  • The purpose of this article is twofold: 1) to provide nutrition professionals with the history of how the concept of sustainable diets was introduced to the nutrition profession and 2) to describe how different sustainable agricultural practices offer potential for improving human nutrition and health. The idea of connecting sustainable agriculture With the promotion of human nutrition and health is not new. It is a concept that was introduced to the nutrition profession more than 20 years ago. To foster healthful, sustainable diets, consumers need to choose more whole foods. From the standpoint of nutrition and health, whole foods are naturally higher in fiber and lower in fat, sodium, sugar and additives compared to highly processed foods. From the standpoint of agricultural sustainability, whole foods bypass the high-energy costs of food processing and transportation. Organic farming systems offer potential benefits to human health through reducing farmers' exposure to pesticides and by increasing the total phenolic content in selected food crops. Participation in farmers' market nutrition programs and gardening has been associated with increased fruit and vegetable intake. Gardening may also be a way to increase access to fresh produce in low-income populations that do not have access to nutritious food outlets and to increase physical activity. Further research is needed to assess the human nutrition and health benefits of other types of sustainable agriculture strategies and to investigate the links among different agricultural practices with nutrient and total phenolic content in a wider variety of important food crops.

  • To understand the molecular mechanism involved in the survivability of cold-tolerant lactic acid bacteria was of great significance in food processing, since these bacteria play a key role in a variety of low-temperature fermented foods. In this study, the cold-stress response of probiotic Lactobacillus plantarum K25 isolated from Tibetan kefir grains was analyzed by iTRAQ proteomic method. By comparing differentially expressed (DE) protein profiles of the strain incubated at 10℃ and 37℃, 506 DE proteins were identified. The DE proteins involved in carbohydrate, amino acid and fatty acid biosynthesis and metabolism were significantly down-regulated, leading to a specific energy conservation survival mode. The DE proteins related to DNA repair, transcription and translation were up-regulated, implicating change of gene expression and more protein biosynthesis needed in response to cold stress. In addition, two-component system, quorum sensing and ABC (ATP-binding cassette) transporters also participated in cell cold-adaptation process. These findings provide novel insight into the cold-resistance mechanism in L. plantarum with potential application in low temperature fermented or preserved foods.

  • The article demonstrates a method of studying human health and nutrition by applying a multi-disciplinary approach and examines how humans developed and survived by adjusting to their environment. This process involves physiological, cultural and genetic adaptation both independently and interactively. This study postulates that a sound human health may be the result of balance between nutrition and environmental conditions. It is noted that there is a positive correlation between malaria and fava bean intake, and sickle cell anemia and cassava intake. It is also suggested that the difference in disease structure in soybean and non-soybean consumption cultures can be explained by an ecological approach to studying nutrition. This study further suggest that the relationship between nutrition and socio-cultural system. epidmiological study of nutrition and cultural environment nutrition and conceptual characteristics, nutrition and food intake pattern, nutrition and health sociological functions and the physioloical, cultural and genetic adaptation can all be stimulating research subjects to be studied form and ecological point of view. This article also includes the results from a series of ecological studies conducted by the author investigating the relationship between nutritional status of Korean breast-feeding mothers and the composition of the human milk and also the Vitamin D status of Korean and their lifestyle.

  • Freshwater fish intake is a critical parameter for deriving water quality criteria and water quality standards for protection of human health based on human health risk assessment. Although the freshwater fish intake parameter should be accurate and representative of Korean fish consumption for the water quality criteria to be reliable, data are limited in Korea and have low reliability. In this study, Korean National Health and Nutrition Examination Survey data from 2008-2010 were analyzed to reevaluate freshwater fish consumption. Based on these results, an average consumption rate of 3.0 g/day per person, a $90^{th}$ percentile consumption rate of 0.0 g/day per person, an average consumption rate of 65.7 g/day per fish consumer, and a $90^{th}$ percentile consumption rate of 153.4 g/day per fish consumer were proposed for derivation of water quality criteria using a conservative approach and various exposure scenarios.

