The purpose of this study was to investigate the effects of a nutrition education and personalized lunch service program in a senior welfare center. A total of 30 elderly (14 males, 16 females) aged 62~89 years participated in this study. Nutrition education lessons (2 hour/lesson/week) were provided for 4 weeks. Also, ten weeks from week 3rd to week 12th, personalized lunch providing 1/3 personal needed energy was served 5 times for a week. After the nutrition intervention program, we compared anthropometric characteristics, blood biochemical characteristics, nutrition knowledge, dietary attitude and dietary intake using 24 hr recall with those before the intervention. The body weight (p < 0.001) and body mass index (BMI) (p < 0.001) were decreased. There were significant increases in score of nutrition knowledge (p < 0.01) and consumption of milk & milk products for snacks. There was a positive effect on fasting blood sugar (FBS) showing significant decreases in portion of impaired fasting glucose and diabetes mellitus (p < 0.05). Also, serum triglyceride (TG) was significantly decreased (p < 0.05). In evaluation of nutrient intake by Dietary Reference Intakes for Koreans (KDRIs), riboflavin (p < 0.01), vitamin C (p < 0.001), calcium (p < 0.05) were positively improved. The index of nutritional quality (INQ) and intakes of vitamin C (p < 0.001), riboflavin (p < 0.05), Ca (p < 0.01) and Fe (p < 0.05) were increased. In conclusion, this nutrition education and lunch service program providing 1/3 personal needed energy can be used to develop and implement a tailored nutritional intervention programs in the setting of a community senior welfare center to improve health and nutritional status of Korean elderly.

The purpose of the study was to implement and evaluate a nutrition capacity training program for dietitians and other professionals working at customized home visiting health services (CHVHS). This program focused on nutrition services for hypertension or diabetes mellitus patients including topics regarding CHVHS, and composed of 10 sessions with lectures, discussion and practice. Dietitians (n = 54) and other professionals (n = 20) participated in the program and completed the questionnaire to assess their understanding of nutritional management, nutrition services and CHVHS before and after the program, and to examine program satisfaction and education needs. Subjects were mostly women (98.6%) and college or university graduates (93.2%). Total score (p < 0.001), as well as all items (p < 0.001 or p < 0.01) of understanding regarding nutritional management, nutrition services and CHVHS, were significantly increased after the program both in dietitians and in other professionals. Subjects were generally satisfied with the program, showing more satisfaction with items regarding subject's participation, acquiring new knowledge, usefulness of the program for CHVHS, and education materials. In future nutrition capacity training programs, subjects wanted to have classes regarding nutrition services for specific chronic diseases, development of education materials, methods for dietary life education, modifying eating habits and so on. Other professionals compared to dietitians, showed higher education needs in meal management (p < 0.01) and nutrition counseling skills (p < 0.05). This study showed the effectiveness of a nutrition capacity training program for home-visiting dietitians and other professionals, and suggests the need and direction for future nutrition capacity training programs.

A wide ranges of chemicals released into the environment have potential to interfere with physiological and development process by disrupting endocrine pathways. Endocrine system embraces a multitude of mechanisms of action, including effect on growth, behavior, reproduction and immune function. These environmental endocrine disruptors are present in environment and pose potential health consequences to human and wildlife. The best known form in endocrine distruptors involves substances which mimic or block the action of natural hormone in the body. Endocrine disruptor have been variously defined as exogenous agents that interfere with the synthesis, secretion, transport, metabolism, binding action or elimination of the natural hormones in the body which are responsible for the maintenance of homeostasis, reproduction developmental and/or behavior. Many compounds polluted into the environment by human activity are capable of disrupting the endocrine system of animals, including fish, wildlife, and humans. Among these chemicals are pesticides, industrial chemicals, and other anthropogenic products. It has been alleged that several adverse effects on human health are linked with exposure to chemicals which are claimed to be endocrine disrupters, that is, increased incidence of testicular, prostate and female breast cancer, time dependent reductions in sperm quality and quantity, increased incidence of cryptorchidism (undescended testicles) and hypospadias(malformation of the penis), altered physical and mental de velopment in children. This observation is currently the only example of chemically mediated endocrine disruption which has resulted in a clear effect at the population level.

