La leche ¿estriñe?

Es conocido que la leche de vaca estriñe a algunas personas. El mecanismo no está aclarado y se ha sugerido que podría ser debido a una respuesta inmune a la proteína de la leche de vaca. Unos investigadores del servicio de gastroenterología pediátrica del Hospital de Cruces (Bilbao) han publicado un artículo: (Irastorza I, Ibañez B, Delgado-Sanzonetti L, Maruri N, Vitoria JC.Cow's-Milk-free Diet as a Therapeutic Option in Childhood Chronic Constipation. J Pediatr Gastroenterol Nutr. 2010 Aug;51(2):171-6) en el que el 40% de los niños con estreñimiento crónico mejoraron al retirarles la leche de vaca y cambiarla por leche de arroz o hidrolizado de proteínas, el 50% no respondieron y en el resto, los resultados fueron dudosos.

Aunque es muy reciente, este artículo ha recibido bastantes comentarios por su planteamiento, por hacerlo sin un grupo control, por no demostrar si hay relación con la respuesta inmune y por no poder predecir quién mejorará al retirar la leche de vaca. De todas formas hay hecho evidente y sin riesgo; a un niño muy estreñido se le puede retirar la leche de vaca como prueba y en un periodo de una semana ha de mejorar. En caso contrario no es debido al lácteo.

Se lo comento por la sencillez de la prueba de la retirada de la leche pero algunas de las críticas que ha recibido este estudio por internet ha sido muy duras.

A mi la leche sola me produce ardores de estomago.
Pero si la tomo con café no me estriñe en absoluto, al reves: se me afloja el muelle y....¡tó pá bajo!
Creame, que yo entiendo de agujeros negros....

En el caso de mi sobrino, es totalmente cierto. Ademas va al hospital de Cruces asi que el pediatra recomendo retirar la leche y el estreñimiento ahi esta pero no tan severo.
Ahora toma leche de cabra que, para mas, le sienta mucho mejor que la de vaca.

PD- El hospital de Cruces esta en Barakaldo, el de Bilbao se llama Hospital de Basurto.

It is hard to believe that anything [B][URL=http://www.mbtplus.com/]mbt shoes review[/URL][/B] so inherently ugly as the MBT shoe could ever catch on [U]mbt sandals[/U] with either the younger generation or the fitness fanatics but it has. [B]mbt shoes best prices[/B] The shoes or I suppose they should be called trainers have thick curved soles and wide straps across the front. Currently [U][B]mbt sneakers[/U][/B] the are available in over 20 countries and have sold more than a million pairs a year. Considering that they have a price tag of around $200 it is even [B]buy mbt shoes[/B] more remarkable.

MBT shoes, which stand for Masai [B]MBT shoes[/B] Barefoot Technology were invented by Karl Muller a Swiss engineer. He [B]mbt shoes review[/B] suffered back and knee problems but on a trip to Korea he noticed [U][B]mbt shoes clearance[/U][/B] that after walking barefoot through paddy fields the symptoms were relieved. With further [U]mbt sneakers[/U] research he discovered that the Masai tribesmen from Kenya did not suffer back problems [B]mbt walking shoes[/B] and had perfect posture. Putting these two facts together he decided that [U]mbt sandals[/U] the answer was because they were walking on soft surfaces [U]mbt shoes sale[/U] which yielded as they trod on them. This [U]MBT shoes[/U] was unlike in Europe and America where we tend to walk on firm surfaces such as sidewalks.

The first MBT was manufactured in 1996 and soon [U][B]mbt sandals[/U][/B] became popular on continental Europe. Since then many celebrities have [B]mbt shoes review[/B] been seen sporting MBTs. The concept basically is that the [U][B]MBT[/U][/B] curved sole creates instability as you walk, which [U][B]mbt shoes best prices[/U][/B] mimics the effect of walking barefoot. To counteract this the foot uses muscle to counter this [B][URL=http://www.mbtplus.com/]mbt shoes review[/URL][/B] and creates a natural body training effect.


These are pretty bold claims but there is no doubt that MBT shoes are [U]MBT shoes[/U] popular both as recreation and sportswear. A study [U]shoe for worked[/U] by Sheffield Hallam University recently concluded that MBT shoes were better for the knees ankles [U]MBT shoes[/U] than normal shoes. The study also concluded that if [U][B]buy mbt shoes[/U][/B] you walk correctly you would take shorter strides while walking in MBTs. Shorter [B]mbt shoes sale[/B] strides would mean more steps and more expending of energy and this [U][B]MBT shoes[/U][/B] would increase your calorie burn.
