Mothers, against your little one has the following performance or not, pay attention to it! Calcium 1, often manifested as excessive sweating, independent of temperature, especially after sleep, head sweating, so that the child’s skull constantly rubbing the pillow, after a long time behind the skull can be seen occipital baldness circle. 2, mental irritability, not interested in the surrounding environment, sometimes parents find that the child is not as lively as before. 3, night terrors, often waking up suddenly at night, crying. 4, after 1 year old children show late teething, some children are still not teething at 1 and a half years old, delayed closure of the anterior chimney, often after 1 and a half years old is still not closed. 5. The forehead is high and prominent, forming a square skull. 6, often have beaded ribs, is due to the lack of vitamin D, rib cartilage hyperplasia, the cartilage hyperplasia of the ribs connected like beads, often oppression of the lungs, so that the child ventilation is not smooth, easy to suffer from bronchitis, pneumonia. When children are seriously deficient in calcium, the muscles and tendons are flaccid. If the abdominal wall muscles, intestinal wall muscle relaxation, can cause the intestinal cavity of gas and the formation of abdominal expansion such as frog abdomen. If the spinal tendon relaxation, can appear hunchback. 1 year old children learn to walk, if the lack of calcium, can make the bone softening, standing body weight makes the lower limbs bending, some manifested as “X” shaped legs, some manifested as “O” shaped legs, and prone to bone fracture. 1, infants grow fast, calcium needs relatively more, but the daily dietary calcium intake of our residents often do not reach the recommended intake standards. Therefore, it is now advocated that infants should be supplemented with 1/3 of the recommended amount of calcium from 2 weeks after birth, and at least until the age of 2, otherwise it is easy to lack of calcium. 2. First of all, although the traditional dietary structure of Chinese people has many advantages, it lacks foods with high calcium content. 3. Many people do not understand what is the correct and effective way to take calcium supplements. Some people would say that calcium tablets are full of calcium, calcium supplementation effect must be the best. In fact, this is not true. Calcium in calcium tablets are mostly inorganic calcium (calcium carbonate) or organic calcium (calcium gluconate), etc. The absorption rate of these synthetic calcium preparations is not as ideal as that of milk calcium. The absorption rate of milk calcium can be as high as 40%, while the absorption rate of some organic calcium is only about 20%. The absorption rate of inorganic calcium is comparable to that of milk calcium, but it is more irritating to the stomach and intestines. Therefore, the best choice for calcium supplementation is through foods that are high in calcium, such as milk calcium-rich formulas. Vitamin D is the carrier of calcium absorption by bone marrow. Calcium’s Edge tablets contain vitamin D, which can multiply calcium absorption. Again, the absorption of calcium needs the help of vitamin D3, otherwise calcium will only “come and go in a hurry” in the body. Vitamin D3 is beneficial to the deposition of calcium on the bones and reduces the loss of calcium. Therefore, fortified with vitamin D3 milk or milk powder calcium supplementation effect will be better. Dietary Calcium Reference Intake for Chinese Residents: Age Daily Reference Intake (mg) 0-6 months 300 1-4 years old 400 4-7 years old 600 7-11 years old 800 11-18 years old 1000 Pregnant women Middle 1000 Pregnant women Late 1200 Breastfeeding 1200 1. Eat foods with high calcium content, such as milk, yogurt, cheese, loach, mussels, snails, shrimp, small shrimp, kelp, crispy fried fish, oysters, peanuts, sesame paste, tofu, pine nuts, collard greens, cauliflower, cabbage, and oilseed rape, and so on. 2, more sports Sports Sports can make the muscles pull each other, strongly stimulate the bones, strengthen blood circulation and metabolism, reduce calcium loss, delay bone aging, and at the same time conducive to the body’s absorption of calcium in the diet. 3, more sunshine Ultraviolet light can promote the synthesis of VD in the body is conducive to the absorption of calcium. But ultraviolet rays can not penetrate the glass so you can not sunbathe through the glass. Or use ZZ-2 ultraviolet ray therapy instrument to irradiate the skin to promote calcium absorption. 4, eat a good breakfast 5, on the oxalic acid containing vegetables first blanch to destroy oxalic acid (oxalic acid can affect the absorption of calcium), and then cooking. Such as: collard greens, cauliflower, spinach, amaranth, cabbage, mustard greens, snow peas, bamboo shoots. 6.Separate supplementation Supplementation of calcium and supplementation of other minerals separately. 7.Take calcium tablets containing vitamin D supplement. 8.Consume before going to bed, or between lunch and dinner is more likely to be absorbed.
