Calcium: the key to bone and tooth development
The daily calcium intake of infants and young children is 300-500 mg. For babies, calcium can promote the development of the baby's bones and teeth. Calcium deficiency affects the baby's height and easily leads to rickets. In addition, it is also easy to cause the baby's enamel development to cause dental caries.
For infants and young children, milk and milk products are the best calcium supplements, not only high in calcium, but also easy to be absorbed by the baby. In addition, soybeans and soy products, eggs, pork bones, fish and shrimp, peanut butter, sesame sauce, enoki mushrooms in vegetables, radishes, fungus, etc. are all good sources of calcium. If the baby drinks milk every day, and the daily diet adds some calcium-rich foods such as soy products or fish and shrimps, the baby will basically not lack calcium.
Pay special attention to the winter, because there are fewer opportunities to get in the sun, and vitamin D is easy to lack, which often leads to calcium deficiency in the baby. But note that this is not the lack of calcium in the food intake, but the result of the lack of vitamin D. Therefore, in this special situation, you should pay attention to taking your baby out to sunbathe, so as to relieve the baby's calcium deficiency.
Iron: an essential component for hemoglobin synthesis
The daily iron intake of infants and young children is 1 mg per kilogram of body weight. Iron is an essential component for the synthesis of hemoglobin, and iron deficiency anemia can easily occur if the baby is iron-deficient. At present, iron-deficiency anemia is a relatively common nutritional problem for children in our country and requires special attention.
For infants and young children, breast milk is the best iron supplement. Although the content is not high, the absorption rate is as high as 50%, so it is best to insist on breastfeeding. Animal blood and liver are the best calcium supplements. The iron content is high, and the absorption rate is as high as 11%-22%. In addition, iron content such as lean meat, fish, corn, kelp, and black fungus is also high, and the absorption rate can reach 5%-10%. Appropriately adding these foods to the diet can also help the baby to replenish iron.
Zinc: a component of more than 200 metal enzymes
Infants and young children need to take 15 mg of zinc every day. Zinc is a component of more than 200 metal enzymes in the human body. It is also an activator of many metal enzymes. It participates in growth and development, tissue regeneration and immune processes. It also directly affects taste and the function of oral epithelial cells. If the baby is zinc deficient, it will easily lead to symptoms such as growth retardation, loss of appetite, and pica.
Animal foods are rich in zinc and have a high absorption rate, especially foods such as shellfish, animal liver, and red meat. In addition, dried fruits and cereals also contain a certain amount of zinc. A good combination of these foods in the diet can also prevent babies from zinc deficiency.
DHA: an important component of the brain and retina
Generally speaking, babies between 6 months and 3 years old need to take 100mg of DHA every day, and after 3 years old, they need to take 150mg every day. DHA, again known as the brain gold, has a content of up to 20% in the human cerebral cortex and up to 50% in the retina of the eye. In infants and young children, DHA helps increase the body of brain nerve cells, which is extremely important for the growth and development of brain nerve conduction and synapses, and affects the baby's learning, memory and vision.
DHA is special, only found in fish and a few shellfish foods, so fish is the most ideal food to supplement DHA. At present, modern scientists have extracted high-purity DHA from marine microalgae, and babies can supplement them by using these DHA products.
Vitamin A: Affects the baby's body's antiviral ability
The daily intake of vitamin A cannot exceed 3,500 international units, otherwise it is prone to poisoning. Vitamin A has a great influence on cell growth, eye development and skin health. Lack of vitamin A can easily lead to a decline in the baby's ability to resist the virus and slow growth and development. Special reminder in winter, proper vitamin A supplementation can alleviate dry skin.
Carrots are rich in carotene, which can be converted into vitamin A in the human body. It can be said to be an excellent food for vitamin A supplementation. In addition, pumpkin, spinach, red sweet potatoes, etc. are rich in vitamin A, which can be converted into vitamin A by the human body. In addition, vitamin A contained in animal food can be directly used by the human body. Appropriate combination of such foods in the diet can help the baby to supplement enough vitamin A.
Vitamin C: Improve the body's immunity
The intake of vitamin A in infants and young children is about 55 mg per day. Vitamin C participates in the growth of human teeth and bones, can prevent scurvy, can help babies keep their gums healthy, prevent infection of abrasions, and promote their healing. In addition, it can effectively strengthen the baby's immune system and help the baby resist the attack of influenza.
Vegetables and fruits are the main sources of vitamin C. Among them, foods such as cherries, guava, red pepper, and persimmon have the highest vitamin C content. A balanced and regular intake of vitamin C is very important for babies. Mothers should prepare foods rich in vitamin C for babies!
