When it comes to spinach, people often think that it has a high iron content! Actually, this is a misunderstanding! Now scientists have found in their calculations that the decimal point of iron content is wrong from the beginning! When it comes to eating less spinach, everyone will be a little surprised. Spinach is rich in iron, which can replenish blood, and is also rich in vitamin C and other nutrients. Why should you eat less when you are pregnant? Studies have shown that spinach contains a lot of oxalic acid, which is harmful to trace elements such as zinc and calcium. Calcium and zinc are indispensable minerals for human body. If it is destroyed by oxalic acid, it will make pregnant women lack calcium and zinc. Once a child is short of calcium, rickets, chicken breasts, bowlegs, and tooth growth retardation will occur. Therefore, excessive consumption of spinach by pregnant women is undoubtedly unfavorable to fetal development. Usually, when you need to supplement calcium-containing foods or vegetables that often contain oxalic acid, blanch them with water. Celery is edible! ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Pregnant women can often eat all kinds of vegetables in their daily diet.

Fourth, wild vegetables Wild vegetables are another good nutrition for pregnant women. Wild vegetables are not only better than garden vegetables because of less pollution or no pollution, but also have dual functions of nutrition and diet therapy. Chinese nutritionists have analyzed nearly 100 kinds of edible wild vegetables in China, and found that wild vegetables are rich in plant protein, vitamins, cellulose and various minerals, with high nutritional value and unique taste. What's more, wild vegetables have a significant effect on disease prevention and health care. For example, garlic with a small root has the effect of invigorating stomach and resolving phlegm. Rice dishes can strengthen the brain and improve eyesight. Portulaca oleracea has the function of cleaning gastrointestinal tract, and can prevent and treat acute and chronic enteritis or dysentery. Pteridium aquilinum can clear away heat and promote diuresis, reduce swelling and relieve pain, and also has the effect of promoting blood circulation and calming the nerves. The rice, flour, miscellaneous grains, meat, fish, poultry and eggs that people eat every day are mostly acidic in the body, and only the wild vegetables are alkaline after digestion and decomposition.

Seven, spinach spinach is rich in folic acid, and the folic acid content per 100g spinach is as high as 50mg, ranking first among vegetables. The biggest role of folic acid is to protect the fetus from neurological malformations such as spina bifida and hydrocephalus. Experts therefore advocate eating more spinach or taking folic acid tablets in the first 2 months of pregnancy. Folic acid is soluble in water, so you need to leave some water when cooking to keep its flavor. At the same time, a large number of B vitamins in spinach can also prevent common pregnancy complications such as pelvic inflammatory disease, mental depression and insomnia, and can effectively prevent chloasma in pregnant women. But spinach also contains a lot of oxalic acid, which will interfere with the absorption of trace elements such as iron and zinc.

Nowadays, many vegetables are poisoned by pesticides, which will have adverse effects on mothers and fetuses. So, I'll tell you 10 how to detoxify vegetables: 1, vegetables that are out of season and come on the market early often use a lot of pesticides and need to be washed several times because they don't conform to the climate. 2. It is best to wash vegetables with clear water. Vegetables with fat-soluble pesticides should not be washed easily with salt water. 3. Vegetables should not be cut before washing to prevent nutrient loss. Vegetables should not be eaten raw. If you must eat it raw, wash it several times. 5.

