What is the most effective and safe way to supplement calcium for children? Here are some suggestions for parents: 1. Breastfeeding is recommended for newborns because breast milk contains the calcium needed for metabolism in the baby’s body; artificially fed babies need to add supplementary foods, such as eggs, lean meat, soy products and animal liver, which are rich in calcium and can supplement their calcium intake. 2.How to choose calcium-rich foods? The calcium environment of all kinds of organisms on earth varies greatly, and the calcium content of seawater ranks fifth among all kinds of elements, so plants and animals immersed in seawater are ideal foods for calcium supplementation. In addition, shrimp skin, sesame paste, dairy, eggs, beans, nuts and dark-colored vegetables are all good foods for calcium supplementation. 3, calcium in the body transit process, must have the assistance of vitamin D. Vitamin D can regulate calcium and phosphorus metabolism through a series of complex transformations, thus promoting bone formation. At the same time, we should pay attention to let the children to do more outdoor activities and receive sunlight to promote the synthesis of vitamin D in the body. 4, calcium and phosphorus are a pair of close partners, however, if too much phosphorus intake, will affect the absorption of calcium. The general ratio of calcium to phosphorus is 1:1.2 to 1:1.5 both compared to pay special attention to supplemental calcium, because phosphorus is widely available in nature’s food. 5, the daily diet of our residents to plant foods, which contain more oxalic acid, phytic acid, cellulose, these substances combined with calcium, the formation of insoluble material tribute, thus affecting the absorption of calcium. In order to reduce the formation of the substance, you can first blanch some green leafy vegetables containing more oxalic acid, etc. with boiling water, so that the food contains oxalic acid, phytic acid and other substances dissolved in water to reduce its content in the food. 6, in the daily diet, if you consume too much fat, fat will be combined with calcium, the formation of calcium soap, known as saponification. The substance is excreted from the feces, so that calcium is lost, therefore, the intake of high-fat foods should be controlled in the daily diet. 7, calcium in an alkaline environment does not dissolve, thus reducing the absorption of calcium utilization; while the acidic environment can keep calcium dissolved state, conducive to calcium absorption. Vitamin C, citric acid, etc. can make the intestinal pH drop, favoring the absorption of calcium in the intestine. 8, in the daily diet, if the intake of too much oligosaccharides, such as table sugar, desserts, etc., it will consume the calcium in the body, thus reducing the calcium content in the body. 9.Children who are excessively nervous or depressed and lack of exercise may suffer from calcium deficiency even if they have sufficient calcium intake in their daily diet, therefore, they should create a good and relaxing atmosphere for their children in their life, especially during meals. 10. Correct your child’s poor eating habits such as partial eating and vegetarianism, and strive to achieve a balanced diet. Here we need to remind parents: children’s calcium supplementation is not more than necessary, too much calcium for children can lead to premature ossification, hindering and affecting height development. At the same time, for children who take calcium supplements for a long time, the blood and urine calcium will be higher than normal, resulting in hypercalciuria and kidney stones, which are hard, irregular and numerous, thus affecting the health of the kidneys. Comparatively speaking, it is safer to take calcium from diet.
