Several nutrients that pregnant women should supplement should not be ignored when eating foods rich in zinc
Eating foods rich in zinc should not be ignored.
Zinc, a trace element known as the "flower of life", is one of the components of more than 100 enzymes in the body. Once the body is deficient in zinc, many enzymes can not play its role, which is easy to cause metabolic disorders. Zinc plays an important role in promoting intellectual development. From 10 to 18 weeks of embryo to 8 months of fetal development, the proliferation of brain nerve cells basically ends, which can be described as "completed at one time". The number of brain nerve cells at birth is about the same as that of adults. As we all know, the material basis of intelligence is the nerve cells in the brain. Zinc plays an important role in promoting nucleic acid replication and protein synthesis of brain nerve cells. zinc deficiency not only affects the division and number of brain cells, but also affects the visual and organ development of fetus. Recently, researchers in the United States have found that if pregnant women with low plasma zinc levels are given zinc supplements, the baby's birth weight and surroundings will increase. According to a survey of more than 4,000 pregnant women and nursing mothers in eight provinces and cities in China, it is found that none of their zinc intake meets the supply standard recommended by the Chinese Nutrition Association (zinc intake for pregnant women and nursing mothers should reach 20 mg per day), and the incidence of zinc deficiency is about 30%. This is related to the fact that the diet in our country is mainly based on plant food, the content of zinc is low and the absorption of zinc is interfered by oxalic acid and phytic acid in grains and vegetables. Relevant experts suggest that pregnant women should pay attention to zinc supplements from food. Generally speaking, animal food has more zinc than plant food. Foods with high zinc content include oysters, rotors, scallops, conch, clam, animal liver, bird meat, lean meat, egg yolk, mushrooms vacuum pumps , beans, wheat malt, yeast, cheese, kelp, nuts and so on.
Second, supplement food and refined products containing DHA in an appropriate amount.
Liu Zelun, director of the Maternal Education Research Center of Beijing Medical University, suggested that according to overseas experimental examinations and data, DHA (22 carbon hexaenoic acid) contributes to the growth and development of brain pyramidal cells and retinal video cells of fetuses and infants, and pregnant women should properly supplement DHA from the fourth month of pregnancy.
DHA is a polyunsaturated fatty acid, which requires the development of fetal brain nerve cells. Brain nutritionists have shown that DHA, choline and phospholipids are important substances that make up the neurilemma of the cerebral cortex and are important structures for storing and processing information. DHA is an indispensable highly unsaturated fatty acid in human brain nutrition, which can maintain the integrity of brain cell membrane, promote brain development and improve memory. It is reported that the content of DHA in Japanese maternal milk is higher than that in Australian and American maternal milk. American scholar Collister believes that Japanese children's intelligence, in addition to prenatal education, early education development and other reasons, but also with the fetal brain development of the mother's intake of DHA substances. DHA is not mysterious. After ingesting walnut kernels containing natural linoleic acid and linolenic acid, the liver can synthesize DHA. Sea fish, fish oil and soft-shelled turtle also contain DHA substances to choose from. Of course, DHA preparations can be supplemented if necessary, such as DHA capsules approved by experts.
It is necessary to supplement foods rich in folic acid
Experimental studies in Britain and other seven countries in the early 1990s showed that less than 3 months of pregnancy was the critical period for fetal neural tube development. Adequate folic acid supplementation to pregnant women resulted in a significant decrease in neural tube defects and a significant decrease in anencephaly and congenital spinal fissure rates. Recently, researchers in California have found that folic acid supplementation before or in the early stages of pregnancy can reduce the risk of cleft lip or palate by 50%, and reduce the risk of premature and low-birth weight babies. Therefore, women preparing for marriage and early pregnancy need to pay attention to folic acid-rich foods. Foods rich in folic acid are red amaranth, spinach best male masturbator , lettuce, asparagus, asparagus, beans, yeast, animal liver and apples, citrus, orange juice and so on.
Fourth, replenish adequate calcium
The fetus needs to absorb 30 grams of calcium from the mother throughout pregnancy, and the amount of calcium required increases sharply from the 30th week of pregnancy. Therefore girl using vibrator , pregnant women should pay attention to supplement enough calcium, supplement at least 1.2 grams of calcium every day butt , and take more food containing vitamin d to help the absorption of calcium. Foods rich in calcium and vitamin d are shrimp skin, oysters, light vegetables, milk, sardines, salmon, kelp, Loach, bean products, coriander, cauliflower, sesame paste, lotus seeds, sweet almonds, liver, egg yolk, mushrooms and so on. Calcium products can be replenished if necessary. Practice shows that calcium supplementation during pregnancy can not only contribute to the normal development of fetal bones, but also reduce the incidence of pregnancy induced hypertension and reduce the amount of postpartum hemorrhage.
Pay attention to the intake of foods rich in vitamin k in the later period of pregnancy
In the later stage of pregnancy, pregnant women should pay attention to the intake of foods rich in vitamin k to prevent postpartum newborn vitamin k deficiency caused by intracranial, gastrointestinal bleeding and so on. Vitamin k has the laudatory name of hemostatic hero, through intestinal absorption, the liver can produce prothrombin and clotting factors. Insufficient absorption of vitamin k, the reduction of prothrombin in the blood, easy to cause blood coagulation disorders, easy to cause haemorrhage. Pregnant women a month before the due date should pay special attention to eating more foods rich in vitamin k every day. For example, cauliflower, cabbage, spinach, lettuce, green leaves, sauerkraut and so on, vitamin K41 mg can be taken orally every day if necessary.
