1, the effect of protein powder on bones
The main raw material of protein powder is generally protein with high content. protein is the material basis of all life, an important part of body cells and the main raw material for human tissue renewal and repair. Every tissue of the human body: hair, skin, muscles, bones, internal organs, brain, blood, nerves, endocrine and so on. Are made up of protein, so diet makes people themselves. Protein is very important to human growth and development.
Whey protein in protein powder can promote bones, and lactoferrin found in whey has been proved to be directly beneficial to bone metabolism. In the study of cell culture, lactoferrin can promote the proliferation of osteoblasts and chondrocytes and increase their physiological content, which is more effective than other bone growth factors, such as IGF- 1 and TGFb. Lactoferrin plays a synthetic role in bone metabolism, which is of great significance for bone health and prevention of osteoporosis.
2. How to supplement calcium for children?
At present, there are more than 400 calcium agents in China, including domestic and imported calcium agents. The specific choice of calcium agents needs to be decided according to the characteristics of various calcium agents and the people taking them.
1, calcium carbonate
High calcium content, little side effect, low price and high absorption rate, up to 40%. Similar to milk, it is a calcium preparation that is easily accepted and widely used by the people of the whole country.
2. Calcium lactate
It is one of the traditional calcium supplement foods in China. Its advantage is solubility, but its disadvantage is low calcium content. These preparations are: calcium lactate, containing calcium13%; Calcium gluconate contains 9% calcium, and the content is lower after being made into tablets. It is unacceptable for people to take too many tablets every day to supplement calcium for adults 1000 mg.
3. Calcium ammonium phosphate
It is a commonly used calcium supplement variety in Japan, with a relatively high calcium content of 23.3%. It is also produced by Chengdu Pharmaceutical Factory in China. Each tablet contains 70 mg of calcium, which is moderate for the drug price. However, its disadvantage is that tablets are difficult to disintegrate and absorb, and because of high phosphorus content, it is harmful to renal insufficiency, so it is rarely used.
4. Calcium citrate
The calcium content is 2 1. 1%, which has good water solubility and better bioavailability than calcium phosphate. Its absorption does not depend on gastric acid, and it has effervescent tablets, which are more suitable for people to take.
5, active calcium
It is a calcium mixture formed by calcining biological calcium (shellfish) at high temperature. It contains high calcium content, but its aqueous solution is strongly alkaline and irritating to gastrointestinal tract, which is not suitable for the elderly with gastric acid deficiency. Eating with food can reduce gastrointestinal irritation.
6. Organic calcium
Amino acid calcium and protein calcium have been applied in China. In addition, calcium supplementation is not as much as possible. It is important to look at absorption. Every time the intake of elemental calcium exceeds 200 mg, the absorption rate will be reduced.

What does the child eat to supplement calcium?
Calcium should be supplemented according to the doctor's advice, diet should be adjusted when calcium is deficient, and appropriate calcium should be supplemented under the guidance of a doctor. Calcium carbonate has high calcium content, small side effects, low price and high absorption rate, which can reach 40%. Similar to milk, it is a widely used calcium preparation at present. To improve the absorption capacity of calcium, there is still a problem of absorption in calcium supplementation. No matter how much you make up, it's no use not absorbing it. At the same time, supplementing AD (cod liver oil) is helpful to the absorption of calcium, and more sunshine is also helpful to the absorption of calcium. In addition, the imperfection of the baby's gastrointestinal system will reduce the absorption of calcium, so it is necessary to supplement some beneficial bacteria in the intestine while supplementing calcium.
Diseases easily caused by calcium deficiency in children
First of all, convulsions
When the calcium and phosphorus in the baby's blood are obviously low, it will lead to "rickety hypocalcemia convulsion", also known as vitamin D deficiency tetany, commonly known as "hypocalcemia convulsion".
aetiological agent
The important role of calcium in blood is to inhibit muscle excitability and prevent excessive contraction. When the calcium level in the baby's blood drops and the inhibition is weakened, the muscle excitability will immediately increase, and people will involuntarily contract, that is, cramp.
Onset symptoms
The baby is crying and uneasy, and it is easy to be scared by the slightest sound. When Fan Xun was frightened, his wrist was bent, his thumb was close to his palm, and his other fingers were straight. Sometimes the legs are straight and crossed, the toes are bent down and the instep is arched, like dancing ballet. The attack lasts for a few seconds to a few minutes, and then it can relieve itself.
At the onset, the baby's consciousness is clear, and frequent attacks can be as many as 10 times a day. There will be severe laryngeal spasm, mainly laryngeal spasm. Generally speaking, there are more babies under 1 year. During the attack, the baby's glottis and throat muscles contract strongly, which makes it difficult to inhale and makes a terrible guttural sound. More serious will be delirious, or even suffocated.
