The personalized meal service is being developed to prevent and alleviate illnesses according to the individual's health condition. However, the current meal does not provide a fully customized service to individuals and a diet that meets the consumer's information needs. The cause is the lack of information on the ingredients and the difficulty of comparative analysis between the materials. Therefore, in this study, we propose basic analysis process for basic information acquisition and database construction for food composition before providing personalized food. In this study, we investigated the content of carbohydrate, reducing sugar and protein as basic components of Grifola frondosa and investigate the content of polyphenol as a biological active ingredients. Respectively. Studies on the hypoglycemic effect of the diabetic rat model have been carried out in relation to the prevention of diseases. Based on the results of this study, it is also possible to obtain information on the basic ingredients of the food and to analyze the information on the content and activity of the biological active ingredients. Using animal models, information on disease prevention and mitigation was also available. The process introduced in this study is applied to various food materials, accumulating data, and utilizing Database, this results will be an excellent tool for providing more efficient service by providing a proper dietary composition for consumers.

Purpose: This study evaluated the effects of personalized nutrition intervention for increasing hospital meal intake by elderly patients with malnutrition. Methods: The subjects were 30 elderly patients with malnutrition who visited a general hospital located in Daegu. An individual nutrition intervention such as change of meal types or special meal service was given to the patients according to nutrition diagnosis related to inadequate intake of hospital meals. Nutritional intake status of the subjects was assessed by analyzing energy intake, protein intake, index of nutritional quality (INQ), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR). Results: The causes of inadequate intake in the subjects were poor appetite or preference problems (46.7%), symptom-related problems (30.0%) and mastication problems (23.3%). The INQ of protein in the subjects was significantly increased from $0.81{\pm}0.17$ to $1.41{\pm}0.25$ after the nutrition intervention (p < 0.05). The NAR of protein (before $0.50{\pm}0.21$, after $0.58{\pm}0.17$), iron (before $0.72{\pm}0.30$, after $0.84{\pm}0.29$) and vitamin $B_2$ (before $0.31{\pm}0.16$, after $0.37{\pm}0.14$) was also increased after the nutrition intervention (p < 0.05). The MAR of five nutrients, protein, calcium, iron, vitamin A and vitamin $B_2$, was significantly increased by the nutrition intervention (p < 0.05). Conclusion: Personalized nutrition intervention according to nutrition diagnosis related to inadequate intake of hospital meals may improve the intake amount of elderly patients with malnutrition.

A food exchange system for diabetes is a useful tool for meal planning and nutritional education. The first edition of the Korean food exchange lists was developed in 1988 and the second edition was revised in 1995. With recent changes in the food marketplace and eating patterns of Koreans, the third edition of food exchange lists was revised in 2010 by the Korean Diabetes Association, the Korean Nutrition Society, the Korean Society of Community Nutrition, the Korean Dietetic Association and the Korean Association of Diabetes Dietetic Educators through a joint research effort. The third edition is based on nutritional recommendations for people with diabetes and focuses on adding foods to implement personalized nutrition therapy considering individual preferences in diverse dietary environment. Foods were selected based on scientific evidence including the 2007 Korea National Health and Nutrition Examination Survey data analysis and survey responses from 53 diabetes dietetic educators. While a few foods were deleted, a number of foods were added, with 313 food items in food group lists and 339 food items in the appendix. Consistent with previous editions, the third edition of the food exchange lists included six food categories (grains, meat, vegetables, fats and oils, milk, and fruits). The milk group was subdivided into whole milk group and low fat milk. The standard nutrient content in one exchange from each food group was almost the same as the previous edition. Korea Food & Drug Administration's FANTASY (Food And Nutrient daTA SYstem) database was used to obtain nutrient values for each individual food and to determine the serving size most appropriate for matching reference nutrients values by each food group. The revised food exchange lists were subjected to a public hearing by experts. The third edition of the food exchange lists will be a helpful tool for educating people with diabetes to select the kinds and amounts of foods for glycemic control, which will eventually lead to preventing complications while maintaining the pleasure of eating.
