Pregnant women are a "special" group. Calcium is not only lost, but also used to provide a healthy bone and teeth for the formation of fetus to help the development of the heart, nerves, muscles, and coagulation capabilities of the fetus.If the intake of calcium does not meet the standard, the fetus will quietly "steal" the calcium in the mother’s bones; if the calcium supplement is too much, it will cause other diseases.Therefore, it is important to supplement calcium correctly, safely, and effective!
1. "calcium element" during pregnancy is very important
During pregnancy, fetal growth requires a lot of nutrition, and these nutrients need to be obtained from the mother. Therefore, the amount of calcium needed during pregnancy is much more.If pregnant women do not consume enough calcium, it may cause the pregnant woman’s bones and teeth to lack calcium deficiency, cause waist and leg pain, bone pain, hand and foot cramps, affect the fetal development of the fetus, and lead to calcium deficiency in the newborn.
Second, the demand for calcium at each stage during pregnancy is different
1. Early pregnancy
In the early stages of pregnancy, the fetal growth rate is slow, and the demand for calcium for expectant mothers is basically consistent with before pregnancy. It needs to be supplemented by about 700 ~ 800 mg per day.During this time, a balanced diet and exposure to the sun can basically meet the needs of yourself and your baby.
2. In the middle of pregnancy
The second trimester is the fastest period of the baby’s development. The demand for calcium in pregnant women has greatly increased. It needs to be added with 800 ~ 1200 mg of calcium every day. In addition to taking from food, it also needs to take additional calcium supplement products.
3. The early pregnancy
By the stage of pregnancy, the skeletal calcification speed of the fetus suddenly increased. It can be said that 80%of the calcium stored in the fetus is derived from this period, so pregnant women need about 1,000 to 1200 mg of calcium per day.In addition to drinking milk and eating calcium -rich foods, you also need to continue to take calcium supplements.
3. How to choose calcium supplement products
Choose a regular prescription, buy regular brands, and do not buy miscellaneous calcium.When buying, pay attention to the details of manufacturers, batch numbers, shelf life and other details to avoid buying fake and shoddy products.If you can’t choose, you can go to the hospital for a doctor.
The survey shows that the per capita calcium intake of my country is about 479 mg, which is the principle of being missing.In order to reduce the number of daily consumption of pregnant women and reduce gastrointestinal burden, it is recommended to choose high concentration of calcium, such as calcium carbonate.If a pregnant woman lacks VD, the absorption rate of calcium elements will be reduced, so taking vitamin D together can increase the absorption rate of calcium.
1. Active calcium: There are many related products, but there have been negative news of heavy metals such as arsenic and mercury detected. The safety needs to be sophisticated.
2. Calcium carbonate: safe and reliable, the most common.However, the self -absorption rate of calcium carbonate is also different. Because its dissolution requires lower pH, it is not suitable for people who lack gastric acid.
3. Calcium acid: It is easy to dissolve and can be taken in lack of gastric acid, but the content of calcium is low.
4. Calcium phosphate: It can be used as a reinforcement, but it is not easy to dissolve, and it is too high in phosphorus. It is not suitable for people with bad kidneys.
5. Calcium acid calcium: good absorption and high utilization rate, but due to the time of the discovery, side effects remain to be verified.
4. Which foods contain calcium
Pregnant women can eat more calcium -rich foods, such as milk, kelp, seaweed, nuts, beans, shrimp skin, sesame, etc.
Milk is the best source of calcium supplementation in meals. The content of milk calcium is 100 ~ 120 mg/100 grams. Milk calcium absorption rate is high, which is the first choice for food supplement.In the middle of pregnancy and not as good as a mothers, it is best to drink 500 ml of milk products every day.
Eat more beans or soy products, and usually eat about 100 grams of soy products to take 100 mg of calcium.Especially in the production process of north -south tofu, plaster or brine used as a coagulant, so the calcium content is very high.However, if you choose to use glucosate as a coagulant, this kind of lipid tofu is relatively low in calcium.
The calcium content of kelp, seaweed, shrimp skin and other foods is high, and the absorption rate is also good, but pregnant women who are allergic to seafood products should not be eaten.
5. Regarding calcium supplement, have you stepped on these "thunder"
1. Calcium supplementation causes placental calcification
There is calcium deposition in the placenta, which does not mean that the calcium in the body is super large. In our Chinese diet and food, the calcium content is relatively small.Calcium must be supplemented during pregnancy. The so -called placental calcification. The placenta is level 3 or 3+no calcium supplement. This concept is wrong.
2. There are more calcium supplement, the baby’s head will be hard, it is not easy to give birth
There is no scientific basis for this statement. The baby’s skull is not a complete bone. There is a gap between the bones and the bones, and the gap between the gap and the soft tissue between the gaps and the door.During childbirth, the fetus’s head enters the birth canal. Because of the squeezing, the cranial gap will overlap mild, which is conducive to the fetal head delivery, and gradually closed completely after birth.
3. If you have kidney stones, you can’t supplement calcium
Many mothers will worry that if you have more calcium supplement, you will get kidney stones, so you will refuse calcium supplementation when you get kidney stones, thinking that calcium supplementation will increase the stones.In fact, some stones are not caused by too much calcium supplement, but have problems with calcium metabolism in their bodies.Therefore, there are many calcium demand for pregnant women, that is, stones can still normally supplement calcium.
Finally, remind you: Human calcium levels are very low at night, and the absorption rate of calcium supplementation is higher. Before going to bed at night, it is the ideal calcium supplement time.In addition, do not take calcium tablets on an empty stomach. It is best to take half an hour after dinner before taking it, because sufficient mucu can interfere with oxygic acid and promote the absorption of calcium.
