What are the reference values ​​for trace elements for infants?

For parents who want to do trace element tests for their babies, it is necessary to understand the reference values ​​of trace elements for babies so that they can understand which trace elements their children are lacking. So what are the reference values ​​for trace elements for infants? Next, this article will introduce you to the reference values ​​of trace elements for infants. Friends who want to know more about this aspect can take a look! Please see the detailed introduction below.

1. Reference value of zinc element: 76.5～170.0umol/L

Symptoms of zinc deficiency: loss of appetite, loss of taste, and even pica; slow growth and development, short stature; recurrent dermatitis, eczema, oral ulcers, and difficulty healing after skin and mucous membrane trauma; intellectual disability, etc.

Prevention and treatment methods: Foods rich in zinc include seafood, such as oysters, scallops, scallops, etc.; nuts also contain high zinc, such as walnuts, almonds, sesame seeds, etc. Zinc supplements include zinc gluconate and licorice zinc.

2. Reference value of copper element: 11.8～39.3umol/L

The human body's demand for copper is very low, and the Chinese diet is very rich in copper, so copper deficiency rarely occurs. On the contrary, copper often exceeds the standard. Too much copper can cause damage to the liver and brain.

Prevention and treatment methods: Animal viscera contain high levels of copper, and foods cooked in copper-containing utensils also contain high levels of copper.

3. Reference value of iron: 7.52～ 11.8mmol/L

Iron is the most abundant essential trace element in the human body. It is stored in hemoglobin in the form of ferritin. The function of iron is very important. Iron deficiency can lead to decreased learning ability, decreased memory and concentration, listlessness, irritability, and decreased resistance to infection. Children may complain of dizziness, headache, and fatigue.

Prevention and treatment methods: Foods rich in iron include animal livers, such as chicken liver, pork liver, etc.; soy products are also high in iron and easy to absorb, such as soy milk and tofu; egg yolks are very high in iron, but the absorption rate is slightly lower, and it can also be considered one of the iron supplements.

4. Reference value of calcium: 1.55～2.65mmol/L

Prevention and treatment methods: Milk, soy products, and nuts are rich in calcium; cod liver oil promotes the absorption and utilization of calcium; get more sun exposure.

5. Reference value of magnesium: 1.12～2.06mmol/L

Magnesium has similar physiological functions to calcium. The reason why we rarely hear about the element "magnesium" is that the Chinese people's living habits and dietary structure are very rich in magnesium, and Chinese people are not prone to lack of "magnesium"

6. Reference value of lead element: 0～100μg/L

Prevention and treatment methods: Automobile exhaust, pencils, low-quality toy furniture paint and wall paint, secondhand smoke, batteries, preserved eggs, printer ink, etc. contain high levels of lead. Try to reduce your baby's exposure to these things. Fruits rich in vitamin C, such as kiwi, orange, and grape, are beneficial for the excretion of lead; supplementing calcium and zinc is also beneficial for the excretion of lead.

The above is an introduction to the reference values ​​of trace elements for infants. I believe that after reading the above introduction, you will have a very good understanding of the reference values ​​of trace elements for infants. We also know the importance of these trace elements and how to prevent and treat trace element deficiencies. I hope this knowledge can be helpful to everyone.
