What are trace elements? What effect do trace elements have on human body?
Those elements whose content in human body is extremely small and less than 0.0 1% of body weight are called trace elements.
Quantitative elements. Although the content of trace elements in human body is very small, it is harmful to human health.
Play an important role. As components of enzymes, hormones, vitamins and nucleic acids, they participate.
The metabolic process of life. In a sense, trace elements are more harmful to the body than vitamins.
More needed. At present, there are more than 20 trace elements, such as iron, iodine, copper,
Trace elements such as manganese, zinc, diamond, chromium, selenium, salt, fluorine, silicon, tin and vanadium are related to the life of organisms.
Activities are closely related.
(1) plays a specific activation center role in the enzyme system.
Trace elements keep the subunits of enzyme protein together or act on the enzyme.
The chemical substance binds to the active center of the enzyme. Iron, copper, zinc, diamond, manganese, aluminum, etc.
Gene linked with coordinate groups or molecules, such as hydrophobic groups, colloidal group, isopyrazolyl groups, pressure groups and hydroxyl groups.
Combine to form a complex, which exists in the side chain of protein.
(2) It plays a specific physiological role in hormones and vitamins.
Some trace elements are components and important active parts of hormones or vitamins.
Without these trace elements, the corresponding hormones or vitamins cannot be synthesized.
The physiological function of the body is bound to be affected. Such as iodine in thyroid hormones.
Diamonds in vitamin B 12 are all such trace elements.
(3) the role of transport elements
Some trace elements can transport common elements in the body. If iron is blood.
The carrier of oxygen in hemoglobin cannot synthesize hemoglobin without iron, and neither can oxygen.
Transportation, tissue cells can't metabolize, and the body can't survive.
(4) regulating the osmotic pressure of body fluids and acid-base balance
Trace elements in body fluids, combined with plasma of potassium, sodium, calcium and magnesium, can be adjusted.
It can reduce osmotic pressure and body fluid pH, and maintain normal physiological functions of human body.
(5) affecting nucleic acid metabolism
Nucleic acid is the carrier of genetic information, which contains quite a lot of chromium, iron,
Trace elements such as zinc, manganese, copper and nickel will affect the generation of nucleic acid.
Thank you. Therefore, trace elements play an important role in heredity.
(6) Anti-cancer and anti-cancer effect
Some trace elements have certain anti-cancer and anticancer effects. Such as iron and selenium.
Intestinal cancer is resistant to orange agent; Magnesium is effective in treating malignant lymphopathy and chronic leukemia.
Use; Zinc has anti-cancer effect on esophageal cancer and lung cancer; Iodine has effects on thyroid cancer and breast cancer.

Vitamins are a group of nutrients with similar physiological functions and nutritional significance. They are essential substances for human growth and reproduction. Although the content in food is very small, they definitely exist, because they can't be synthesized in the human body and can't be fully stored.
Vitamins are divided into fat-soluble and water-soluble. Fat-soluble vitamins include vitamins A, D, E, K, etc. Water-soluble vitamins include vitamins B 1, B2, PP, B6, B 12, C, etc. When the vitamin supply in the diet is insufficient or lacking, it will produce corresponding vitamin deficiency, such as lack of vitamin A, which will lead to night blindness, dry eye and dry skin, which will hinder the growth and development of children; Lack of vitamin d is prone to rickets and rickets; Lack of vitamin B 1 susceptibility to beriberi; Lack of vitamin B2 is prone to glossitis; Lack of vitamin B 12 is prone to pernicious anemia; Lack of vitamin c is prone to scurvy; Lack of vitamin PP may lead to pellagra.
People who live on food and vegetables and eat less meat tend to lack vitamins A, D and B2. In northern winter and spring, vitamin C deficiency is easy to occur due to the lack of vegetable varieties.
