This study examined the sweet taste perception, perception of sugar reduction, and utilization of nutrition labeling according to the awareness of the self-perceived sugar intake reduction of university students in Chungbuk Area. The subjects (n=419) were divided into two groups: Awareness of Sugar Intake Reduction (ASIR) group, male=110, female=109; Non Awareness of Sugar Intake Reduction (NASIR) group, male=115, female=85. The overweight/obesity was significantly higher in the ASIR group than in the NASIR group for both male and female students. The sweet taste perception was significantly lower in the ASIR group in male students than in the NASIR group. The purchase level of a product with reduced sugar instead of the original products was significantly higher in the ASIR group in male students than the NASIR group. Beverage purchases after identifying the sugar content were significantly higher in the ASIR group in male students than in the NASIR group. The necessity of nutrition labeling education was significantly higher in the ASIR group both male and female students. Based on these results, the correct perception of sugar reduction and continuous and practical nutrition education of sugar intake reduction need to maintain healthy dietary habits in university students.

Nutrition labeling can provide information in order for people to select products suitable for their own health, and sodium content labeling for processed foods is important since sodium is one of the main causes of cardiac diseases. This study had carried out to propose the desirable sodium content labeling by conducting surveys on the awareness of sodium content in processed foods, understanding of sodium content labeling, and requirements for new sodium comparative claims. The survey period was from 12th of September, 2016 through the 24th, during which a self-administered questionnaire survey was given to 1,003 persons through demographic quota sampling by age and region. As a result of the survey, 66.0% of respondents assuring nutrition labeling answered they check sodium content labeling, whereas 83.2% were aware of excessive intake of sodium having a negative effect on health. Exactly 49.9% of respondents answered that the current system for nutrition labeling on processed foods does not help one to understand the content of sodium, whereas 72.9% answered they wanted to compare sodium contents with those of other products when buying or taking processed foods. As 92.5% cited the importance of sodium comparative claims made by processed foods, preparation of a new system for food labeling should be considered by which consumers can easily compare sodium contents with those of other similar products.

