Chinese medicine that its quality slippery. Pharmacological experiments have proved that Job’s tears have an excitatory effect on the smooth muscle of the uterus, can promote uterine contraction, thus inducing the possibility of miscarriage; 4, Amaranthus: it is both herbal medicine and can be eaten as a dish, and its medicinal properties are cold and slippery. Experimental evidence, amaranth juice for the uterus has a significant role in excitation, can make the uterus contraction increased, increased intensity, easy to cause miscarriage. 5, canned food Canned food in the production process are added to a certain amount of additives, such as synthetic colors, flavors, preservatives and so on. Although these additives have little effect on healthy adults, but pregnant women eat too much is not good for health. In addition, the nutritional value of canned food is not high, after high-temperature processing, food vitamins and other nutrients have been damaged to a certain extent. 6, spinach people have always thought that spinach is rich in iron, has the function of blood, so it is used as a good vegetable to prevent anemia during pregnancy. In fact, spinach is not much iron, but contains a lot of oxalic acid. Oxalic acid can affect the absorption of zinc and calcium.

Pregnant women over-eating pig liver, a large number of vitamin A will easily enter the body, the development of the fetus is very harmful, and will even cause malformation. 9, long storage of potatoes Potatoes contain alkaloids, the longer the storage of potatoes alkaloids content is higher. Excessive consumption of such potatoes can affect the normal development of the fetus, resulting in fetal malformation. Of course, the individual differences are great, not everyone will be abnormal after eating, but pregnant women still do not eat good, especially do not eat long-term storage of potatoes. 10, hot ingredients Pregnant women eat hot ingredients cumin, anise, pepper, pepper, cinnamon, five spice powder and other easy to consume intestinal water, so that gastrointestinal secretion is reduced, resulting in intestinal dryness, constipation. After constipation, pregnant women are bound to use force to hold their breath to relieve defecation, increasing abdominal pressure, oppression of the fetus in the uterus, easy to cause fetal restlessness, preterm labor and other adverse consequences. 11, monosodium glutamate MSG is the main component of monosodium glutamate, zinc and its combination in the blood will be discharged from the urine, excessive intake of monosodium glutamate will consume a large amount of zinc, resulting in a lack of zinc in pregnant women.

If used to feed pregnant mice, it was found that the mice born with bone deformities, fluoride on the fetus, although the harm is not yet certain, but still do not drink strong tea as well. Drinking strong tea during pregnancy is not only prone to iron deficiency anemia, affecting the supply of nutrients to the fetus, because strong tea contains caffeine, but also increase the heartbeat of pregnant women and the number of times of urination, increase the burden on the pregnant woman’s heart and kidneys, and damage the health of the mother and fetus. 17, drinking coffee and cola-type drinks Coffee and cola are mainly composed of caffeine, colanine and other alkaloids. Caffeine and colanine are drugs that excite the central nervous system. It has been determined that a bottle of 340 grams of cola-type drinks contain 50 to 80 mg of caffeine, and if you drink more than 1 gram of caffeinated beverages at a time, it will lead to excitation of the central nervous system, manifesting itself as restlessness, accelerated respiration, muscular tremor, tachycardia, extra-periodic contractions, and insomnia, blurred vision, ringing in the ears, and so on. Even if you take less than 1 gram, due to the stimulation of the gastric mucosa, nausea, vomiting, dizziness, palpitations and precordial pain and other symptoms of poisoning. Fetus is particularly sensitive to caffeine, caffeine can quickly pass through the placenta and act on the fetus, so that the fetus is adversely affected. Some pregnant rats injected with caffeine experiments have confirmed that the rats are prone to cleft palate, meningoencephalocele, spina bifida, no jaw, no eyes, skeletal anomalies, dwarfism, limb deformities and other phenomena. For the health of the next generation, pregnant women should be cautious or prohibited from drinking coffee and cola-type drinks. 18, drinking alcohol Research shows that pregnant women drinking alcohol is an important cause of infant malformation and mental retardation. This is because any trace of alcohol can pass through the placenta and enter the body of the fetus without any obstruction, so that the concentration of alcohol in the fetus and the concentration of alcohol in the mother’s body is the same. French medical doctors have 127 women with drinking addiction to the children born of observation, found that they have common defects: single eyelids, even double eyelids are not obvious, flat nose, inner corner of the eye eyelids outwardly turned, flat and narrow face, nasal grooves fuzzy, thin and tight upper lip, short chin. This kind of children poisoned by alcohol, facial development is not sound about 1/3 of the children born to drinking mothers. more serious is the harm of alcohol on the brain and heart, pregnant women drinking alcohol leads to babies suffering from heart disease accounted for about 30%. It is not uncommon for babies born to pregnant women who have consumed too much alcohol to die soon after birth. The autopsy results of dead babies show that their brains are not only smaller than normal children, but also have incomplete brain development or obvious deformities. Many countries have conducted intelligence tests on children who were poisoned by alcohol during their fetal life, and found that their IQs were below the general level, and most of them showed slow reaction, mental retardation or idiocy.
