Calcium is one of the important elements in human body. Therefore, it is very important to supplement calcium for children. Here are several correct calcium supplementation methods, hoping to give readers some help.

A fasting unqualified calcium supplement health care product

The main reason of calcium deficiency in human body is that the unreasonable dietary structure leads to insufficient calcium intake. Therefore, parents should supplement calcium for their children mainly by adjusting their diet. In general, you don't need to take calcium-containing health care products. Recently, the spokesman of the Ministry of Health reported the results of the current follow-up supervision and inspection of the products, among which Zhenghe goat milk calcium tablets, ultra-micro calcium granules and Jinde calcium 0 middle-aged and elderly type 12 calcium supplement health foods meet the requirements, while the production conditions of individual food companies producing Haijianqiang bone meal do not meet the requirements of relevant health standards. It can be seen that there are still fakes in calcium health care products marketed, which should attract the attention of consumers.

Second, you should eat more calcium-containing foods to supplement calcium.

In our traditional family diet, the calcium content per100g of rice is 30mg, the flour is 20mg, the lettuce in vegetables is 24mg, the wax gourd is 34mg, the spinach is 44mg, the Chinese cabbage is 35mg, the carrot is 32mg and the beans are 26mg. When food and vegetables are added together, the calcium provided every day only accounts for about 30% of the calcium needed by the human body every day. According to the standards recommended by the Nutrition Society of China, the daily calcium requirement of primary school students under 9 years old is 300mg, and that of10-1200mg for primary and middle school students aged 5 years old. According to the results of several national nutrition surveys, the daily calcium intake of most primary and middle school students in China is only about half of the recommended amount, which is mainly due to the traditional dietary structure of most families. Therefore, parents should let their children eat more calcium-containing foods, such as bean products, fish, shrimp, kelp and so on. Fresh green leaves and vegetables contain more calcium, which is a high-quality source of calcium intake for human body, such as rape and celery. When eating green leafy vegetables, you should stick to eating them every day, change varieties, and don't overeat or eat them suddenly.

Third, cooking methods should be scientific

The key to supplementing calcium from food and eating foods with high calcium content is absorption. Therefore, cooking methods should be scientific. For example, when eating tofu and bean products, it is best not to eat them with onions, onions and spinach. When eating spareribs and shrimps, put some vinegar, and calcium will easily dissociate into ionized calcium, which can be absorbed and utilized by human body. It takes a long time to cook big bone, so that children can eat bone marrow, which is a very nutritious and good calcium source. Avoid eating spinach with high-fat foods such as tofu and milk, because spinach contains oxalic acid, which can form calcium oxalate with calcium in tofu and milk, which affects the absorption of calcium. Adding vitamins to ordinary food will increase the calcium content. For example, adding vitamin A, vitamin D and calcium-containing substances to milk will greatly increase the calcium content. When eating fruits and vegetables raw, it's best not to peel them, but to eat them with skin, because the skin of fruits and vegetables contains a lot of calcium. In addition, vitamin D plays an important role in promoting the absorption and utilization of calcium. There are two important sources of vitamin D: one is food. Eggs, milk, vitamin D milk and cod liver oil all contain vitamin D; The second is self-manufacturing. Vitamin D can be synthesized by human skin under sunlight, and it can meet the needs of vitamin # by sunbathing for more than -92 hours every day. Of course, children diagnosed with calcium deficiency by hospital examination can take some calcium supplements, and at the same time, the interaction and influence of food ingredients should be avoided. When there is too much phosphate in the diet, it will reduce the absorption of calcium, and the combination of oxalic acid and calcium in plants will produce insoluble oxalic acid, which is not conducive to human absorption. If the intake of protein is too high, the intestinal pH will decrease, which will also affect the absorption.

Develop the habit of drinking milk

Milk is an ideal food with comprehensive nutrition. Milk contains six ingredients of food (protein, fat, carbohydrates, vitamins, minerals and water) and three functions of food (supplying human body with heat and energy; Provide "materials" for teenagers to develop or adults to repair injuries; Maintaining and regulating physiological functions). It can be said that milk contains nutrients suitable for human physiological needs for human growth, development and health maintenance, and all kinds of nutrients collected by milk are of high quality, so milk is praised as "white blood". Therefore, parents should let their children drink 250 grams of milk every day, so as to get 275-300 milligrams of calcium from it, which is beneficial to the nutrition and health of children.

