The recovery of all things in the spring has gone through a long cold winter, and all creatures are about to start moving. Spring is also a good time for your baby to grow. Moms should seize this opportunity to add enough nutrients to help your baby grow to a higher level.
1, calcium must add vitamin D
Vitamin D should also be added at the same time as calcium supplementation, because vitamin D can regulate calcium and phosphorus metabolism and increase body's absorption and utilization of calcium. If you combine high-calcium foods with foods rich in vitamin D, you will have a multiplier effect. Children's daily supply of vitamin D should be 10 micrograms, such as daily sunshine hours of not less than 2 hours, eat two egg yolks, vitamin D deficiency generally does not appear.
2. Do not take phosphorus-containing calcium supplements
The main elements of bone production are calcium and phosphorus, and the relationship between the two is very close. The calcium and phosphorus that the human body ingest must accord with a certain proportion, if the phosphorus intake is too much, will form the insoluble calcium phosphate excreted. Inevitably lead to the loss of calcium. However, due to the problems of food and water sources, the Chinese people's phosphorus intake has been greatly exceeded. Especially in infants and young children, phosphorus exceedance will lead to a series of serious consequences. Chinese nutrition experts appeal: Do not give infants and young children calcium-containing supplements!
3. Magnesium affects the absorption of calcium
Both calcium and magnesium are divalent ions, and absorption in the human body will have a competitive effect. For infants and young children, the magnesium content in the body can meet metabolic needs through food, and no additional supplements are needed. Magnesium overdose can not only affect the absorption and utilization of calcium, but also cause motor dysfunction. It is recommended not to blindly supplement magnesium containing calcium. .
4, food less salt, is conducive to the absorption of calcium
Recent studies have found that calcium and sodium compete in the reabsorption process in the renal tubules. When the sodium intake is high, the body will reduce the absorption of calcium. The International Health Organization recommends that Chinese people should eat less than 6g of salt per person per day, and infants and young children should be as few as possible. Therefore, it is recommended that families who like to eat salty foods strictly control the intake of salt in children's diet and ensure the absorption and utilization of calcium in children.
5. Effect of Phytic Acid and Oxalic Acid in Food on Calcium
The Chinese are mainly plant foods. Legumes and unfermented flours contain phytic acid; some vegetables (spinach, bamboo shoots, green soybeans, peony root, onions, etc.) contain oxalic acid, which can bind calcium into insoluble substances and affect the absorption of calcium. Calcium should pay attention to these issues.
