Beautiful women have a sacred mission to nurture life. Young prospective parents all hope that their future babies will be healthy and smart. A scientific and reasonable health care diet during pregnancy will directly affect the healthy growth and development of the fetus.

　　From practical experience and professional From the perspective of planning a pregnant woman’s healthy meal, it is mainly considered from several aspects:

　　1. Is food safe?

　　Safety issues mainly include whether there is excessive food Additives, such as pigments, spices, preservatives, and whether they contain illegal chemical raw materials, residual pesticides, heavy metals, etc.

　　 Such as the Minamata disease in Japan: In the early 1950s, in a place called Minamata Town in Kumamoto Prefecture, southern Kyushu, Japan, there were some slurred mouths, dazed faces, hands and feet shaking, Patients with neurological disorders, who will not heal for a long time, will bend their bodies and die miserably. This town has 40,000 inhabitants. Over the past few years, 10,000 people have suffered from this condition to varying degrees. Later, similar symptoms were also found in other places nearby. Once shocked the world. The inheritance of Minamata disease is also very strong. After pregnant women eat seafood contaminated with methylmercury, it may cause babies to suffer from congenital Minamata disease, and even the offspring of some healthy people (may be mildly injured, without obvious symptoms) Escape bad luck. Many children with congenital Minamata disease have movement and language barriers, and their symptoms resemble polio, which shows that it is not easy to eliminate the effects of Minamata disease. Therefore, environmental scientists believe that heavy metal pollution in sediments is a "time bomb" in the environment.

　　2. Is the food hygienic?

　　Is the food used by pregnant women contaminated with bacteria and viruses? Is the raw and cooked chopping board used when making dishes? , Raw and cooked plates, raw and cooked cutting and cutting tools are separated? Is the food within the shelf life, is it spoiled? Is the tableware washed and disinfected as necessary? Is the food in the refrigerator stored in a bacteriostatic container?

　　 For example: tinplate canned foods need to be eaten once after opening. If there are surpluses, you need to transfer the remaining foods to a hygienic storage box suitable for refrigerators, because the tinplates are in the refrigerator. It is easy to breed a large amount of Salmonella in humid and low temperature conditions, which can easily cause diarrhea in pregnant women, and can cause miscarriage or premature birth in severe cases.

　　 The same situation should be an important reminder: some families habitually put the fried chicken legs, fish or meat back on the raw cutting board used for cutting and cutting with a raw meat cutting knife ; Some put the fried dishes back into the plate of fresh lettuce and raw meat... Many people are surprised at such things, but for pregnant women, there are many hidden health and safety risks.

　　3. Is the food fresh and contains sufficient nutrients?

　　Whether the nutrients in the food of pregnant women are sufficient will affect the health during pregnancy and the growth and development of the fetus. Such as: high-quality protein, essential fatty acids, folic acid and other vitamins, iron, zinc and calcium and other necessary minerals; such as insufficient intake of folic acid can cause fetal neural tube defects.

　　Folic acid is present in many of our common foods, and some foods have higher levels of folic acid. Such as dark green vegetables: for example, rape, pakchoi, spinach, asparagus, green cauliflower; beans include soybeans, mung beans, kidney beans and so on.

　　4. Are individual nutrients in food excessive?

　　 Excessive nutrients in food can also cause hidden health risks for pregnant women and the fetus, such as: calories Excessive intake of nutrients protein, fat, and carbohydrates can cause maternal and child food-borne obesity, pregnancy diabetes, etc.; excessive intake of protein and calcium will cause fetal growth, premature fontanelle healing, and induce hidden troubles of dystocia.

　　 Daily intake of moderate amounts of protein can be increased by about 5 grams per day during early pregnancy compared with non-pregnancy period; 15 grams per day can be increased during the second trimester; approximately 20 grams can be increased during the third trimester. Excessive intake of protein during pregnancy will produce a large amount of harmful substances such as hydrogen sulfide and histamine in the human body, which can easily cause bloating, loss of appetite, dizziness, fatigue and other phenomena. At the same time, excessive protein intake can not only cause increased nitrogen in the blood, but also easily lead to increased cholesterol and increase the pressure of renal glomerular filtration.

　　A moderate amount of fat intake is of great significance to increase the immunity of pregnant women and promote fetal brain development, but excessive intake will cause fat accumulation and easily cause adverse effects on pregnant women’s cardiovascular health.

　　Pregnant women who like to eat sweets will consume too much sugar. In addition to adding a lot of calories, it will also be detrimental to the health of the pregnant woman and the fetus. Too much blood sugar will increase the consumption of calcium in pregnant women It will also increase the burden of kidney sugar excretion in pregnant women. In addition, excessive intake of sugar during pregnancy is also a cause of future congenital dental diseases. In addition, medical research shows that ingesting too much sugar will weaken the body''s immunity, reduce the resistance of pregnant women, and be susceptible to bacterial and viral infections, which is not conducive to the health of pregnant women and fetuses.

　　5. Are food cooking methods appropriate?

　　 Reasonable cooking methods will allow pregnant women to better absorb food nutrition and reduce unnecessary irritation And infection. Try to avoid irritating foods, especially hot and spicy seasonings. Also avoid eating raw meat and eggs.

　　 Foods that have not been fully processed by cooking are very likely to contain a lot of bacteria and parasites. For example, the risk of parasites such as liver flukes, lung flukes and even schistosomiasis in sashimi fish and shrimp is very high However, eggs that are not fully mature will contain a lot of Salmonella, which will pose a great threat to the healthy development of the liver, kidney, lungs and fetus of pregnant women, and may even cause miscarriage or premature delivery. In Shanghai in the 1980s of our country, residents often consumed a parasite-containing clam, which caused a large outbreak of hepatitis A, and many pregnant women suffered miscarriage or premature birth.

　　Pregnant women should also choose dishes made with light, low-salt diet and low-temperature cooking methods. The oily and thick flavor of fried, fried, roasted and roasted dishes will have a certain effect on the digestion and absorption of pregnant women. Some fried dishes will also produce some harmful substances, for example: carbohydrate-rich foods will produce cancer-producing acrylamide when fried at high temperatures, while protein will not produce when kebabs are under high temperature and smoke. Less strong carcinogens, such as: triphenylbenzene pyrene and dimethylamine in polycyclic aromatic compounds.

　　6. Pregnant women should eat fresh, unprocessed natural foods.

　　Fresh and natural foods, especially foods that have not been processed by industrial fine processing, will have their own unique nutrients. For example: eating staple foods can eat more raw grains: beans, grains, potatoes, will make pregnant women absorb more B vitamins and dietary fiber, not all rice and white noodles in the food, you should try to avoid eating instant noodles , Small food; meat should eat more fresh, less dried meat, cured meat, bacon, barbecue.
