Ten dietary taboos that pregnant women must know

　　Not suitable for high-fat diet

　　A large amount of medical research data confirms that breast cancer、ovarian cancer and cervical cancer There is a family genetic tendency. If a pregnant woman eats a high-fat diet for a long time, the risk of her daughter suffering from 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 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, promote the occurrence of breast cancer, and are detrimental to mothers and infants. healthy。

　　Not suitable for high calcium diet

　　Pregnant concubines blindly follow a high-calcium diet, drink a lot of milk, and take calcium tablets, vitamin D, etc., which are harmful to fetus Harmful rather than helpful. Nutritionists believe that excessive calcium supplementation in pregnant women may cause hypercalcemia in the fetus. After birth, the children will have premature closure of the fontanelles, widening and protruding jawbones, anteversion of the spine, and narrowing of the aorta. This is not only detrimental to healthy growth and development, but also harmful to 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 consumed from daily fish, meat, eggs and other foods.

　　Don’t eat too much salty food

　　Some pregnant women are fond of salty food due to their eating habits, especially northern residents who tend to eat 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 a person consumes, the higher the incidence of hypertension. As we all know, pregnancy-induced hypertension syndrome It is a special disease that only occurs in women during pregnancy. disease , 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, etc., and may even cause eclampsia, endangering the health of the mother and baby. Therefore, pregnant women who eat too much salty foods can easily cause pregnancy-induced hypertension syndrome. For health care during pregnancy, experts recommend that the daily salt intake should be about 6 grams.

　　Not suitable for acidic diet

　　Pregnancy tears can cause early pregnancy symptoms such as food selection, loss of appetite, nausea, and vomiting in the early stages of pregnancy. Many people are fond of acidic diets. However, relevant scientists from the Federal Republic of Germany have found that the acidity of fetuses in early pregnancy is low. Acidic drugs or other acidic substances ingested by the mother can easily accumulate in fetal tissues in large quantities, affecting the normal division, proliferation and development of embryonic cells, and can easily induce mutations in genetic material, leading to abnormal fetal development. In the later stages of pregnancy, as the fetus becomes increasingly mature, the pH in its tissue cells is close to that of the mother, so the harmful effects are accordingly smaller. Therefore, pregnant women should not take acidic drugs, acidic foods, acidic drinks, etc. during the first 2 weeks of pregnancy.

　　It is not advisable to take excessive amounts of warming supplements

　　Because the blood flow in the blood circulation system of pregnant women increases significantly, the burden on the heart increases. Uterus The blood vessels in the neck, vaginal wall, fallopian tube and other parts of the body are also in a state of expansion and congestion. In addition, the endocrine function of pregnant women is strong and the secretion of aldosterol increases, which can easily lead to water and sodium retention and cause edema, hypertension and other diseases. Furthermore, pregnant women may suffer from loss of appetite and gastric bloating due to reduced gastric acid secretion and weakened gastrointestinal function. constipate and other phenomena. In this case, if pregnant women often take warm tonics and supplements, such as ginseng, velvet antler, deer fetal gum, deer antler gum, longan, lychee, walnut meat, etc., it will inevitably lead to yin deficiency and yang hyperactivity, trapped qi and imbalance, excessive qi and yin consumption, blood and heat, exacerbating symptoms such as morning sickness, edema, high blood pressure, constipation, and even miscarriage or stillbirth.
