Women pregnancy should eat less meat

Many women to birth to healthy babies, pregnancy began before increasing the intake of protein and other nutrients. But according to the BBC (United Kingdom broadcasting company) reported that the United States scientists found that high levels of protein in the diet reduces women pregnancy success rates.

By the Director of the Colorado Center for reproductive medicine research group led by Dr David Gardner found, if the content of protein in the diet than 25%, it will interfere with the normal imprinting in early embryonic development in mice, affects embryo implantation and fetal development.

Dr Gardner female mice were divided into two groups, the first group of feed protein content of 25% food, food with the second group of protein content in feed 14%. 4 weeks later, he makes these females mate and will be porting 174 blastocysts to surrogate female mice, to check if the mother\'s diet before the embryo implantation effects on fetal development. Found that in the first group of female mice blastocyst, only 36% shows a normal genetic imprinting, while the second group of 70%. In the first group of female mice blastocyst, only the 65% in transplantation to pregnant female mice later develop into a fetus within the uterus and the second is 81%. 84%, the first group of female rat fetuses only further development, the second group of 99%. In addition, Gardner also surrogate pregnant female rats fifth day to analyze the embryos, found that first group of female rats of fetal growth slower than the second group of female rat fetal one-third days.

In fact, previous research has found that, within the reproductive organs of female cow protein metabolism product---increased content of ammonium alters the H19 imprinting of genes, and the H19 gene plays an important role in embryonic development. Although research is still conducted in mice, but Dr Gardner believes that research results to humans as a reference. \"High protein content in recipes, ammonium content would be a corresponding increase in the reproductive system, thus affecting the normal H19 gene imprinting and fetal development, and leads to increased risk of miscarriage. For women who want to children, protein intake should not exceed the total energy of the 20%. \"High protein food including meat, eggs, milk, beans, daily food.
