Parents believe that children should start calcium supplementation after half a month to one month after birth. In fact, this view is unscientific. Because the umbilical cord is cut after the fetus is born, the nutrient channel between the mother and the fetus is interrupted. However, the growth and development of children can continue. Therefore, the daily demand for calcium is not sufficient. Therefore, the correct method should be after birth. Calcium supplementation began in three days, and it was necessary to make up for children to be able to eat ordinary foods like adults.
We know that baby's nutrition comes mainly from milk, and breast milk is the best baby food. Every 100 milliliters of human milk contains 34 milligrams of calcium and 15 milligrams of phosphorus. The ratio of the two is 2.4:1. This ratio is most suitable for calcium absorption in the intestinal wall of infants. Therefore, breast-fed infants are less likely to have calcium deficiency or rickets. On the contrary, every 100 ml of milk contains 120 mg of calcium and 93 mg of phosphorus. From the absolute value of calcium and phosphorus, the amount of calcium and phosphorus in milk is indeed more than that of breast milk, but the ratio of calcium to phosphorus in milk is 1.2:1. This ratio is not in line with the physiological needs of infants, and it is also not conducive to intestinal absorption of calcium. Clinical observations have also confirmed that milk-fed infants are prone to calcium deficiency or rickets. Sometimes, although some parents give children a lot of calcium, the calcium deficiency in children is still very obvious. The reason is that parents do not correctly master calcium supplements.
The values ​​provided in the "Chinese Dietary Reference Intakes of Residents" published in 2000 are as follows:
Age group (years) calcium intake (mg/day)
0-0.5 300 mg/day
0.5-1 400 mg/day
1-4 years old 600 mg/day
4-7 years old 800 mg/day
When the baby begins to lack calcium, there will be a variety of symptoms. Let's work together to find out what kind of performance we have, so that we can know ourselves and ourselves before we can achieve victories.
1. In the early stage of mild calcium deficiency or calcium deficiency, the baby may have the following performance:
1 Stunned, irritated, disobedient, and cry;
2 restless sleep, such as not easy to sleep, night terrors, wake up early, cry after waking up;
3 There is a lot of sweating. It has nothing to do with the weather. Even if the weather is not hot, there isn't much clothing, and when you sweat, you sweat.
4 Because of irritability and sweat stimulation, the baby likes to shake his head when lying down. For a long time, the hair at the back of the head is polished to form a bald pillow.
2. When there is severe calcium deficiency, the baby may have the following performance:
1 There was a convulsion;
2 Late teething (usually 4 to 10 months after birth, the first deciduous teeth)
3 The station will be delayed and the time for walking will be late (usually children will stand alone when they are 1 year old and walk alone for 13 to 15 months), and chicken breast humps, roping legs, and muscle weakness will also appear;
4 Because the calcium deficiency will also cause the baby's immunity and resistance to fall, the baby often catches a cold, has a fever, and has a diarrhea. If your baby has the above symptoms, please go to a regular hospital.
Vitamin D
It can promote the absorption and storage of calcium, and vitamin D can be obtained directly from sunlight on the skin. The sun-dried baby can not use extra vitamin D.
The blood levels of vitamin D in babies born in autumn and winter are very low because the winter milk contains very little vitamin D. Therefore, it is best to supplement 400-800 IU per day (400-600 IU for a baby born in the South and 600-800 IU for a baby born in the North).
Fish, salmon and other fish contain a lot of vitamin D, and fried foods will inhibit the absorption of vitamin D, no matter how much the baby, it is best to eat less fried foods.
Vitamin D in eggs, vitamin C in fruits and vegetables, lactose in formula, and appropriate calcium and phosphorus ratios in the diet can all promote calcium absorption.
Do not think that if the baby eats a calcium supplement or a calcium meal is considered to be a successful calcium supplement, and you want to give your baby an extra calcium supplement, the mother must also pay attention to the following points:
1. Don't let calcium meet oxalic acid.
Spinach, pickled vegetables, leeks, spinach, bamboo shoots, onions, white rice, soybeans, etc. contain large amounts of oxalic acid, oxalic acid easily combined with calcium and affect absorption.
