In addition, pediatric patients need to pay attention to help bone growth. First, the amount of calcium absorption directly affects the growth of bones and affects a person’s growth. First of all, calcium absorption is related to age, the younger the calcium absorption rate is higher, the general absorption rate of calcium is 60% for infants, 20% for adults, and even less for the elderly, and the absorption of calcium is only 25% at the age of about 18, so the sooner you take calcium, the better. Second, increase the intake of calcium in the diet, milk contains more calcium components, more absorption, drink more milk can increase the intake of calcium. Third, more sunshine, can make the skin 7-dehydrocholesterol into vitamin D3, to help the absorption and utilization of calcium, it is recommended that the morning before nine o’clock in the evening after five o’clock each sunshine half an hour is appropriate. Fourth, eat foods rich in lactose, such as milk. It can make the PH value of the intestine fall, which is conducive to calcium absorption. Fifth, the right amount of protein has certain amino acids that help calcium absorption. Sixth, a high-fat diet, mixed meals with slightly more fat, in the intestine to stay relatively longer, the intestine to absorb calcium will be relatively longer, can absorb more calcium. Seventh, a diet low in phosphorus, too much phosphorus will affect the absorption of calcium, generally processed foods, such as sausages, ice cream, cola and other drinks, are high phosphorus food, should eat less.
