The choice of food and drink during pregnancy is a door-to-door study. Do you know what kind of pregnancy foods and drinks are the healthiest? Do you know what kind of pregnancy foods and drinks are suitable for you? Mothers can look at the list of foods and drinks listed here today. Suitable for pregnant women 1. Rich in VC Fruits and Vegetables - Preventing Preeclampsia Preeclampsia is a serious complication that can easily occur in the third trimester and affects the safety of pregnant women and fetuses. When the relevant experts investigated the diet of hundreds of pre-eclampsia and healthy pregnant women, they found that pregnant women who received less vitamin C per day from food had lower levels of VC in their blood. The risk of developing pre-eclampsia was that of healthy pregnant women. 2-4 times. Therefore, expectant mothers should pay attention to the intake of fresh vegetables and fruits rich in vitamins during pregnancy, and the daily intake should not be less than 85 mg. 2. Honey - promotes sleep and prevents constipation In natural foods, the energy needed by brain neurons is highest in honey. If a pregnant woman drinks a glass of honey water before going to bed, the sedative effect can ease the discomfort of multiple dreams, awakening and sleeping, and improve the quality of sleep. In addition, when mothers and mothers drink water every morning and afternoon, if they put a few drops of honey in the water, they can relieve laxatively and effectively prevent constipation and hemorrhoids. 3. Fish - Avoid fetal brain dysplasia Nutritionists point out that DHA contained in fish is an essential fatty acid, which plays an important role in the formation of the fetal brain cell membrane. A number of research experts surveyed tens of thousands of pregnant women and found that eating fish regularly after pregnancy can contribute to the growth and development of the brain cells of the fetus, and the less chance of eating fetal brain dysplasia. If pregnant women do not eat fish throughout the pregnancy, the possibility of fetal brain dysplasia increases by 1/8. Experts suggest that pregnant women eat at least 1-2 times a week to absorb enough DHA to meet the fetal brain development needs. In addition, eating fish once a week during pregnancy also helps reduce the likelihood of preterm birth. 4. Yellow bean sprouts - to promote the construction of fetal tissue The growth and development of the fetus requires protein, which is the basic material for fetal cell differentiation and organ formation. The growth of the fetus is like building a solid building foundation. Yellow bean sprouts are rich in proteins necessary for the fetus, and can also be stored in the pregnant woman's body to supply the consumption and postpartum lactation during childbirth. It can also prevent postpartum hemorrhage, constipation, and improve the quality of breast milk. Therefore, bean sprouts are ideal for pregnant women. 5. Eggs - Promote Foetal Brain Development The nutrients contained in the egg are comprehensive and balanced, and the seven nutrients are almost completely utilized by the body. In particular, choline in the egg yolk is called "memory" and it is very beneficial to the development of fetal baby's brain. It also enables pregnant women to maintain good memory. Therefore, eggs are also ideal for pregnant women. In addition, high-quality protein in eggs can be stored in pregnant women, helping to improve the quality of breast milk after birth. To remind you that eating more eggs is of course beneficial to the health of pregnant women and fetuses, but not as much as possible. It is advisable to eat 3-4 meals a day, so as not to increase the burden on the liver and kidneys. 6. Melon and watermelon - help eliminate lower extremity edema Late pregnancy in pregnant women due to inferior vena cava compression, blood flow is blocked, the foot and ankle often appear postural edema, but usually disappear after a rest. If the edema does not disappear after a rest or when the edema is severe and there are no other abnormalities, it is called pregnancy edema. Melon cold and sweet, rich in water, you can quench your thirst and diuretic. If simmered with squid, pregnant women's lower limb edema can be reduced. Watermelon has the effects of detoxification, diuresis and swelling, regular consumption will increase the urine output of pregnant women, and thus excrete excess water in the body, and help eliminate lower extremity edema. 7. Apple - promote brain development and prevent fetal malformations Apple is rich in zinc, which is closely related to human memory. Zinc is conducive to the development of the hippocampus at the edge of the fetal cerebral cortex and contributes to the acquired memory of the fetus. Therefore, the apple has a reputation as a “fruit of puzzleâ€. Zinc deficiency in pregnant women can present with a variety of zinc-related anomalies, such as low fetal weight, developmental arrest, congenital heart disease, multiple bone deformities, and hypospadias when the central nervous system is damaged. In particular, if pregnant women have very low blood zinc levels, serious consequences such as miscarriage or stillbirth may occur. Pregnant women eat 1-2 apples a day, which can meet the fetus's demand for zinc. 8. Kelp and iodized salt - to avoid fetal intelligence At 3-5 months of pregnancy, fetal brain development depends on the maternal supply of sufficient thyroxine. If pregnant women lack iodine, the synthesis of thyroid hormone in the body will be affected, so that the fetus can not obtain the necessary thyroid hormone, resulting in brain dysplasia and low IQ. Even if you add enough iodine after birth, it is difficult to correct the mental decline caused by congenital problems. Therefore, pregnant women must pay attention to iodine during pregnancy. In addition to the intake of iodized salt, it is best to add iodine-rich foods from foods, especially in iodine-deficient areas. The most common food is kelp with the most iodine content. It is the ideal iodine supplement food for pregnant women. As long as you ensure that eating 1-2 times a week kelp, you can meet the needs of fetal development. 9. Pumpkin - Prevent pregnancy edema and hypertension Pumpkin fruit and fruit nutrition is extremely rich. Pregnant women eat pumpkin flowers and fruits, not only can promote the development of fetal brain cells, enhance their vitality, but also prevent pregnancy edema, high blood pressure and other pregnancy complications, promote blood clotting and prevent postpartum hemorrhage. Take 500 grams of pumpkin, 60 grams of glutinous rice, boiled pumpkin porridge, can promote liver and kidney cell regeneration, while the recovery of appetite and physical strength after early pregnancy reaction has a catalytic effect. 