The human body is composed of 80 elements. According to the content of elements in the human body is different, can be divided into macro elements and trace elements in two categories. Usually accounted for more than 1/10000 of the total weight of the body element, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, called the constant element; all of the total weight of the body below the 1/10000 elements, such as iron, zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, known as trace elements (iron also called semi trace elements). The content of trace elements in the human body is really very little, such as zinc accounted for only thirty-three of total body weight percent. Sixty iron only parts per million.
Although the content of trace elements in the human body is not much, but with the human survival and health, vital role in people's life. Their intake of excess, deficiency, imbalance or deficiency will cause varying degrees of human physiological abnormality or disease. The most prominent effect of trace elements and is closely related to life, just like a match head size or less amount can play great role in physiology. Worth noting is that these trace elements typically must directly or indirectly by soil supply, but most people often can not be obtained through diet enough trace element. According to scientific research, so far, has been confirmed the essential trace elements related to the human health and life are of 18 types, namely, iron, copper, zinc, cobalt, manganese, chromium, selenium, iodine, fluorine, nickel, vanadium, molybdenum, tin, silicon, boron, strontium, rubidium, arsenic. Each of these trace elements have their special physiological function. Despite their content in the body is tiny, but they to maintain some decisive The new supersedes the old. is the body of the necessary. Once the lack of these trace elements necessary for human body, will present the disease, and even life-threatening. At present, it is about 30% of the disease directly is a trace element deficiency or imbalance. Such as zinc deficiency can cause eye, mouth, anus or redness, papules, eczema of vulva. And if iron is one of the main component of hemoglobin, iron deficiency can cause iron deficiency anemia. Foreign had reported: the body contains iron, copper, zinc reduced the total, can weaken the immune system (disease resistance force), lower resistance, contributing to bacterial infection, and the infection of the higher mortality. Trace elements in disease resistance, cancer prevention, prolong life and other aspects also plays a very important role.
Trace elements: vanadium, manganese, iron, cobalt, copper, zinc, selenium, iodine and other. Then, each trace element is what kind of physiological function in human body? We introduce the following:
Calcium is the main component of bones and teeth. Calcium also has a great effect on the nervous system, while reducing the content of calcium in the blood, neuronal excitability, have muscle pumping wrestling. Calcium can also help blood coagulation.
Phosphorus is an important component in the body enzyme, nuclear protein, brain phospholipids and bones.
Iron is the manufacture of hemoglobin and other iron materials indispensable element.
Copper is the main raw material for a variety of enzymes.
Sodium is the elements needed for soft tissue contraction.
Contraction of potassium and calcium balance on myocardium are important.
Magnesium can promote the phosphatases, constitute beneficial bone; but still maintain the nervous excitement, lack of convulsions phenomenon.
Fluoride can prevent dental caries and senile osteoporosis.
Zinc is a lot of metal components of the enzyme or enzyme activator, diminished sense of taste, poor appetite, anorexia and dermatitis can children lack.
Selenium Keshan disease, heart failure, nervous system dysfunction and selenium deficiency related.
The lack of iodine, can have a goiter, mental retardation, physical and sexual organs stop symptoms.
Manganese content in vivo for adult 12~20mg. Lack of time can be decreased glucose tolerance, brain function decline, middle ear imbalance and other symptoms.
In addition, also need to introduce two kinds of toxic metal.
Aluminum: can cause low blood calcium, ADHD and joint disease. Lead: anomalies can cause behavioral and neural system. We should avoid contact with them, in order to avoid damage to the body.
