What should you pay attention to when preparing for pregnancy?

Pregnancy is a very difficult thing. Pregnant women should

1. Crab: It tastes delicious, but it is cold in nature and has the function of promoting blood circulation and removing blood stasis, so it is not good for pregnant women, especially crab claws, which have obvious abortion effects. 2. Soft-shelled turtle: Although it has the effect of nourishing yin and benefiting the kidney, the nature of soft-shelled turtle is salty and cold, and it has a strong effect of clearing blood vessels and dispersing blood stasis, so it has certain disadvantages of causing abortion, especially the abortion effect of turtle shell is stronger than that of turtle meat. 3. Job's tears: It is a food and medicine, and Chinese medicine believes that it has a smooth and slippery texture. Pharmacological experiments have shown that coix seed has an excitatory effect on uterine smooth muscle, which can promote uterine contraction and thus may induce miscarriage. 4. Purslane: It is both a herb and a vegetable, and its medicinal properties are cold and slippery. Experiments have shown that purslane juice has a significant stimulating effect on the uterus, which can increase the frequency and intensity of uterine contractions, and can easily cause miscarriage. Foods that are harmful to the fetus

5. Canned Food

A certain amount of additives are added to canned foods during the production process, such as artificial synthetic colors, flavors, preservatives, etc. Although these additives have little effect on healthy adults, excessive intake of them by pregnant women is harmful to their health. In addition, the nutritional value of canned food is not high. After high-temperature processing, the vitamins and other nutrients in the food have been destroyed to a certain extent. 6. Spinach

People have always believed that spinach is rich in iron and has the function of replenishing blood, so it is regarded as a good vegetable for preventing 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 decreases, affecting the growth and development of the fetus. 7. Chocolate and hawthorn: Eating too much chocolate will make pregnant women feel full, thus affecting their appetite. As a result, they gain weight while lacking necessary nutrients. Pregnant women prefer to eat sour things, so hawthorn becomes the fruit of choice. Hawthorn has a stimulating effect on the uterus. If pregnant women eat too much, it may cause uterine contraction and lead to miscarriage, so they should eat less. 8. Pork liver: Finland and the United States advise pregnant women to eat less pork liver. This is because modern feed used to fatten livestock quickly contains too many fattening agents, which are high in vitamin A and cause it to accumulate in large quantities in the animal's liver. If pregnant women eat too much pork liver, a large amount of vitamin A will easily enter the body, which will cause great harm to the development of the fetus and may even cause malformations. 9. Potatoes that have been stored for a long time contain biota. The longer the potatoes are stored, the higher the biota content. Eating too much of this kind of potato can affect the normal development of the fetus and cause fetal malformations. Of course, people vary greatly from person to person, and not everyone will experience abnormalities after eating it, but it is better for pregnant women not to eat it, especially potatoes that have been stored for a long time. 10. Hot condiments Pregnant women should eat hot condiments such as fennel, star anise, prickly ash, pepper, cinnamon, five-spice powder, etc., which can easily consume intestinal moisture, reduce gastrointestinal secretion, and cause intestinal dryness and constipation. After constipation occurs, pregnant women will inevitably hold their breath and forcefully defecate, which increases abdominal pressure and compresses the fetus in the uterus, easily causing adverse consequences such as fetal movement disorder and premature birth. 11. MSG The main ingredient of MSG is monosodium glutamate, which combines with zinc in the blood and is excreted from the urine. Excessive intake of MSG will consume a large amount of zinc, leading to zinc deficiency in pregnant women. Zinc is essential for fetal growth and development, so pregnant women should eat less. 12. Longan and lychee: They are warm in nature and can easily cause fetal fever; 13. Pomegranate: People with anemia should eat less; 14. Pickled sauerkraut: They contain nitrosamines, which can cause fetal deformities. 15. Watermelon: You should not eat more than 250g of fruit per day. Limit the amount of watermelon you eat because watermelon is a diuretic and can easily cause dehydration in pregnant women. 16. Drink strong tea. A British doctor found that tea contains a lot of fluoride. The fluoride content in a cup of strong tea can reach 1.25 mg. If used to feed pregnant mice, the mice born were found to have skeletal deformities. Although the harm of fluoride to the fetus has not yet been confirmed, it is still better not to drink strong tea. Drinking strong tea during pregnancy is not only prone to iron deficiency anemia, which affects the nutrient supply to the fetus, but also because strong tea contains caffeine, it will increase the heart rate and urination rate of pregnant women, increase the burden on the heart and kidneys of pregnant women, and damage the health of the mother and fetus. 17. Drinking coffee and cola-type beverages. The main ingredients of coffee and cola are caffeine, clonidine and other alkaloids.

Caffeine and clonidine are drugs that stimulate the central nervous system. According to measurements, a 340-gram bottle of cola-type beverage contains 50 to 80 mg of caffeine. If a caffeine beverage containing more than 1 gram is consumed at one time, it will lead to excitement of the central nervous system, manifested as restlessness, rapid breathing, muscle tremors, tachycardia, premature contractions, insomnia, dizziness, tinnitus, etc. Even if you take less than 1 gram, irritation to the gastric mucosa can cause poisoning symptoms such as nausea, vomiting, dizziness, palpitations, and precordial pain. The fetus is particularly sensitive to caffeine, which can quickly pass through the placenta and act on the fetus, causing adverse effects on the fetus. Experiments on injecting caffeine into pregnant mice have confirmed that the offspring are more likely to suffer from cleft palate, meningocele, spina bifida, loss of mandible, loss of eyes, skeletal abnormalities, dwarfism, and limb deformities. For the health of the next generation, pregnant women should drink coffee and cola drinks with caution or avoid them. 18. Alcohol consumption during pregnancy is an important cause of fetal malformation and mental retardation.

. This is because any trace amount of alcohol can pass through the placenta unimpeded and enter the fetus, making the alcohol concentration in the fetus the same as that in the mother. A French medical doctor once observed 127 children born to women with alcohol addiction and found that they all had common defects: single eyelids, even double eyelids were not obvious, flat nose, everted eyelids at the inner corners of the eyes, flat and narrow face, blurred nasal grooves, thin and tight upper lips, and short chins. Children who are poisoned by alcohol and have incomplete facial development account for about one-third of the children born to drinking mothers. Even more serious is the harm that alcohol does to the brain and heart. About 30% of babies born to pregnant women who drink alcohol will suffer from heart disease. It is not uncommon for pregnant women who drink too much to give birth to babies who die shortly afterwards. The autopsy results of the dead babies showed that their brains were not only smaller than those of normal babies, but also underdeveloped or obviously deformed. Many countries have conducted intelligence tests on children who were exposed to alcohol during their fetal period and found that their IQs were below average, with most of them showing symptoms of slow reaction, mental retardation or idiocy.
