ABSTRACT
Las galletas son actualmente productos de gran demanda, constituyendo un sector sustancial de la industria alimentaria. Considerando la importancia de la buena alimentación y la oportunidad de incorporar leguminosas a productos de panificación como alternativa saludable logrando un mejor balance proteico, se planteó la propuesta de elaborar galletas a base de harina de trigo, sorgo y frijol. El objetivo del presente trabajo fue elaborar y evaluar galletas de harina de trigo sustituidas al 10%, 30% y 100% de harina de sorgo y frijol. Se diseñaron tres formulaciones para la elaboración de galletas al 10%, 30%, 100% de harina de sorgo y harina de frijol y la muestra control 100% trigo. Se realizó la evaluación proximal y perfil instrumental de textura a cada uno de las formulaciones; así mismo, el análisis sensorial para evaluar los atributos de color, olor, sabor y textura por medio de una escala hedónica de siete puntos. El reemplazo parcial de trigo por sorgo 10% - 30% y frijol al 10% fueron las formulaciones más acertadas con un porcentaje promedio de proteínas de 19 a 23%, además de presentar una alta puntuación en la evaluación sensorial. Estas combinaciones de harinas podrían ser utilizadas por la industria alimentaria para producir galletas de buena calidad nutricional, con características físicas y sensoriales aceptables para la población en general(AU)
Nowadays, cookies are in a real high demand, constituting a substantial sector of the food industry. Considering the importance of a good nutrition and the opportunity to incorporate legumes into baking products as a healthy alternative achieving a better protein balance, it was made a proposal to make cookies based on wheat flour, sorghum and beans. The objective of the current work was to elaborate and evaluate wheat flour cookies substituted to 10%, 30% and a 100% of sorghum and bean flour. Three formulations were prepared for the making of the cookies at 10%, 30% and a 100% of sorghum and bean flour and the control sample at a 100% of wheat. The proximal evaluation was made to each of the treatments, as well as the sensorial analysis for the evaluation of color attributes, odor, taste and texture through a hedonic scale of 7 points. The partial replacement of wheat by sorghum 10% - 30% and 10% of bean were the most successful formulations with a protein percentage average of 19 to 23% besides presenting a high score in sensory evaluation. These flour combinations could be used in the food industry for the making of cookies with a well nutritional quality, with physical and sensory qualities acceptable for the general population(AU)

Resumen El propósito de esta revisión es analizar la progresión bioquímica de la placa aterosclerótica y la relación que presenta con la diabetes y la alimentación. Se exponen las evidencias científicas de pacientes con diabetes, que a diferencia de pacientes no diabéticos presentan niveles más elevados de algunos ácidos grasos en la placa de ateroma (como el palmítico, linoleico y oleico), elevada incidencia de trombosis coronaria relacionada con el incremento en el tamaño de la base necrótica y la disminución del tamaño de la capa fibrosa de los ateromas. Entre ambos grupos de pacientes se expone la diferencia en el perfil de lípidos de la placa aterosclerótica, así como los cambios celulares involucrados en la formación de la misma y la influencia de la alimentación sobre su desarrollo.
Abstract The purpose of this review is to analyze the biochemical progression of atherosclerotic plaque and its association with diet and diabetes. This study shows the scientific evidence of demonstrating that diabetic patients present high levels of fatty acids like palmitic acid and linoleic acid in their atheroma plaques in comparison with non-diabetic patients. This study also establishes how patients with diabetes mellitus have a higher prevalence of atherosclerotic heart diseases in the form of Coronary Thrombosis and have different anatomopathological appearance like higher necrotic core and thin fibrotic layer than the general population. Furthermore this review describes the different anatomopathological appearance and cellular changes involved in the formation of these plaques and how diet can affect the development of these plaques.

Background: Undernutrition and obesity coexist among Mexican children due to poverty, sedentariness and inadequate food intake. Aim: To assess the nutritional status of school age children in a Mexican city located in the frontier with United States. Material and Methods: Cross sectional assessment of children from 28 basic schools in 2005, 2008 and 2013. Using a cluster sampling methodology, 5 children per course were selected in each school, reaching a final sample 840 children aged 7 to 12 years old. Body mass index z scores were calculated. Results: The pre valence of overweight and obesity among these children was 49, 54 and 45% in the assessments performed in 2005, 2008 and 2013 respectively. Conclusions: There is a trend towards a decrease in the frequency of obesity in these children from 2005 to 2013.
