What elements does the human body need?
Sun Zongyan's arrangement in Liaocheng was completed in September 2020 +0 1. The last revision was in June, 20021.3.6438.
There are 35 kinds of essential elements for human body, arranged according to the periodic table of elements. The first is "hydrogen" and the last is "iodine". If 15 kinds of unnecessary but small amount of harmless "lanthanides" are added, the human body needs 50 kinds of elements.
(Red and bold two @ @ fonts are important elements; Blue italics with @ are required elements; The style of black songs is not bold and unnecessary; Bold bold with exclamation point! Harmful, the more exclamation points! ! ! The greater the harm. )
(The first number is the element serial number, followed by the element name, followed by the chemical symbol of the element in brackets)
There are always 35 kinds of essential elements for the human body, and if they are missing or more, they will get sick. )
1. Hydrogen (H) H)@@ constitutes the most basic element of human body, accounting for about 10% of the whole body weight. Hydrogen is contained in water. Drink water regularly, and your body will not be short of hydrogen. You don't need to replenish it deliberately, just drink water.
2. Helium (He) is the lightest inert gas, which is nontoxic and tasteless and has no influence on human body.
3. Lithium (Li)@ Lithium is an essential element for human body, which can improve human hematopoietic and immune functions. Everyone needs 0. 1 mg, which can affect people's mood. If they have, they will be happy, if not, they will be depressed. Sexual dysfunction, shortened life expectancy, and even suicide or crime. Eggs, milk, fish, potatoes and vegetables all contain lithium, and traditional Chinese medicines such as lily and albizzia bark contain more lithium.
4. Yes! ! Beryllium is not an essential element for human body, but it is toxic, but it can be excreted when ingested occasionally and will not accumulate in the body.
5. Boron (B)@ Boron is an essential element for human body. Organic boron contained in plants is beneficial to human body. Boron can increase bone density, accelerate bone healing, enhance muscle function and improve brain response. Boron deficiency can lead to hypertension and arthritis. It requires 1 ~ 2mg per day, but inorganic boron is harmful to human body. Foods containing more boron include soybeans, raisins, almonds, peanuts, pine nuts, hazelnuts, red dates, papaya and honey.
6. Carbon (C)@@ is the most basic element of human body, accounting for about 18% of the whole body weight. It is an important part of food. As long as you eat food, your body will not lack carbon. Lack of carbon will make you hungry and want to eat. If you have food in your stomach, you won't be short of carbon.
7. Nitrogen (N)@@ is the most basic element in protein, accounting for about 3% of the whole body weight. People need 50 grams of protein every day. If people are short of nitrogen (no matter what protein is, its nitrogen content is 6.25%), they will feel greedy and want to eat meat.
8. Oxygen (O)@@ is the most basic element of human body, accounting for about 65% of the whole body weight. It exists in water and is absorbed by breathing. Human hypoxia is often caused by environmental reasons, such as poor ventilation, high altitude and too humidity. Then there are problems with the lungs and trachea. The lack of oxygen in human body is mainly due to poor breathing, which has nothing to do with food.
9. Fluorine (F)@ Fluorine is an essential element for human bones and teeth. Without it, you will get dental caries and need 0. 1 mg every day. Eating too much is not good, and your teeth will turn yellow. Foods rich in fluorine include fish, shrimp, kelp, laver, jellyfish, tea and mineral water.
10.Ne (ne) Ne is an inert gas, which is not found in human body, and it has no effect on human body if inhaled occasionally.
1 1. Sodium (Na)@ is an essential element for human metabolism, accounting for about 0. 15% of body weight. Salt contains, the human body needs 6 grams of salt every day, but it is best not to exceed 10 grams. The best salt is bamboo salt, which is rich in trace elements, followed by raw sea salt, and the worst is.
12. Magnesium (Mg)@ Mg is an essential element for human body, and each person needs 350 mg. Magnesium deficiency will reduce blood calcium and cramp. In severe cases, there will be osteoporosis, memory loss, insanity and muscle weakness. Plants contain magnesium, and the two foods containing the most magnesium are laver and sea cucumber (1000 or more). Pine nuts, hazelnuts and watermelon seeds also contain more magnesium (more than 400, which means milligrams per100g, the same below), and the contents of bananas, beans, mushrooms and sesame seeds are also quite high (about 300).