How to give calcium to children

Once upon a time: when I went to work and opened the newspaper, I would see advertisements for calcium supplementation one after another; Going home, the door is often stuffed with the promotion of calcium supplements and health products; In the evening, it is overwhelming on TV that "calcium should be supplemented"; Visiting the door, the greeting of the mother's meeting is "Does your child take calcium?"

However, when all Chinese people regard themselves as calcium-deficient people and take this calcium without hesitation, Henan Business Daily set off a "giant calcium storm" at the end of last year. Up to now, although there has been a conclusion about whether Giant Calcium is "toxic" (the Ministry of Health held a press conference on February 3, 2004/KLOC-0 and informed that Giant Calcium products are safe, and there is no illegal behavior in giant calcium production enterprises), consumers are no longer as steadfast as before in supporting "calcium products", especially when supplementing calcium for children, and they are extremely cautious in choosing and choosing, mainly. We have no intention to discuss whether we should give our children "giant calcium" now, and we have no intention to make a list of the endless calcium products in China. We just want to judge from an objective and scientific point of view: children of different ages have different ways to supplement calcium.

0-2 years old need to take calcium.

The reason why calcium should be added

1. Newborns' weight and height increase rapidly, so they need calcium supplementation.

2. The ratio of calcium and phosphorus in milk is 1.2: 1, which does not meet the physiological needs of infants (the optimum ratio of calcium and phosphorus is 2: 1) and is not conducive to the absorption of calcium by intestinal wall. Therefore, it is necessary to pay attention to calcium supplementation when breast milk is insufficient or there is no milk for artificial feeding.

3.0-2-year-old babies have less outdoor activities, and their diet is not rich enough, so they will lack calcium absorption. At this stage, the possibility of rickets or rickets symptoms due to calcium deficiency is particularly high, so they also need to take calcium supplements.

Three principles of selecting calcium agent

1. Listen to the doctor's advice.

At present, there are various calcium preparations on the market, such as calcium powder, calcium tablets, or calcium capsules. Parents had better not buy calcium products by themselves, because some calcium products contain very low calcium, such as calcium gluconate; Some contain more heavy metals, such as products forged from marine oyster shells; Some are more irritating to the stomach, such as calcium carbonate. It is appropriate to consult a specialist.

2. The product has a regular batch number.

Since it is a drug or a nutritional product, it must be reviewed by the State Drug Inspection Bureau or the Ministry of Health. Therefore, when buying calcium for your baby, you must see whether the product has a drug batch number or a health care product name.

3. It should be acceptable to children.

In addition to considering the absorption rate and the way of taking this kind of calcium, children must also consider whether they like it or not. At present, there are calcium tablets with fruit taste and animal shape on the market, and these products will undoubtedly win the favor of children. If some calcium has a high absorption rate, but the taste is not good or the tablets are too big to swallow, it is better to give up such calcium supplements and choose what the baby likes.

Points for attention in calcium supplementation

1. Vitamin D must be added to supplement calcium.

Appropriate vitamin D supplementation can promote the absorption of calcium. Without vitamin D, the absorption of calcium is only 10%. Therefore, babies who supplement calcium must add vitamin D (cod liver oil, Yikexin, etc.). However, at present, there are a kind of calcium preparations, such as calcium amino acid, calcium threonate, vitamin C and so on, which can be actively absorbed by the human body without the help of vitamin D.

2. Don't take calcium phosphate.

Excessive intake of phosphorus will form water-insoluble calcium phosphate and be excreted. Will inevitably lead to the loss of calcium. Because of food and water problems, Chinese people's phosphorus intake has greatly exceeded the standard. Therefore, when buying calcium supplements, mothers must see the ingredients of calcium, and never give their babies phosphorus-containing calcium supplements!

3. Magnesium affects the absorption of calcium.

Excessive magnesium can not only affect the absorption and utilization of calcium, but also cause motor dysfunction. For infants and young children, the magnesium content in the body is enough through food intake, and no additional supplement is needed. It is recommended not to blindly supplement calcium containing magnesium.

