Although turtle has the effect of nourishing yin and benefiting the kidneys, turtle is salty and cold in nature, with strong blood circulation and dissipate stasis, so there is a certain abortion, especially the abortive power of turtle armor is stronger than turtle meat. Job’s tears are a kind of medicine and food, 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, which can promote uterine contraction, thus inducing the possibility of abortion. It is both herbal medicine and can be used as a dish to eat, its medicinal properties cold and slippery. Experiments have proved that amaranth juice has obvious excitatory effect on the uterus, which can make the uterus contract more often and increase the intensity, and easily cause miscarriage. Canned foods are made with a certain amount of additives, such as synthetic colors, flavors, and preservatives. Although these additives have little effect on healthy adults, pregnant women who eat too much is not good for their health. In addition, the nutritional value of canned food is not high, after high-temperature processing, the vitamins and other nutrients in food have been damaged to a certain extent. People have always thought that spinach is rich in iron, has the function of blood, so it is taken as a good vegetable to prevent anemia during pregnancy. In fact, spinach does not contain much iron, but contains a lot of oxalic acid. Oxalic acid can affect the absorption of zinc and calcium. The calcium and zinc content in pregnant women’s bodies decreases, affecting the growth and development of the fetus. Excessive consumption of chocolate will make pregnant women feel full, thus affecting the appetite, the result is that the body fat, while the essential nutrients are lacking. Pregnant women prefer to eat sour things, hawthorn becomes the preferred fruit. Hawthorn to the uterus has an exciting effect, pregnant women over-eating can make the uterus contraction, leading to the possibility of miscarriage, so eat less. Finland and the United States have put forward to the pregnant women should eat less pig liver advice. Because in the modern feed for livestock rapid fattening, added too much fattening agent, which vitamin A content is very high, resulting in it in the animal liver in a large number of accumulation. 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 even lead to malformation. Potatoes contain alkaloids, and the longer the potatoes are stored, the higher the alkaloid content. Excessive consumption of such potatoes can affect the normal development of the fetus, resulting in fetal malformation. Of course, there are great individual differences, not everyone will have abnormalities after consumption, but pregnant women still do not eat, especially do not eat long-term storage of potatoes. Pregnant women who eat hot ingredients such as cumin will be constipated if they eat them at the same time. When constipation occurs, pregnant women must hold their breath to relieve themselves, which increases the abdominal pressure and compresses the fetus in the uterus, easily resulting in fetal restlessness, premature labor and other negative consequences. The main component of MSG is monosodium glutamate, zinc in the blood and its combination will be excreted from the urine, excessive intake of MSG will consume a large amount of zinc, resulting in a lack of zinc in pregnant women. Zinc is essential for fetal growth and development, so pregnant women should eat less. Cinnamon, lychee is warm and hot, easy to cause fetal fever; pomegranate anemia should be eaten sparingly. Pickled sauerkraut contains nitrosamines, which can lead to fetal malformation. Should not eat more than 250g of fruit a day, limited to watermelon, because watermelon is a diuretic, easy to cause dehydration in pregnant women. A British doctor found that tea contains a lot of fluoride components, a cup of strong tea fluoride content of up to 1.25 mg. If used to feed pregnant mice, it was found that the mice born with bone deformities, fluoride on the fetus, although not yet sure, 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, increasing the burden on the pregnant woman’s heart and kidneys, which is detrimental to the health of the mother and the fetus. The main components of coffee and cola are caffeine, colanine and other alkaloids. Caffeine and colanine are drugs that stimulate the central nervous system. It has been determined that a bottle of 340 grams of cola-type drinks contains 50 to 80 mg of caffeine, and if you drink more than 1 gram of caffeine at a time, it will lead to excitation of the central nervous system, which manifests itself as restlessness, accelerated respiration, muscle tremor, tachycardia, extra-periodic contractions, and insomnia, dizziness, 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 drink coffee and cola-type beverages with caution or ban them. Studies have shown that alcohol consumption by pregnant women is a major cause of malformations and mental retardation in babies. This is because any trace of alcohol can pass through the placenta and enter the fetus without any obstruction, making the concentration of alcohol in the fetus the same as that in the mother’s body. 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 infants 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 been alcohol poisoning in the fetal period of the child intelligence test, found that their IQ is lower than the general level, most of the performance for the slow reaction, mental retardation or idiocy.