13. Aluminum (al)! Aluminum is an element harmful to human body. The main causes of Alzheimer's disease are fried dough sticks, vermicelli, vermicelli and puffed food.
14. Silicon (Si)@ Si is an essential element for human body, which will gradually decrease with age. Lack of silicon is prone to cardiovascular diseases, organ atrophy and skeletal deformities. Everyone needs 20 mg, but you must eat it, but you can't inhale it. Inhaling silicon-containing dust makes people get silicosis. Silicon exists widely in the epidermis of plant seeds. Rice and white flour do not contain silicon, but bran and rice bran contain silicon. Only seeds eaten with skin contain silicon, such as corn, beans and other miscellaneous grains, peeled sweet potatoes, potatoes, lotus roots and so on. And metasilicic acid in natural mineral water also contains silicon.
15. Phosphorus (P)@@ is the most important element in human metabolism, an important component of bones, teeth and brain, and an important genetic material. It participates in all life activities. Phosphorus and calcium should have a certain proportion, children and adolescents need 1g/ day, adults need 0.7g/ day, kelp, laver, beans, nuts and so on.
16. Sulfur is the most important element in human metabolism and exists in all protein. The content of human hair, skin and nails is the highest, and garlic, scallion, onion, cabbage, radish, nuts, beans and cereals contain the most sulfur. Sulfur can resist cancer, prevent blood coagulation, scavenge free radicals, resist aging and expel lead. Can prevent diabetes and hepatitis.
17. Chlorine (Cl) is an important element in human activities, accounting for about 0. 15% of body weight. Chlorine can keep water in the body and maintain acid-base balance, and it is the main component of digestive juice in the stomach. Chlorine can introduce carbon dioxide from the body into the blood, and salt contains carbon dioxide. Without salt, people will be weak, extremely tired and turn white prematurely. Eating salt can supplement chlorine. But chlorine is toxic and can't be inhaled.
18. Argon (ar) is an inert gas slightly heavier than air, which is not found in human body, and air accounts for 0.93%. Inhaling a small amount has no effect on human body.
19. Potassium (K)@@ Potassium is an important element necessary for human activities. There is potassium in human cells and sodium outside; Chlorine, potassium and sodium are the three most important elements to maintain the acid-base balance of human body. Vegetables and fruits contain a lot of potassium. Potassium deficiency can lead to dizziness, arrhythmia, vomiting, diarrhea, muscle weakness, spasm and heart failure. Specifically, bananas contain the most potassium in food, and raisins, potatoes, meat, milk, cheese, wax gourd and oranges contain more potassium. However, drinking and eating sugar will accelerate the discharge of potassium in the body, resulting in potassium deficiency, so try to eat less such acidic foods.
20. Calcium (Ca)@@ Calcium is an important element that constitutes bones and teeth. It is the most abundant metal in human body, with 99% in bones and teeth and 65,438+0% in blood. Calcium participates in the functions of more than ten systems such as immunity, nerve, endocrine, digestion, circulation, exercise and reproduction, and participates in the whole process of life evolution and life movement. Calcium deficiency osteoporosis, easy to fracture, calcium deficiency leg cramps in the blood, normal human body needs 800 mg every day. Eating meat and drinking bone soup cannot supplement calcium, because most of the calcium in mammals is water-insoluble calcium phosphate in bones. The top four calcium supplements in food are sesame sauce, shrimp skin, cheese and kelp. In addition, black beans, eggs and milk also contain more calcium. Meat not only contains less calcium, but also leads to osteoporosis, because the human body accelerates the excretion of calcium in order to maintain the acid-base balance in the body.
2 1. Scandium (Sc) Scandium is a rare earth element, which is not an essential element for human body. A small amount is harmless and a large amount is toxic.
22. Titanium (Ti)@ Ti is an essential element for human body, but only organic titanium dissolved in water can be absorbed by human body. Titanium can strengthen physical fitness and resist many diseases. This is a kind of bio-friendly metal. Titanium can balance blood pressure and regulate blood lipid and blood sugar. Anti-aging, whitening effect, anti-cancer Can improve muscle motor function. Generally, foods contain less titanium, and only Lycium barbarum, Astragalus membranaceus and Glycyrrhiza uralensis from Gansu, Ningxia and Qinghai are rich in organic titanium.