MR system은 Discovery 750W(General electronics. USA), 32channel head coil을 사용하였다. single delay ASL은 512 sampling points on 8 spirals, TR:4466ms, TE:10ms, NEX:2, post label delay:1525ms 의 권고 parameter, 7delays eASL은 640 sampling points on 4 spirals, TR:5868ms, TE:10ms, NEX:1의 권고 parameter 를 제외한 나머지 parameter 인 slice thickness: 6mm, number of slice:26, labeling plane: acquisition volume하방 20mm 로 동일하게 하고, post labeling delay를 각각 1회, exponential spacing 7 delays(label duration 1000ms~3500ms)로 하여 spirals 3D fast spin echo imaging sequence로 데이터를 획득, rCBFmap과 corrected rCBFmap을 비교하였다. 영상평가는 정량적 평가와 정성적 평가로 나누어 실시하였다. 정량적 평가는 각각의 rCBFmap에서 상대적 정상 flow가 유입된다고 판단되는 cerebellum의 CBF-value를 100%기준으로 하여 lesion이 확실한 단면, 또는 중간 번째 단면의 rCBFmap에 frontal lobe 4, parietal lobe 2, occipital lobe 2, 총 8구역에 동일한 크기의 ROI를 통해 측정한 CBF-value와의 대비(%)로 수치화 하여 평가하였고, 정성적 평가는 영상의학과 두경부 신경계 판독의 1명과 MRI실에 근무경력 3년 이상인 방사선사 2명 을 대상으로 리커트(Likert scale) 5점 척도로 평가하였다. 정량적, 정성적 평가 모두 SPSS 23.0(SPSS INC. Chicago. IL. USA)을 이용하여 p<0.05일 때 통계적으로 유의한 것으로 판단하였다. 측정, 평가자간 신뢰도는 반복 측정치를 이용한 급 내 상관계수인 ICC(intraclass correlation coefficient)를 구하여 0.75(p<0.05) 이상 나올 경우 신뢰성이 높은 것으로 간주하였다. 결 과 : 정량적 평가에서는 각 측정 부위에 대한 백분위 상대치의 평균값에서 측정 region A에서만 7delays eASL기법이 0.61낮은 수치를 보였을 뿐 B~H에 이르는 전 구간에서 각각 4.32, 7.69, 18.33, 11.46, 26.26, 16.47, 19.9만큼의 상대치 평균 차이가 높은 값을 보였고 모든 측정부위의 p-value는 p<0.05로 통계적으로 유의한 차이를 보였다. 측정자간 신뢰도는 0.805~0.869(p<0.05)로 나타났다. 정성적 평가에서는 리커트 5점 척도 결과 single delay ASL, 7delays eASL 각 각 혈 류신호 균일성에서 2.75±0.94, 4.19±0.78 , 백질 회백질 구분에서 3.64±0.57, 4.08±0.81, 지연혈류 표현에서 2.25± 0.95, 4.16±0.83, 관류대조도 표현에서 3.75±0.50, 4.75±0.50의 결과를 보였다. 비교결과 7delays eASL의 평균 점수가 모두 높았으나 백질 회백질 구분 항목에서 p>0.05(p=0.130)으로 통계적 유의한 차이는 보이지 않았고 나머지 항목에서는 p<0.05(p=0.006, 0.007, 0.004)로 통계적으로 유의한 차이를 보였다. 평가자간 신뢰도는 0.774~0.854(p<0.05)로 통계적 으로 높은 신뢰도를 나타냈다. 결 론 : 7 delays eASL을 이용하여 획득한 뇌관류(brain perfusion)영상은 single delay ASL의 영상과 비교했을 때 진단적으로 유효하다고 판단할 수 있다. 비교적 긴 시간 동안 혈류의 정보를 획득함으로 검사과정에서 발생 가능한 기술적 오류를 줄이고, 상대적으로 놓칠 수 있는 지연혈류의 확인이 가능한 7delays eASL 기법은 내인성(endogenous) 관류 획득 방법으로, 진단적으로 보다 개선된 뇌 관류영상을 얻는데 유용한 방법이라 판단된다.

The purpose of this study was to investigate perception of the Food Allergy Labeling System (FALS) of school foodservice in female middle school students. The subjects were 148 female middle school students in the Incheon metropolitan area. In this cross-sectional study, data were collected using self-administered questionnaires. Only 20.9% of subjects had experience of food allergy education. There was no significant difference in food allergy knowledge by grade. The scores of perception of food allergy labeling by school foodservice were significantly higher in lower grade students (p<0.001). In all grades, highest scores were observed for ‘food allergy labeling is necessary’, whereas the lowest scores were for ‘I check the food allergy labeling’. The percentages of subjects who wanted to participate in food allergy education were significantly different (p<0.01); 73.8% in 1st grade, 50.0% in 2nd grade, and 35.7% in 3rd grade. For desired education contents to enhance perception of FALS, 57.5% of subjects answered ‘emergency management’ and 23.0% said ‘information of food allergy causing food’. Therefore, it is necessary to increase food allergy education and educate female middle school students according to grade in order to enhance perception of FALS.

본 연구에서는 1차 농수산물 및 축산물의 기능성 표시광고를 제한하는 법 제도적 제한요인을 탐색하 였다. 우선 이를 위해 선행연구들을 참조하여 농수산물의 품질 및 안전성과 직결되거나 식품표시와 관 련된 법령인 양곡관리법, 축산물위생관리법, 식품위생법, 건강기능식품에 관한 법률, 시행령, 시행규칙 및 표시광고 관련 조항들을 고찰하였다. 법 조항의 적용 시 법률간 관리대상 식품 형태 및 범위의 모호 성, 규제대상 영업자 모호한 설정이 농수산물 기능성 표시광고의 주요 제한요인으로 판단된다. 또한 법 령 주관부처 별 중복규제 가능성, 행정처분 기준의 모호성 등이 확인되었다. 본 연구를 통해 농식품의 기능성 표시광고 제한요인을 도출하였으며, 이는 1차 농수산물 경쟁력 강화를 위한 정책 기초자료로 활 용될 수 있다.

