What are the 72 trace elements in the human body and their functions?

1. Calcium. Calcium (Ca) is one of the most abundant mineral elements in the human body, and the normal function of tissues and organs of various systems of the human body depends on its existence. Calcium is an indispensable and important element for brain neuronal metabolism, which can ensure mental vigor, calm mind, improve people's judgment, and affect people's emotions.

Sufficient calcium can inhibit the abnormal excitation of cranial nerves and keep the person calm. Calcium deficiency can affect nerve conduction, making the excitability of nerves and muscles out of balance, and people will become sensitive, emotionally unstable, and difficult to concentrate. Medical studies have found that the serum levels of calcium, iron, and zinc in patients with neurodeafness are lower than those in healthy people.

Eating calcium is good for human bones.

2. Magnesium. Magnesium (mg). Magnesium calms the central nervous system, helps eliminate tension during menstruation, and reduces psychological stress.

Magnesium deficiency can cause a variety of headaches, including additional symptoms such as photophobia and sound phobia. Magnesium-based medicine (MGSO) is effective in eliminating headache symptoms.

3. Zinc. Zinc (zn). Zinc is an important trace element in the hippocampal gyrus (the hippocampal gyrus is located in the center of the human brain that controls learning and memory activities, and is mainly responsible for the formation and storage of long-term memory), which is related to memory and intelligence.

Breast milk may be more beneficial for the baby's growth, mental development and mental improvement, which is related to zinc absorption.

4. Iron. Iron (Fe). Iron is the most abundant trace element in the human body, mainly in the form of iron porphyrin complexes (heme), which is generally considered to have the greatest effect on respiration.

As the main component of hemoglobin, iron and low-valent iron are easy to convert with each other, and the redox reaction is rapid, making it the material with the best oxygen delivery capacity.

5. Iodine. Iodine deficiency is one of the known causes of intellectual disability in humans. According to surveys, 80% of the more than 10 million mentally disabled people in China are caused by iodine deficiency.

Lack of iodine in food can cause a certain amount of psychological tension and lead to poor mental state. Regular consumption of foods containing iodine can help relieve tension and help you sleep.

6. Selenium. Selenium (Se). Selenium is an essential element in the synthesis and metabolism of thyroid hormones, and when selenium deficiency occurs, it can cause a decrease in thyroid function, which can lead to depression.

Selenium deficiency reduces the body's immune function, which is a characteristic of people with depression.

Selenium is also an essential component of glutathione peroxidase in the body, which is an important antioxidant enzyme that protects the body's nerves and avoids tissue damage, and plays a role in the pathogenesis of mental disorders. Selenium can regulate the mood of depressed patients, relieve depressive symptoms, reduce the pain and suffering, and improve the quality of life.

Trace elements refer to the elements that are less than the content in the human body, there are 70 kinds found at present, mainly obtained from food, including calcium, iron, zinc, selenium, copper, manganese, etc., although trace elements are only one ten-thousandth of body weight, but the lack of them will cause disease or discomfort, and excessive intake will cause poisoning.

Trace elements are mainly involved in the metabolism of enzymes, hormones, vitamins and nucleic acids, not only can catalyze enzymes or constituent enzymes, but also assist in the synthesis of hormones or vitamins, affecting the metabolism of nucleic acids. Deficiency of trace elements can lead to dysfunction of the body, such as zinc deficiency, which can lead to the occurrence of night blindness and even affect male reproductive function.

There are 14 kinds of trace elements that the human body must not lack: iron, iodine, selenium, zinc, copper, cobalt, nickel, fluorine, silicon, manganese, key, chromium, tin, vanadium, etc.

Trace elements mainly rely on stomach digestion and respiratory tract intake, and even some can penetrate through **, now industrial pollution is becoming more and more serious, and has become a trace element intake channel, generally speaking, meat is more trace elements than vegetarian food, and better absorption, seafood and brown rice contain the most, because the trace elements of rice are mainly contained in the germ, but when processing, at least 75% is lost. Basically, the more refined the food, the less nutritious it is.

1.Foods high in iron: Animal offal (chicken liver, chicken heart, beef kidney, pork liver, etc.), cocoa powder, brown sugar, caviar, soybean flour, beef, potatoes, etc.

2.Foods high in iodine: Sea plants (kelp, seaweed, hair cabbage, etc.), yams, fish maw, etc.

3.Foods high in zinc: Beef, pork liver, rice sugar, wheat bran, shrimp, peanuts, squid, shiitake mushrooms, black rice, eggs, fish, watermelon seeds, etc.