23. Vanadium (V)@ trivalent vanadium is an essential element for human body, which needs 65438 0.5 μ g/day, but human body can only absorb trivalent organic vanadium dissolved in water. Organic vanadium has many functions, such as promoting the growth of bones and teeth, promoting hematopoietic function, lowering blood sugar, lowering blood lipid, balancing blood pressure, improving human immunity and so on. But inorganic vanadium is toxic, such as vanadium trioxide (V2O3), vanadium pentoxide (V2O5), vanadium trichloride (VCl3) and ammonium metavanadate (NH4VO3). The higher the price (not the price, but the valence), the greater the toxicity! ! . Foods containing organic vanadium include: cereals, beans, meat, chickens and ducks, fish, shellfish (high content in shells), mushrooms, celery, cucumbers, kelp and so on.
24. Chromium (Cr)@@ trivalent chromium is an important element necessary for human body. Normal young people have 6 mg, but with the increase of age, the trivalent chromium in the body is less and less, and it is less than 1 mg after 50 years old. Trivalent chromium is a longevity factor, which participates in human glucose metabolism, can prevent arteriosclerosis and hypertension, and can resist cancer. Lack of trivalent chromium can lead to cardiovascular disease and diabetes, and adults need 75 micrograms a day. At present, trivalent chromium deficiency is the main cause of hypertension and diabetes. But hexavalent chromium is extremely toxic! ! . Foods containing trivalent chromium include: brown sugar, animal liver, apple peel, banana peel (you can eat it without soaking in water or cooking it), licorice produced in Inner Mongolia, whole wheat flour, potatoes with skins, sweet potatoes with skins, corn, red dates, nuts and so on.
25. Manganese (Mn)@ Mn is an essential element for human body, which can promote bone development, participate in the metabolism of protein, fat and sugar, improve the utilization rate of protein, and maintain the normal function of brain, and has the functions of anti-aging, anti-oxidation, cancer prevention, anti-cancer and anti-anemia. Manganese deficiency can lead to Alzheimer's disease. It makes people slow down, their memory declines, and their movements are uncoordinated. The absorption rate of manganese is only 10 ~ 15%, and the requirement of normal people is 2.5 ~ 5 mg/day. Foods rich in manganese are: walnut, pepper, pepper, star anise, malt, rice bran, sunflower seeds, potatoes, mushrooms and animal liver.
26. Iron is an essential element in human blood. The reason why blood and muscles are red is the color of organic iron, and ruddy complexion is also a sign that there is no iron deficiency. Iron can make blood and muscles carry oxygen and participate in the whole process of human metabolism. Iron participates in hematopoietic function, and iron deficiency can lead to anemia. However, the most abundant iron compound in nature is trivalent iron (Fe2O3, that is, rust) that cannot be absorbed by human body. The human body can only absorb bivalent iron, and it depends on eating animals and plants to supplement iron, but excessive iron can lead to cirrhosis or cancer! ! It is easy to take too much iron preparation, but it is generally not excessive to eat iron-containing food, because the human body can selectively absorb it. The best food for iron supplementation is pig blood, chicken blood and duck blood. Or the heart, liver and kidney of an animal. Jujube and auricularia auricula are the best blood-enriching plants, followed by sesame paste, brown sugar, mushrooms, kelp and walnut kernel. Spinach, shepherd's purse, bitter herbs, amaranth, rape and celery are also supplemented with iron, and peaches, apricots, plums, cherries and raisins can also be supplemented with iron.
27. Cobalt (Mo)@ Cobalt is an essential element for human body, but it only exists in animals. Vitamin B 12 contains cobalt. If the human body lacks cobalt, it will suffer from giant cell anemia, or loss of appetite, muscle weakness, or abnormal bone development, such as hyperosteogeny or disc herniation or dislocation. The total cobalt content in adults is 65438 0.5mg, in bones, 65438 04%, 0.265438 0mg, in muscles, 43%, 0.65mg, and in other soft tissues, 43%, 0.65mg. Organic cobalt will be adsorbed on albumin after entering human body, and will flow to the whole body with blood. Foods rich in cobalt are: animal liver and kidney, especially sheep liver, sheep kidney, deer liver and deer kidney. Secondly, crab meat, oysters and mussels also contain more cobalt. Only red dates, purple grapes and persimmons are a little bit in fruits, and other fruits and vegetables rarely contain cobalt.
