Trace elements: boron, fluorine, silicon, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, selenium, bromine, molybdenum, tin and iodine (*** 16 kinds).
Iodine is an important trace element in the synthesis of thyroid hormone, which acts on target organs through blood, especially liver, kidney, muscle, heart and developing brain. Both iodine deficiency and iodine excess are 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 lead to poisoning and stunting, especially for infants. Clinical data show that long-term intake of excessive iodine can cause acute hyperthyroidism, goiter, and even thyroid cancer. Although most people have a high tolerance to iodine, infants may be sensitive to excessive iodine because their physical development is not perfect.
Iron. The content of iron in human body is about 4-5g. The role of iron in human body is mainly to participate in the formation of hemoglobin and promote hematopoiesis. The content of hemoglobin is about 72%. Spinach, lean meat, egg yolk and animal liver have high iron content.
Copper. Normal adults contain copper100-200mg. Its main function is to participate in the hematopoietic process; Enhance disease resistance; Participate in the formation of pigment. Copper is high in liver, kidney, fish, shrimp and clam of animals. 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. The zinc content in fish, meat, animal liver and kidney is high.
Fluorine. It is a normal part of bones and teeth. Can prevent dental caries and osteoporosis in the elderly. Foods with high fluorine content include cereals (wheat and rye flour), fruits, tea, meat, vegetables, tomatoes, potatoes, carp and beef.
Selenium. Adults need about 0.4 mg per day. Selenium has antioxidant and protective effects on red blood cells, as well as cancer prevention. Wheat, corn, Chinese cabbage, pumpkin, garlic and seafood are rich in selenium.
Iodine. Play a physiological role through thyroxine, such as promoting protein synthesis; Activate the enzyme above 100; 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 different degrees of physiological abnormalities or diseases.
Cobalt It is an important component of vitamin B 12. 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. Can prevent dental caries and osteoporosis in the elderly. But if you eat too much fluorine, you will get fluorosis and get "dental plaque disease". When the fluorine 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 the human body, too much or too little intake will cause diseases. It is found that many endemic diseases and some tumors are related to trace elements.
In recent years, the research on trace elements in the medical field has been deepened day by day. 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 emotional instability, and their faces and limbs will tremble. Once girls have the above symptoms, it is necessary to check whether magnesium is normal. If magnesium is deficient or low, drugs with magnesium supplement function can be taken 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, dim eyes, rough skin, easy infection, anemia, decreased vision, dull hair, and even hepatosplenomegaly, leading to developmental retardation. Some girls have more facial acne and acne, which is also related to zinc deficiency. Zinc deficiency can also be supplemented by food. Some animal foods, such as oysters, fish, animal livers, meat and eggs, contain a lot of zinc.
The content of iron in adults is about 3-5g, of which 60-70% exists in hemoglobin. Iron deficiency often leads to anemia, which will not only make girls feel inferior, but also bring trouble to the whole body, leading to dizziness, palpitation, physical decline, memory decline, inattention, low disease resistance and other symptoms, losing the foundation of girls' bodybuilding. Animal blood, animal liver, sesame paste, black fungus, mushroom, seaweed, bean products, shrimp, sea cucumber, mullet, spinach, soybean, etc. Both contain a lot of iron, which can increase the food intake appropriately.
When the copper content in the body decreases, 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.
