Abstract: modern diet tends to change eating habits and there is a tendency to consume more processed foods. these changes in eating habits towards more consumption of processed food, and the recognized benefic effects of dietary fiber by consumers, tend to increase the number of "high fiber" foods in the market. although the beneficial effects of dietary fiber on human health is widely recognized, this increased consumption of dietary fiber may also have adverse effects on digestion, absorption and utilization offood proteins. research in the past has shown that the consumption of high dietary fiber diets have an adverse effect on certain indicators of protein quality. therefore it becomes very important to study the physicochemical properties of the various sources of dietary fiber, as well as the presence of other factors, associated to the fibrous fraction, in their possible negative influence on the protein quality of rich dietary fiber diets.
EFECTO ADVERSO EN LA CALIDAD PROTEICA DE LOS ALIMENTOS DE DIETAS CON ALTO CONTENIDO DE FIBRA DIETARIA ADVERSE EFFECT ON THE FOOD PROTEIN QUALITY OF DIETS HIGH IN DIETARY FIBER

Revista Chilena de Nutricíon , 2011,
Abstract: La dieta moderna cambia los hábitos alimenticios y existe una tendencia al consumo de alimentos más procesados. El cambio de hábito alimentario hacia alimentos más procesados tiende a incrementar, algunas veces por propósitos publicitarios, aquellos alimentos procesados "altos en fibra". Si bien los efectos benéficos de la fibra dietética a la salud humana son ampliamente reconocidos, este aumento en el consumo de fibra dietética puede también tener efectos adversos en la digestión, absorción y utilización de la proteína de los alimentos. En las investigaciones revisadas se obtuvo que el consumo de dietas altas en fibra dietética tiene efecto adverso en ciertos indicadores de calidad proteica, por lo que la inclusión de fuentes proteicas con altos contenidos de fibra impone la necesidad de estudiar las características físico-químicas de la fibra dietética, así como la presencia de factores que pudieran unirse a la fracción fibrosa e influir negativamente en la calidad proteica.

Revista Espa?ola de Salud Pública , 2009, DOI: 10.1590/S1135-57272009000400008
Abstract: background: the canary islands population experiences the highest type 2 diabetes (dm2) mortality in spain. we studied lifestyle, unknown dm2 and treatment adherence in diabetics of these islands. methods: cross-sectional study of 6729 subjects from the general population (age 18-75) that participate in the cohort study "cdc of the canary islands". we found out their medical problems, diet, physical activity, medications, smoking, etc. results: prevalence of dm2 was 12% in men and 10% in women (p=0.005). the disease was unknown in 22% of men and 9% of women (p < 0.001). considering unknown dm2, lack of treatment and lack of adherence, 48% of men and 28% of women did not follow a regular treatment. diabetics' men prevalences of smoking (28%; ci95%=23-33) and sedentariness (62%; ci95%=56-68) were similar to non diabetic men, but obesity was more frequent in diabetics (45 versus 25%; p < 0.001). diabetics women showed a higher obesity (54 versus 27%; p < 0.001) and a lower smoking prevalence (11 versus 22%; p < 0,001) than non diabetics, but they presented a similar sedentariness (75%; ci95%=70-79). in both sexes, energy intake was lower in diabetics (p < 0.001), but 93% of them (ci95%=91-95) showed a high consumption of calories from saturated fat and 69% (ci95%=65-72) presented metabolic syndrome. conclusions: the canarian diabetics are a sedentary and obese population that show a high consumption of saturated fats and high prevalence of metabolic syndrome. the proportion of them following regular treatment is low, specially in diabetic men that, in addition, still smoke.

El óxido nítrico: implicaciones fisiopatológicas en la preeclampsia
Rojo Domínguez,Delia Mercedes; García Bacallao,Lourdes; Clapés Hernández,Sonia; álvarez Corredera,Mayra Silvia;
Revista Cubana de Investigaciones Biom??dicas , 2003,
Abstract: a review of pre-eclampsia, one of the most significant health problems in human pregnancy that complicates approximately 6 to 8 % of pregancies and causes fetal growth retardation, infant morbidity and mortality, premature births and maternal death, was conducted recent studies have reported that there is an unbalance in the oxidative status, an increase of the oxidant systems and a decrease of the antioxidant systems in women with pre-eclampsia, and that this factor may contribute to the pathogenesis of this disease. the nitric oxide is a vasodilative factor and a platelet anti-aggregant that may play an important role on inducing hemodynamic changes during pregnancy. the biochemistry of nitric oxide and its possible interactions with other free radicals was dealt with. studies conducted with rats show that pregnancy is associated with a rise in the production and response to nitric oxide. contradictions have been found among humans as regards the role of nitric oxide in the maternal adaptation to pregnancy. this suggests that nitric oxide may be one of the multiple systems acting in the maintenance of the symbiotic relation between mother and fetus. however, the function of each system may be genetically determined. v

Revista Cubana de Investigaciones Biom??dicas , 2001,
Abstract: Desde la década de los a os setenta se ha producido una explosión en las áreas de investigación y clínica relativas a los radicales libres y los antioxidantes. En este terreno que hasta ayer fue patrimonio de químicos y biólogos fundamentalmente, la medicina se ha introducido a pasos agigantados. El presente trabajo es una revisión bibliográfica acerca de las plantas con acción antioxidante y algunos de los mecanismos por los cuales ellas actúan. Existen plantas que según los reportes populares presentan acción de este tipo, pero en muchos casos no se conoce su composición química Since the 70′s there has been an explosion in research and clinical areas regarding the study of free radicals and antioxidants. This field that till yesterday was controlled by chemists and biologists fundamentally has been rapidly invaded by Medicine. The present paper is a literature review on plants with antioxidant properties and some of their mechanisms of action. It is commonly said that there are plants with such type of action but in most of cases their chemical composition is unknown

El óxido nítrico: implicaciones fisiopatológicas en la preeclampsia
Delia Mercedes Rojo Domínguez,Lourdes García Bacallao,Sonia Clapés Hernández,Mayra Silvia álvarez Corredera
Revista Cubana de Investigaciones Biom??dicas , 2003,
Abstract: Se hizo una revisión de la preeclampsia, uno de los problemas de salud más significativos en el embarazo humano, que complica aproximadamente de 6 a 8 % de los embarazos y además causa retardo del crecimiento fetal, morbilidad y mortalidad infantil, nacimientos prematuros y muerte materna. Estudios recientes han reportado que hay un desbalance en el status oxidativo, aumentados los sistemas oxidantes y los sistemas antioxidantes disminuidos en mujeres con preeclampsia y que este factor pudiera contribuir a la patogénesis de esta enfermedad. El óxido nítrico es un factor vasodilatador y antiagregante plaquetario que puede desempe ar un papel importante al inducir cambios hemodinámicos durante el embarazo. Se trató acerca de la bioquímica del óxido nítrico y sus posibles interacciones con otros radicales libres. Estudios en ratas muestran que el embarazo está asociado con un aumento en la producción y respuesta al óxido nítrico. En humanos se han encontrado contradicciones acerca del papel del óxido nítrico en la adaptación materna al embarazo. Esto sugiere que el óxido nítrico, puede ser uno de los múltiples sistemas que actúan en el mantenimiento de la relación simbiótica entre la madre y el feto. Sin embargo la función de cada sistema puede estar determinada genéticamente.
