Everything in the world is composed of elements, of course, the human body is no exception. At present, there are more than 100 known elements, the human body can be found in more than 60 kinds of elements of the “trace”, some of which may be only temporarily into the body, and does not participate in the body’s metabolic activities. According to current research, it has been known that there are about 25 kinds of elements are indispensable to the composition of the human body, according to their content in the body, accounting for less than one ten thousandth of the human body weight is called trace elements, including iron, zinc, copper, iodine, fluorine, manganese, molybdenum, cobalt, chromium, selenium, tin, silicon, nickel, vanadium, and the rest of the elements for the macronutrients, such as carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, sodium, chlorine, calcium, magnesium. For the human body, both trace elements and macronutrients are very important. Parents are so superstitious about the role of trace elements that they attribute all of their children’s problems to “what’s missing”? Small babies love to struggle, shaky hands and feet, poor sleep, nail problems, constipation, skin rashes, finger eating, farting, thinness, obesity, short size, freckles and other problems, will be attributed to “trace elements”, all the way to go through all the trouble of registering for a number, the purpose is one, to want to check the trace elements, to see whether these are due to the lack of that called “trace elements”, “trace elements” are very important. “Trace elements are essential micronutrients for the body. Micronutrients, as essential micronutrients, are different from macronutrients such as fats, proteins and carbohydrates, and cannot provide calories to the body. Their role in the human body is to serve as a part of the structure of the body as an important component or as a part of the metabolic reaction of the enzymes or coenzymes needed, and their deficiency will not be felt immediately by the human body, but if they are neglected for a long time, they will definitely affect the human body’s health, and the corresponding manifestations will appear. Some of these manifestations can be defined as a disease, such as iron deficiency causing iron deficiency anemia, iodine deficiency hypothyroidism, but there are many trace element deficiencies that may be difficult to define as a disease, and may be manifested by symptoms that are difficult to explain at present, and those symptoms mentioned above, well, maybe some of them are indeed caused by some trace element deficiencies, but According to the current medical level can not make a clear diagnosis, this situation has a unified diagnosis, called “hidden hunger”, as the name suggests, the body does not feel “hungry”, not because of satiety, but because of nutritional imbalance, or lack of some essential micronutrients. So, micronutrient deficiencies should be taken seriously. Check “trace elements” can know what the body lacks? No! At present, our hospital on the “trace elements” test includes seven elements: calcium, iron, zinc, copper, magnesium, cadmium, lead. Careful children’s shoes will find that these seven elements actually contain macronutrients calcium, magnesium, there are two other above are not mentioned: cadmium and lead, these two are metal elements, is not supposed to appear in the human body, but because of certain unavoidable factors and detected in the blood, but their content is the smaller the better, or else it is an “excess! Otherwise, it is “overdose” or even “poisoning”, which is harmful to the human body. Therefore, at present, there are only three kinds of trace elements that can be detected: iron, zinc and copper. Like calcium in the previous section, the concentration of these elements in the blood can often be kept normal under the regulation of the body’s various regulatory mechanisms, which means that even if the body is really deficient in these elements, their concentration in the blood may also be normal. Often poopers are very happy when they learn that their child’s micronutrients are completely normal, thinking that even though the child has been malnourished, the child is not deficient in anything! I am sorry to tell you that your child may be deficient in everything! Inquiring children will ask: Is there any blood test to know what your child is deficient in? I am sorry to say: no! There is really no need to spend money to make children suffer and adults suffer to go to the hospital specifically to check the “trace elements”, unless, unless, the need for blood tests to check other items, by the way, check trace elements, can satisfy the curiosity of the poops and pussies on the trace elements. But is there a way to make sure your child is not deficient in anything? There is! That is: after your child starts to add complementary foods, you should gradually diversify the types of food, so that every meal is nutritionally balanced!
