Vegetables are one of the essential foods for pregnant women, especially spinach. Because spinach is rich in folic acid, the folic acid content per100g of spinach is as high as 5 0 micrograms, ranking first among vegetables. The biggest function of folic acid is to protect the fetus from nervous system malformations such as spina bifida, hydrocephalus and yuannao. Therefore, experts advocate eating more spinach or taking folic acid tablets in the first two months of pregnancy. At the same time, a large number of B groups in spinach can also prevent common pregnancy complications such as pelvic infection, mental depression and insomnia. The only drawback is that spinach contains too much oxalic acid, which can interfere with the absorption of trace elements such as iron and zinc. The way to eliminate this disadvantage is to first pour spinach into boiling water and blanch it, then most of the oxalic acid will be destroyed and it will be safe to eat.

Best anti-vomiting food

Vomiting is one of the most uncomfortable reactions during pregnancy, which brings considerable pain to pregnant women. Is there a good way to prevent it? Miriam Eric, a nutritionist at Brigham Gynecology Hospital in Boston, USA, recommended two kinds of food, one is lemon juice, and the other is fried potato chips.

Miriam Eric believes that choosing foods suitable for pregnant women's tastes has a good anti-vomiting effect. Compared with ginger beer and soda biscuits, lemons and potatoes contain more vitamins, which is more beneficial to pregnant women.

Best drink

What is the best drink for pregnant women? Experts recommend green tea on the grounds that green tea is a trace element-free "rich mine", and zinc, which plays an outstanding role in fetal development, is one of them. According to the determination, pregnant women who often drink green tea consume as much as14mg more zinc per day than non-drinkers. In addition, green tea contains a lot of iron, so drinking green tea often can prevent anemia.

However, the traditional view is that tea should not be drunk during pregnancy, mainly because tannic acid in tea can interfere with the absorption of zinc, iron and other elements in food. Recently, researchers have found a way to kill two birds with one stone, that is, to seize the opportunity of drinking tea. Generally speaking, people have basically absorbed the iron in food within 30 -60 minutes after eating. At this time, drinking tea will not interfere with the iron absorption, but will benefit from zinc supplementation.

Best food for preventing premature delivery

Studies by Danish experts show that eating fish often can prevent premature delivery. They investigated pregnant women in Dele Islands, Denmark, and found that the average pregnancy was more than 5 days longer than that in other areas. The secret lies in the large proportion of fish in the diet, so it is speculated that a special fatty acid in fish has played a positive role.

Because of the prolonged pregnancy of pregnant women, the average birth weight of babies is higher than that of other regions107g, which lays a good foundation for future development, so this diet method is worth learning. The best snack for pregnant women, eating a little snack can broaden the supply channels of nutrients outside the main meal. Experts suggest that eating melon seeds, such as sunflower seeds, watermelon seeds and pumpkin seeds, has its "one skill".

For example, sunflower seeds are rich in vitamin e. Watermelon seeds are rich in linoleic acid, and linoleic acid can be converted into "brain gold" (dha), which can promote fetal brain development. The advantage of pumpkin seeds lies in their comprehensive nutrition, including protein, fat, carbohydrate, calcium, iron, phosphorus, carotene, vitamin b 1, and b2 nicotinic acid. Moreover, the proportion of nutrients is balanced, which is beneficial to human absorption and utilization.

Best sour food

Pregnant women are often interested in sour food, and it is really good for pregnant women to eat sour food. After a woman is pregnant, the placenta secretes a kind of chorionic gonadotropin, which can inhibit the secretion of gastric acid and reduce the omission of digestive enzymes, resulting in weakened appetite and decreased digestive function of pregnant women. Therefore, eating acid is undoubtedly a remedy for this reaction. At the same time, fetal development, especially bone development, needs a lot of mineral calcium, but the calcium salt can not be deposited to form bones without the help of sour food. In addition, sour food can promote the absorption of iron in the intestine, which is beneficial to both mother and fetus.

However, pregnant women must make strict choices when eating sour food. For example, pickled sauerkraut and vinegar products are delicious, but the nutrients are destroyed, and there are many carcinogens such as nitrite. There are many nutrients in hawthorn, but it can accelerate uterine contraction and lead to the risk of miscarriage, so it is best to "stay away from it" during pregnancy. Tomatoes, bayberries, cherries, grapes, oranges, apples, etc. are the best acid supplements, and pregnant women should eat more.

The best food for childbirth: The parturient needs sufficient productivity during childbirth, and the productivity comes from food. Among all kinds of foods, chocolate is the best, and American doctors praise it as the best food for childbirth. Chocolate is rich in nutrition and has many calories, such as100g chocolate contains 50g of sugar, and it can be absorbed by human body in a short time and quickly converted into heat energy (its digestion and absorption speed is five times that of eggs), which is tantamount to "sending charcoal in the snow" for pregnant women who desperately need heat energy. Therefore, eating a few chocolates during labor is expected to shorten the labor process and deliver smoothly.