한국 정부는 그동안 음식점 원산지 제도를 지속적으로 발전시켜왔는데, 2015년 기준 16개 품목에 대 한 원산지 표시지가 시행 중에 있다. 그럼에도 소비자 측면에서의 음식점 원산지 표지제도에 대한 분석 이 부족하여, 연구의 필요성이 제기되고 있다. 본 연구에서는 소비자 설문조사와 계량분석(순위 프로빗 모형)을 통해 음식점 원산지 표시제도에 대한 소비자 인식을 분석하였다. 그 결과, 소비자들은 현지 시 행중인 원산지 표시제에 긍정적인 인식을 가지고 있었고, 향후 대상 품목 확대를 요구하고 있었는데 농 산물에 대한 표시제도 확대에 대한 요구가 더 많았다. 소비자들은 원산지 표시제도 위반자에 대한 처벌 강화도 요구하고 있어 향후 검토가 필요한 것으로 생각된다. 이상의 결과를 바탕으로 한국의 음식점 원 산지 표시제도는 성공적인 성과를 내고 있는 것으로 나타났고, 앞으로 더욱 제도를 강화할 당위성이 제 기되었다.

This study was to investigate the association among satisfaction of nutrition labeling, change of purchase behaviors, and dietary life care, based on the awareness of nutrition labeling at expressway rest areas. The subjects (n=903) were divided into two groups, according to the awareness of nutrition labeling: Awareness of Nutrition Labeling (ANL) group, n=367; Non Awareness of Nutrition Labeling (NANL) group, n=536. Effort of health care and identification of nutrition labeling was significantly higher in the ANL group, compared with the NANL group. As for the main reason for not identifying nutrition labeling, ‘not interested in nutrition labeling’ was the highest in the ANL group, and ‘Don't know nutrition labeling is provided’ in the NANL group. Identification ratio of nutrition labeling in future was significantly higher in the NANL group, compared with the ANL group among the subjects who didn't identify nutrition labeling before. After their becoming aware, a change of food purchase after reading the nutrition labeling was significantly higher in the ANL group, compared with the NANL group. Health beliefs on the nutrition labeling were significantly higher in the ANL group, compared with the NANL group. Satisfaction of nutrition labeling was also significantly higher in the ANL group, compared with the NANL group. The ANL group also expressed a necessity of expansion of nutrition labeling, compared with the NANL group. In the ANL group, identification of nutrition labeling was significantly higher in the hard effort group, compared with the little effort group of dietary life care. Therefore, improvement and campaign of nutrition labeling for consumers at expressway rest areas, especially for the NANL group, will be effective in identifying nutrition labeling for their health care.

The study was carried out to investigate the efficacy of current nutrition labeling of processed foods and examine awareness among university students of nutrition information given current nutrition labels, and also awareness of the one-serving size of snacks that come in differently sized packages. A total of 100 students in Chungbuk, Korea participated in this study. About 60% of the subjects knew about nutrition labeling; however, a very small percentage (11%) of the subjects reported an experience of being educated about nutrition labeling. Also, just 32% of the students checked nutrition labels when they purchased processed foods. When understanding of nutrition information on labels of snacks in differently sized packaging was tested, over 80% of the subjects understood nutrition information accurately. Five different package sizes were studied. Of these 5, packages containing about 200% of one standard serving showed the highest rate of misunderstanding of total energy contents per container. Interestingly, the students most strongly preferred containers that contained 300% of one standard serving. From these results, we conclude that students consider the current recommendation for a serving size to be small, which may be related to misreading of nutrition labels of snacks that come in packages containing less than 300% of one standard serving size. To improve accurate understanding of nutrition labels of snacks, total package labels or dual column labels on packages containing less than 300% of one standard serving size should be considered.