28. Nickel (Ni)@ Nickel is an essential element for human body, which almost participates in the whole process of life activities. The consequences of nickel deficiency in human body are very serious, ranging from diabetes and fatty liver to anemia, cirrhosis, uremia, renal failure, and even abnormal phospholipid metabolism in severe cases. What the human body needs is organic nickel. There is more nickel in plants than in animal food. Among the plant foods, there are loofah, mushroom, eggplant, onion and so on. However, the nickel content of meat and seafood in animal foods is slightly higher, such as chicken, mutton, beef, crucian carp, yellow croaker, shrimp and shellfish. But too many people will get cancer if inorganic nickel enters the human body! ! .
29. Copper (Cu)@ Copper is an essential element for human body. Copper deficiency increases the brittleness of bones and blood vessels, which is easy to fracture and cerebral hemorrhage, and also causes mental retardation, brain atrophy, osteoporosis, baldness and vitiligo. The foods with the richest copper content are: animal liver (2500? G/ 100g), sesame (1680), spinach (1350), soybean (1300), taro (1290), black bean (/kloc-. But too much inorganic copper in the body will be poisoned! ! .
30. Zinc (Zn)@@ Zinc is the most essential element for human body. It participates in the whole process of human metabolism, and the repair of human tissues is inseparable from zinc. It is called "flower of life" and is the source of human strength. When the human body is rich in zinc, it is lively and active, and when it is deficient in zinc, it is lazy and easy to sit. Zinc deficiency in young people leads to decreased sexual desire, oral ulcers, blurred vision, rough skin and even anemia, while zinc deficiency in middle-aged and elderly people leads to dull taste, loss of appetite and decreased resistance, and is prone to various diseases and even cancer. However, what the human body needs is water-soluble organic zinc. The content of zinc in food is: liver, kidney and whip of animals, oyster, sea cucumber and shrimp skin in seafood. Generally speaking, animal foods have high zinc content and high absorption rate. Plant food contains relatively little zinc and its absorption rate is relatively low. Plants contain zinc: Chinese cabbage, soybean, white radish, rice (coarse), wheat, whole wheat flour, millet, corn flour, corn, sorghum flour, lentils, potatoes, carrots, purple radish, radish tassels, pumpkins, etc. Rice and white flour do not contain zinc. All kinds of inorganic zinc are harmful to human body! ! .
3 1. gallium (Ga)@ organic gallium has anticancer and bone strengthening effects, and can prevent and treat Kaschin-Beck disease. Wild ganoderma lucidum contains gallium, which will be poisoned if ingested in large quantities, and renal failure will occur if ingested seriously! ! .
32. Germanium is a magical longevity element. Germanium can resist cancer, balance blood pressure, resist aging, prevent arteriosclerosis, treat chronic hepatitis, prevent leukopenia, and treat osteoporosis and rheumatoid arthritis. The germanium content of wild ganoderma lucidum produced in Tibet and Qinghai (especially Kunlun Mountain) is the highest, followed by wild ganoderma lucidum produced in Yunnan-Guichuan (western Sichuan, not eastern Sichuan). Mushrooms also contain a small amount of germanium, which is a resurrection element, but artificially cultivated Ganoderma lucidum contains very little germanium. It should be noted that taking too much artificially extracted germanium preparation will cause renal failure! ! ! .
33. Arsenic (As) Arsenic is not an essential element for human body, but the main component of arsenic (As2O3). However, arsenic in the natural environment will inevitably enter the human body with food and water. If the balance of payments is balanced, there will be no adverse effects. A small amount of arsenic can also promote protein's metabolism, enhance human immunity and prevent skin aging, but excessive arsenic can cause people to die of skin cancer or poisoning! ! ! (For example: Wu Dalang in Water Margin).
