Five crises of calcium deficiency in children
1, poor mental state
Children's calcium deficiency is often manifested as poor mental state, loss of appetite, cramps, poor resistance, lack of interest in the surrounding environment, mental retardation and other symptoms.
2, cramps
Children will cramp if they lack calcium. Calcium plays an important role in enhancing the excitation transmission, excitation and contraction coupling of neuromuscular.
3, rickets
Calcium deficiency in the body can lead to rickets in infancy. The blood calcium concentration of such children may be slightly lower, but calcium supplementation can not solve the symptoms of rickets, because the disease problem occurs in vitamin D, so the most fundamental solution is to bask in the sun, eat more fish and supplement vitamin D appropriately.
4. Obesity
Eating more calcium can inhibit the formation of fat; Insufficient calcium intake can easily lead to fat accumulation. If children don't get enough calcium from food, the body will release calcium from bones into the blood, and the calcium concentration in fat cells will increase, thus promoting fat synthesis.
5, nails have small white spots
People's nails will show the health of their bodies. If a small amount of white spots appear on fingernails, it is usually the lack of blood or nutrients such as calcium and zinc. You can eat more high-calcium foods to improve.
Correct calcium supplement method
1, supplement calcium from food
Milk and dairy products are recognized as foods rich in calcium. Baby has absorbed enough calcium from breast milk or formula milk, so don't worry about calcium deficiency. After starting to contact complementary food, you can eat more foods with high calcium content, such as dark green vegetables, fish, meat, milk, tofu and so on.
Step 2 exercise
The World Health Organization suggests that children and adolescents should achieve at least 65,438+0 hours of moderate physical activity every day, and accumulate more than 420 minutes every week.
3. Proper sunshine
Staying in the sun for 10 to 15 minutes without sunscreen, umbrella and clothes is helpful to the production of vitamin D and the absorption of calcium in the body.
To solve the common misunderstanding of calcium deficiency, the delay of children's long teeth has nothing to do with calcium deficiency.
Although the firmness and stability of teeth are closely related to calcium, it does not mean that the baby's delay in teething is also a calcium deficiency problem! Usually, the reason why babies delay teething or not teething may be caused by diseases (such as hypothyroidism, hypothyroidism, Down syndrome, etc.). ), and it has nothing to do with calcium supplementation. Blind calcium supplementation is not helpful for teething.
