El sistema de porciones de intercambio es una metodología sencilla y rápida que se utiliza para entregar indicaciones alimentarias a usuarios sanos y con patologías. Se realizó una revisión bibliográfica para actualizar conceptos y evaluar la vigencia de su uso y sus aplicaciones. El sistema es ampliamente usado en diferentes países, incluyendo Chile, existiendo distintos tipos de listas de alimentos y preparaciones según la metodología de la definición de las porciones, o bien según diversidad y número de alimentos presentes. Su uso es mayormente con fines asistenciales, siendo también útil en educación comunitaria y docencia. En Chile, los listados de porciones intercambiables fueron publicados el año 1999 y no se han actualizado hasta la fecha. Razones como el cambio en el perfil epidemiológico, mayor acceso a la información y la diversificación de alimentos en la dieta, hace necesario una revisión in extenso de los listados nacionales, con el fin de incorporar mayor diversidad de alimentos y preparaciones típicas a tan masiva y necesaria herramienta técnica, que es fundamental para el profesional Nutricionista y un aporte a la salud y a la cultura de los países.

A review was carried out to update concepts and evaluate the current state of the exchange list used and their application. The system is widely used in different countries, including Chile, there are different types of foods or preparations exchange lists that use different methodologies for the definition of portions, according to the diversity and number of foods present. Its use is mainly for healthcare purposes, being also useful in community education and college teaching. In Chile, the food portion exchange lists were published in 1999 and have not been updated since. Reasons such as the change in the epidemiological profile, greater access to information and the diversification of foods in the diet, make necessary an in-depth review of the national lists, in order to incorporate a greater diversity of foods and typical preparations. Exchange lists are a necessary technical tool fundamental for nutrition professionals and contribute to the health and culture of countries.

A Survey of Diabetic Educators and Patients for the Revision of Korean Food Exchange Lists

BACKGROUND: Food exchange lists are one of the main methods of nutritional education. However, Korean food exchange lists have not been revised since 1994. Therefore, we surveyed the opinions of diabetes educators and patients with diabetes regarding the need for revision of the current food exchange lists. METHODS: For two weeks beginning on 10 March 2008, a 12-item questionnaire regarding the opinion and need for revision of the current food exchange lists was e-mailed to diabetes educators nationwide. Another 15-question survey was administered to patients with diabetes in 13 hospitals located in the Seoul and Gyeonggi regions of Korea. RESULTS: We obtained survey responses from 101 diabetes educators and 209 patients; 65 (64.3%) of the educators answered that the current food exchange lists should be revised. The items that needed revision were the glycemic index, addition of new foods and reaffirmation of exchange standard amounts. The patients demanded specific education about choosing appropriate foods, a balanced meal plan, proper snacks, and dining intake. CONCLUSION: Our survey results demonstrate the need to revise the Korean food exchange lists. This process should focus on glycemic index, the addition of new foods and reconfirmation of one exchange reference unit.

Korean Food Exchange Lists for Diabetes: Revised 2010

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.

The Study of Awareness and Practice of Korean Dietitians in Food Exchange Lists, Serving Size and Dietary Guidelines

Dietitians in various fields have used food exchange lists for food preparations. However ie seems that the present food exchange lists are complicated, thus they cause many problems for dietitians to use in the fields. Therefore this study evaluated to the extent of awareness and utilizations of KDA food exchange lists in dietitians and also collected dietitian's opinions for revising food exchange lists such as serving size, serving calories, and for unifying food guidelines and dietary and dietary guidelines for Korean to one simple guideline. 192 dietitians who presently work in urban and rural areas were recruited and data based on survey were collected. As results, most of dietitians(87.5%) knew well about food exchange lists, but only 7.8% of them always would use food exchange lists for menu planing, 56.3% of dietitians did not use it at all and 34.4% occasionally use it. And 88.0% of dietitians wanted to revise food exchange lists totally or partially, 69.8% of dietitians hoped to amend various calories per one serving in food exchange lists to one serving calorie. The desirable on serving calorie was selected as 100kcal(51%) or 50kcal(38%) by dietitians. The dietitians in this study understood very well dietary guidelines(86.5%) and food guidelines(88.5%) for Korean, and 66.1% dietitians wanted to unify both guidelines. In case of unification of guidelines, dietitians answered that 7~8 items(30%) or 5~6 items(27%) should be included in guideline. In the question about reference value for daily allowance, most dietitians(56%) satisfied with the present various reference values for various generation while 28% of dietitians wanted to change to have one reference value (standard with 2000kcal, adult female). This study will provide basic informations for revising or adjustment of food exchange list and dietary or food guidelines for Korean.
