RESUMO

Objective: Estimate the agronomic area susceptible to the cultivation of V. unguiculata in the Mexican territory to support the establishment of a future agroindustry oriented towards obtaining protein hydrolysates with bioactivity obtained from V. unguiculata.Methods: For the determination of areas with agroclimatic aptitude, three fundamental aspects were considered, which are the following: determination of the agroecological requirements; obtaining spatial information and finally data processing. For the latter, the free license QGIS 3.6.0 Noosa software was used.Results-Discussion: Based on what was found with the data processing, it is clear that most areas of the country have optimal soil conditions, altitudes and hours of light per year; but this is not the case of the average annual temperature and the average annual rainfall required to cultivate Vigna; this areas are localized in the tropical and subtropical areas of the country.Conclusions: More than thirteen million hectares susceptible to being cultivated with V. unguiculata where detected in Mexico. Cultivation in a fraction of this enormous extension could provide raw material to obtain protein hydrolysates with bioactivity required for a future industrial activity.(AU)


Objetivo: Estimar el área agronómica susceptible al cultivo de V. unguiculata en el territorio mexicano para apoyar el establecimiento de una futura agroindustria orientada en la obtención de hidrolizados proteínicos con bioactividad obtenidos de la misma V. unguiculata.Método: Para la determinación de áreas con aptitud agroclimática se consideraron tres aspectos fundamentales que son los siguientes: determinación de los requerimientos agroecológicos; obtención de información espacial y finalmente el procesamiento de los datos. Para esto último se utilizó el software QGIS 3.6.0 Noosa de licencia libre.Resultados: Con base en lo planteado con el procesamiento de datos se observó que en la mayor parte del país se tienen condiciones óptimas de suelo, altitudes y horas luz por año, no así en el caso de la temperatura media anual y la precipitación media anual que están más localizadas en las áreas tropicales y subtropicales del país.Conclusiones: Se detectaron más de trece millones de hectáreas susceptibles de ser cultivadas con V. unguiculata en México. El cultivo en una fracción de esta enorme extensión, puede aportar materia prima para la obtención de hidrolizados proteínicos con bioactividad requeridos por una futura actividad industria.(AU)

RESUMO

Introducción: La malnutrición afecta el crecimiento y desarrollo del ser humano. La falta de conocimiento sobre alimentación y nutrición es uno de los principales desencadenantes de este padecimiento. Este problema afecta a México, acrecentándose en áreas rurales. Objetivos: Evaluar el impacto de un programa educativo para modificar conocimientos, actitudes y prácticas sobre alimentación y nutrición en mujeres adultas campesinas de zonas rurales. Métodos: Se seleccionaron dos comunidades rurales del sur del estado de Yucatán, México. Se hizo un diagnóstico nutricional mediante antropometría asociado al nivel socioeconómico; y se aplicó una Intervención de Orientación Alimentaria con pre y post prueba. Las diferencias entre las variables antropométricas y sociales en cada localidad se calcularon con estadística no paramétrica (χ2). Las calificaciones obtenidas en la pre y postprueba fueron comparadas analizándose en función de la edad, nivel educativo de las participantes y estado civil. Los análisis se facilitaron empleando un paquete estadístico. Resultados: Los datos globales indicaron en promedio, que se trató con mujeres jóvenes, con un nivel educativo bajo, viviendo una relación de pareja bajo el régimen matrimonial, siendo de reducida estatura y mostrando signos de sobrepeso y obesidad el 62.5% de las participantes incidiendo en situaciones de riesgo nutricional. Las calificaciones de la pre y post prueba no se vieron afectadas por la edad de las participantes (p>0,05), pero el nivel educativo influenció a estas variables (p<0,05). El estado civil no afectó significativamente ninguna de las dos calificaciones. La Intervención en Orientación Alimentaria favoreció de manera positiva y significativa cambios sobre conocimientos en alimentación saludable (p< 0,01). Discusión: La aplicación de intervenciones en nutrición como la empleada en este trabajo representan una herramienta importante para coadyuvar a revertir el fenómeno de obesidad manifestado en la población mexicana, sobre todo en el área rural. Esta alternativa de solución debe complementarse con políticas que promuevan la comercialización de alimentos equilibrados y no lo contrario. Conclusiones: La aplicación de una Orientación Alimentaria aumentó significativamente el nivel de conocimientos sobre una alimentación saludable