The purpose of this study is to investigate 5th grade elementary school girls’ effort to recognize and use nutritional labels on processed foods and restaurant meals to encourage dietary behavior. The subjects (n=976) were divided into three groups (effort group, n=711; normal group, n=193; and no-effort group, n=72) depending on level of effort for the healthy dietary behavior such as eating balanced meals, eating three meals regularly, and eating meals slowly. In the effort group, the frequency of food intake for breads, ramen, noodles and fast foods was significantly lower, while frequency of food intake for fruits and vegetables and salad was significantly higher than in the other two groups. In the effort group, the ratio of the respondents that perception of nutrition labeling on processed foods and restaurant meals was 80.5% and 31.4% and the ratio of girls who checked the nutrition labeling at their point of purchase was 71.1% and 24.7%, respectively. Reasons given for not reading nutrition labeling for restaurant meals were ‘not interested’ for 34.6% of the effort group, and 52.2% of the no-effort group. Therefore, it is necessary to create an educational program on healthy dietary behavior, including how to read nutrition labeling and establishment of proper body image perception for elementary school girls.

Restaurants implement menu labeling to provide nutritional information to customers in an attempt to help customers select healthy menu items. Considering the increase in food-away-from-home consumption, the purpose of this study was to identify motivators and barriers in restaurant customers regarding use of menu labeling. Data were collected from a survey on restaurant customers in Seoul, Korea. The findings of this study indicate that customers used menu labeling for health reasons. However, barriers to using menu labeling were identified as small font size, difficulty in locating nutritional information display, and difficulty in interpreting nutritional information. In addition, they also suggested expanding the scope of menu labeling for restaurants by including chain restaurants with less than 100 units. The findings of this study offer strategies for the government to improve menu labeling practices for customers.

The purpose of this study is to evaluate the changes in perception concerning nutrition labeling and students' availability of processed foods and is to investigate parents' awareness of nutrition labeling through the 'Education program on safety management of children's dietary life' conducting directly to the fifth grade elementary school students (4,105 persons) by the nutrition teacher in each school. The part that checked when purchasing processed food before and after the students' education, the name of manufacturer (p<0.05), raw material and content (p<0.001), food additives (p<0.001), nutritive components (p<0.05) etc. were significantly improved. An idea about nutrition labeling has increased after the education, the question items in 'it is reliable' (p<0.001), 'satisfied' (p<0.01) were significantly increased particularly. In spite of one time education, it showed positive changes such as it can be possible to get desired nutrition information. Thus, although it was one time training conducted in the situation that can not be carried out formal education due to school environment, a variety of practical education of children's dietary life is required targeting comprehensive senior students, the education is considered to be conducted for children as well as parents.

In this paper, we study the effectiveness of social labeling as a technique to promote pro-environmental behaviors in children, and examine more specifically the potential moderating effect of children’s age. We run an experiment on a sample of 115 3rd to 6th grade children and show that 1/ children exposed to a social labeling actually declare more pro-environmental behaviors and that 2/ children at an intermediate age (between 9 years and a half and 11 years and a half) are the most responsive to the technique, underlying an inverted-U relationship between social labeling effectiveness and children's age. These results contribute to a better theoretical understanding of social labeling mechanisms and suggest implications for public policy makers.

