1. Tea Drinking Should Be in Moderation: Pregnant women should avoid drinking excessive or overly concentrated tea, as theobromine (caffeine) in tea has stimulating effects that may increase fetal movement and even harm fetal growth and development.
2. Soft Drinks Should Be in Moderation: As some drinks contain 2.4%-2.6% caffeine, colamine and other bio-alkaloids, pregnant women who drink them may experience nausea, vomiting, headache, rapid heartbeat and other poisoning symptoms, affecting the normal development of important organs such as the fetal brain, heart and liver, leading to congenital diseases in newborns.
3. Vinegar Intake Should Be Controlled: Excessive vinegar and acidic foods are one of the main causes of fetal malformations. Especially during the first half month of pregnancy, large amounts of acidic foods can reduce the body's alkalinity, causing fatigue and weakness. Long-term acidity not only makes the mother susceptible to certain diseases but also affects the normal growth and development of the fetus, even leading to fetal malformations.
4. Alcohol Should Be Avoided: Since alcohol contains ethanol which is toxic to the human brain, liver and heart. It can pass through the placenta into the fetus, causing intellectual disability, special facial features, and short stature in infants after birth, severely leading to intellectual disabilities.
5. Hawthorn Intake Should Be Controlled: Modern medical research has confirmed that hawthorn has a contracting effect on the female uterus. If pregnant women consume large amounts of hawthorn and its products, it will stimulate uterine contractions, seriously leading to miscarriage.
6. Hot Spices Should Be Avoided: Eating hot spices such as fennel, star anise, Sichuan pepper, cinnamon, chili, five-spice powder, fried or roasted hot foods after pregnancy can easily deplete intestinal water, reducing secretion from the gastrointestinal glands and causing constipation. Constipation can cause pregnant women to strain during bowel movements, increasing abdominal pressure, pressing on the fetus within the uterus, easily leading to fetal restlessness, fetal malformations, premature rupture of membranes, spontaneous abortion, and preterm birth.
7. Fried Dough Sticks Intake Should Be Controlled: Fried dough sticks contain a certain amount of alum, which is an organic compound containing aluminum. Aluminum can penetrate the placenta into the fetal brain, causing brain disorders and increasing the incidence of dementia.
8. Medication Should Be Controlled: During weeks 3 to 3 months of pregnancy, it is the period when embryonic organs form, making the fetus highly sensitive to medication. Clinical surveys have confirmed that certain drugs can lead to fetal malformations, commonly including prednisone, streptomycin, aspirin, meprobamate (tranquilizer), diazepam, tetracycline, chloramphenicol, long-acting sulfonamides, etc. If pregnant women must take medication, it should be under the guidance of a specialist doctor.
9. Contact with Detergents Should Be Controlled: Chemical components in detergents such as linear alkyl iodate and alcohol can destroy and lead to denaturation and necrosis of fertilized eggs. Especially during early pregnancy after a new marriage, if various detergents (laundry detergent, shampoo, dish soap, etc.) are excessively contacted, these chemical components will be absorbed by the skin and accumulate in the body, causing outer layer cell denaturation of fertilized eggs, leading to miscarriage.
