Bone broth.

Pork leg bones - these are the large bones with a hole in the center to hold the marrow. A better cylinder bone would be the leg bone of the hind leg because the bone is thicker here. The marrow in the bone contains a lot of collagen, which, in addition to being cosmetically pleasing, promotes wound healing and strengthens the body.

The "tube bone" soup not only can't make up for the calcium, but will "hinder the stomach", seriously affecting the child's health and development.

Drinking "tube bone" soup harm: give the child to drink "tube bone" soup, is to take into account the pig bone calcium, that "tube bone" coarse, calcium content is higher, and want to use the fire to put the calcium of the soup. I want to use the fire to stew calcium out to enhance the child's nutrition. In fact, the solubility of the calcium in the bones is very low, and it is very difficult to get the calcium out of the bones by fire.

With the fire, the calcium is not stewed out, but stewed out of the bone marrow fat, the kind of greasy things, let the child eat, seriously affect the digestive capacity. The child's stomach is not good, do not want to eat, but instead caused a nutritional imbalance, more contributed to the lack of calcium.

Different calcium supplements contain different amounts of calcium. Calcium carbonate contains about 40%, calcium acetate 29%, calcium citrate 21%, calcium hydrogen phosphate 15%, calcium lactate 13%, calcium gluconate 9%. Studies have shown that there is not much difference in the pure absorption of a single calcium agent in the body. Calcium carbonate contains the highest calcium, but absorption to consume more stomach acid, easy to cause indigestion in babies; calcium lactate and calcium gluconate are organic calcium, easy to dissolve, suitable for children's calcium supplement.

According to the "Dietary Nutrient Reference Intake Table for Chinese Residents" issued by the Chinese Nutrition Society, the appropriate daily intake of calcium for infants and young children is divided into age groups, 0-6 months is 300 milligrams, 6-12 months is 400 milligrams, 1-3 years old is 600 milligrams. When the intake exceeds this amount and increases further, the risk of toxic side effects increases. If the baby is not deficient in calcium, there is no need to blindly supplement calcium.
