          Abstract

          Resumen Introducción: El índice glucémico (IG) cuantifica el aumento de la glucemia que se produce tras la ingesta de alimentos, en relación con la ingesta de glucosa. Ello podría modificarse con el consumo de alimentos funcionales, cuyos componentes afectan funciones del organismo de manera específica y positiva, promoviendo un efecto fisiológico o psicológico, más allá de su valor nutritivo tradicional. El objetivo fue evaluar el efecto glucémico de un pancake funcional elaborado a partir de una mezcla instantánea de avena. Metodología: Se realizó un estudio experimental, desarrollando la fórmula de pancake de avena, se midieron variables como fibra, pH y humedad; empleando cuatro tratamientos variando sus porcentajes de harina de trigo y harina de avena. Se evaluó el índice glucémico del mejor tratamiento de pancake en 7 sujetos, teniendo en cuenta la ingestión de 50 g de carbohidratos disponibles a partir de pancake de avena y como control 50 g de carbohidratos a partir de pan blanco. Se midió el índice glucémico del mejor tratamiento con el cálculo del área bajo la curva de la FAO. Resultados: El índice glucémico del nuevo producto fue bajo, con un 35,6% en promedio de los siete sujetos. Conclusiones: El pancake de avena es un alimento funcional con bajo índice glucémico y alto contenido en fibra, por tanto, se podría recomendar su consumo como opción saludable para la población en general.

          Abstract Introduction: The glycemic index (GI) quantifies the increase in blood glucose that occurs after food intake, in relation to glucose intake. This could be modified with the consumption of functional foods, whose components affect body functions in a specific and positive way, promoting a physiological or psychological effect, beyond its traditional nutritional value. The objective was to evaluate the glycemic effect of a functional pancake made from an instant oatmeal mix. Methodology: An experimental study was carried out, developing the oat pancake formula, variables such as fiber, pH and humidity were measured; using four treatments varying their percentages of wheat flour and oatmeal. The glycemic index of the best pancake treatment was evaluated in 7 subjects, taking into account the ingestion of 50 g of available carbohydrates from oat pancake and 50 g of carbohydrates from white bread as a control. The inclusion criteria were according to the FAO methodology for determining the glycemic index through the area under the curve. Results: The glycemic index of the new product was low, with an average of 35.6% of the seven subjects. Conclusions: The oat pancake is a functional food with a low glycemic index and high fiber content, therefore, its consumption could be recommended as a healthy option for the general population.

          Five-week, low-glycemic index diet decreases total fat mass and improves plasma lipid profile in moderately overweight nondiabetic men.

          To evaluate whether a 5-week low-glycemic index (LGI) diet versus a high-glycemic index (HGI) diet can modify glucose and lipid metabolism as well as total fat mass in nondiabetic men. In this study, 11 healthy men were randomly allocated to 5 weeks of an LGI or HGI diet separated by a 5-week washout interval in a crossover design. The LGI diet resulted in lower postprandial plasma glucose and insulin profiles and areas under the curve (AUCs) than the HGI diet. A 5-week period of the LGI diet lowered plasma triacylglycerol excursion after lunch (AUC, P < 0.05 LGI vs. HGI). These modifications were associated with a decrease in the total fat mass by approximately 700 g (P < 0.05) and a tendency to increase lean body mass (P < 0.07) without any change in body weight. This decrease in fat mass was accompanied by a decrease in leptin, lipoprotein lipase, and hormone-sensitive lipase RNAm quantities in the subcutaneous abdominal adipose tissue (P < 0.05). We concluded that 5 weeks of an LGI diet ameliorates some plasma lipid parameters, decreases total fat mass, and tends to increase lean body mass without changing body weight. These changes were accompanied by a decrease in the expression of some genes implicated in lipid metabolism. Such a diet could be of benefit to healthy, slightly overweight subjects and might play a role in the prevention of metabolic diseases and their cardiovascular complications.

            Dietary Glycemic Index and Load and the Risk of Type 2 Diabetes: Assessment of Causal Relations

            While dietary factors are important modifiable risk factors for type 2 diabetes (T2D), the causal role of carbohydrate quality in nutrition remains controversial. Dietary glycemic index (GI) and glycemic load (GL) have been examined in relation to the risk of T2D in multiple prospective cohort studies. Previous meta-analyses indicate significant relations but consideration of causality has been minimal. Here, the results of our recent meta-analyses of prospective cohort studies of 4 to 26-y follow-up are interpreted in the context of the nine Bradford-Hill criteria for causality, that is: (1) Strength of Association, (2) Consistency, (3) Specificity, (4) Temporality, (5) Biological Gradient, (6) Plausibility, (7) Experimental evidence, (8) Analogy, and (9) Coherence. These criteria necessitated referral to a body of literature wider than prospective cohort studies alone, especially in criteria 6 to 9. In this analysis, all nine of the Hill’s criteria were met for GI and GL indicating that we can be confident of a role for GI and GL as causal factors contributing to incident T2D. In addition, neither dietary fiber nor cereal fiber nor wholegrain were found to be reliable or effective surrogate measures of GI or GL. Finally, our cost–benefit analysis suggests food and nutrition advice favors lower GI or GL and would produce significant potential cost savings in national healthcare budgets. The high confidence in causal associations for incident T2D is sufficient to consider inclusion of GI and GL in food and nutrient-based recommendations.
