What are the elements?

The functions of these elements are detailed as follows:

Iodine is an important trace element for synthesizing thyroid hormone, which acts on target organs through blood, especially liver, kidney, muscle, heart and developing brain. Iodine deficiency and iodine excess are both harmful to health. Iodine deficiency can affect the growth and sexual development of children's height, weight, bones and muscles, and the damage to the brain development and nervous system development of fetuses and infants is irreversible. Excessive iodine can cause poisoning and dysplasia, especially for infants. Clinical data show that long-term intake of excessive iodine can cause acute hyperthyroidism, goiter and, in severe cases, thyroid cancer. Although most people have a high tolerance to iodine, infants may be sensitive to iodine overdose because their physical development is not perfect.

iron. The content of iron in human body is about 4-5g. The function of iron in human body is mainly to participate in the formation of hemoglobin and promote hematopoiesis. The content in hemoglobin is about 72%. Iron is high in spinach, lean meat, egg yolk and animal liver.

copper. Normal adults contain 1-2mg of copper. Its main function is to participate in the hematopoietic process; Enhance disease resistance; Participate in the formation of pigment. Copper is high in animal liver, kidney, fish, shrimp and clam. Fruit juice and brown sugar also have a certain content.

zinc. It plays an important role in many physiological functions of human body. Participate in the synthesis of various enzymes; Accelerate growth and development; Enhance the regeneration ability of traumatic tissue; Enhance resistance; Promote sexual function. Zinc content is high in fish, meat and animal liver and kidney.

fluorine. It is a normal component of bones and teeth. It can prevent dental caries and osteoporosis in the elderly. Foods with high fluorine content include grain (wheat and rye flour), fruit, tea, meat, vegetables, tomatoes, potatoes, carp and beef.

selenium. Adults need about .4 mg per day. Selenium has the functions of anti-oxidation and protecting red blood cells, and it also has the function of preventing cancer. Selenium is abundant in wheat, corn, Chinese cabbage, pumpkin, garlic and seafood.

iodine. Play a physiological role through thyroxine, such as promoting protein synthesis; Activate more than 1 enzymes; Adjust energy conversion; Accelerate growth and development; Maintain the structure of the central nervous system. Iodized kelp, laver, marine fish and sea salt are rich in content.

Trace elements are closely related to human health. Excessive intake, insufficient intake or lack of them will cause physiological abnormalities or diseases in different degrees. The most prominent function of trace elements is closely related to vitality, and only the amount as big as matchhead or less can play a huge physiological role. It is worth noting that these trace elements must be directly or indirectly supplied by soil. According to scientific research, up to now, there are 18 kinds of essential trace elements related to human health and life, namely, iron, copper, zinc, cobalt, manganese, chromium, selenium, iodine, nickel, fluorine, molybdenum, vanadium, tin, silicon, strontium, boron, rubidium, arsenic and so on. Each of these trace elements has its special physiological function. Although they are very small in human body, they are necessary to maintain some decisive metabolism in human body. Once these essential trace elements are lacking, diseases and even life-threatening will occur in human body. It has been reported abroad that the reduction of the total amount of iron, copper and zinc in the body can weaken the immune mechanism (resistance to disease), reduce the ability to resist disease, and promote bacterial infection, and the mortality rate after infection is also high. Trace elements also play an important role in disease resistance, cancer prevention and longevity.

Trace elements are closely related to human health. In recent years, trace elements are considered as a promising new field related to human health and longevity, which has attracted widespread attention from nutrition and medical circles at home and abroad. So, what is the relationship between trace elements and health? Let's take a look at how some trace elements affect human health.

cobalt. It is an important part of vitamin B12. Cobalt plays an important role in protein, fat, carbohydrate metabolism and hemoglobin synthesis, and can dilate blood vessels and lower blood pressure. However, excessive cobalt can cause polycythemia, gastrointestinal dysfunction, deafness and myocardial ischemia.

fluorine. Fluorine is a normal component of human bones and teeth. It can prevent dental caries and osteoporosis in the elderly. However, if you eat too much fluorine, you will get fluorosis and get "dental plaque disease". When the fluoride content in the body is too high, it can also produce skeletal fluorosis and cause spontaneous fractures.

chromium. It can help insulin to play its role, prevent arteriosclerosis, promote metabolism and synthesis of protein, and promote growth and development. But when the chromium content increases, such as long-term inhalation of chromate powder, lung cancer can be induced.

From this point of view, although trace elements are particularly important to human body, too much or too little intake can cause diseases. It is found that many endemic diseases and some tumors are related to trace elements.

In recent years, the medical research on trace elements has been deepened. These seemingly insignificant elements play a decisive role in people's health. Of course, girls can't keep fit without it.

Magnesium is an important source of many enzymes in human body. Although the content of magnesium in human body is very small, without magnesium, people will be mentally exhausted, sallow and emaciated, with rough skin and even unstable mood, and their faces and limbs will tremble. Once girls have the above symptoms, they should check whether magnesium is normal. If magnesium is deficient or low, you can take drugs with magnesium supplement function appropriately. According to research, figs, bananas, almonds, winter melon seeds, corn, sweet potatoes, cucumbers, pearl powder, mushrooms, persimmons, soybeans, laver and oranges are rich in magnesium.

zinc is one of the most important trace elements in human body, mainly concentrated in liver, muscle and skin. When zinc is deficient, it will cause loss of appetite, low immune function, dull eyes, rough skin, easy infection, anemia, decreased vision, dull hair, and even hepatosplenomegaly, which will lead to slow development. Some girls have more facial acne and acne, which is also related to zinc deficiency. Zinc deficiency can also be supplemented with food. Some animal foods, such as oysters, fish, animal liver, meat and eggs, contain a lot of zinc.

Iron contains about 3-5g in adults, of which 6-7% is in hemoglobin. Iron deficiency often leads to anemia, which can not only make girls look inferior, but also bring trouble to the whole body, resulting in dizziness, palpitation, physical decline, memory loss, inattention, low disease resistance and other symptoms, losing the foundation of girls' bodybuilding. Animal blood, animal liver, sesame paste, auricularia auricula, mushrooms, seaweed, bean products, shrimp, sea cucumber, mullet, spinach, soybeans, etc. all contain a lot of iron, which can appropriately increase the food intake.

When the copper content is reduced in the body, it will affect the absorption of iron, lead to the obstacle of iron utilization, and finally lead to iron deficiency anemia. Copper is also closely related to the elasticity and moisture of human skin. When copper is deficient, it will cause girls' dry and rough skin, pale face, decreased immunity and even affect their reproductive function in the future. (Wang Li)
