The following is a brief introduction to the content of the video: Guest introduction in this issue: Zhang Ye: former director of nutrition department of 309 Hospital of China People's Liberation Army, nutritionist, member of China Nutrition Society, engaged in nutrition work for 30 years, and worked in the clinical front line for a long time. Whether a child is calcium deficient can be judged from the following aspects: 1. Night sweats, especially after falling asleep, sweating heavily on the head, especially after crying. 2. Poor sleep, night terrors and crying at night. I often wake up suddenly and cry at night. 3. Abnormal temperament, eccentric temper, crying, fidgeting and difficult to look after. 4. Pillow bald ring Because the child is mentally agitated, it is not easy to fall asleep, and the head keeps rubbing the pillow for a long time; The hair at the back of the dry spoon is polished to form pillow baldness. 5. Some children with late and irregular teeth have not yet teethed at the age of 65, 438+0 and a half, or their teeth are poorly developed, arranged irregularly, their teeth are loose and fall off prematurely. 6. Infantile eczema: mostly occurs on the top of the head, face and behind the ears, and can be serious to the whole body. Red spots and papules appear on the affected area, and then become blisters, erosion and scabs. 7. Growing late, learning to walk late, osteoarthropathy: Children with calcium deficiency can learn to walk with hairy legs after 0/2 months. Due to osteomalacia, some are X-shaped legs, some are arched legs, muscle weakness and leg bone pain. 8. The front chimney door is delayed to close, often not closed after] years and a half, forming a square skull. 9. There are often beaded costal cartilage hyperplasia, and the cartilage hyperplasia of each rib is beaded, which often oppresses the lungs. Healthy children are prone to bronchitis and pneumonia because of poor ventilation. 10. Muscle and tendon relaxation When children are severely calcium deficient, if the abdominal wall muscles and intestinal wall muscles are relaxed, gas can accumulate in the intestinal cavity, forming a frog-shaped abdomen. If the tendons in the spine are slack, hunchback, chicken breast and sternal pain may occur. 1 1. Others: Children with calcium deficiency often have symptoms such as loss of appetite, poor mental state, convulsions, indifference to the surrounding environment, mental retardation and decreased immune function. 12. Overweight and overweight babies are more prone to calcium deficiency because their demand for calcium increases. Therefore, parents with fat children should pay special attention to their children's external strength and internal calcium deficiency. First of all, milk and dairy products are the best food sources to get calcium from the diet. Milk and dairy products are not only high in calcium, but also easily absorbed by the human body. At the same time, dairy products also provide high-quality protein and rich vitamins for their growth. In addition, soybeans, bean products, seafood (such as fish, shrimp, kelp, seaweed and so on. ), sesame and green leafy vegetables are rich in calcium, especially shrimp skin. Spinach, bamboo shoots, lettuce, water bamboo and other foods contain more oxalic acid, which combines with calcium to form water-insoluble calcium oxalate, which will affect the absorption of calcium and should not be eaten more. Vitamin D can promote intestinal absorption of calcium, and foods rich in vitamin D (such as animal liver, egg yolk, cream, etc. ) when supplementing calcium, you should supplement it appropriately. The skin can synthesize vitamin d by itself in the sun. Teenagers should do more outdoor sports to ensure a certain sunshine time. Exercise can promote bone formation and bone growth, thus achieving twice the result with half the effort. Due to the differences in eating habits and food preferences, it is difficult for some children to significantly increase their calcium intake through dietary channels. At the same time, some teenagers suffer from lactose intolerance (abdominal distension and diarrhea after drinking milk) and cannot take calcium through milk. In this way, calcium supplementation has become a simple and easy method. Calcium products with good safety, high calcium content, easy absorption, scientific formula and good taste are the first choice of calcium agents.