Introduction: Malnutrition is a key factor affecting growth and development of humans. Lack of knowledge on feeds and nutrition is one of the main reasons that triggers this problem. Malnutrition affects countries like Mexico being bigger in rural areas. Objective: Evaluate the impact of an educational intervention to modify knowledge, attitudes and practices on feeding and nutrition, in rural female adults. Methods: Two rural communities located in the south of Yucatán State were chosen. A nutritional diagnosis was made by means of anthropometry associated to the socioeconomic level; and a Food Orientation Intervention was applied with pre and post test. The differences between the anthropometric and social variables in each location were estimated using non-parametric statistics (χ2). The grades obtained in the pre and post test were analyzed in function of age, educational level of the participants and their marital status. Analysis were facilitated by the use of a statistical package. Results: Overall data from both communities indicated that, on average target population consisted of young women, with a low educational level, living in a marriage relationship, having a low height and showing 62,5% of them signs of overweight and obesity which induced a nutritional health risk. The pre and post test scores were not affected by the age of the participants (p>0,05), but the educational level influence these variables (p<0,05). Marital status did not significantly affect either score. The educational intervention improved knowledge on the importance of a healthy diet (p<0,01). Discussion: The application of nutrition interventions such as the one used in this work represent an important tool to reverse the phenomenon of obesity affecting the Mexican population, especially in rural areas. This tool must be complemented with policies that promote the commercialization of balanced foods and not the opposite. Conclusions: The implementation of a Food Orientation Intervention program, turned into a significant increase in the level of knowledge of a healthy diet

RESUMO

INTRODUCTION: the change in lifestyle and nutrition has led to growing obesity; in Mexico there has been significant increase in its prevalence. The problem was thought limited to adult population, but it also affects children, adolescents and young adults. Obesity at an early stage of life, subsequently leads to obesity in adult life. Apparently few attempts with College students have being reported. OBJECTIVES: relate the effect of anthropometry and physical condition with dietary habits, physical activity and smoking addiction in students of a public university of Mexico, in order to establish a diagnosis of their nutritional status. METHODS: one hundred and seventy eight students, were measured obtaining: body weight, height, waist and hip circumference, body composition and blood pressure. A questionnaire to determine their physical activity was applied, a dietary assessment was also collected and socioeconomic status was established. Data were analyzed statistically by the method of least squares. RESULTS AND DISCUSSION: individuals classified as over-weighted, with obesity class 1 and class 2, accounted for 48.87% of the total population; more overweight and obesity was found in men compared with women, affecting negatively the value of blood pressure. This deteriorating health was attributable to poor eating habits: skipping breakfast and consumption of fast food. Smoking was revealed as a major risk factor since it adversely affected nutritional status.


Introducción: el cambio en el estilo de vida y la nutrición ha dado lugar a una creciente obesidad; en México se ha registrado un notable incremento en su prevalencia. El problema se creía limitado a la población adulta, pero también está presente en niños, adolescentes y en adultosjóvenes. La obesidad en una etapa inicial de la vida adulta, conlleva a su desarrollo posteriormente. Se han llevado a cabo pocos estudios con estudiantes universitarios. Objetivos: relacionar el efecto de la antropometría y de la condición física con los hábitos alimentarios, la actividad física y el tabaquismo de estudiantes de una universidad pública de México con la finalidad de establecer un diagnóstico del estado nutricional. Métodos: ciento setenta y ocho estudiantes participaron, obteniéndose su peso, altura, circunferencia de la cintura y cadera, composición corporal y presión arterial. Se aplicó un cuestionario para conocer su actividad física, se realizó una evaluación dietética y se estableció su nivel socioeconómico. Los datos se analizaron estadísticamente mediante el método de mínimos cuadrados. Resultados y Discusión: los individuos que se clasificaron en sobrepeso, obesidad clase 1 y obesidad clase 2, representaron el 48.87% del total, observándose más sobrepeso y obesidad en los hombres en comparación con las mujeres, reflejándose en un elevado valor de la presión arterial. Este deterioro en la salud se pudo atribuir a malos hábitos alimentarios como el hecho de no realizar el desayuno, así como dedicarle poco tiempo al consumo de alimentos, adquiriendo comida rápida. El tabaquismo se reveló como un factor de riesgo importante, ya que afectó negativamente al estado nutricional.

