How does a 5-year-old child get the healthiest calcium supplement, and what calcium agent is the best?

The best calcium preparation absorbs 40%, that is, calcium carbonate. For example, calcium gluconate absorbs 9%, calcium phosphate 23%, calcium lactate 32%, calcium chloride 23%, calcium citrate 30%, and milk calcium 3 1%. Among them, calcium gluconate, calcium lactate, calcium citrate and milk calcium belong to organic calcium, which is easy to absorb, but the content is small. Other inorganic calcium is irritating to the stomach, but the content is large. Choose according to the child's situation.

Third, refined calcium gluconate tastes too sour, so you must choose high-purity calcium carbonate, such as Jingu calcium tablets. Long Mu Zhuanggu Granule contains a high amount of lead, so it is not recommended to take calcium supplement now. In addition, it is best to take calcium between meals, so that calcium can be better utilized by the body, and taking calcium between meals is easy to affect the absorption rate of calcium. Avoid putting calcium in milk, rice soup or porridge. Phytic acid in food will affect the absorption of calcium, leading to a decline in the absorption of calcium in the body. Taking cod liver oil supplements vitamin D while supplementing calcium, but taking it at the same time does not mean taking it at the same time. You should eat separately, preferably in the morning and evening. It should be noted that summer does not make up, winter makes up, and spring and autumn makes up as appropriate.

Calcium-containing foods mainly include:

1, milk, yogurt, cheese and other dairy products.

2. Bean products such as tofu and soybean milk.

3, shrimp skin, kelp, seaweed, marine fish, fish bone meal and other aquatic products.

4. Other foods: egg yolk, sparerib soup, lotus root powder, root plants, sesame seeds, hawthorn and so on.

Make big bone soup. Wash the bought big bones, break them or break them, put them in a pot and blanch them in cold water, add the bones, boil them, skim off the floating foam, add onion, ginger and cooking wine, and stew them for a long time on low heat. This is a very good calcium supplement food, such as bone soup, steamed egg soup and so on. Shrimp skin and tofu are high in calcium. When cooking fish or ribs, put some vinegar and simmer with low fire for a long time, so that the calcium in fish bones and ribs is fully dissolved, and calcium is most easily absorbed with protein. Tofu and fish are stewed together, and VD contained in fish promotes the absorption of calcium in tofu; Tomatoes scrambled eggs, and VC in tomatoes promoted the absorption of calcium in eggs. Plant foods, such as spinach and some vegetables, will affect the absorption of calcium. Because vegetables contain oxalate, phosphate and other salts, which combine with calcium to form polymers and precipitate, thus hindering the absorption of calcium. If you blanch spinach and other vegetables with boiling water before eating them and destroy oxalic acid in them, the absorption of calcium will be better. Oily foods can't be eaten together with calcium supplementation, because fatty acids will be generated after oil decomposition, which will combine with calcium to form milk lumps, which are not easily absorbed by the intestine, and calcium will eventually be excreted with the stool, which will affect the absorption of calcium.

In addition, when the dietary calcium content is low, its role in promoting calcium absorption is particularly important. This is because it can enhance the expression of CaBP in intestinal epithelial cells and contribute to calcium transport in cells.

Substances that reduce intestinal pH can promote calcium absorption: lactose in diet can reduce intestinal pH, which is beneficial to calcium absorption.

Substances that increase the solubility of calcium can promote the absorption of calcium: lactose in diet can form soluble small molecular substances with calcium, which is beneficial to the absorption of calcium. Appropriate amount of protein in the diet can also promote the absorption of calcium, because some degradation products of protein in gastrointestinal tract, such as lysine, tryptophan and arginine, can form soluble calcium salts with calcium and increase the absorption of calcium. Generally, when protein's intake is from lack to appropriate level, the absorption of calcium increases, but when protein's intake exceeds it.

After this appropriate level, there is no further effect. Appropriate phosphorus-containing diet: It is generally believed that the ratio of calcium and phosphorus in the diet is 1.0~ 1.3, which is beneficial to calcium absorption. If the phosphorus content is too high, it will form insoluble calcium phosphate with calcium and inhibit the absorption of calcium.