10. Sunflower seeds - reduce the risk of miscarriage Sunflower seeds are rich in VE, and VE can promote the anterior pituitary gonadotropin-secreting cell function, increase ovarian function, increase the number of follicles, increase luteal cells, enhance the role of progesterone, promote sperm production and enhance its vitality. Medical treatment often uses VE to treat infertility and threatened abortion, so tocopherol is named after this. If the pregnant woman lacks VE, it is easy to cause fetal movements or it is not easy to become pregnant again after abortion. Eat more foods rich in VE during pregnancy, such as eating 2 tablespoons of sunflower oil per day, to meet the needs, help to ease the birth and reduce the risk of miscarriage. 11. Fresh sour fruit - prevent fetal neural tube malformation Bayberry, strawberry, cherry, kiwi, pomegranate, grape, etc. are all fruits with sour taste. These fruits are rich in folic acid, which is a very important substance for the development of embryonic neural tube. If folic acid is lacking during pregnancy, it will affect the development and formation of embryonic neural tube, leading to spina bifida or no brain children. Therefore, in early pregnancy should pay attention to eat more fresh sour fruit, reduce the risk of fetal neural tube malformation abnormalities. 12. Celery - Prevention of pregnancy-induced hypertension The celery is rich in nutrients such as wolfberry, carotene, VC, niacin and mannitol, especially certain nutrients in the leaves are more abundant than the celery stalks. It has the functions of refreshing heat and cooling blood, refreshing urine and calming blood pressure. . Regular consumption in the third trimester can help pregnant women lower their blood pressure. It also has preventive and therapeutic effects on iron deficiency anemia and complications such as preeclampsia caused by pregnancy-induced hypertension syndrome. 13. Potato - reduce morning sickness Potatoes are rich in vitamin B6 and have an antiemetic effect. The most prominent manifestations of pregnant women in the first trimester are nausea, vomiting and poor appetite, and eating very little. If you eat more potatoes, it can help pregnant women relieve the symptoms of greasy and vomiting, and potatoes are also health foods for preventing pregnancy-induced hypertension. 14. Animal liver - to avoid iron deficiency anemia Blood volume during pregnancy is higher than before pregnancy, blood is diluted, physiological anemia occurs in pregnant women, and iron deficiency anemia occurs when iron deficiency is insufficient. Pregnant women and fetuses need iron. Once they are deficient, they are prone to anaemia during pregnancy or premature birth. Therefore, we must pay attention to the intake of iron-rich foods during pregnancy. All kinds of animal liver iron content is high, but once a week to eat, while eating these foods, it is best to eat foods rich in VC or acid, such as lemon, orange, etc., increase the absorption rate of iron in the intestine . 15. Walnuts, sesame seeds - nourishes and promotes fetal brain development Walnuts and sesame have the effect of qi and nourishing blood and have a tocolysis effect. Pregnant women in the first trimester have nausea and dislike lipids and are not even willing to smell it. If pregnant women eat some walnuts and sesame, which are rich in cephalins, lecithin and DHA, it will have a role in offsetting lipids. Lipids are the main raw materials for the development of fetal brain cells. Once they are lacking, they will affect the development of the nervous system. However, excessive consumption of walnuts and sesame seeds can easily cause weight gain. Eat 2-3 walnuts a day or 1-2 cups of sesame paste. Suitable for pregnant women Fresh fruit juice Choose any kind of fruit, such as apples, pears, watermelons, oranges, etc., and use a juicer to squeeze a glass of fresh juice for yourself. Different kinds of fruit juices can also be mixed together according to individual tastes to make a thirst-quenching and healthy beverage. Milk or yogurt Mothers insist on drinking milk or yoghurt every day and can take calcium and protein better during pregnancy. mineral water Mineral water is a good choice for expectant mothers. It is clean, cool and thirsty. The mother will drink pure mineral water, and feel more proud of themselves - "Dear baby, mother drink the most natural drink with you!"
How do WiFi Camera Work ?
Monitoring cameras can also be installed without a network, but some functions cannot be used, such as remote monitoring. In order to make it easier for you to understand the knowledge related to the surveillance camera, I will use popular language to popularize science for you.
1: Camera introduction
Camera is an intelligent device that can capture and record video and monitor the environment in real time. It can not only record video, but also detect moving objects, sound, smoke, and even recognize faces.
The advantages of the camera are very obvious. It can help people better monitor the safety of their homes or offices, and help protect the safety of family members or office staff. In addition, it can also provide real-time video monitoring, provide more security guarantees, and help people better grasp the current security situation.
Among them, "intelligent camera" is a new technology in recent years, which can monitor the environment in real time and conduct intelligent identification. The intelligent camera adopts high-definition camera technology, which can clearly capture the on-site images within the monitoring range and conduct real-time monitoring. It can also analyze the captured pictures to identify the designated person or object, thus realizing intelligent monitoring.
In addition, the smart camera can also support remote monitoring. You can remotely view the real-time image of the camera through your mobile phone or computer, allowing users to view the image of the camera anytime and anywhere, to better protect the security of your home or office.
At present, cameras have been widely used in the security industry to monitor buildings, parks, schools and other places to protect the safety of the people. It can also be used in commercial places to help businesses achieve intelligent management, improve business environment and improve service quality.
2: Working principle of camera
The working principle of the camera is to reflect the light to the sensor, convert the signal captured by the sensor into a digital signal, and finally send it to the computer to display the image. Then the camera can capture the static and dynamic images in the picture.
The sensor of the camera is the most important part. It can capture light and convert it into electrical signals. There are many types of sensors, the most common are CCD and CMOS sensors, which can be used to capture images.
