Core tip: The standard supply of calcium for pregnant women in the first trimester is 800 mg per day, 1,000 mg per day in the second trimester, and 1,200 mg per day in the third trimester. Chen Qin, deputy chief physician of the Perinatal Nutrition Clinic of Guangzhou Women and Children\’s Medical Center, believes that many pregnant mothers do not pay attention to calcium supplementation during pregnancy, which will have a greater impact on the fetus and the pregnant woman herself. Calcium supplementation during pregnancy should also be properly coordinated. Don\’t rely solely on calcium tablets or milk.

Calcium supplementation during pregnancy is a common topic. Almost all maternity schools and obstetricians will emphasize that pregnant women should pay attention to calcium supplements. However, there are still waves of new mothers who “don’t know why.” Why do they need calcium supplements? Will taking calcium tablets calcify the placenta? Can drinking soy milk supplement calcium?
Chen Qin, deputy chief physician of the Perinatal Nutrition Clinic of Guangzhou Women and Children\’s Medical Center, believes that many pregnant mothers do not pay attention to calcium supplementation during pregnancy, which will have a greater impact on the fetus and the pregnant woman herself. Calcium supplementation during pregnancy should also be properly coordinated. Don\’t rely solely on calcium tablets or milk.
If you don’t supplement calcium during pregnancy, you should be careful after giving birth to a height of 1.6 to 1.58 meters.
During pregnancy, a woman\’s body loses a lot of calcium because all the calcium needed for fetal development comes from the mother\’s body. If a pregnant woman is mildly deficient in calcium, her body will mobilize the calcium in the mother\’s bones to maintain normal blood calcium. If a pregnant woman is severely deficient in calcium, she will develop leg cramps and even osteomalacia.
Dr. Chen Qin said: \”The fetus is a robber. It will constantly rob you of calcium. If you find cramps in your legs, it means that the calcium deficiency is serious. If the bone calcium loss exceeds 10%, you may have osteoporosis. , after giving birth, you will find that your height has changed from 1.6 meters to 1.58 meters.”
In addition, calcium deficiency in pregnant women will also have adverse effects on the growth and development of the fetus. Abnormalities such as softening of the skull, wide bone sutures, and abnormal closure of fontanelles may occur after birth.
Notice! Calcium supplementation during pregnancy is unreliable
According to the recommendations of the \”Reference Intake of Dietary Nutrients for Chinese Residents\”, the standard supply of calcium for pregnant women in the first trimester is 800 mg per day, 1,000 mg per day in the second trimester, and 1,200 mg per day in the third trimester.
Calcium intake during pregnancy is mainly through diet. Some mothers drink milk to supplement calcium, some eat soy products, and some even eat dried shrimps or sesame paste to supplement calcium… Dr. Chen Qin pointed out that many expectant mothers have many ways to supplement calcium. It’s unreliable and it’s easy to get insufficient calcium intake.
Sesame paste supplements calcium to prevent overweight
Since every 100 grams of sesame paste contains 1170 mg of calcium, sesame paste is also known as the best food for calcium supplementation. However, tahini is very high in calories. If you eat a lot of sesame paste every day, it can easily lead to obesity.
shrimpSupplement calcium for skin and be careful of edema
The calcium content of shrimp skin is also very high, with 991 mg of calcium per 100 grams of shrimp skin. The problem is that it is unimaginable to eat 100 grams of shrimp skin every day, which is 2 taels.
Soy products supplement calcium to prevent the fetus from becoming too large
Many mothers don\’t like to drink milk, so they drink soy milk or eat soy products to supplement calcium. However, the calcium content of soy milk is very low, only 10 mg/100g. Although the calcium content of tofu is slightly higher (116-138 mg/100g), But the biggest problem is that the protein content is too high. Eating so many soy products every day can easily cause the fetus to become too large.
Calcium supplementation with bone broth can be ignored
When 1 kilogram of meat and bone soup is boiled for 2 hours, the calcium content in the soup is only about 20 mg. Using meat and bone soup to supplement calcium is far from meeting the needs. In addition, the fat content of meat and bone soup is very high, and you will also eat fat when drinking the soup. Pregnant mothers should pay attention to obesity.
Taking calcium tablets after a meal is equivalent to skipping a meal
Since calcium easily combines with oxalic acid, phytic acid, etc., which affects the absorption of calcium, Chen Qin reminds you not to take calcium tablets after meals, otherwise not only will it not be absorbed, but it will also cause constipation. The best time to take calcium tablets is at night before going to bed. Because blood calcium concentration is lowest in the latter half of the night and early in the morning, it is most suitable for calcium supplementation.
Nutritionists recommend calcium supplementation program during pregnancy
So, how to properly supplement calcium during pregnancy? Dr. Chen Qin pointed out a calcium supplement program for us during pregnancy. Pregnant women\’s calcium intake can be divided into 4 sources: daily diet 300-400 mg, milk 580 mg/500 ml, multi-dimensional tablets 100-250 mg daily, and calcium tablets 300 mg or 600 mg daily.
Early pregnancy calcium supplement plan: 800 mg per day, which can be arranged as a normal diet + 1 cup of milk (250 ml)
Second trimester calcium supplement plan: 1,000 mg per day, which can be arranged as a normal diet + 2 cups of milk (500 ml) + multivitamin tablets, or a normal diet + 1 cup of milk + calcium tablets (300 mg)
Second trimester calcium supplement plan: 1200 mg per day, which can be arranged as normal diet + 1 cup of milk (250 ml) + calcium tablets (600 mg). You can drink less milk in the third trimester because it can easily lead to excessive weight gain.
It should be noted that calcium supplementation should not be excessive and can be supplemented as needed. Since a reasonable diet is closely related to the individual, expectant mothers can also make arrangements on their own or under the guidance of a nutritionist.