At present, there are 14 trace elements that are determined to be beneficial to the human body and must be ingested, including: iron, copper, zinc, manganese, etc. These trace elements play a pivotal role in the body's daily metabolism.

Good health is to ensure the content of various trace elements, if there is a long-term lack of a certain trace element, the body will be abnormal and even produce various diseases.

Trace elements are very important for maintaining human health. If not ingested properly, it can affect the health of the body, and the growth and normal development of children will be affected. Severe deficiencies in trace elements may also lead to other diseases.

For example, the trace element iron has hematopoietic function, and the lack of iron will easily cause various anemias, and the lack of iron in children will hinder development, and the consequences are very serious. Moreover, severe deficiencies in trace elements may also endanger life. Therefore, friends should treat their diet correctly and take in a variety of nutrients to ensure their health.

There are many kinds of essential trace elements for the human body, the more important ones are iron, zinc, copper, fluorine, selenium, cobalt, iodine, trace elements in the weight of the human body below, called trace elements, there are 18 kinds of essential trace elements known to the human body.

Hello, iron is the "boss" among trace elements. It is one of the most abundant trace elements essential for the human body. The human body contains a total of 60% of the total amount of iron, of which 70% is found in hemoglobin.

It is involved in the transport, exchange and respiration of oxygen, and is responsible for transporting oxygen to all corners of the body and excreting carbon dioxide, a waste product produced by tissue cells. When dietary iron intake is insufficient or too much is lost, iron deficiency and even iron deficiency anemia can occur.

There are many, iron, copper, zinc, tin, calcium, and so on.

The so-called trace elements, in environmental geochemistry, refer to more than 60 elements that only account for the components of the earth, and their content is generally between 1 10-8 1 10-88. In the field of medicine, from the perspective of the structure of the human body, those that account for less than 1/10,000 of the total weight of the human body are trace elements. According to the body's need for trace elements, those trace elements that are indispensable for maintaining the normal life activities of the organism, must be ingested through food and have a daily dietary requirement of less than 100mg are called essential trace elements.

The human body is composed of more than 40 kinds of elements, according to the different content of elements in the body, the elements in the body can be divided into two categories: one is a macro element, accounting for body weight, including carbon, hydrogen, oxygen, phosphorus, sulfur, calcium, potassium, magnesium, sodium, chlorine and other 10 kinds, they constitute the body tissue, and play an electrolyte role in the body; The second is trace elements, accounting for about body weight, including iron, copper, zinc, chromium, cobalt, manganese, nickel, tin, silicon, selenium, molybdenum, iodine, fluorine, vanadium and other 14 kinds, although the content of these trace elements in the body is negligible, but can play an important physiological role. There are 8 kinds of essential trace elements for the human body, including iodine, zinc, selenium, copper, molybdenum, chromium, cobalt and iron.

Trace elements are elements whose content in the body is less than 1/10,000 of body weight.

Iron: Iron is the most needed trace element in the human body, 27% of iron is composed of hemoglobin, 3% of iron is composed of myoglobin, and iron is composed of a variety of iron-containing enzymes. Hemoglobin can send oxygen to tissues throughout the body, and myoglobin has a strong binding force to oxygen, which can store part of the oxygen, which can be released when skeletal muscle is hypoxic.

The daily iron requirement is 10 to 18 mg, and if the supply is insufficient, iron deficiency anemia can occur.

Zinc: Zinc is a trace element second only to iron, a component of more than 200 zinc-containing enzymes, and an activator of enzymes, which plays an important role in nucleic acid metabolism and protein synthesis. The daily zinc requirement for infants is 3 5 mg, and for children aged 1 10 years, it needs 10 mg of zinc per day.

Insufficient zinc supply in infants and young children affects growth and intellectual development, as well as taste and immune function, and zinc deficiency is the main cause of anorexia.

Iodine: Iodine regulates heat metabolism in the body and is an important component of thyroxine. Babies need milligrams of iodine per day. If iodine deficiency affects the growth and development of children, causing cretinism or endemic goiter; Iodine poisoning can also occur if too much is ingested.

Copper: Copper is very small in the human body and is an important component of a variety of metalloenzymes in the body, the main function is to promote iron to form hemoglobin, and it is also a cofactor for many oxidases. When the body is deficient in copper, anemia, neutropenia, slow growth, and emotional instability can occur.

Selenium: Selenium is involved in the metabolism of glutathione peroxidase in the body and is an indispensable trace element for muscle metabolism in the human body. Selenium deficiency is predisposed to Keshan disease.
