What precautions should pregnant women take in spring?

  　Pregnant women should pay attention to what they eat in spring

　　1. High-fat diet is not suitable: Medical scientists point out that although fat itself does not cause cancer, long-term addiction to high-fat foods will increase the concentration of bile acid and neutral cholesterol in the large intestine. The accumulation of these substances can induce colon cancer. At the same time, high-fat foods can increase the synthesis of prolactin and promote the occurrence of breast cancer , harmful to mother and baby healthy . A large amount of medical research data also confirms that breast cancer, ovarian cancer and cervical cancer It has a family genetic tendency and is related to long-term high-fat diet. If a pregnant woman is addicted to high-fat foods, her daughter's risk of reproductive system cancer will be increased.

　　2. High-protein diet is not suitable: Medical research believes that insufficient protein supply can easily weaken the physical strength of pregnant women. fetus Growth is slow, Postpartum Recovery is slow and milk secretion is sparse. Therefore, the daily protein requirement of pregnant women should reach 90-100 grams. However, a high-protein diet during pregnancy can affect the appetite of pregnant women, increase the burden on the gastrointestinal tract, affect the intake of other nutrients, and make the diet nutritionally unbalanced. Research has confirmed that excessive intake of protein can produce a large amount of hydrogen sulfide, histamine and other harmful substances in the human body, which can easily cause abdominal distension, loss of appetite, dizziness, fatigue and other phenomena. At the same time, excessive protein intake can not only increase the nitrogen content in the blood, but also easily lead to an increase in cholesterol and increase the burden on the glomerular filtration function of the kidneys. Some scholars believe that excessive accumulation of protein in the connective tissue of the human body can cause degeneration of tissues and organs, making people susceptible to diseases. cancer。

　　3. Not prone to high-sugar diet: Medical scientists from the National Research Institute in Pisa, Italy, found that pregnant women in the high blood sugar group are more likely to give birth to overweight fetuses, the incidence of fetal congenital malformations, and pregnancy-induced hypertension syndrome The chances of needing a caesarean section were respectively 3 times, 7 times and 2 times that of pregnant women in the hypoglycemia group. On the other hand, the renal sugar excretion function of pregnant women may be reduced to varying degrees during pregnancy. If blood sugar is too high, it will increase the burden on the pregnant woman's kidneys, which is detrimental to health care during pregnancy. A large number of medical studies have shown that excessive intake of sugar will weaken the body's immunity, reduce the disease resistance of pregnant women, and make them susceptible to bacterial and viral infections, which is detrimental to eugenics.

　　4. High-calcium diet is not suitable: Pregnant women blindly consume high-calcium diet, such as taking a large amount of calcium tablets, vitamin D, etc., which is harmful to the fetus. Nutritionists believe that excessive calcium supplementation in pregnant women may cause hypercalcemia in the fetus; after birth, the children will have premature closure of fontanelles, widening and protruding jawbones, forward tilt of the nose, and narrowing of the aorta, which is not conducive to the growth and development of the child and damages the appearance of the offspring. Generally speaking, pregnant women need 800 mg of calcium per day in the early stages of pregnancy, which can be increased to 1,100 mg in the later stages. This does not require special supplements, as long as they are reasonably absorbed from daily dairy products, fish, meat, eggs and other foods.

　　5. It is not advisable to eat too much salty food: Some pregnant women are fond of salty food due to their eating habits, especially those in northern China. Modern medical research believes that there is a certain relationship between the amount of salt consumed and the incidence of hypertension. The more salt consumed, the higher the incidence. As we all know, pregnancy-induced hypertension is a disease unique to pregnant women. Its main symptoms are edema, high blood pressure and proteinuria. In severe cases, it may be accompanied by subjective symptoms such as headache, dizziness, chest tightness, dizziness, and even eclampsia, which endangers the health of the mother and baby. Pregnant women eating too much salty food can easily cause pregnancy-induced hypertension syndrome. Therefore, Beijing Tianlun Infertility Hospital pregnancy experts recommend that pregnant women should consume about 6 grams of salt per day.

　　6. It is not advisable to have an acidic diet: Pregnant women may have picky eaters, loss of appetite, nausea, vomiting and other early pregnancy symptoms in the early stages of pregnancy. Many people are addicted to an acidic diet. However, relevant scientists from the Federal Republic of Germany have found that if the mother ingests a large amount of acidic drugs or other acidic substances in early pregnancy, it may affect the normal division, proliferation and development of embryonic cells, and may easily induce mutations in genetic material, leading to fetal malformations. As the fetus matures, the pH in its tissue cells gradually approaches that of the mother, and the degree of impact will gradually decrease. Therefore, pregnant women should not use acidic drugs or acidic diet in the early stages of pregnancy.

　　7. It is not advisable to take excessive warming supplements: Pregnant women have significantly increased blood flow in the blood circulation system, which increases the burden on the heart. The blood vessels in the cervix, vaginal wall, fallopian tube and other parts of the body are also in a state of expansion and congestion. In addition, pregnant women have strong endocrine function and increase the secretion of aldosterone, which can easily lead to water and sodium retention, resulting in edema, hypertension and other diseases. Furthermore, pregnant women may suffer from loss of appetite, gastric bloating, constipation and other phenomena due to reduced gastric acid secretion and weakened gastrointestinal function. In this case, if pregnant women often take warm tonics and supplements, such as ginseng, velvet antler, deer fetal gum, antler gum, longan, lychee, walnut meat, etc., it will inevitably lead to yin deficiency and yang hyperactivity, qi imbalance, qi excess and yin depletion, blood heat, aggravate symptoms such as morning sickness, edema, high blood pressure, constipation, and even cause miscarriage or stillbirth.

　　8. It is not advisable to eat moldy food: When pregnant women eat agricultural and sideline products and food contaminated with mycotoxins, not only will acute or chronic food poisoning occur, but it may even affect the fetus. Because in the early 2-3 months of pregnancy, the embryo is implanting and developing, and the embryonic body cells are in a highly proliferative and differentiated stage. Mycotoxin damage can cause chromosome breakage or aberration, leading to hereditary diseases or fetal malformations, such as congenital heart disease, congenital malignancy, etc. Some even cause the fetus to stop developing and cause stillbirth or miscarriage. On the other hand, in the middle and late stages of pregnancy, because the functions of the fetal organs are not yet perfect, especially the functions of the liver and kidneys, mycotoxins can also have toxic effects on the fetus. A large amount of medical research data confirms that mycotoxin is a strong carcinogen that can cause liver cancer and gastric cancer in mothers and fetuses.
