Therefore, it is recommended to eat foods rich in folic acid. Folic acid is found in animal livers, egg yolks, green vegetables such as spinach and beans, and celery. Folic acid needs to be added before conception and during the early stages of pregnancy, as this is when the embryo is forming.
2. Avoid high-fat foods
Although fat itself is not carcinogenic, long-term consumption of high-fat foods will increase the concentration of bile acid and neutral cholesterol in the large intestine. If pregnant women eat a high-fat diet for a long time, the 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 are harmful to the health of mothers and infants.
3. Avoid high-calcium diet
If you drink a lot of milk, take calcium tablets and vitamin D, etc., it will be harmful to the fetus. Excessive calcium supplementation in pregnant women may cause fetal hypercalcemia. After birth, the mastoid process will close prematurely and the jaws will become wider and protruding, which is not conducive to healthy growth and development.
IV. Caution is needed in supplementation
Pregnant women often take warming supplements, such as ginseng and velvet antler, etc., which will inevitably lead to yin deficiency and yang hyperactivity, qi and yin depletion, blood-heat delusions, and aggravate pregnancy. Vomiting and edema can lead to symptoms such as high blood pressure, constipation, and even miscarriage in severe cases.
5. Avoid eating cold food
Some women like to drink cold food, because eating cold food after pregnancy is harmful to health. The gastrointestinal tract of pregnant women during pregnancy is extremely sensitive to hot and cold stimulation. Eating too much cold food can cause gastrointestinal blood vessels to suddenly contract, gastric juice secretion to decrease, and digestive function to decline, leading to loss of appetite, indigestion, diarrhea, and even stomach cramps, causing severe abdominal pain.
6. Avoid eating high-sugar foods
If pregnant women eat more high-sugar foods during pregnancy, not only will they have high blood sugar, but they will also cause the fetus to be overweight during delivery. On the other hand, high blood sugar will increase the burden on the kidneys of pregnant women and is not conducive to health care during pregnancy.
7. Avoid smoking and drinking
Pregnant women who smoke in the first three months of pregnancy may increase the chance of their babies suffering from cleft palate or cleft palate. If you smoke or regularly inhale secondhand smoke during pregnancy, your baby will have learning disabilities or behavioral problems in the future. Alcohol can also cause serious damage to fetal brain development. So cigarettes and alcohol must be eliminated.