On the other hand, some foods are good things with high nutritional value in the eyes of ordinary people, but they may have negative effects on the fetus, such as; After the baby is born, it is prone to allergies. These are all things that mothers need to pay attention to when they are pregnant again. The following are some special examples of foods that pregnant women should avoid during pregnancy: avoid using safflower oil, sunflower oil shrimp, crab shrimp and crab have strong hormones. For pregnant women in hormonal imbalance, it is best not to eat, because it may aggravate hormonal imbalance. Pig liver Many people think that pig liver is very blood-enriching, but it has the function of breaking blood and will disperse the waste blood in the uterus; However, because there is no waste blood in the uterus during pregnancy, it is easy to cause early abortion. Leek and malt (sugar) are very effective for postpartum milk withdrawal, but they will affect the secretion of hormones and easily cause nausea and vomiting. Coix seed is used to eliminate abnormal cells in the body, but because fertilized eggs are not normal cells to the human body, the role of Coix seed may inhibit the growth of fertilized eggs, so try to avoid intake. Cold food such as lettuce salad, sashimi, iced drinks, fruits, etc. Although it needs to be cooled before delivery, lettuce and sashimi are easy to cause diarrhea because they have not been cooked and disinfected, and cold food will affect the respiratory organs and cause baby allergies. Too salty, too spicy, burnt and fried food is too salty and too spicy to stimulate the fetus; Burned food has an effect on the nerve mucosa of the upper respiratory organs, both of which are easy to cause baby allergies. Avoid aquatic products with abortion function. Many aquatic products, such as crabs, soft-shelled turtles and kelp, have the function of promoting blood circulation and softening hardness, which will have adverse effects on early pregnancy. Crab cold has the function of promoting blood circulation and removing blood stasis, especially crab claws have obvious abortion effect; Kelp has the effect of softening and resolving hard mass; Turtle has a strong function of dredging collaterals and removing blood stasis, so it has the disadvantage of abortion. Avoid smooth products. Cold and slippery products such as auricularia auricula, hawthorn, water chestnut, rice kernel and purslane have certain influence on early pregnancy. For example, pharmacological experiments have proved that rice kernels have a pleasant effect on uterine muscles and can promote uterine contraction, which may lead to abortion. Avoid hot food According to the principle of homologous medicine and food before labor, pregnant women should avoid eating hot food, because hot food will aggravate the internal heat of the human body and hinder the human body from gathering blood and raising a fetus. This kind of food includes mutton, dog meat, venison, pheasant, sparrow, seahorse, coriander, litchi, longan, apricot and almond. There is a saying in my hometown that pregnant women should not eat mother pork, and it is better to eat less mutton. It is said that the child may have epilepsy in the future. Although there is no medical evidence, this folk custom of trying not to eat, the growth of the fetus and the image temperament of the children born in the future are all related to the diet of pregnant women.

Xiong Bolong once asked in Wu Wu Ji: "Do all mothers who lack lips eat rabbits?" This is a question of disagreeing with this taboo. Undoubtedly, Xiong Bolong's questioning is reasonable. Eating rabbits is not necessarily related to missing lips. However, people don't just think that eating rabbits will lead to missing lips.

They all embody the same folk witchcraft superstition of "the same kind of feeling" (3) The taboo against eating donkey meat and horse meat is also very popular.

In ancient times, pregnant women were forbidden to eat dried carp, which was thought to cause children to give birth to sores. (8) Don't eat dog meat. Pregnant women in some areas of Heilongjiang don't eat dog meat. Otherwise, the children born in the future love to bite, and they also love to bite their nipples when they are nursing. Henan also has the custom of fasting dog meat for pregnant women. The area around Yucheng County in eastern Henan Province is especially taboo for women to eat black dog meat.

This kind of food includes mutton, dog meat, venison, pheasant, sparrow, seahorse, coriander, litchi, longan, apricot and almond. Pregnant women will have symptoms such as nausea, vomiting, headache and rapid heartbeat after drinking a lot of caffeinated drinks and food. Caffeine can also enter the fetus through the placenta, affecting fetal development. The metabolism of sugar in human body will consume a lot of calcium, and calcium deficiency during pregnancy will affect the development of fetal teeth and bones. Ginseng longan Chinese medicine believes that most pregnant women are deficient in yin and blood, and the participation of consumers will cause excessive consumption of qi and yin, which will aggravate early pregnancy reaction, edema and hypertension.

If pregnant women drink too much strong tea, especially strong tea, it will do harm to the fetus. Tea contains 2 ~ 5% caffeine, and every 500 ml of strong tea water contains about 0.06 mg caffeine. If you drink 5 cups of strong tea every day, you will consume 0.3 ~ 0.35 mg of caffeine. Caffeine has an exciting effect. Excessive intake will stimulate the increase of fetal movement and even endanger the growth and development of the fetus. A survey by Japanese experts also confirmed that if pregnant women drink 5 cups of strong tea every day, it may make newborns lose weight.
