          Abstract

          Abstract The aim of this study was to determine the acceptability of low glycaemic index (GI) preparations, equivalent to the traditional high GI ones in Chile, elaborated with minimal changes in the ingredients and culinary techniques that significantly diminish the GI and maintain acceptability level. Twelve high-GI traditional lunches and their low GI counterparts were prepared. For 12 days, 20 apparently healthy women randomly tasted 2 paired preparations per day (low and high GI). The attributes of appearance, taste, smell, and texture of salads, main course, and desserts, as well as those of the full lunch, were evaluated using a hedonic scale of 7 and 9 points. Lunches with a high GI (90 ± 20.5 %) were modified by changing types of food ingredients, and/or by using culinary techniques to provide a low-GI counterpart with 47 ± 5.9 % GI (p < 0.001). All the preparations were classified as optimal, exceeding the established cut-off point. The “Legume with CHO” lunch had a higher acceptability level in its low GI version (p = 0.006), while the “Chicken with corn” lunch had it in its high GI version (p = 0.004). There was a preference for low-GI salad appearance (p = 0.003) and dessert flavour (p = 0.024), while high-GI main dishes were better praised for flavour (p = 0.034) and texture (p = 0.012). It is therefore possible to prepare low-GI menus equivalent to their traditional counterparts that are received as generally acceptable, with components and sensory attributes equal to, or even better than typical Chilean cuisine dishes.

          Resumen El objetivo de este estudio fue determinar la aceptabilidad de preparaciones de bajo índice glicémico (IG) diseñadas a partir de aquellas de alto IG de consumo habitual en Chile, elaboradas con mínimos cambios en sus ingredientes y basándose en técnicas culinarias que diminuyen el IG. Doce preparaciones tradicionales de alto IG se eligieron para preparar sus homólogos de bajo IG. Durante 12 días, 20 mujeres en buen estado de salud probaron, de forma aleatoria, 2 preparaciones equivalentes por día (de bajo y alto IG), y evaluaron la aceptabilidad promedio de las ensaladas, los platos principales y los postres, así como el almuerzo completo, a través de una escala hedónica de 7 puntos y una de 9 puntos para evaluar aceptabilidad de los atributos: apariencia, sabor, olor y textura. Los almuerzos de alto IG (90 ± 20,5 %) se modificaron cambiando los tipos de ingredientes y/o las técnicas culinarias, formulando preparaciones homólogas de bajo IG (47 ± 5,9 %, p < 0,001). Todas las nuevas preparaciones se calificaron de óptimas, excediendo el punto de corte establecido. La preparación “legumbres con cereales” obtuvo la más alta aceptabilidad en su versión de bajo IG (p = 0,006), mientras que la preparación “Pollo con choclo” lo hizo en su versión de alto IG (p = 0,004). Hubo mayores preferencias por la apariencia de las ensaladas (p = 0,003) y el sabor de los postres de bajo IG (p = 0,024), mientras que los platos principales fueron mejor valorados en cuanto a sabor (p = 0,034) y textura (p = 0,012) en su versión de alto IG. Por lo tanto, es posible preparar menús de bajo IG equivalentes a sus homólogos tradicionales que son considerados generalmente como aceptables, con componentes y atributos iguales o mejores que las preparaciones tradicionales chilenas.

          Glycemic index of foods: a physiological basis for carbohydrate exchange.

          The determine the effect of different foods on the blood glucose, 62 commonly eaten foods and sugars were fed individually to groups of 5 to 10 healthy fasting volunteers. Blood glucose levels were measured over 2 h, and expressed as a percentage of the area under the glucose response curve when the same amount of carbohydrate was taken as glucose. The largest rises were seen with vegetables (70 +/- 5%), followed by breakfast cereals (65 +/- 5%), cereals and biscuits (60 +/- 3%), fruit (50 +/- 5%), dairy products (35 +/- 1%), and dried legumes (31 +/- 3%). A significant negative relationship was seen between fat (p less than 0.01) and protein (p less than 0.001) and postprandial glucose rise but not with fiber or sugar content.

            International Tables of Glycemic Index and Glycemic Load Values: 2008

            OBJECTIVE—To systematically tabulate published and unpublished sources of reliable glycemic index (GI) values. RESEARCH DESIGN AND METHODS—A literature search identified 205 articles published between 1981 and 2007. Unpublished data were also included where the data quality could be verified. The data were separated into two lists: the first representing more precise data derived from testing healthy subjects and the second primarily from individuals with impaired glucose metabolism. RESULTS—The tables, which are available in the online-only appendix, list the GI of over 2,480 individual food items. Dairy products, legumes, and fruits were found to have a low GI. Breads, breakfast cereals, and rice, including whole grain, were available in both high and low GI versions. The correlation coefficient for 20 staple foods tested in both healthy and diabetic subjects was r = 0.94 (P < 0.001). CONCLUSIONS—These tables improve the quality and quantity of GI data available for research and clinical practice.