BACKGROUND/OBJECTIVES: This study aimed to assess the dietary behaviors of preschool children using the nutrition quotient for preschoolers (NQ-P) and analyzed the difference in the scores of the children's dietary behaviors in regards to the parents' health consciousness. SUBJECTS/METHODS: The subjects were 257 children aged 3-5 years and their parents residing in Seoul and Gyeonggi-do, South Korea. The questionnaire is composed of demographic characteristics, the NQ-P questions, and health consciousness. All data were statistically analyzed by SPSS program (ver. 25.0) and the statistical differences in variables were evaluated by χ2 test, Fisher's exact test, t-test, 1-way analysis of variance and Tukey's multiple comparison test. RESULTS: There was a significant difference on the intake frequency of processed meat by region and fast foods by age, region, and weight status (P < 0.05). There was also a significant difference in not moving around while eating by weight status and parents' effort to have healthy eating habits by sex (P < 0.05). The mean score of NQ-P of the total subjects was 59.47, which was within the medium-low grade. The mean score of balance was 61.62, and the boys were significantly higher than girls (P < 0.05). As the age of children increased, the mean score of the moderation was significantly decreased (P < 0.05). The scores of NQ-P (P < 0.05), balance (P < 0.01), and environment (P < 0.05) were significantly higher in the high group of parents' health consciousness than the low group. CONCLUSIONS: According to the results of the evaluation by NQ-P, the dietary behaviors of preschoolers residing in Seoul and Gyeonggi-do need to be improved. For improving their eating behavior and nutritional health status, parents and children need customized nutrition education programs based on sex, age, region and weight status of preschool children as well as the degree of parents' health consciousness.

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.

Rapid integration of information technology into health care systems has included the use of highly portable systems-in particular, personal digital assistants (PDAs). With their large built-in memories, fast processors, wireless connectivity, multimedia capacity, and large library of applications, PDAs have been widely adopted by physicians and nurses for patient tracking, disease management, medical references and drug information, enhancing quality of health care. Many health-related PDA applications are available to both dietetics professionals and clients. Dietetics professionals can effectively use PDAs for client tracking and support, accessing to hospital database or information, and providing better self-monitoring tools to clients. Internship programs for dietetics professionals should include training in the use of PDAs and their dietetics applications, so that new practitioners can stay abreast of this rapidly evolving technology. Several considerations to keep in mind in selecting a PDA and its applications are discussed.

This study was conducted to investigate the purchase patterns of processed foods and perception of school dietitians on nutrition labelling in Chonbuk area of Korea. Self-administered questionnaires were collected from a total 156 dietitians. Statistical data analysis was completed using the SPSS v. 11.5 program. The results were summarized as follows. Among the 156 school foodservice systems, 64.7% of schools were operated in conventional system and 35.3% were in commissary system. Among the processed foods, seasoning foods(98.4%) and cereal products(93.3%) were used widely in school foodservice. Among the general characteristics of schools and dietitians, the style(p<0.01), and type of foodservice(p<0.05), career, and age of dietitians respectively affected the purchasing pattern of the processed foods. Approximately 30% of dietitians responded that some fortified foods used for the meal preparation(eg. Ca-fortified yoghurt). Only 57% of dietitians who has more ten year job career was agreed with the important of fortified foods for the menu planning. Despite the levels of education of the dietitians became higher, were no relationship between the confidence on fortified foods and the improvement on health for children. About 96.2% of dietitians knew nutrition labelling of processed foods. Only 25.6% of dietitians checked nutrition labelling of processed food when they purchased these foods for school lunch. The main reason for their checking nutrition labelling of processed foods was for nutrient of products. The dietitians understanding and trust in nutrition labelling of processed foods were not high. But the half of dietitians responded that the nutrition labelling can be helpful for the purchase of processed foods in school foodservice systems. Therefore, it is necessary to activate the mandatory nutrition labelling of processed foods and to prepare its consumer education program for school dietitians.

The underlying physiology of algal antioxidant compounds is reviewed in the context of seaweed biology and utilization. The application of seaweed antioxidants in foods, food supplements, nutraceuticals and medicine is considered from the perspective of benefits to human health. We advocate that direct consumption of seaweed products for their antioxidant composition alone provides a useful alternative to non-natural substances, while simultaneously providing worthwhile nutritional benefits. Economic utilization of seaweeds for their antioxidant properties remains in its infancy. This review provides examples ranging from laboratory studies through to clinical trials where antioxidants derived from seaweeds may provide major health benefits that warrant subsequent investigative studies and possible utilization.

Luteolin is a plant flavonoid which exhibits anti-oxidative, anti-inflammatory and anti-tumor effects. However, the antiproliferative potential of luteolin is not fully understood. In this study, we investigated the effect of luteolin on cell cycling and apoptosis in human esophageal squamous carcinoma cell line Eca109 cells. MTT assays showed that luteolin had obvious cytotoxicity on Eca109 with an $IC_{50}$ of $70.7{\pm}1.72{\mu}M$ at 24h. Luteolin arrested cell cycle progression in the G0/G1 phase and prevented entry into S phase in a dose- and time-dependent manner. as assessed by FCM. Luteolin induced apoptosis of Eca109 cells was demonstrated by AO/EB staining assay and annexin V-FITC/PI staining. Moreover, luteolin downregulated the expression of cyclin D1, survivin and c-myc, and it also upregulated the expression of p53, in line with the fact that luteolin was able to inhibit Eca109 cell proliferation.
