Too high protein will reduce the pregnancy rate.
In order to have a healthy baby, most women begin to increase the intake of nutrients in protein before pregnancy. However, according to the BBC, American researchers found that the high content of protein in the diet reduced the passing rate of women during pregnancy. According to the scientific research led by Dr. David Gardner, the head of Colorado Reproductive Medicine Center, if the content of protein in the diet exceeds 25%, it will affect the conventional gene imprinting in the early embryonic development of mice and endanger the implantation of fertilized eggs and the development of babies.
Dr Gardner divided female insect mice into two groups. The first group was fed with food with protein content of 25%, and the second group was fed with food with protein content of 65,438+04%. Four weeks later, he bred the female mouse and transplanted 174 blastocysts into the female mouse born by abdomen to check the harm of the diet of the female mouse to the baby's development before the fertilized egg was implanted.
The experimental data showed that only 3.50% of the blastocysts of the first batch of female rats showed conventional genetic imprinting, while the second batch showed 70%. After the blastocysts of the first batch of female rats were transplanted into the uterus of female rats born by abdominal borrowing, only 65% grew into fetal rats, and the second batch was 865,438+0%. Only 84% of the fetuses of the first batch of female rats developed further, and the second batch was 99%. In addition, Dr. Gardner is still analyzing the embryonic development process of female rats born by abdomen on the fifth day of pregnancy. The results showed that the growth and development of the first batch of female rats were slower than that of the second batch of female rats 1/3 days.
There are also high-protein foods in meat products.
This shows that the previous scientific research found that the increase of protein's metabolite-ammonium in the male reproductive organs of female insects and dairy cows will change the imprint of H 19 gene, and H 19 gene stimulation plays a key role in embryo development. Although the current discussion is still on mice, Dr. Gardner feels that the conclusions of scientific research are equally meaningful to people. "If the protein content in the diet is too high, the composition of ammonium in the urinary system will increase relatively, which will affect all the normal impressions of the H 19 gene and the baby's development, and increase the probability of miscarriage. For some women who want to have children, the intake of protein should not be higher than 20% of the total calories. " The focus of high-protein foods includes meat, eggs, milk, beans and other daily ingredients.
Conclusion: If the content of protein in the diet is too high, the composition of ammonium in the urinary system will increase accordingly, which will further harm all the normal impressions of H 19 gene and the baby's development, and increase the probability of miscarriage. For some women who want to have children, the intake of protein should not be higher than 20% of the total calories.