RESUMO

Hypertension is one of the most common worldwide diseases in humans. Angiotensin I-converting enzyme (ACE) plays an important role in regulating blood pressure and hypertension. An evaluation was done on the effect of Alcalase hydrolysis of defatted Jatropha curcas kernel meal on ACE inhibitory activity in the resulting hydrolysate and its purified fractions. Alcalase exhibited broad specificity and produced a protein hydrolysate with a 21.35% degree of hydrolysis and 34.87% ACE inhibition. Ultrafiltration of the hydrolysate produced peptide fractions with increased biological activity (24.46-61.41%). Hydrophobic residues contributed substantially to the peptides' inhibitory potency. The 5-10 and <1 kDa fractions were selected for further fractionation by gel filtration chromatography. ACE inhibitory activity (%) ranged from 22.66 to 45.96% with the 5-10 kDa ultrafiltered fraction and from 36.91 to 55.83% with the <1 kDa ultrafiltered fraction. The highest ACE inhibitory activity was observed in F2 (IC50 = 6.7 µg/mL) from the 5-10 kDa fraction and F1 (IC50 = 4.78 µg/mL) from the <1 kDa fraction. ACE inhibitory fractions from Jatropha kernel have potential applications in alternative hypertension therapies, adding a new application for the Jatropha plant protein fraction and improving the financial viability and sustainability of a Jatropha-based biodiesel industry.

RESUMO

Jatropha curcas L. protein hydrolysates were produced by treatment of a non-toxic genotype with Alcalase as well as the digestive enzymes pepsin and pancreatin. The J. curcas protein hydrolysate produced with the pepsin-pancreatin system from protein isolate had the highest TEAC value and was shown to undergo single-electron transfer reactions in the ABTS(+) reduction assay, demonstrating its antioxidant capacity. Testing of antimicrobial activity in the J. curcas protein hydrolysates against seven bacterial pathogens showed no growth inhibitory effect in Gram-negative and Gram-positive bacteria. More ACE-I inhibitory active peptides were produced in the Alcalase hydrolysates obtained from J. curcas protein isolate. The protein hydrolysate obtained with Alcalase from defatted J. curcas flour as well as from the protein isolate showed the highest inhibitory effect of ADP-induced aggregation of human platelets in platelet-rich plasma. It is expected that the information collated will facilitate new applications of proteins present in Jatropha plant.

RESUMO

A possible cause associated with urinary lithiasis (UL) is the bioaccumulation of heavy metals in the kidney. The aim of this study was to evaluate the content of Cu, Pb, and Cd in kidney tissues removed from patients with nephrological problems and associate it with UL. Samples of 50 kidney sections from patients were analyzed. Results were statistically analyzed using a fixed effects model including the overall mean, the effect of the health status of patients (with or without UL), gender (male and female), the interaction between both factors and the random error (NID (0, σ (2))). Cu level was 8.8 ± 4.4 mg/kg (mean ± DS) and 25.5% of samples had levels above normal. Lead content in 97.9% of the samples (3.6 ± 1.5 mg/kg) was above normal. All results of Cd (13.2 ± 16.6 mg/kg) were below the maximum permissible limits. There was no difference in the amount of heavy metals on patients with or without UL (P > 0.05) nor depending on the gender (P > 0.05). It was concluded that there is no apparent relationship between a very elevated level of Cu or Pb in the kidney on the development of UL.

RESUMO

El objetivo de este trabajo fue diseñar y evaluar el efecto de una intervención de orientación alimentaria en un grupo de migrantes de retorno en el área rural de Yucatán, México. Se trabajó con 54 sujetos seleccionados a través de un muestreo no probabilístico entres comunidades del centro el Estado. Se desarrolló un material didáctico que constó de siete lecciones de nutrición en las cuales se incluyeron conceptos referidos en el Modelo Creencias en la Salud y la Teoría Social Cognitiva. Las lecciones se aplicaron a un grupo de intervención (n=27), teniendo otro como testigo(n=27). El efecto pre y post test de la intervención, fue evaluado mediante un cuestionario de conocimientos, cuyos datos se analizaron con la prueba de Wilcoxon. Para comparar las diferencias entre grupos, antes y después de intervención se utilizó el estadístico UMann-Whitney. La orientación alimentaria propició un incremento significativo (p < 0,05) en las calificaciones finales del grupo de intervención después de haber sido instruido. Así mismo, las puntuaciones de este grupo fueron superiores (p < 0,05) en el post test al compararlas con las del grupo testigo, lo cual demuestra la efectividad de la intervención (AU)


The aim of this work was to develop and evaluate the effect of a nutrition education intervention in a group of return migrants workers at rural areas of the State of Yucatán, México. The study included 54 subjects who were selected through non-probabilistic sampling in three communities in the center of the State. Didactic material was developed which consisted of seven lessons in nutrition including concepts mentioned in the Health Belief Model and the Social Cognitive Theory. The lessons were applied to an intervened group (n = 27), taking other as control (n = 27).The pre and post test effect of the intervention was evaluated using a questionnaire, which was tested statistically with the Wilcoxon test. To compare differences between groups before and after intervention Mann-Whitney U statistic test was used. The didactic material produced a significant increase (p < 0,05) in the knowledge ratings in the intervention group after being instructed. In addition, this group scores were higher (p < 0,05) in the post test when compared with the control group, demonstrating the effectiveness of the intervention (AU)

