The role of trace elements

The human body is composed of more than 80 kinds of elements. According to the content of different elements in the human body, can be divided into macro elements and trace elements two categories. All elements that make up more than one ten thousandth of the total body weight, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium and sodium, are called constant elements; Such as iron, zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, known as trace elements (iron, also known as semi-trace elements). The amount of trace elements in the human body is really minimal, such as zinc accounted for only 33% of the total body weight. Iron is only 60 parts per million.

Although trace elements in the human body content is small, but with people’s health and life are closely related to human life plays an important role. Their overdoses, deficiencies, imbalances, or lack of them all cause physiological abnormalities or diseases in varying degrees. The most prominent is closely related to the vitality of life, just as the matchmaker head of the amount of less or less can play a huge physiological role. It is noteworthy that these trace elements usually must be supplied directly or indirectly from the soil, but most people often can not get enough trace elements through diet. According to scientific research, there are 18 kinds of essential trace elements that have been identified to date related to human health and life, that is, iron, copper, zinc, cobalt, manganese, chrome, selenium, iodine, nickel, fluorine, molybdenum, vanadium , Tin, silicon, strontium, boron, rubidium, arsenic and the like. Each trace element has its own special physiological function. Although they are extremely low in the human body, they are essential to sustaining some of the crucial metabolic processes in the body. Once the lack of these essential trace elements, the human body will be sick, even life-threatening. At present, it is quite clear that about 30% of the diseases are caused directly by lack of or imbalance of trace elements. Such as zinc deficiency can cause mouth, eyes, anus or vulva swelling, papules, eczema. Another example is the composition of iron is one of the main components of hemoglobin, iron deficiency can cause iron deficiency anemia. Abroad has been reported: the body of iron, copper, zinc reduce the total, can reduce the immune mechanism (resistance to disease power), reduce disease resistance, contribute to bacterial infection, but also higher mortality after infection. Trace elements in disease resistance, cancer prevention, longevity and other aspects also play a very important role.

Trace elements: vanadium, manganese, iron, cobalt, copper, zinc, selenium, iodine and so on. So, what is the physiological function of each trace element in the human body? We highlight the following:

Calcium is the main component of the skeleton and teeth. Calcium on the nervous system also has a great impact, when the blood calcium content decreased, increased nerve excitability, muscle pumping occurs. Calcium can also help blood coagulation.

Phosphorus is an important component of enzymes, nuclear proteins, cephalin and bone in the body.

Iron is an indispensable element in the manufacture of hemoglobin and other iron-based substances.

Copper is the main raw material of a variety of enzymes.

Sodium is an essential element for soft tissue contraction.

The balance of potassium and calcium plays an important role in the contraction of myocardium.

Magnesium can promote the function of phosphatase, the composition of beneficial bone; can also maintain the excitement of nerves, lack of convulsions occur.

Fluorine can prevent dental caries and senile osteoporosis.

Zinc is a component of many metal enzymes or enzyme agonists, children may appear when lack of taste loss, poor appetite, anorexia and dermatitis.

Selenium heart failure, Keshan disease, nervous system disorders and lack of selenium.

Iodine deficiency, there may be goiter, mental retardation, body and sexual organ development stopped and other symptoms.

Manganese adult body content of 12 ~ 20mg. Deficiency may occur when impaired glucose tolerance, decreased brain function, middle ear imbalance and other symptoms.

In addition, we also need to introduce two kinds of toxic metals.

Aluminum: Can cause hypocalcemia, ADHD and arthrosis in children.

Lead: can cause behavior and nervous system abnormalities. Usually we should be less exposed to them, so as not to harm the body.