  • The exopolysaccharide (EPS) produced by Bacillus amyloliquefaciens GSBa-1 was isolated and purified by ethanol precipitation, and DEAE-cellulose and Sepharose CL-6B chromatographies. The molecular mass of the purified EPS was determined to be 54 kDa. Monosaccharide analysis showed that the EPS was composed of predominantly glucose, and it was further confirmed by NMR spectroscopy to be ${\alpha}-glucan$ that consisted of a trisaccharide repeating unit with possible presence of two ${\alpha}-(1{\rightarrow}3)$ and one ${\alpha}-(1{\rightarrow}6)$ glucosidic linkages. Microstructural analysis showed that the EPS appeared as ellipsoid or globose with a smooth surface. The EPS had a degradation temperature at $240^{\circ}C$. Furthermore, the EPS had strong DPPH and hydroxyl radical scavenging activities, and moderate superoxidant anion scavenging and metal ion-chelating activities. This is the first characterization of a glucan produced by B. amyloliquefaciens with strong antioxidant activity. The results of this study suggest the potential of the EPS from B. amyloliquefaciens GSBa-1 to serve as a natural antioxidant for application in functional products.

  • The purpose of this study was to investigate food habits, nutritional knowledge, nutritional risk factors, health-related lifestyle, health status and dietetic therapy in Korean middle-aged and elderly outpatients taking supplements. A cross-sectional survey was conducted from July to December in 2001. Subjects were 1702 (male 731, female 971) age-related chronic disease outpatients aged over 50 years. Data was collected using a standardized Questionnaire by in-person interview and analyzed by SPSS system. The subjects with supplement had significantly lower nutritional knowledge, higher nutritional risk factors, undesirable lifestyle, and lower self-reported health status compared to those without supplement. However, the subjects with supplement had desirable (cod habits and more concern about health compared to those without supplement. Age-related chronic disease group with supplement had significantly undesirable food habits, lower nutritional knowledge and higher nutritional risk factors compared to control group with supplement. Age-related chronic disease group without supplement had significantly desirable food habits, higher nutritional knowledge, lower self-reported health status and higher stress compared to control group without supplement. Therefore, these results may provide basic information for proper supplement of Korean middle-aged and elderly outpatients.

  • This paper overviews the historical background and development of applied nutrition and community nutrition in Korea. The nutrition studies in the early years focused on animal experiments, human metabolism, and food analysis and therefore were limited to classrooms and research laboratories in universities without spreading into the lives of people. Korean specialists trained through the UN International Course of Applied Nutrition initiated the Applied Nutrition Program (ANP) in Korea in the 1960s. The ANP in Korea was effectively implemented until 1986 with support from UNICEF, FAO, and WHO as a national project to improve the nutrition and health of rural residents. With economic development and urbanization in Korea, the rural-focusing ANP was re-born to a more extended version with the name of "Community Nutrition", targeting the nutrition and health of the entire Korean population. Scholarly associations including the Korean Society of Community Nutrition established in 1995 have significantly contributed to the development of Community Nutrition in Korea and are expected to continue to work for a better connection between nutrition and health promotion.

  • The purpose of this study was to investigate self-perception and practices of health and appearance, health-related lifestyles and dietary behaviors of college students(137 male, 115 female) attending web class via the Internet. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. The average height, weight and BMI of the male and female college students were 174.4cm, 67.8kg, 22.3kg/㎡ and 162.3cm, 52.1kg, 19.8kg/㎡, respectively. Male collage students perceived their health statuses significantly better compared to female students. As for self-evaluation of anemia, female college students perceived significantly more anemia symptoms compared to male college students. Female college students perceived their body image to be obese compared to male college students. Underweight college students perceived significantly less healthy statuses, more anemia symptoms, and worse hair conditions compared to other college students. The rate of male students who exercise was significantly higher compared to that of female students. Male students reported significantly more smoking and drinking of alcohol compared to female students. The rate of female college students skipping meals was significantly higher than that of male college students. Frequency of eating out in female college students was significantly higher compared to that in male students. These results may provide some basic information in developing a nutrition education program for Korean college students using Internet.