Time of onset
Hypocalcemia convulsions mostly occur in the early stage of infantile rickets, or infants suffering from rickets are treated with vitamin D, and in late spring and early summer, when children with rickets start to get more sunshine. Infants are prone to hypocalcemia convulsions when they have fever, infection and hunger. Infants with hypocalcemic convulsions are often accompanied by other manifestations of rickets, such as hyperhidrosis, lack of sleep, easy awakening, hair loss on the headrest and baldness on the headrest.
Emergency treatment
In case of laryngeal spasm in children, adults should try to open their mouths and pull out their tongues to keep the respiratory tract unobstructed. At the same time, insert a long hard object (such as chopsticks) between your teeth to prevent biting your tongue. Be sure to pay attention to grasping chopsticks to prevent it from entering the respiratory tract and aggravating the obstruction. After the initial treatment, no matter whether the laryngeal spasm stops or not, the child should be sent to the hospital for further examination and treatment immediately.
Second, abdominal pain.
aetiological agent
Free calcium ion in blood is low, and neuromuscular excitability is high. When the intestinal smooth muscle is slightly stimulated, it will contract strongly, that is, gastrointestinal symptoms such as intestinal spasm and abdominal pain will appear.
Onset symptoms
The baby's irregular stomachache has nothing to do with external factors such as diet and diarrhea. The stool examination is normal, and taking drugs such as anthelmintic drugs, digestive drugs and spasmolytic drugs has no effect.
Third, the fontanelle is not closed.
/kloc-babies over 0/8 months old should go to the hospital to take X-ray photos of their bones and have blood tests if the front fontanel is not closed. If the X-ray photos show calcium deficiency in the blood, it means that the baby has "nutritional rickets", which is what the people call "rickets".
aetiological agent
When the baby's calcium intake is insufficient or the intestinal absorption of calcium is reduced, the calcium deficiency in the body directly affects the deposition of calcium to the bone. If the calcium in the body cannot be deposited in the bones normally, the bones will become soft. The skull grows rapidly in infancy, and one of the earliest symptoms of calcium deficiency is insufficient calcification of the skull, which leads to skull softening due to rickets (commonly known as "ping pong head").
Onset symptoms
The inner plate of the sick baby's skull becomes thinner, and the parietal bone or occipital bone feels like table tennis. If not found and treated in time, the anterior fontanel will be enlarged, the margin will be softened, and the closure will be delayed. At the same time, it will be accompanied by common symptoms of rickets such as night terrors, irritability, hyperhidrosis, restless sleep, crying, jumping, shaking the head and softening the skull.
Matters needing attention in children's calcium supplement
To supplement calcium for your baby, you must first know whether you need to supplement calcium. Not all babies need calcium supplements. If the artificially fed baby consumes 700 ~ 750 ml of formula milk every day, calcium intake is enough. Generally, breast-fed babies can supplement calcium. Older infants who drink less formula milk, such as 8 ~ 12 months, can also consider calcium supplementation. In addition, babies diagnosed as calcium deficiency by doctors should be supplemented with calcium.
In addition, parents should also know some basic knowledge about calcium supplementation:
1, cod liver oil and calcium powder need not be taken at the same time. Generally, cod liver oil can be taken at breakfast, and calcium preparation can be taken before bed or between lunch and dinner to reduce the factors affecting calcium absorption in food.
2. Young parents should not buy calcium products themselves, because some calcium products have low calcium content, 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 recommended to consult relevant specialties and listen to the doctor's reason before buying.
3. Familiar with some factors that promote calcium absorption and inhibit calcium absorption.
1) factors promoting calcium absorption
Vitamin D can promote the absorption of calcium in small intestine and the deposition of calcium in bones. Medical Education | Education Network The adequate supply of protein in the diet is beneficial to the absorption of calcium, which may be due to the fact that amino acids produced by protein digestion can combine with calcium to form soluble calcium salts, thus promoting the absorption of calcium. When the body's demand for calcium increases, the absorption rate of dietary calcium will increase. For example, adults can only absorb 20% of dietary calcium, while infants and pregnant women can absorb about 50% of dietary calcium. In addition, when the demand for calcium increases, the storage of dietary calcium will also increase.
2) Factors inhibiting calcium absorption
When the food contains too much oxalic acid or phytic acid, not only the calcium in the food itself is not easily absorbed, but also the absorption of calcium in other foods, such as spinach, bamboo shoots, amaranth, Chinese milk vetch, edamame, water bamboo, onion, grass and so on. So before cooking these vegetables, you can blanch them with boiling water to remove oxalic acid and phytic acid. If you eat too much fat, the free fatty acids produced after digestion cannot be absorbed in the intestine, and are easily combined with calcium, which is discharged with feces, reducing the absorption of calcium. Excessive intake of dietary protein will increase the excretion of calcium in urine. Therefore, we should pay attention to a reasonable diet structure to avoid excessive intake of fat and protein. In addition, when dietary fiber is consumed too much, the combination of its components and calcium will also reduce the absorption of calcium, so children are not encouraged to eat too much coarse grains.