4. Less salt in food is beneficial to the absorption of calcium.

When the sodium intake is high, the body will reduce the absorption of calcium. Therefore, children who are taking calcium supplements should strictly control the intake of salt and feed 1-2 times a day with slightly salty food.

5. Phytic acid and oxalic acid in food affect calcium absorption.

Foods such as spinach, bamboo shoots, amaranth, edamame, water bamboo, onion and so on contain too much oxalic acid or phytic acid, which not only makes the calcium in the food itself difficult to be absorbed, but also affects the absorption of calcium. Therefore, before cooking these vegetables, they can be scalded in boiling water to remove oxalic acid and phytic acid.

6. Calcium and dairy products cannot be taken together.

If calcium tablets are added to milk, milk and calcium can easily combine to form clots, and not only calcium is not easily absorbed, but also milk is not easily digested. The correct method should be to supplement calcium to the child after most of the food in the stomach is emptied 1-2 hours after feeding.

7. Calcium should not be eaten with fatty foods.

Fatty acids generated after oil decomposition combine with calcium to form milk lumps, which are not easily absorbed by the intestine and eventually excreted with the stool.

You don't need to take calcium supplements over 2 years old.

Reasons for not needing calcium supplements

1. The growth rate has slowed down compared with infants aged 0-2 years.

2. Teeth have basically come out, chewing ability has been greatly enhanced, and gradually transition from parents' feeding to self-eating. As long as the diet is reasonable and the nutrition is comprehensive and balanced, it is enough to supplement the calcium needed for one day through food.

3. The chances of outdoor activities and sports increase, and the skin will synthesize vitamin D after being exposed to sunlight, which can promote children's absorption of calcium.

It is best to supplement calcium through exercise and diet.

1. After the skin is exposed to sunlight, it will synthesize vitamin D for the human body to use, so it is necessary to insist on letting children participate in outdoor activities, 0.5 to 1 hour every day; Even in winter, as long as there is no wind, you can go outdoors to bask in the sun after 9 o'clock in the morning. If you are sunbathing indoors, be sure to open the window, because the glass will block the penetration of ultraviolet rays.

2. As the saying goes, "medicine is better than food", here are some foods rich in calcium:

Milk and dairy products: cow, sheep, horse milk and its milk powder, cheese, yogurt, condensed milk, ice cream.

Fish, shrimps, crabs and seafood: crucian carp, carp, silver carp, loach, shrimp, dried shrimps, dried shrimps, crabs, kelp, laver, clams, sea cucumbers and snails.

Meat and eggs: mutton, pig brain, chicken, eggs, duck eggs, quail eggs, preserved eggs, pork floss, etc.

Beans and bean products: soybean, edamame, lentil, broad bean, bean curd, dried bean curd (100g dried bean curd can supplement 200mg calcium), bean curd skin, bean curd milk, etc.

Vegetables: celery, rape, carrot, sesame, coriander, potherb mustard, black fungus, mushrooms, etc.

Fruits and dried fruits: lemon, loquat, apple, black dates, preserved apricots, orange cakes, preserved peaches, hawthorn, raisins, walnuts, watermelon seeds, pumpkin seeds, peanuts and lotus seeds.

3. Mom should also pay attention to reducing the loss of calcium in the daily cooking process. For example, food should be stored fresh; Don't stir the milk when it is heated to avoid the loss of calcium; Dishes should be washed first and then cut, and should not be cut too finely. Add more water to stir-fry and don't cook for too long.

Intimate reminder

Excessive calcium supplementation is not beneficial.

Infants should take calcium supplements under the guidance of doctors, and excessive calcium supplementation will cause great harm to growth and development.

Too much calcium supplementation can make the fontanel of the baby close prematurely, and the head can not be fully enlarged with the development of the brain, which on the one hand forms microcephaly and on the other hand restricts the development of the brain;

Premature calcification and closure of bones limit the height;

Too much calcium in the bone makes the bone brittle and prone to fracture;

Eating too much calcium will also make children lose appetite and affect the absorption of other nutrients in the intestine;

A small number of children who have been seriously over-supplemented with calcium for a long time may also suffer from "grimace syndrome": they have a big mouth, a prominent upper lip, a flat nose, nostrils facing the sky, a long distance between their eyes and a strange expression. Such children are often accompanied by emaciation, mental retardation, heart murmur and other diseases.