We studied customer recognition and understanding of menu labeling as well as the correlations between customer support for menu labeling and multiple factors, such as demographic characteristics, dinning-out behavior, and menu selection criteria. This study designed a survey and received responses from 351 individuals. The analysis results reveal that most respondents did not acknowledge menu labeling or lacked knowledge of it. Many of the respondents showed experience in ordering from menus with ingredient labels, but many showed no interest in menu labeling. Exactly 114 (32.5%) respondents showed support of menu labeling, and most were interested in levels of trans-fat, fat, and cholesterol. The respondents reported that menu labeling should be implemented more in fast-food restaurants and causal dinning restaurants. This study also analyzed how customer menu selection criteria are related to support level of menu labeling. Respondents were classified into three groups based on their support level for menu labeling (low · medium · high), after which correlations between customer menu selection criteria and support level were examined. Respondents in the high support group considered all menu selection criteria (i.e., ingredients, health, and consideration of calories). GLM analysis showed that monthly dining-out expenses were highly related to support level with a significance level of 0.05, and the interaction between monthly dining-out expenses and respondents' jobs also affected support level with a significance level of 0.01.

최근 사회경제적 환경의 변화는 개인의 식품 소비에도 많 은 영향을 주었으며, 외식의 비중 또한 크게 증가하였다. 외 식의 증가로 건강에 미치는 영향력이 커짐에 따라 올바른 음 식선택을 위한 영양성분이나 건강정보를 알려주는 영양표시 의 중요성이 강조되고 있다. 그러나 아직은 외식업체 영양표 시가 의무사항은 아니며 외식 시 소비자들의 영양표시 활용 에 대한 인식 또한 부족한 것이 사실이다. 특히 한식 메뉴에 대한 영양표시 연구는 거의 없는 실정으로 영양표시를 통한 영양관리의 중요성을 강조하고, 한식당 영양표시제도 마련을 위한 기초자료를 제공하고자 하였다. 본 연구는 일부 경기지 역에 거주하는 20세 이상의 성인을 대상으로 2010년 2월 5일 부터 2월 27일까지 한식당 영양표시에 대한 설문조사를 실시 하였고, SPSS 18.0 package program을 이용하여 일반적 특성, 영양표시에 대한 인식, 일반적 특성에 따른 영양표시 내용과 영양성분별 중요성 차이 등을 분석하였다. 본 연구의 결과를 요약하면 다음과 같다. 1. 조사 대상자는 전체 268명으로 여자(60.4%)가 남자(39.6%) 보다 많았으며, 연령은 50대 이상(40.3%)이 가장 많았다. 학 력은 고졸(47.8%)과 대졸(42.2%)이 전체의 90.0%로 대부분을 차지하였으며, 외식횟수는 한 달에 3~4회가 54.5%로 가장 많 았다. 2. 한식당 메뉴 영양표시 요구도는 3.99점으로 높았으며, 메뉴 선택 시 영양표시 활용의지(3.89) 또한 높았다. 영양표 시 내용으로는 건강이나 영양관련 정보제공이 4.06점으로 가 장 높았으며, 식재료와 영양소의 설명 3.93점, 1인 분량의 표 시 3.77점이었다. 3. 영양표시를 원하는 영양소로는 나트륨이 4.16점으로 가 장 높았으며, 그 다음으로는 콜레스테롤(4.15), 열량(4.04), 지 방(3.93), 칼슘(3.84), 단백질(3.83), 당질(3.71)의 순이었다. 4. 일반적 특성에 따른 한식당 영양표시 요구도와 활용의 지 차이 분석 결과, 영양표시 요구도는 여성(4.05)이 남성(3.91) 보다 높아 유의적인 차이(p<0.01)가 있었으며, 20대가 4.29점 으로 가장 높았으며, 학력은 대졸(4.15)이 높아 유의적인 차 이가 있었다(p<0.01). 영양표시 활용의지는 여성(3.97)이 남성 (3.77)보다 높았으며(p<0.01), 영양표시에 대한 요구도가 높은 경우에 활용의지 또한 높은 것으로 나타났다. 5. 일반적 특성에 따른 영양표시 내용으로는 1인 분량에 대한 중요성은 여성(3.89)이 남성(3.58)보다 높아 차이가 있었 으며(p<0.01), 중졸(3.13), 고졸(3.70), 대졸(3.90), 대학원졸(4.08) 순으로 학력이 높을수록 차이(p<0.01)를 보였다. 식재료와 영 양소에 대한 설명은 여성이 4.02점으로 남성 3.77점에 비해 유의적 차이가 있었으며(p<0.01), 학력이 높을수록 식재료와 영양소를 중요하게 생각하고 있음을 알 수 있었다(p<0.05). 건강이나 영양정보 제공은 50대 이상이 4.18점으로 높아 유 의적인 차이가 있었다(p<0.05). 6. 한식 메뉴의 영양표시가 식생활에 미치는 영향은 남성 (3.73)보다는 여성(4.01)이 컸으며(p<0.001), 학력이 높을수록 영향이 큰 것으로 나타났다(p<0.01). 본 연구결과, 한식당에서의 영양표시에 대한 소비자들의 요구도가 높고, 건강한 외식을 위한 메뉴 선택 시 활용의지 또한 높은 것으로 나타나, 영양표시가 건강한 식생활 영위를 위한 중요한 교육도구가 될 수 있을 것으로 보인다. 특히 여 성들이 영양표시에 대한 관심이 높은 것을 알 수 있었으며, 일반적 특성에 따라 영양표시 내용이나 영양소에 대한 차이 가 있는 것으로 나타나, 외식업체에서는 운영 메뉴와 주고객 층에 맞는 차별화된 영양표시 방안의 마련이 경쟁력 확보에 도움이 될 것으로 사료된다.

