Pregnancy is a special period of life, and diet should also change accordingly. And look at dietary taboos 25 pregnant women to see what matters need to pay attention to superior pregnancy. First, not a high-fat diet A large number of medical research data confirm that breast cancer, ovarian cancer and cervical cancer have a family genetic predisposition. If a pregnant woman has a long-term high-fat diet, her risk of cancerous reproductive system cancer is bound to increase. Medical scientists point out that although fat itself does not cause cancer, long-term consumption of high-fat foods will increase the concentration of bile acids and neutral cholesterol in the large intestine. Accumulation of these substances can induce colon cancer. At the same time, high-fat foods can increase the synthesis of prolactin, promote breast cancer, and adversely affect maternal and child health. Second, not a high protein diet According to medical research, the lack of protein supply makes it easier for pregnant women to suffer from physical weakness, slow fetal growth, delayed postpartum recovery of health, and poor milk production. Therefore, the daily protein requirement of pregnant women should reach 9O-100 grams. However, high-protein diet during pregnancy can affect the appetite of pregnant women, increase the burden on the gastrointestinal tract, and affect the intake of other nutrients, so that dietary nutrition is out of balance. Studies have confirmed that excessive intake of protein, the human body can produce a large number of harmful substances such as hydrogen sulfide, histamine, easily cause abdominal distension, loss of appetite, dizziness, fatigue and so on. At the same time, excessive protein intake can not only increase the nitrogen content in the blood, but also lead to an increase in cholesterol, which aggravates the renal glomerular filtration pressure. Some people think that the excessive accumulation of protein in the human connective tissue can cause degeneration of tissues and organs, making it more susceptible to cancer. Third, difficult to high sugar diet Scientists from the National Institute for Pisa Research in Italy found that pregnant women with high blood glucose levels have the potential to give birth to overweight fetuses, the incidence of fetal congenital malformations, the chance of pregnancy toxaemia, or the number of cases requiring caesarean section. 3 times, 7 times, and 2 times lower for pregnant women in the low group. On the other hand, pregnant women during the pregnancy can have different degrees of reduction of renal function, if the blood sugar is too high will increase the pregnant women's kidney burden, unfavorable during pregnancy. A large number of medical studies have shown that excessive intake of sugar will weaken the body's immunity, so that pregnant women's body resistance to disease is reduced, susceptible to bacteria, virus infection, is unfavorable. Fourth, not a high calcium diet Pregnant women blindly carry out high-calcium diets, drink large quantities of milk, and add calcium tablets, vitamin D, etc., which are harmful to the fetus. Nutritionists believe that pregnant women oversupply calcium, the fetus is likely to have hypercalcemia, after birth, children will be too early to close the fontanelle, widened and prominent cheekbones, Qiu sloping, narrowing of the aorta, not only unfavorable Healthy growth and development, but also damage the face of future generations bodybuilding. In general, pregnant women need 800 mg of calcium per day in the first trimester of pregnancy and 1,100 mg in the later period. This does not require special supplements, as long as reasonable intake from daily fish, meat, eggs and other foods is sufficient. Fifth, not excessive salty food Some pregnant women have a taste for salty foods because of their dietary habits. In particular, the northern residents are more serious and have more salty food. Modern medical research believes that there is a certain relationship between the amount of salt eaten and the incidence of hypertension. The more salt intake, the higher the incidence of hypertension. As we all know, pregnancy-induced hypertension syndrome is a special disease that occurs when a woman is pregnant. The main symptoms are edema, hypertension, and proteinuria. Severe cases may be accompanied by headaches, vertigo, chest tightness, dizziness, and other symptoms. Occurrence of eclampsia endangers maternal and child health. Therefore, excessive salty food for pregnant women can easily trigger pregnancy-induced hypertension syndrome. For pregnancy care, experts recommend daily salt intake should be about 6 grams. Six, not an acidic diet In early pregnancy, pregnancy tears may present with early pregnancy symptoms such as cravings, loss of appetite, nausea, and vomiting. Many people tend to have an acidic diet. However, scientists from the Federal Republic of Germany found that fetal acidity during early pregnancy is low, and that the mother’s intake of acidic drugs or other acidic substances tends to accumulate in fetal tissue, affecting the normal division, proliferation, and development of embryonic cells, and it is easy to induce inheritance. Substance mutations lead to abnormal fetal development. In late pregnancy, due to the maturation of the fetus, the acidity and alkalinity of its tissue cells are close to that of the mother, and the affected harm is correspondingly smaller. Therefore, pregnant women should not take acidic medicines, acidic foods, acidic beverages, etc. for about 2 weeks during the first trimester of pregnancy. Seven, it is not appropriate to abuse warm supplements Because of the increase in blood flow in the whole blood circulation of pregnant women, the burden on the heart is increased, and blood vessels in the cervix, vaginal wall, and fallopian tubes are also in a state of expansion and congestion. In addition, the maternal endocrine function is prosperous, and the secretion of aldosterols increases, which can easily lead to water and sodium retention and edema and hypertension. In addition, due to the reduction of