Pregnant women, as a special group, in the daily diet, should not only pay attention to strengthening nutrition, appropriate to eat nutritious food, and dietary cooking, food hygiene and food selection and other aspects, should pay attention to the following "ten not", and gave birth to a healthy and intelligent life, and help the main.
First, not high fat diet: a large number of medical research data confirmed that breast cancer, ovarian cancer and cervical cancer have a genetic predisposition to family. If the long-term high-fat diet for pregnant women, dangerous daughter suffering from cancer of the reproductive system is bound to increase. Medical experts point out that fat itself is not carcinogenic, but long-term eating more fatty foods, will make the bile acid and neutral cholesterol concentration in the large intestine, the accumulation of these substances can cause colon cancer. At the same time, high fat foods can increase the synthesis of prolactin, and promote breast cancer, adverse maternal and child health.
Two, not high eggs from diet: medical research believes that the lack of protein supply, easy to make pregnant women physical weakness, fetal growth is slow, postpartum recovery health retardation, milk secretion is rare. The daily protein requirement of pregnant women should be 9O100 grams. However, high protein diet during pregnancy can affect pregnant women's appetite, increase the burden on the gastrointestinal tract, and affect other nutrients intake, so that the nutritional imbalance of diet. Studies have shown that excessive intake of protein, the body can produce a large number of hydrogen sulfide, histamine and other harmful substances, easy to cause abdominal distension, anorexia, dizziness, fatigue and other phenomena. At the same time, excessive intake of protein can not only cause increased nitrogen content in the blood, but also lead to high cholesterol and aggravate the pressure of renal glomerular filtration. Some people believe that proteins accumulate too much in human connective tissue, which can cause degeneration of tissues and organs, which can lead to cancer.
Three, not easy to diet, medical scientists: Italy pizza National Institute found that high blood sugar group, overweight women to give birth to the possibility of fetal congenital malformations, the rate of emergence of toxemia of pregnancy opportunity or need cesarean delivery times, respectively, is blood sugar on the low side group of pregnant women, 3 times, 7 times and 2 times. On the other hand, in pregnant women, the excretion of glucose in the kidney can be reduced to varying degrees. If the blood sugar is too high, it will increase the kidney burden of pregnant women and adversely affect pregnancy health care. A large number of medical studies show that eating too much sugar will weaken the body's immunity, reduce the body's resistance to disease in pregnant women, and be susceptible to infection by pathogens and viruses.
Four, not a high calcium diet: the pregnant Princess blindly high calcium diet, drinking a lot of milk, plus calcium, vitamin D, harmful to the fetus. Nutritionists believe that pregnant women are more likely to have fetal calcium excess, hypercalcemia, after birth, children will be closed early, wide jaw fontanelle and prominent, Qiu Liang forward, coarctation of the aorta, both negative healthy growth, and loss of offspring face aerobics. Generally speaking, pregnant women need 800 mg of calcium per day before pregnancy, and later can be increased to 1100 mg, which does not need special supplementation. Only reasonable intake from daily fish, meat, eggs and other foods is enough.
Five, should not excessive salty food: some pregnant women because of eating habits, like salty food, especially the northern residents more serious, more salty food. Modern medical research believes that the amount of salt is related to the incidence of hypertension. The more people eat salt, the higher the incidence of hypertension. As everyone knows, women in pregnancy induced hypertension syndrome is a special disease during pregnancy before onset, the main symptom is edema, hypertension and proteinuria, can be accompanied by serious headache, vertigo, chest tightness, dizziness and other symptoms, and even eclampsia which endangers maternal and child well-being. Therefore, pregnant women over salty food, easily lead to pregnancy induced hypertension syndrome. For pregnancy health care, experts suggest that the daily intake of salt should be about 6 grams.
Six, should not be acidic food: pregnant tears appear choice food, loss of appetite, nausea and vomiting and other symptoms of early pregnancy in early May, many people like eating acid. However, the scientists found that the Federal Republic of Germany, the low acidity of early pregnancy, maternal intake of acidic drugs or other acidic substances, easily accumulate in fetal tissues, affecting the normal proliferation of embryonic cell development and growth, and easy to induce mutations in the genetic material, leading to development of fetal malformation. In late pregnancy, because the fetus is becoming more mature, the pH of the tissue cells is close to that of the mother, and the harm is less affected. Therefore, pregnant women should not take acidic drugs and acidic foods and acidic beverages for about 2 weeks during the first trimester of pregnancy.
Seven, not among pregnant women due to his warm tonic: the blood circulation system of blood flow was increased, heart burden, cervix, vaginal wall and fallopian tube and other parts of the blood vessels in dilated and congested state. Coupled with the endocrine function of pregnant women exuberant, secretion of aldehydes and sterols increased, easily lead to water, sodium retention and edema, high blood pressure and other diseases. Moreover, pregnant women due to reduced gastric acid secretion, gastrointestinal function decreased, there will be loss of appetite, stomach flatulence, constipation and so on. In this case, if pregnant women often take warm tonic, tonic, such as ginseng, pilose antler, deer glue, antler glue, longan, litchi, walnut meat, will inevitably lead to hyperactivity, difficulty of Qi, Yin consumption, and hemopyretic bleeding, edema, hypertension, aggravate morning sickness, constipation and other symptoms even so, miscarriage or stillbirth.
Eight, should not eat moldy food