This study investigated the knowledge, attitude, and behavior of 280 University students towards nutrition labels. The purpose of the study was to examine knowledge, attitudes, and behaviors of university students regarding nutrition labeling, and whether body mass index (BMI) with nutrition labeling was associated with knowledge, attitudes, and behaviors. Descriptive statistics analyzed knowledge, attitudes, and behaviors of university students regarding food labeling. The ANOVA and χ2 analysis was evaluated and assessed for its relationship with BMI. Pearson's correlation coefficient analysis examined relationships between knowledge, attitudes, and behaviors. More than 90 percent of answers relating to 11 nutritional knowledge questions were correct. Only 30% of participants answered correctly regarding questions about plan source oil and cholesterol content. Attitudes and behaviors of nutrition labels were significantly higher among participants who were obese (p<0.001). Knowledge score was positively correlated with general label usage behavior (r=.169, p<0.01), and item buying behavior (r=0.142, p<0.05). Attitude also was positively correlated with behavior (p<0.01). Nutrition labeling education efforts are needed to provide university students with a nutritional education program and information on how to read nutritional labels and apply this information to their lives. University students need to understand their need for numerous nutrients instead of merely focusing on the fat and calories of foods.

The purpose of this study was to develop measures for establishing and enforcing legal nutrition labeling for Takju based on results from consumer awareness surveys, statistical model development, and evaluation of nutrients. The statistical model developed with consumer survey results showed that consumers would like to know the nutrients they intake from drinking Takju, as their awareness about Takju was low. Specifically, consumers would like to see information regarding alcohol content, calories, carbohydrates, and saccharides on the label. Structural equations from the research model showed that consumers who had some knowledge of Takju also had positive thoughts of the nutrition fact labels for Takju. Evaluation of nutrients in Takju showed that the starch sources and other ingredients used in Takju fermentation did not influence nutrient facts, and nutrient concentrations also varied among the different Takju. In addition, this research suggests methods for consumers to make reasonable selections and to inform them of the nutrition fact labeling for Takju. Benners and pop-up were manufactured to promote voluntary participation of companies and to provide nutrition facts from Takju. Eventually, a measure was suggested to establish and enforce nutrition labeling, using results from consumer and nutrient surveys of Takju.

