Introduction of calcium Calcium is one of the minerals that are abundant in the human body, accounting for about 1.5%-2% of body weight. The human body needs a lot of calcium, and infants grow most rapidly in the first year of life, with a 3-fold increase in weight and an O.5-fold increase in length in 1 week, which requires a large amount of calcium salts deposited in bone tissue to promote the formation of new bone and the growth of bone. The amount of calcium in the body increases from about 25 grams at birth to 75 grams, and when the body does not absorb enough calcium, bone calcium is mobilized to maintain normal blood calcium for normal physiological activity and neurological function. Infants and children can only achieve the normal bone development needs if they maintain a positive bone calcium balance, i.e. an average daily bone calcium deposition of more than 140 mg. The role of calcium 1, calcium can make up the bones and teeth of the human body, can account for 1.5% and 2%, if lack of it will cause osteoporosis; 2, calcium can relieve nerve excitability; 3, calcium can participate in the process of blood clotting in the human body, some people can not easily stop bleeding after bleeding, which is related to the lack of calcium; 4, calcium can maintain the activity of many enzymes; 5, calcium can maintain the permeability of the body’s cell membranes. How much calcium does a baby need at each age? In infancy, children within six months need 300 mg of calcium per day; after six months, they need to take 400 mg of calcium per day; after reaching one year of age, they need 600 mg per day; over 4 years of age, they need 800 mg per day; in adolescence, they need 1000 mg of calcium per day; the intake of calcium in daily life only meets 1/3 to 1/2 of the amount needed. Ways to determine the calcium deficiency of babies Because of the growth of children rapid growth and less outdoor activities and sun exposure, it often causes insufficient absorption of calcium and leads to various manifestations of calcium deficiency. Children can be judged from the following aspects: ① they often show excessive sweating, which is not related to temperature, especially sweating on the head after sleeping, so that the child’s head is constantly rubbing the pillow, and the occipital bald circle can be seen behind the skull after a long time; ② they are irritable, not interested in the surroundings, and sometimes parents find that the child is not as lively as before; ③ they have night terrors, often waking up suddenly at night and crying more than once. How to properly supplement calcium calcium from food list of 10 kinds of foods with high calcium content (the value is the number of milligrams of calcium per 100 grams of food) calcium supplement recipes: seaweed mixed with bean curd Ingredients: 200 grams of aquafaba bean curd, 200 grams of aquafaba kelp, 100 grams of cooked lean pork, 25 grams of carrots, 40 grams of cucumber, 15 grams of sesame oil, 25 grams of cooked soybean oil, soy sauce, vinegar, salt, monosodium glutamate, garlic cloves, sesame paste, scallions Each appropriate amount. Make: 1. cut the bean curd into inch-long shreds, blanch it in boiling water, take it out and drain the water; 2. wash the kelp, carrot and cucumber, cut them into inch-long shreds, cut the cooked lean meat into shreds, chop the shallots and garlic cloves; 3. equip all kinds of shreds into the plate, sprinkle the shallots with minced, add all the seasonings when serving, mix well and eat. Calcium is the “building material” of the human body. Just like building a house requires steel and cement, bricks and tiles, calcium is essential for the growth and development process of babies. However, if you simply give your baby calcium, it will appear that your baby is still deficient in calcium. The scientific way of calcium supplementation is to supplement vitamin D3 before calcium supplementation. If you simply supplement calcium without vitamin D3, then the calcium supplement will not be fully absorbed and utilized, and thus the child will still be deficient in calcium even after taking a lot of calcium supplements. The easiest way to supplement vitamin D is to let your baby enjoy a comfortable sunbath …… Direct calcium method Direct calcium method that calcium products contain calcium elements, by taking calcium products calcium, divided into organic calcium and inorganic calcium: organic calcium absorption gentle, suitable for small babies; inorganic calcium absorption depends on stomach acid, about 1 year old baby stomach acid less, absorption is not good. If your baby is less than 2 years old, it is recommended not to choose inorganic calcium. The common types of organic calcium are calcium lactate, calcium amino acid chelate, calcium gluconate, calcium citrate, calcium lactate, etc. Common types of inorganic calcium are calcium carbonate, calcium phosphate, active calcium (calcined from shells of shellfish, irritating, not recommended), etc. Indirect calcium supplementation method Indirect calcium supplementation method means taking cod liver oil and AD drops containing VD to indirectly promote calcium absorption. The VD content of cod liver oil is relatively low and is used for daily nutritional supplementation, suitable for babies with less serious calcium deficiency; the VD content of AD drops is high and suitable for babies with serious calcium deficiency. Baby calcium misconceptions Three major misconceptions about baby calcium supplementation The latest child health experts statistics show that many babies born in China suffer from “neonatal hypocalcemia”, which is what we usually mean by “baby calcium deficiency”. Parents should pay attention to the three major misconceptions about calcium supplementation, in addition to the correct calcium supplementation for their babies under the strict guidance of doctors. The finer the calcium supplement, the better. With regard to calcium supplementation, the finer the calcium powder, the better. The particle size of the calcium supplement is only a physical change and does not fundamentally change the absorption rate of calcium in the body. The absorption rate of calcium is only between 30% and 40%, and there is no such thing as “95%” absorption rate. After taking calcium supplements, calcium first enters the bloodstream to form “calcium-containing cells” and then goes through a complex process of change to penetrate the outermost hard layer of the bone and fix it to the bone inside. Myth 2: Excessive calcium supplementation is harmless Infants and children should take calcium supplements strictly under the guidance of a doctor, as taking too much calcium can cause great harm to growth and development. Expert tip: A very small number of babies who take too much calcium for a long time may also suffer from “ghost face syndrome”: with a big mouth, nostrils facing the sky, a prominent upper lip, a flat nose, and two eyes far apart. These children are also associated with wasting, mental retardation, heart murmurs and other diseases. Myth 3: All children of all ages are suitable for calcium supplementation Doctors tell us that as long as children can chew their own food, eat lumpy food, and receive regular sun baths, they generally do not need additional calcium supplementation. The best way is to take a certain amount of calcium and cod liver oil. Because cod liver oil is rich in vitamin D, it reduces the alkalinity in the intestine and promotes the absorption of calcium in the small intestine, so this is the key to ensuring that your baby does not suffer from calcium deficiency.
