The dietary nutrition of pregnant women is not only related to their own physiological needs, but also related to the development of the fetus. In addition to enhancing the necessary nutrition, pregnant women should also avoid the following foods.
1, avoid excessive consumption of salty food and fast salted fish;
Pregnant women often eat salty food, which will lead to sodium retention in the body, cause edema and affect fetal development.
2. Avoid drinking and smoking:
Drinking alcohol in pregnant women will lead to fetal malformation and cause fetal alcoholism syndrome. The smoke produced by cigarettes contains hundreds of harmful substances. After pregnant women smoke or smoke passively, the harmful substances inhaled will affect the normal development of the fetus, which will seriously lead to fetal malformation.
3. Avoid eating fruits and vegetables contaminated by pesticides:
Toxic pesticides such as organophosphorus, organochlorine and organomercury. After pregnant women eat contaminated fruits and vegetables, it will lead to the normal control process of genes turning or fetal growth retardation, which will lead to fetal development stop, abortion and premature delivery.
4, avoid eating a lot of flavors and pigments, peppers, mustard, curry, spicy food.
5. It is not advisable to eat too many peaches.
Peaches are sweet, hot and bitter, and contain vitamins A, B and C, but peaches are easy to attract insects. "Compendium of Materia Medica" says that eating too many raw peaches makes people bloated, and treating carbuncle is harmful and useless, so it is second only to fruit.
6, pregnant women avoid drinking coffee and strong tea:
Coffee can refresh the mind, and the fetus is particularly sensitive to caffeine, which can quickly act on the fetus through the placenta. If pregnant women drink too much coffee and cola drinks, the fetus will be directly affected by caffeine. Caffeine has side effects. Excessive caffeine intake will stimulate fetal movement, affect fetal bone development, induce fetal malformation and even lead to stillbirth.
Strong tea contains more caffeine, about 0.06mg per 500ml of strong tea water. Tea contains a lot of tannic acid, which can combine with iron in food to form compounds that cannot be absorbed by human body, increasing the possibility of anemia in pregnancy. Excessive intake of caffeine and anemia by pregnant women will affect the intellectual development of babies.
7, pregnant women avoid drinking soda:
There are many carbonates in soda water, which can react with iron in food after entering the intestine, reducing the absorption and utilization of iron by human body. Pregnant women and fetuses need more iron than ordinary people. Drinking too much soda will cause iron deficiency in human body and cause iron deficiency anemia. In addition, soda contains more sodium, which will aggravate the edema of pregnant women.
8. Longan is not suitable for overeating.
Longan is also known as longan. Because of its heat, it is not suitable for people with yin deficiency and internal heat constitution. After pregnancy, most of the yin and blood are deficient in heat, and yin deficiency leads to internal heat, so symptoms such as dry mouth and dry stool often appear. Pregnant women eat a lot, not only can not protect the fetus, but sometimes there will be symptoms of threatened abortion (abdominal pain, vaginal bleeding). If you want to eat, you can scald it with boiling water and eat a little at a time.
9. Avoid eating big fish:
The US Food and Drug Administration advises pregnant women not to eat swordfish, sharks, mackerel and other large fish, and the canned seafood tuna should not exceed180g. The law of ecology tells us that every time the trophic level is raised, the pollutants that are difficult to decompose will be concentrated several times or even dozens of times. For example, the concentration of a pollutant in water is one in one hundred thousand, and it will be concentrated to more than one in ten thousand when it reaches algae; Small fish eat algae for a living, and it will continue to focus on pollution; Eat small fish, a big fish, can swallow the pollutants accumulated by small fish for several months in one bite. Pregnant women, nursing mothers and young children should try not to choose canned fish, and it is advisable not to do it more than once a month. If pregnant women often eat canned food made of contaminated fish, mercury can be transmitted to fetuses and babies through placenta and milk, thus affecting children's brain nerve development and intellectual development. In contrast, salmon and yellow croaker are safer.