To promote use of nutrition labels, degrees of awareness, use, and satisfaction of nutrition labeling on eating-out menus were investigated by a self-recorded questionnaire from May to July 2010 in 629 participants who visited four bakery chains (n=409) and three ice-cream chains (n=220) located in Daejeon. Of the subjects 53.4% were female, 68.8% aged 20~29 years, and 59.3% visited bakery or ice-cream stores 1~3 times per month. Only 38.2% of participants had knowledge of nutrition-labeling mandates for eating-out menus, and 74.9% had seen labels before in bakery and ice-cream stores. Most subjects understood calorie amount and daily value of sodium very well, but they failed to understand the meaning of daily value. Only 21.2% of the subjects understood nutrition label information completely. Of the participants, 46.7% read nutrition labels in bakery or ice-cream stores when purchasing. Among the subjects who read the labels, 77.2% (36.1% of total subjects) referred to the label information when selecting a menu and 46.9% (21.9% of total subjects) had experienced altering their menu choice based on the information. Exactly 53.3% of subjects answered they did not read nutrition labels since they were not interested or had no time, or because the labels were not noticeable. Satisfaction of the place, timing, and format of nutrition labels at bakery and ice-cream stores fell below average overall. Many subjects wanted trans fat and cholesterol to be added to the labels. In conclusion, degrees of perception, use, and satisfaction of nutrition labels at bakery and ice-cream stores were still low. More effective publicity and consumer education about nutrition labeling will be necessary, and bakery or ice-cream companies should make efforts to improve nutrition labeling such as providing format and place.

본 연구는 2000년 이래 영국과 미국의 주요 지도제작사 및 지리교재 제작사가 제작한 지도를 중심으로 동해 해역의 지명표기 형태를 조사하고, 그 원칙을 분석한 것이다. 대부분의 지도 제작사들은 지명표기와 관련하여 자체의 원칙을 가지고 있는데, 동해 해역은 ‘일본해(동해)’의 형태로 병기했지만, 여전히 ‘일본해’로 단독 표기한 경우도 있다. 한편 지리교재 제작사는 지명표기를 저자들의 판단에 맡기고 있다. 그 결과 지리교재에 따라 동해 해역에 대한 지명표기가 다양하게 나타났다. 국제사회에서 동해 지명의 확산을 위해, 영미권의 주요 지도제작사 및 지리교재의 저자들에게 동해 지명의 정당성을 전략적으로 홍보할 필요성이 있다.

This study examined the understanding and use of information on nutrition labels based on one serving size among female consumers above the age of 20 in Seoul area. According to the survey, 69.9% of respondents were aware of the current system of nutrition labeling based on one serving size, and 51.8% of the respondents expressed their dissatisfaction with the system because the nutrition labels were difficult to understand or appeared unreliable. The nutrition label literacy of the consumers varied with respect to different packaging units. The respondents were likely to be less accurate in calculating the expected caloric intake when only portions of a multi-serving package were used. Initially 69.0% of respondents reported that they had read the nutrition label before purchasing a product but 91.9% of respondents said that they would check the label after learning how to read the label properly. It is very important to make consumers aware that the labels are very reliable sources of nutrition information. A public education campaign on the use of nutrition labels should focus on developing the consumers' ability and skills in using the label information when choosing foods.

Nanotechnology is currently receiving considerable attention in various fields of biotechnology. The uptake of nanoparticles by cells for labeling and tracking is a critical process for many biomedical therapeutic applications. However, nanoparticle labeling of porcine hematopoietic cells has not been demonstrated so far. In the present study, silica-coated nanoparticles conjugated with rhodamine B isothiocyanate (SR-RITC) were used to investigate the uptake of nanoparticles by porcine hematopoietic cells. Flow cytometric and confocal microscopic analyses reveled that the cells were efficiently internalized by the silica-coated nanoparticles. Furthermore, biocompatibility tests demonstrated that the SR nanoparticles were not cytotoxic, and they had no impact on proliferation. Our study demonstrates that silica-coated nanoparticles are taken up very rapidly and with high efficiency into porcine hematopoietic cells, with no apparent deleterious effects. Therefore, silica-coated nanoparticles appear to be a promising tool for tracking porcine hematopoietic cells.