Therefore, it is best to put the vegetables in hot water during calcium supplementation, or take calcium products 2 hours before meals or 3 to 4 hours after meals.
2, calcium do not mix with the main meal.
Even if there is not much oxalic acid, if you take calcium products during meals, it will still affect the absorption of calcium, calcium mixed with food can only absorb 20%. As long as the stomach is stuffed with too many things, the effect is not very good. Calcium should be separated from breakfast, lunch and dinner by more than half an hour. Don't mix with your milk.
3, excessive calcium is not high
Calcium should also be given in appropriate amounts, and not as much as possible. Infants and young children daily intake of calcium is about 400 mg, if the intake of calcium greatly exceed the above criteria, may constipation, and even interfere with the absorption and utilization of other trace elements such as zinc, iron, magnesium, etc., may also lead to kidney Calcium deposition occurs in organ tissues such as cardiovascular, cardiovascular, etc., as a potential risk of kidney stones.
4, vitamin D and baby calcium tablets to eat separately
There are very few children who really lack calcium, and many children really lack vitamin D. The role of vitamin D is to allow calcium to fully absorb from the intestine, while ensuring that the body's calcium will not be lost from the urine. The daily intake of vitamin D in infants and young children should reach 400 international units. If the amount of vitamin D is not enough, it will show "calcium deficiency." Too much, it will produce vitamin D poisoning, causing calcification of various organs and blood vessels and other performance. Therefore, infants should eat calcium tablets without vitamin D, and supplement vitamin AD preparations such as cod liver oil, because these commercially available formulations have a fixed daily recommended dosage. Vitamin D-containing calcium tablets contain less vitamin D, and they need to be supplemented with other AD preparations such as cod liver oil, but this will make the daily amount of AD preparations to be readjusted, making simple things rather complicated.
5, the balance of calcium and phosphorus to reduce calcium loss
Under normal circumstances, the proportion of calcium and phosphorus in the baby's body is 2:1. In other words, calcium is twice as much as phosphorus. If the baby's recipe is precisely this proportion, the calcium absorption and utilization rate is high. What is the actual situation? Because parents mostly relied on their baby's tastes, excessive intake of carbonated drinks, cola, coffee, hamburgers, pizza, wheat germ, French fries and other foods, and these foods are the "rich ore" of phosphorus, resulting in a large number of phosphorus influx In vivo, the ratio of calcium to phosphorus is as high as 1:10. Once the amount of phosphorus is too high, the calcium in the body will “drive†out of the body and cause calcium deficiency.
6, calcium supplement magnesium
Calcium and magnesium are like a good pair. When the ratio of the two is 2:1, it is most beneficial to the absorption and utilization of calcium. Unfortunately, parents often pay attention to calcium, but forget to make up magnesium, leading to insufficient magnesium in the body, and then involving calcium absorption. Magnesium is more common in nuts (almonds, cashews and peanuts), soybeans, melon seeds (sunflower seeds, pumpkin seeds), grains (especially rye, millet, and barley), seafood (tuna, salmon, etc.) Shrimp, lobster) etc.
7, different calcium and zinc supplements
Calcium and zinc, if taken together, although zinc does not interfere with the absorption of calcium, but calcium can reduce the absorption of zinc, so the two together only play a role in calcium supplementation, zinc supplementation function can not be inhibited due to Play it out. The secret is that the two will compete with each other, resulting in an unreasonable ratio of receptors, so one type of absorption is more and the other is less.
The correct approach is to take two minerals separately, such as taking calcium in the morning and evening, and eating zinc at noon, at least 3 hours apart.
Baby calcium need to pay attention to what
1 Before giving calcium to your child, please go to a regular hospital to check the calcium content of your child.
2 Do not give the baby too sweet and sour taste stimulation.
3 The more calcium is not better, please calcium supplement under the guidance of a doctor.
4 Calcium is needed most at night, and is most easily absorbed.