34. Selenium (Se)@@ Selenium is an essential element for human body and is known as the "king of anticancer". The daily requirement of adults who are "heart protectors" is 100 microgram, but 72% of the land in China is deficient in selenium, including the three major grain producing areas of Northeast China, Shandong, Shanxi, Henan, Hebei and Jiangsu, which makes 95% of the people in China deficient in selenium. But people who consume more than 400 micrograms a day may be poisoned! ! . Appropriate amount of selenium can improve human immunity, resist oxidation, delay aging, repair cells, improve oxygen carrying capacity of red blood cells, prevent and treat cardiovascular diseases, stomach diseases, diabetes, thyroid diseases, skin diseases, detoxify, protect eyes and prevent cancer. Selenium is insoluble in hydrochloric acid and cannot be absorbed by human body after eating selenium powder. Only selenium in plants can be absorbed by human body. Selenium-enriched foods (definitely related to the origin) include: sea cucumber, sesame, garlic, mushrooms, shellfish, squid, sea crab, scallop, hairtail, yellow croaker, lobster, pig heart and kidney, shrimp skin and shrimp skin.
35. Bromine (Br)@@ Bromine is a very important essential element for human body. It can help human body to resist many diseases by participating in all life activities. It used to be thought that bromine had nothing to do with human body. It took Dr. Billy Hudson of Vanderbilt University 30 years to realize how important bromine is in 2009. All seafood contains bromine, such as kelp, laver, hairtail, yellow croaker, shrimp skin, prawn, squid and sea crab, but terrestrial plants contain less bromine. But inorganic bromine invades the human body and will be poisoned in large quantities! ! .
Krypton (Kr) Krypton is an inert gas, which is more than twice as heavy as air. Generally, it has no effect on human body, but isotopes are radioactive.
37. Rubidium (Rb)@ Rubidium is an essential element for human body. Rubidium will gradually decrease with age in animals and increase with age in plants. Rubidium can protect the patency of cardiovascular and cerebrovascular diseases, and can treat diseases of nervous system, cardiovascular system, urinary system and senile cataract. Rubidium also has anti-cancer and anticancer effects. Elderly people suffer from Alzheimer's disease due to lack of rubidium, and women will have habitual abortion due to lack of rubidium. Rubidium-containing foods include: shrimp skin, small marine fish, small marine crab, small squid, shrimp, suckling pig, sheep fetus and other young animals; Scutellaria barbata, Hedyotis diffusa and Placenta Hominis (human placenta) contain more rubidium.
38. Strontium (Sr)@ Strontium is an essential element for human body. 99% of strontium is in bones and teeth, and 1% is in blood. Strontium deficiency can cause metabolic disorder, and at the same time, it can cause extreme fatigue, sweating, skeletal retardation, osteoporosis, hypertension and even cancer. Animal foods generally do not contain strontium, only sea cucumber, shrimp skin, eggs and milk contain strontium, while plant foods generally contain strontium. Strontium-rich foods are: sea cucumber, hawthorn, red dates, black sesame seeds, seaweed, soybeans, lettuce, wheat (referring to whole wheat instead of flour) and millet. In addition, mineral water also contains strontium (this is the most important indicator of mineral water).
39. yttrium (y)! ! Yttrium is a rare earth element, which is toxic. The human body does not need it and generally does not invade the human body.
40. Zirconium (Zr) is not an essential element and has little influence on human body. But too much is also harmful.
4 1. Niobium is an essential element for human body. Niobium is a kind of biological metal, and it is easy to get sick without it in the body. But it can only absorb organic niobium dissolved in water. Niobium can strengthen the body and resist many diseases. Niobium can balance blood pressure and regulate blood lipid and blood sugar. Anti-aging and anti-cancer General foods contain less niobium, and only Lycium barbarum produced in Gansu and Ningxia and Ganoderma lucidum produced in Panzhihua, Sichuan contain more organic niobium. But excessive intake of inorganic niobium is also harmful! ! .
42. Molybdenum is an essential element for human body. Molybdenum can prevent cancer, balance blood pressure, prevent dental caries and kidney calculi, resist aging, prevent arteriosclerosis and Keshan disease, treat chronic hepatitis, prevent leukopenia, and treat osteoporosis and rheumatoid arthritis. Shortsightedness, myocardial infarction, iron deficiency anemia, growth retardation, mental retardation, Kaschin-Beck disease, esophageal cancer. Foods rich in molybdenum include: animal viscera, meat, whole grains, wheat germ, eggs, leafy vegetables and yeast. Specifically, foods with high molybdenum content are: soybeans, lentils, radish seedlings, brown rice, beef, mushrooms, grapes and vegetables. But inorganic molybdenum will be poisoned when it enters the human body! ! .
