Zinc mainly exists in marine products and animal offal, and other foods contain little zinc-children's favorite water, staple food and eggs contain little zinc, and vegetables and fruits contain little zinc.
Lean meat, pork liver, fish, egg yolk, etc. Oysters have the highest zinc content. According to laboratory tests, the zinc content in animal foods is generally high, and the zinc content in each100g of animal foods is about 3-5mg, and amino acids produced after animal protein decomposition can also promote the absorption of zinc. Zinc content in plant food is less. Every100g of plant food contains about 65438 0 mg of zinc. There are beans, peanuts, millet, radish and Chinese cabbage with high zinc content in various plant foods.
The zinc content per100g of food is about:
3.8 grams of lean pork; 4 mg of pig liver; Chicken liver 5 mg; Egg yolk 3.4 mg; Kelp 3.2 mg; Fish and shrimp 8 mg.

If zinc deficiency is serious or the above foods are deficient, you have to turn to drugs for help.
Zinc sulfate: It was first used in clinic, but it has many defects. Long-term use will cause serious digestive tract reactions, such as nausea, vomiting and even gastric bleeding.
Zinc gluconate: it belongs to organic zinc, and it has only slight gastrointestinal discomfort, which can be eliminated by taking it after meals. Can be dissolved in juice for babies to drink.
Zinc yeast: Ideally, it is a pure natural product produced by bioengineering technology. The combination of zinc and protein has high bioavailability and good taste, which children are more willing to accept.
Children should pay attention to zinc supplementation: According to research, if children aged 2-6 are slightly deficient in zinc, they will often be lower in height and weight than normal children, and in severe cases, dwarfism may occur. Clinically, children with zinc deficiency often have symptoms such as loss of appetite, recurrent oral ulcers, yellow hair and even food addiction.
In addition, zinc deficiency in children can also affect the synthesis of immunoglobulin, thus making children's immune function decline and vulnerable to infectious diseases. Therefore, for the healthy growth of children, smart mothers must pay attention to supplementing zinc to their children. So, how to supplement zinc for children?
1. Children should supplement zinc and insist on breastfeeding: the zinc content in human milk is high. Breast-fed children are less likely to be deficient in zinc. Although milk contains a lot of zinc, it is not suitable to be absorbed by human body. All clever mothers must insist on breastfeeding.
2. Children should pay attention to adjusting their diet when supplementing zinc: a smart mother should give her children some foods rich in zinc, such as oysters, livestock and poultry meat, eggs, fish, seafood, cheese, oats and peanuts. Oysters, in particular, have the highest zinc content, and the zinc content per 100 g of oysters is 100 mg, which is called "a good product for zinc supplementation". In addition, because monosodium glutamate can promote the discharge of zinc in the body, children should try to reduce the intake of monosodium glutamate.
3. Zinc supplementation for children. Pay attention to calcium intake: calcium will affect the utilization rate of trace elements such as zinc and iron in the body. Therefore, smart mothers should not give their children too much calcium, and it is best to supplement calcium between meals to reduce the influence of high calcium on zinc absorption in the diet.
4. Children can take zinc products to supplement zinc: Children with obvious zinc deficiency should take zinc products such as zinc selenium treasure under the guidance of a doctor. In addition, milk is not conducive to the absorption of zinc, and zinc products should not be eaten with milk.
● Pay attention to the seasonality of zinc supplementation.
In summer, due to the high temperature, children's poor appetite and less food intake, zinc intake will inevitably decrease, and the zinc loss caused by heavy sweating should be higher than the other three seasons.
● Beware of drug interference
Many drugs can interfere with the results of zinc supplementation. For example, tetracycline can combine with zinc to form a complex, while vitamin C can combine with zinc to form an insoluble complex. Similar drugs include penicillamine and folic acid. Try to avoid these drugs when supplementing zinc.
● The food should be all right.
Crude fiber such as leek, bamboo shoots and oats, bran sugar and grain germ contain more phytate. Both crude fiber and phytate can hinder the absorption of zinc, so the diet during zinc supplementation is more suitable and meticulous. In life, pay attention to cultivating your baby to develop good eating habits without partial eclipse and picky eaters, and ensure a rich and balanced nutritional intake; Pay attention to diversification in the arrangement of recipes and eat more foods rich in zinc to avoid zinc deficiency in the baby. Foods containing zinc are mostly animal foods, such as oysters, lean meat, pork liver, fish and eggs. In addition, soybeans, corn, millet, lentils, potatoes, pumpkins, cabbages, radishes, mushrooms, eggplants, walnuts, pine nuts, oranges and lemons also contain more zinc.
● Don't forget to supplement calcium and iron.
The latest research shows that supplementing zinc with two mineral elements, calcium and iron, can promote the absorption and utilization of zinc and accelerate the recovery of the body, because the three elements have synergistic effects.
