Construction of web-based nutrition education contents and searching engine for usage of healthy menu of children

A diet habit, which is developed in childhood, lasts for a life time. In this sense, nutrition education and early exposure to healthy menus in childhood is important. Children these days have easy access to the internet. Thus, a web-based nutrition education program for children is an effective tool for nutrition education of children. This site provides the material of the nutrition education for children with characters which are personified nutrients. The 151 menus are stored in the site together with video script of the cooking process. The menus are classified by the criteria based on age, menu type and the ethnic origin of the menu. The site provides a search function. There are three kinds of search conditions which are key words, menu type and "between" expression of nutrients such as calorie and other nutrients. The site is developed with the operating system Windows 2003 Server, the web server ZEUS 5, development language JSP, and database management system Oracle 10 g.

Prevalence of Nutrition Labeling and Claims on Processed, and Packaged Foods / 대한지역사회영양학회지

This study investigated the prevalence of nutrition labeling and claims on processed and packaged foods. The final database consists of 1,287 foods, which were collected in two supermarkets in the Seoul area from September to November, 2006. An estimated 78% of KFDA-regulated processed, and packaged foods have nutrition labels. Nutrient content claims on food labels were identified in 21% of the foods which have nutrition labels. The prevalence of nutrition labels in this study is much higher than in previous studies due to the current expansion of the mandatory labeling regulation. However, false labeling and misleading contents claims were also identified. The food label is an important tool for enhancing the public's understanding of healthy choices of processed foods. Therefore, to maximize the benefits of the nutrition labeling regulation, industries, government agencies and health professionals should work together to help consumers make healthy dietary choices and improve their health.

Changes in Antioxident Nutrients and Vitamin B1 Contents of Gamma Irradiated Foods Consumed most Frequently in Korea

Food irradiation has been steadily increased in many countries concomitantly with increasing international trades and concerns about naturally occurring harmful contaminants of food. Although, irradiation provides an excellent safeguard for the consumer by destroying harmful bacteria, it would be necessary to investigate nutritional adequacy of irradiated foods with a special emphasis on such foods as red pepper powders, cold-water fishes (mackerel), sesame seeds that are widely consumed in Korea. These food items are of special concern due to the fact that most of them are imported and that several nutrients contained in them are sensitively reacting to irradiation. We observed changes in the antioxidant nutrients contents, such as vitamin A, beta-carotene, vitamin C and total phenol, and also vitamin B1 in the foods that were irradiated at different dose levels. The nutrients contents in red pepper were respectively 98.6% and 92.3% for total phenol, and 97.8% and 94.5% for beta-carotene, right after irradiation at the dose of 10 and 20 kGy. The vitamin C contents decreased with irradiation doses up to 76.4% (10 kGy) and 68.5% (20 kGy) and B1 contents decreased to 54.9% and 80.7% of non irradiated red pepper. When the mackerel was irradiated at the applied dose of 3 and 7 kGy, total phenol concentration of the irradiated fish was respectively 91.3% and 94.2% of non irradiated fish. The amounts of vitamin A were 82.6% (3 kGy) and 78.0% (7 kGy) of unirradiated sample and vitamin B1 contents reduced to 30.5% and 51.5%. alpha-Tocopherol content was 33.9% of the non-irradiated one when it was irradiated at 7 kGy. Vitamin A and gamma-tocopherol contents in sesame seeds linearly decreased with the applied doses (5 and 10 kGy). Vitamin A contents decreased up to 87.8% (5 kGy) and 82.9% (10 kGy) and that of gamma-tocopherol were 72.4% and 66.5% of the unirradiated sample.
