Calcium ion is involved in many physiological functions of human body, such as nerve excitability, muscle contraction and heart activity.
Abnormal calcium metabolism will affect the bone structure, especially children in the growing period, and will also affect the normal operation of many physiological functions.
In fact, calcium needs to be supplemented all year round. Sunbathing in spring, summer and autumn can promote calcium absorption, but in winter, the sun is weak, the cold light time is short, and calcium loss will be faster.
Therefore, we need to get calcium from other foods to supplement the body with calcium.
The best way to supplement calcium in winter is to eat more foods with high calcium content, such as shrimp skin, sesame paste, black sesame cake, dairy products, animal liver, eggs, fish and beans.
Especially for children, winter is a necessary stage for children to accumulate nutrition and lay the foundation for rapid and healthy growth in the coming spring.
If calcium supplementation is neglected in winter, the time difference of calcium deficiency in spring and summer will double next year, and it will be better to supplement it. Calcium will be "in short supply" when calcium is supplemented in the golden age of children's growth.
In short, from a scientific point of view, calcium supplementation in winter can make it grow faster in spring.