43. Technetium (Tc) Technetium is an artificial element, not an essential element for human body. A small amount is non-toxic and a large amount is toxic.
44. Ruthenium (ru) is a platinum group element. Ruthenium is not an essential element for human body, and its shell content is very small, and its oxides are toxic.
45. Rhodium (Rh) is a platinum group element, and ruthenium is not an essential element for human body. Hard shell content is very small, and a small amount is harmless to human body.
46. Palladium (Pd) is a platinum group element, while ruthenium is not an essential element for human body. Hard shell content is very small, and a small amount is harmless to human body.
47. Silver (Ag)@@ is an element that is very beneficial to human body. Drinking water from a silver cup is beneficial to the human body and has a strong bactericidal effect. General antibiotics can kill 6 kinds of bacteria, up to more than 20 kinds, and a very small amount of silver ions can kill 650 kinds of bacteria. Food soup in a silver cup or bowl can be preserved for a long time. Silver can promote wound healing. Dai people put silver bowls in water tanks, and the water in the tanks can be eaten raw without boiling. Dai women wear silver belts, not bucket waists, but snake waists. Silver can prevent the growth of bacteria, soothe the five internal organs, calm the mind, stop palpitations and eliminate evil spirits. All silver and silver compounds are non-toxic to human body. Generally, food contains less silver, so using silver tableware or wearing silver jewelry can make people healthy.
48. cadmium (Cd) ! Elements harmful to the human body will make people lifeless, and the less in the human body, the better. Cadmium in some rice exceeded the standard.
49. Indium (In) Indium is harmless to human body. According to mouse experiments, as long as it does not exceed 1%, it will not cause disease.
50. Tin (Sn)@ is an essential element for human body, which can enhance physical fitness and resist many diseases. Tin plays an important role in various physiological activities and maintaining human health. Tin can resist tumor and inhibit the formation of cancer cells. Tin can promote the synthesis of protein and nucleic acid, which is beneficial to the growth and development of the body; It can promote tissue growth and wound healing and participate in energy metabolism. Lack of tin in human body will lead to abnormal metabolism of protein and nucleic acid, hinder growth and development, especially in children, and even lead to dwarfism in severe cases. Foods rich in tin include chicken breast, beef, lamb chops, rye, lobster, corn, wheat flour, black peas, broad beans, mung beans, sesame seeds, sunflower seeds, mushrooms, beets, cabbage, coffee, honey, peanuts, milk, bananas, hawthorn and garlic.
5 1.Sb！ ! ! Antimony is an element harmful to human body. When antimony invades the human body, people will suffer from many diseases.
52. Tellurium (Te) Tellurium is not an essential element for human body. It doesn't matter if it is missing. If the compound exceeds 1 mg, it will be poisoned.
53. Iodine (I) I) @@@ Iodine is an essential element for human body. If it is lacking, it will cause coarse neck disease, and pregnant women with iodine deficiency will have brain damage. Iodine is an important component of human thyroid hormone. However, iodine deficiency or iodine excess will do harm to human body. The function of iodine is to promote the decomposition of substances in the body and produce heat and energy. In terms of growth and development, it can promote the growth of bones, muscles and sexual function for children. The development and growth of nervous system must involve iodine in the secretion of thyroid hormone.
Foods rich in iodine are seafood, such as kelp, seaweed, shellfish, marine fish, etc., with the highest iodine content; Followed by eggs, milk and meat; However, grains, vegetables and fruits have the lowest iodine content. Normal people contain about 30 mg (20 ~ 50 mg) of iodine; Too much and too little will make you sick.
(Iodine is the last element necessary for human body, arranged by element serial number)
Xenon (Xe) is an inert gas, which is more than twice as heavy as air. The air is scarce and generally has no effect on the human body.
55. Cesium (Cs)! ! Cesium 133 is not an essential element for human body. Cesium 134 and cesium 137 are radioactive and harmful to human health.
56. ba! ! Barium is a toxic element, but barium meal uses barium sulfate insoluble in water and fat, which is harmless to human body.
Lanthanide elements: Lanthanide elements include 17 from the 57th element La, plus the 39th element Y and the 2nd element Scandium. Lanthanide elements are not essential elements for human body, and their effects on human body are: except yttrium (Y)! ! And scandium (sc)! !
