General nutritionists often suggest that children use milk as the best calcium supplement source, because milk is easy to digest and absorb, and it is rich in calcium, and contains a variety of nutrients such as protein (protein food), minerals and vitamins (vitamin food), but the problem is that many children don't like to drink milk, or like to drink flavored flavored milk to increase the palatability and taste acceptance of drinking milk, but in this way they consume excess sugar. On the other hand, many oriental children are lactose intolerant, and drinking milk (especially fresh milk with better nutrition) will lead to diarrhea, so they will never stop drinking milk.
If children don't drink milk, they can choose some calcium tablet supplements with better absorption to supplement calcium for children. At present, there are many kinds of calcium tablets on the market, and calcium citrate is a relatively new generation of cheap and high-quality products, because calcium citrate does not need gastric acid activation and absorption, and its absorption rate is the best, and it does not have the disadvantage of carbon dioxide flatulence like calcium carbonate, and the solubility of citrate in blood is higher than that of oxalate which produces stones, so citrate will rob calcium in stone components. It has a function of preventing stones, which is better than other calcium. For children whose gastrointestinal function has not been fully developed, it can get a better calcium supplement effect. At present, it has become popular in nutrition medicine at home and abroad.
In addition to supplementing milk or calcium tablets, children should be allowed to exercise outdoors (sports food), which can not only improve the development of strong bones, but also expose children to sunlight to generate vitamin D3 to improve the absorption of calcium in the intestine.
In addition, it should be noted that many natural products advertised as "natural active calcium" and "rare calcium" in the market should be paid more attention to the use of children, because most of these natural products are sourced from the ocean. Due to environmental pollution, there may be doubts about heavy metal pollution if they are not carefully handled in the manufacturing process. The harm of heavy metals to children's young bodies will far exceed that of adults.
According to the statistics of WHO and the World Health Organization, the calcium intake of children in the world, including advanced countries, is only 30%-60% of the required amount. In most countries (especially the eastern countries and the third world countries with calcium deficiency in diet), most children who need calcium most in their growth are in a state of severe calcium deficiency. Therefore, in addition to the symptoms of calcium deficiency in children, such as growth retardation, rickets, tooth hypoplasia and hyperactivity, It even affects the intellectual development of the brain and the health (healthy food) in the future. If calcium can be supplemented from childhood, the development of bones, internal organs, brain, etc. will reach the best state, laying a good foundation for the health of the future.