gastric acid secretion in pregnant women, gastrointestinal function weakened, there will be loss of appetite, stomach flatulence, constipation and so on. Under such circumstances, if pregnant women often take warm tonics and supplements, such as ginseng, pilose antler, deer tire glue, antler, longan, litchi, walnut meat, etc., it will inevitably lead to yin deficiency and impotence. Qi Sheng consumption, blood stasis, increased morning sickness, edema, hypertension, constipation and other symptoms, and even miscarriage or stillbirth. Eight, should not eat mildew food When pregnant women eat agricultural and sideline products contaminated with mycotoxins and foods, not only acute or chronic food poisoning can occur, but it can even cause fetal harm. Because embryo implantation occurs in the early 2 to 3 months of pregnancy, the embryonic body cells are in a highly proliferative and differentiated stage. Due to the invading mycotoxins, the chromosomes break off or become distorted, and some of them stop developing and cause stillbirth and miscarriage. The occurrence of genetic diseases or fetal malformations, such as congenital heart disease, congenital silliness and so on. On the other hand, in the fetal period, due to imperfect function of various organs, especially liver and kidney function is very weak, mycotoxins will have toxic effects on the fetus, affecting development. A large number of medical studies have confirmed that mycotoxin is a strong carcinogen that can cause cancers such as liver cancer and stomach cancer in the mother and child. In addition, maternal coma, vomiting and other symptoms occur due to food poisoning, which is extremely unfavorable to the normal growth and development of the fetus. Nine, not long-term vegetarian Some pregnant women are in favor of fetal development in order to pursue the body's "fitness" during pregnancy, or due to economic conditions, long-term vegetarianism. According to the study, no attention is paid to nutrition during pregnancy. Due to insufficient protein supply, the number of fetal brain cells can be reduced, affecting the intelligence of the future, and the fetus can also be deformed or malnourished. If the intake of fat is insufficient, it will easily lead to the birth of a low-weight fetus, the baby's resistance is low, and the survival rate is low. For pregnant women, anemia, edema and high blood pressure may also occur. Japanese medical scientists have found that infants born to women who eat vegetarian food often suffer from irreversible brain damage due to lack of vitamin B12. After the baby is born for three months, it gradually shows feelings of indifference and loss of ability to control the stability of the head. There are involuntary movements such as the head and wrist. If they are not treated, they can easily cause significant neurological damage to megaloblastic anaemia. Ten, should not drink spicy drinks Medical research confirmed that pregnant women drinking can make alcohol through the placenta into the fetus, directly to the fetus has a toxic effect, not only to slow the development of the fetus, but also can cause some organs of the deformities and defects, such as small head, small eyes, short chin, The brain is narrow, flat, short, and even deformed in the heart and limbs. Some fetuses are born with mental retardation, stupidity, proneness to illness, etc., and even cause offspring to be sick for life. While pregnant women drink tea, because tea contains a lot of tannins, can be combined with the protein in the food, become insoluble tannic acid salt, and can be aggregated with other food nutrients and precipitate, affect pregnant women, fetal protein Absorption and utilization of iron, iron, and vitamins cause malnutrition. Tea also contains a lot of tannic acid, a convergence effect, affecting the intestinal peristalsis, easy to make pregnant women have constipation. Pregnant women drink more soft drinks, can cause iron deficiency and anemia in the body, unfavorable maternal and child. In addition, pregnant women should not drink cold drinks, eat cold food, to prevent fetal movement and abdominal pain and diarrhea in pregnant women. Eleven, want children to drink "Coke" Scientists at the Harvard Medical School in the United States conducted a trial of killing sperm on the three different Coca-Cola beverages currently sold. They concluded that newly-married men drinking cola beverages would directly harm sperm and affect men’s fertility. ability. If the injured sperm is bound to the egg, it may cause fetal malformation or congenital deficiency. The medical scientists added living sperm into a certain amount of cola drinks and measured the survival rate of sperm one minute later. Experiments have shown that the new formula of cola beverage can kill 58% of sperm, while the early formula of cola beverage can completely kill sperm. They also offered advice to newlywed women drinking cola drinks and advised them to drink less or not. Because most cola-type beverages contain caffeine, it is easily absorbed into the fetus through the placenta in the body, endangering the fetus's brain, heart and other important organs, also make the fetus teratogenic or suffering from congenital dementia. Therefore, experts recommend that newly-married couples and couples who want children should not drink coke-type beverages except for tobacco and alcohol. Twelve, pregnant women should not be excessive nutrition Pregnant women properly improve their diet and increase their nutrition, which can enhance their physical fitness and promote fetal development. However, if there is excess nutrients, it will be very harmful. Simply pursuing nutrition and over-nutrition results in high blood pressure in pregnant women, and the fetus is oversized (over 3,500 grams, becoming a huge child). The maternal mortality rate in our country is 0.488 ‰, which is mainly caused by high blood pressure in pregnancy; the other reason is the complications caused by the “great childâ€, the prolonged delivery period, and postpartum hemorrhage. Therefore, pregnant women should not be over-nutrition.
