The three golden periods for children to grow taller, parents must grasp it, do not miss it. The basic stage school age: preschool (4-6 years old) is an important period for children’s growth and development, but also the basic stage for children to grow taller. 6 years old or so calcium supplementation, the future growth of children is very important, at this time, the human skeleton in the reserve period, the daily amount of calcium elements required for bone development is 800 mg per day. At this age, children may be partial to food, anorexia, calcium intake is seriously insufficient, affecting the calcium reserves in the bones, which will directly lead to short head, developmental height increase is reduced. Therefore, children in this stage need calcium supplementation. The sudden increase stage school age: 10-16 years old is the child development period, the child’s head is like a spring shoot, “whoosh” straight up. Studies have found that for every 30,000 milligrams of calcium absorbed by a child during this period, the child’s height can grow by 1 centimeter. The sprint stage of puberty; 17-25 years old for men and 16-23 years old for women, is the final sprint stage of growth. Studies have found that the epiphyseal cartilage has not really healed during this stage, and there is still a potential for 2-3 cm of growth per year. At this time, supplementing adequate amounts of calcium will be able to fully exploit their growth potential, so that they “a hundred-foot pole, a step further”. The three golden growth periods of children are like dominoes, one after the other, a continuous dynamic process, this stage is the basis for the next stage of growth. Children with insufficient calcium intake during the reserve period will be affected by improper diets and poor nutrition, and children who fail to consume sufficient calcium during the developmental period will inevitably be affected by the final sprint for height. Therefore, it is important to ensure adequate intake of calcium in all stages of a child’s life and not to take it lightly.
