Should trace elements be checked? Other than this, nothing else is really necessary

A mother in the background said that the child is going to kindergarten, and the school requires that trace elements must be detected. In order for the child to go to school, she also took the child to take the test. But the test results made her very worried, showing that the child was deficient in zinc and calcium. For this reason, she always felt that she did not feed her children well, which caused the children to lack this and that, which affected their health. In fact, this mother really does not need to blame herself, because many methods for detecting trace elements are not reliable, and the results are not authoritative.

What are trace elements in the human body?

The human body is composed of many kinds of chemical elements, 11 elements account for more than 99.95% of the human body weight, so they are called macroelements, including the familiar carbon, oxygen, and hydrogen that account for more than 95% of the human body weight. , 4 kinds of nitrogen, and potassium, sodium, calcium and other metal elements which account for about 4%-5% of human body weight. There are also some elements below 0.01% of human body weight, these are called trace elements. There are iodine, iron, zinc, selenium, etc., which have been proved to be necessary for the human body, and manganese, silicon, boron, etc., which the human body may need, and fluorine, lead, cadmium, mercury, etc., which the human body needs but are potentially toxic. How little are trace elements in the human body? Their content is only a few grams, and only a few milligrams. But although the amount is very small, it cannot be lacking. Because without them, people will lose their health. For example, iron deficiency will cause dizziness, fatigue, and symptoms of anemia. Of course, it should not be too much. Too much iron will lead to gastrointestinal adverse reactions such as diarrhea. The trace elements in the human body should be within a reasonable range. If you just detect the lack of a certain trace element and start supplementing, it may also cause the child to get sick.

Why is trace element detection unreliable?

For trace element testing, as early as 2013, my country stipulated that it should not be used as a physical examination item, but it did not prevent many places from still requiring it. In 2021, the General Office of the National Health and Medical Commission will issue another notice to change "inappropriate" to "not allowed". There is a difference in one word, but the requirement is clearly put forward: the detection of trace elements cannot be used as a routine item of children's physical examination. The reason for this requirement is that the test is not reliable, and the results of the test are not authoritative. Unreliable reasons, let's start with the detection method. The test is typically done by examining the child's blood, hair, or even clipping the wrist or finger with a device.
  • Blood
This method uses the venous blood or peripheral blood of the child, and the results have a particularly large deviation. Because this method can only measure the content of trace elements in blood, but there are very few trace elements in blood, and more trace elements exist in cells and tissues. Therefore, this method cannot objectively reflect the overall level of trace elements in the human body.
  • Hair
Testing hair is not as good as testing blood. Hair has fewer trace elements, and it can only reflect the content of trace elements within a few weeks, and it is also susceptible to various factors. Effects such as sweat, residual shampoo, etc.
  • Clamping detection
This is even more unreliable, and it can even be said that it is a scam set up by businesses to promote equipment or health care products. The device clips the wrist or finger to collect bioelectrical signals, and cannot measure any data of trace elements in the body at all. Therefore, these detection methods for trace elements seem to be "high-end", but in fact they are not reliable, nor can they be used as a basis for supplementing children with trace elements.

So, how do you know if your child is deficient in micronutrients?

Some parents may be anxious when they see this. The human body cannot lack trace elements, otherwise there will be problems, but the test method is not reliable. How do you know if the child is lacking trace elements? In fact, parents worry too much. Under normal circumstances, with our current living standard, as long as the child is not picky eater, not partial eclipse, has a balanced diet and good digestion, the micronutrient intake from food is sufficient, and no additional supplements are required. If the child has a severe partial eclipse and the gap between the height and weight is too large, you can take the child to a professional hospital for professional trace element testing. What the Health and Health Commission prohibits is "non-diagnostic treatment needs", if it is a diagnosis and treatment need, it can be detected. Professional doctors will make a comprehensive diagnosis based on the test results, other inspection indicators, the child's diet and symptoms, and will give scientific and effective treatment to the symptoms. Therefore, according to national regulations, children do not need to be tested for trace elements when entering kindergartens. If the kindergarten requires, parents can only test in order to allow their children to enter the kindergarten smoothly, but they do not need to care about the test results, and they do not need to follow the results to supplement their children. .
