Generally speaking, summer is the best time for parents to supplement calcium for their children. If parents can supplement calcium for the kids in a right way, the effect of calcium supplementation can be doubled and the normal growth of children can be accelerated greatly.
99% of calcium is stored in the human bones and teeth. Therefore, calcium deficiency can seriously endanger the health of bones and teeth of children. Many parents have already known that it is important to supplement calcium for children, but they do not know how much calcium should be supplemented. In order to supplement calcium for children scientifically and reasonably, it is necessary for parents to know the amount of calcium needed by children every day. The newborn infants should supplement 400 milligrams of calcium every day. When they grow up to six months old, the calcium supplementation should be increased to 600 milligrams. When they further grow up to three years old, they should supplement 800 milligrams of calcium every day. If excessive calcium is supplemented for children, children can not absorb extra calcium at all. Therefore, parents should supplement calcium for the kids in a right amount.
Calcium With Vit D
In summer, the sunlight is very strong. Ultraviolet rays contained in sunlight can accelerate the synthesis of vitamin D and raise the absorption rate of calcium for children. Ultraviolet rays can make 7-dehydrocholesterol inside the skin synthesize into vitamin D which plays an important role in accelerating the absorption of calcium and phosphorous for children. Therefore, children should often eat the foods which contain abundant vitamin D, such as liver, milk, roe and egg yolk. In addition, cod-liver oil should also be supplemented for the newborn babies. In summer, parents should let the children bask in the sun frequently, and then vitamin D can be produced inside the children's skin. In autumn and winter, the sunlight is relatively weak. It is especially necessary for parents to supplement vitamin D for children.
In summer, parents can provide the foods which contain rich calcium for the kids, like milk, beans, dried peeled prawn and sesame paste. At the same time, the foods which contain rich salt and protein should be avoided, as they can increase the loss of calcium from urination. The foods containing phosphoric acid, magnesium and caffeine should also be avoided, as they can seriously affect the absorption and excretion of calcium. It is important for parents to provide a kind of scientific diet for children.