RESUMO

BACKGROUND: Enzymatic proteolysis of food proteins is used to produce peptide fractions with the potential to act as physiological modulators. Fractionation of these proteins by ultrafiltration results in fractions rich in small peptides with the potential to act as functional food ingredients. The present study investigated the angiotensin-I converting enzyme (ACE-I) inhibitory and antioxidant activities for hydrolysates produced by hydrolyzing Vigna unguiculata protein extract as well as ultrafiltered peptide fractions from these hydrolysates. RESULTS: Alcalase(®), Flavourzyme(®) and pepsin-pancreatin were used to produce extensively hydrolyzed V. unguiculata protein extract. Degree of hydrolysis (DH) differed between the enzymatic systems and ranged from 35.7% to 58.8%. Fractionation increased in vitro biological activities in the peptide fractions, with IC(50) (hydrolysate concentration in µg protein mL(-1) required to produce 50% ACE inhibition) value ranges of 24.3-123 (Alcalase hydrolysate, AH), 0.04-170.6 (Flavourzyme hydrolysate; FH) and 44.7-112 (pepsin-pancreatin hydrolysate, PPH) µg mL(-1), and TEAC (Trolox equivalent antioxidant coefficient) value ranges of 303.2-1457 (AH), 357.4-10 211 (FH) and 267.1-2830.4 (PPH) mmol L(-1) mg(-1) protein. CONCLUSION: The results indicate the possibility of obtaining bioactive peptides from V. unguiculata proteins by means of a controlled protein hydrolysis using Alcalase(®), Flavourzyme(®) and pepsin-pancreatin. The V. unguiculata protein hydrolysates and their corresponding ultrafiltered peptide fractions might be utilized for physiologically functional foods with antihypertensive and antioxidant activities.

RESUMO

El objetivo de este trabajo fue realizar un diagnóstico del estado de salud y nutrición en un grupo de migrantes de retorno en el área rural de Yucatán. Ochenta y cuatro migrantes que regresaron de EE.UU., fueron seleccionados a través de un muestreo aleatorio con estratificación en tres comunidades del centro del Estado, en quienes se aplicaron métodos antropométricos, técnicas clínicas y encuestas dietéticas. Los resultados revelaron una media del IMC de 30,2 ± 4,8 kg/m2, correspondiendo a la clasificación de obesidad tipo I. Los datos hallados de circunferencia de cintura denotaron adiposidad central excesiva en la mayoría de los sujetos, donde el 66,7% presentó un perímetro de cintura mayor a los límites establecidos de alto riesgo. Las enfermedades cardiometabólicas de mayor presencia fueron la hipertrigliceridemia e hipertensión arterial con una prevalencia del 36,9% y 33,3%, respectivamente. Más del 50% de la muestra presentó una dieta de alta densidad energética y una desproporción en la ingesta de macro nutrimentos, sobresaliendo el consumo deficiente en proteínas y fibra dieté- tica, con exceso en la ingesta de colesterol y sodio, según la IDR. En conclusión, se puede considerar un grupo de riesgo nutricio de acuerdo a los problemas de peso, adiposidad central elevada y comorbilidades encontradas, así como, por el desequilibrio en el patrón alimentario hallado (AU)


The aim of this work was to diagnose the state of health and nutrition in a group of return migrants in rural areas of the State of Yucatán. Eighty-four migrants who returned of U.S., were selected through stratified random sampling in three communities in the center of the State, in whom anthropometric methods, clinical techniques and dietary surveys were applied. The results indicate a mean BMI of 30,2 ± 4,8 kg/m2 corresponding to a type I obesity. The data found on waist circumference denote excessive central adiposity in most subjects, so that 66,7% had a waist circumference greater than the limits of high risk. The prevalence of cardiometabolic diseases like hypertriglyceridemia and arterial hypertension was 36,9 and 33,3%, respectively. More than 50% of the sample presented a diet of high energy density and disproportion in the intake of macro nutrients; poor consumption in proteins and fiber with excess cholesterol and sodium intake according to DRI. In conclusion, it can be considered a nutritional risk group according to weight problems, high central adiposity and comorbidities encountered, as well for the imbalance in the dietary patterns found (AU)
