In recent years, foreign studies have pointed out that acidic foods and drugs are one of the culprits leading to teratogenesis. The researchers measured the pH values of fetal tissues and maternal blood in different periods, and concluded that it is best not to eat or eat less acidic foods or drugs (such as vitamin C and aspirin) in the first half of pregnancy. Because a large number of acidic foods will reduce the alkalinity in the body and easily cause fatigue and weakness. Long-term acidic constitution is not only easy to make the mother suffer from some diseases, but more importantly, it will affect the normal and healthy growth and development of the fetus, and even lead to fetal malformation. Therefore, pregnant women should not eat too much acidic food.
Pregnant women should not eat warm supplements. Due to the obvious increase of blood flow in the whole blood circulation system, the burden on the heart is increased, and the blood vessels of the cervix, vaginal wall and fallopian tube are also in a state of dilatation and congestion. In addition, the endocrine function of pregnant women is strong, and the secretion of aldosterol increases, which is easy to lead to water and sodium retention, edema, hypertension and other diseases. Furthermore, due to the decrease of gastric acid secretion, the gastrointestinal function of pregnant women is weakened, and there will be symptoms such as anorexia, flatulence and constipation. In this case, if pregnant women often take warming tonics, such as ginseng, velvet antler, deer fetal glue, antler glue, longan, litchi, walnut kernel and so on. It will inevitably lead to yin deficiency and hyperactivity of yang, disorder of trapped qi, excessive consumption of qi and yin, rash caused by blood heat, aggravation of morning sickness, edema, hypertension, constipation and other symptoms, and even miscarriage or stillbirth.
What foods can't pregnant women eat? 1. Avoid eating crabs, kelp and soft-shelled turtles: eating them will cause early pregnancy bleeding and abortion.
2, do not eat rice kernels and horse teeth: rice kernels, also known as coix seed, promote uterine contraction and easily induce abortion. Horse teeth can also increase uterine contraction, increase strength, and easily cause miscarriage.
3, do not eat apricots and almonds: the hot and slippery characteristics of apricots are taboo for pregnant women. Almonds contain highly toxic substances. Children will die if they eat 7~ 10 almonds, so pregnant women should fast.
4, do not eat black fungus: because it has the effect of promoting blood circulation and removing blood stasis, it is not conducive to the stability and growth of embryos, so do not eat.
5, do not eat hawthorn: hawthorn has the effect of contracting the uterus, not edible.
6, canned food: Because it contains additives, pregnant women eat too much, which will be bad for the baby.
7. Cold drinks and soda: After pregnancy, women's gastrointestinal function is weakened. Too cold food will cause gastrointestinal blood vessels to contract suddenly, weaken digestive function, and have symptoms such as diarrhea and abdominal pain. Soda will consume the iron in the expectant mother's body, leading to anemia and affecting the baby's development.
8. Spinach: The oxalic acid in spinach affects the body's absorption of calcium and zinc. Excessive intake by expectant mothers will reduce the content of calcium and zinc in the body and affect the baby's growth and development.
