher than that of childhood education students. The importance of food allergens was significantly higher than performance. These results suggest that, to improve the management of food allergies in foodservice operations, education programs regarding food allergies should be provided food and nutrition and childhood education students.

본 연구는 칼슘과 철 그리고 철과 아연의 상호작용과 신뢰성있는 영양정보를 제공하기 위해 영양강조표시제품 중 칼슘, 철, 아연의 함량을 분석하고 표시량과 분석값을 비교하였다. 칼슘, 철, 아연을 강조표시한 제품(시리얼, 과자, 두유, 초콜릿가공품, 기타코코아가공품, 당류가공품, 과줆채음료, 고형차) 총 42건을 수거하였으며 칼슘, 철, 아연은 무기성분의 건식분해법으로 전 처리한 후 Inductively Coupled Plasma Spectrometer (ICP)로 실험하였다. 칼슘이 강조표시된 제품 42건에 대한 표시량 비율은 87~176%이었으며, 철이 강조표시된 제품 13건에 대한 표시량 비율은 84~167%, 아연이 강조표시된 제품 6건에 대한 표시량 비율은 98~275%였다. 모든 분석값이 표시량 대비 80% 이상으로 식품 등의 표시기준을 충족하였다. 칼슘과 철의 상호작용은 한국인의 칼슘 섭취가 1일 권장량의 68.7% 수준으로 부족하므로 칼슘의 과다섭취로 인한 철의 흡수방해는 우려할 만한 상황은 아닌 것으로 보인다. 또한, 분석한 영양강조표시제품의 철과 아연의 함량 비율이 1.53:1이 최대였으므로 철의 과다섭취로 인한 아연의 흡수방해는 우려할 만한 상황은 아니었다. 그러나 업체에서는 칼슘, 철, 아연을 강조한제품을 생산할 시에 영양소의 상호작용을 고려하여 생산을 해야 할 것이고 소비자에게 정확한 영양정보를 제공하고 적정량의 영양섭취를 위해서는 지속적인 모니터링을 통해 식품표시에 대한 주기적인 관리가 필요할 것으로 생각된다.

According to Article 7 and Annex B of the World Trade Organization(WTO) Agreement on the Application of Sanitary and Phytosanitary(SPS) Measures, WTO members are required to notify their newly established or amended SPS measures that might affect international trade. This study analyzed SPS notifications from 1995 to 2008 to identify international trends for food safety measures. The notifications were collected from the SPS information management system and the official document distribution system of WTO. The 153 WTO members represented 37 developed countries, 84 developing countries and 32 least developed countries. The number of overall notifications was 9,820. The annual notifications increased from 198 in 1995 to 1,264 in 2008. The monthly average notifications were from 44.8 in December to 69.5 in June; however, there were no statistical differences among them. The six leading Members in terms of notification submissions were United States(U.S.), Brazil, New Zealand, Canada, European Community and Korea. Among the regular and emergency notifications, 62.7% notifications were concerned with food safety, followed by animal and plant protections. Among animal protection notifications, 54.8% were emergency situations. Of the 4,821 food safety notifications, 60.4% were from developed countries, and 39.3% were from developing countries. Measures concerning pesticide residues and risk assessments were mainly from developed countries. In contrast, 77.5% of the measures concerning zoonoses were from developing countries. However considering the numbers of developing and developed countries, the average number of measures for each country was similar. Food safety measures were mainly involved pesticide residues followed by food additives, zoonoses, new regulations, labeling. As the overall notifications, zoonosis measures were mainly emergency notifications. Measures concerning pesticide residues, food additives, zoonoses, new regulations, veterinary drugs, and labeling were submitted most often by the U.S., Korea, Albania, U.S., Australia, and U.S., respectively. Identifying the exact trends of food safety measures was complicated by a number of factors. However, WTO notifications might be useful tool in providing a general view of international trends.