Different seasons have different eating habits: eat more carrots to prevent vitamin A deficiency; The light time should be increased to supplement rickets caused by insufficient supply of vitamin D in diet. Animal foods such as viscera are rich in vitamin B2; Bean sprouts are rich in vitamin C. In addition, vitamins A and D can be strengthened in oil. However, it must be noted that vitamins A and D are aliphatic vitamins. If you take too much uncontrolled, it will be stored in the liver and poisoned.
Vitamin A. Maintain normal vision and prevent night blindness; Maintain the health of epithelial cells; Promote growth and development; Enhance resistance to infectious diseases; Prevention and treatment of dry eye.
Vitamin D regulates calcium and phosphorus metabolism, promotes absorption and utilization, and promotes bone growth.
Vitamin E. Maintain normal reproductive capacity and normal muscle metabolism; Maintain the integrity of the central nervous system and vascular system.
Vitamin k stops bleeding. It is not only the main component of prothrombin, but also can promote the production of prothrombin in the liver. Vitamin k deficiency in children
Vitamin B 1 Maintain the normal functions of circulation, digestion, nerves and muscles; Regulating gastrointestinal function; Coenzymes forming decarboxylase participate in sugar metabolism; It can prevent beriberi.
Vitamin B2. Also known as riboflavin. Nucleoprotein is a component of many important coenzymes in the body. These enzymes can transfer hydrogen during the metabolism of substances in the body, and are also essential substances for the metabolism, energy utilization and composition of protein, sugar and fatty acids. Can promote growth and development, and protect eye and skin health.
Pantothenic acid (calcium pantothenate). Anti-stress, anti-cold, anti-infection, prevent the toxicity of some antibiotics, and eliminate postoperative abdominal distension.
Vitamin B6. It plays an important role in protein metabolism. Treat neurasthenia, vertigo, atherosclerosis, etc.
Vitamin B 12. Anti-fatty liver, promote liver to store vitamin A; Promote cell development and maturation and body metabolism; Treat pernicious anemia. Vitamin B 13 (lactic acid clear).
Vitamin B 15 (pantothenic acid). It is mainly used to resist fatty liver and improve the oxygen metabolism rate of tissues. Sometimes used to treat coronary heart disease and chronic alcoholism.
Vitamin B 17. Highly toxic. Some people think it can control and prevent cancer.
P-aminobenzoic acid. Among the B vitamins, it is one of the newly discovered vitamins. Can be synthesized in the human body.
Inositol. One of the B vitamins, like choline, is a lipophilic vitamin.
Vitamin C. Structure connecting bones, teeth and connective tissue; It has adhesion to capillary wall cells; Increase antibodies and enhance resistance; Promote red blood cell maturation.
Vitamin p.
Vitamin PP (nicotinic acid) plays the role of transferring hydrogen in the process of cell physiological oxidation and has the function of preventing and treating furuncle.
Folic acid (vitamin m). Antianemia; Maintain the normal growth of cells and the function of immune system.
Vitamin T helps blood coagulation and platelet formation.
Vitamin u. It plays an important role in treating ulcers.
Vitamin A mainly exists in milk, dairy products, meat, chicken, fish, animal liver, carrots, celery, spinach, bitter gourd, oranges, hawthorn and other foods; Walnut, sesame, grain, wheat, meat, fish, mushrooms, vegetables and fruits have higher vitamin B content. Generally, vegetables, fruits and beans contain a lot of vitamin C; Vitamin D can be obtained from animal foods, such as liver, milk, egg yolk, roe, vegetable oil, yeast and mushrooms. Vitamin E mainly exists in vegetable oil, green vegetables, animal organs, beans, egg yolk, melons and fruits, lean meat, sesame seeds and peanuts. Green vegetables and animal livers are rich in vitamin K.
Or you can directly take various vitamin tablets and various vitamin-rich drinks under the guidance of a doctor.
In daily life, as long as the diet is reasonable, not picky eaters, not partial eclipse, not eating "refined" food, trace elements in the body can be guaranteed.