10, avoid eating raw meat and undercooked meat:
Don't eat raw or undercooked poultry and seafood (such as oysters, clams and sushi). They may contain a lot of bacteria and viruses and can only be eaten after being cooked. In addition, don't eat the eggs half-baked, but fry them well. There are microorganisms and other germs in eggs, which can only be completely killed if they are cooked at 100℃ for more than 5 minutes.
1 1. Avoid eating cooked food and cold smoked seafood bought outside;
Listeria is most likely to breed in cooked food, such as hot dogs, ham, turkey, cold meat sauce and sausages, as well as refrigerated smoked seafood. Pregnant women infected with this bacteria will lead to serious consequences such as abortion, deformity or stillbirth. These products must be cooked before they can be eaten.
12, avoid eating hawthorn
Hawthorn is sweet and sour, and many pregnant women like it. However, hawthorn has a certain exciting effect on the uterus, which can promote uterine contraction and even lead to abortion.
13, avoid eating coix seed and purslane;
Coix seed, also known as Coix seed, is a kind of plant seed that can be used as medicine and eaten blindly. Rich in nutrition, sweet and cool in taste, and has the functions of invigorating spleen, tonifying lung, clearing away heat and promoting diuresis. But Chinese medicine believes that it is slippery. Pharmacological experiments show that it can excite uterine smooth muscle and make uterus contract, so it may induce abortion. Portulaca oleracea, also known as Portulaca oleracea and zucchini, is a kind of wild vegetable, which has been cultivated by people. It has high nutritional value, can be used as medicine, and has a strong inhibitory effect on Escherichia coli, Shigella and typhoid. It is both herbal medicine and edible, but it is cold and slippery. Experiments show that Portulaca oleracea juice has obvious exciting effect on uterus, which can increase the number and intensity of uterine contractions and easily cause abortion.
14, to avoid potato germination:
Potatoes contain a toxin called Solanum nigrum, which is concentrated in the parts that germinate, turn green and fester. Solanum nigrum has hemolytic effect after being absorbed into the blood, and can also paralyze the motor and respiratory center and stimulate the gastric mucosa. Eventually, he will die of respiratory center paralysis. If pregnant women eat a lot of potatoes with high alkaloid content for a long time, the accumulation in the body will cause fetal malformation. Moreover, the alkaloids in potatoes can not be reduced by conventional cooking methods such as soaking, steaming and boiling. Therefore, pregnant women had better not eat or eat less potatoes. Or add vinegar when cooking.
15, avoid eating aloe:
Aloe juice can cause pelvic bleeding and even abortion; The ingredients of aloe vera mixed with milk can irritate children and cause diarrhea.
16, should not eat fried food:
The cooking oil of foods that are repeatedly heated, boiled and fried may contain carcinogens.
Pregnant women can't eat fritters. Because a certain amount of alum will be added to the fried dough sticks when they are made, and alum is an aluminum compound. When deep-fried dough sticks are used, 15g alum is generally needed for every 500g flour. If a pregnant woman eats two fried dough sticks every day, she will eat almost 3 grams of alum, and the accumulated intake will be quite amazing. Aluminum can enter the fetal brain through the placenta, which makes the brain develop slowly, thus increasing the incidence of dementia in children.
17, safflower oil:
Avoid using.
18, excessive consumption of cold food:
Although prenatal cold tonic is needed, it refers to the coolness of food, not raw or cold food; Cold food, such as sashimi and lettuce, is easy to cause diarrhea because it has not been disinfected; Iced food and drinks will affect the development of fetal trachea and easily give birth to allergic children.
19, leek, malt (sugar):
It is very effective to milk after delivery, but it will affect the secretion of hormones in pregnant women and easily cause nausea and vomiting.
20, bitter gourd:
Bitter gourd contains quinine, which stimulates uterine contraction and leads to abortion. However, the content of bitter gourd is very small, so it is not serious for pregnant women to eat it in moderation, but for the sake of prudence, pregnant women with threatened abortion and habitual abortion in the first trimester should eat less.
2 1, other taboo foods include ginseng, velvet antler, deer fetus and other nourishing Chinese medicines.
