Vitamins, also known as vitamins, are, in popular terms, substances that sustain life, are a class of organic substances necessary to maintain human life, and are also important active substances for maintaining human health.
Then let’s take a look at the various vitamins related to the human body.
Vitamin A is retinol, which is a fat-soluble vitamin. It plays an important role in vision, growth, reproduction, and bone development. Vitamin A can maintain the normal growth, differentiation, proliferation and keratinization of epithelial cells and enhance the resistance to disease. Knocking on the blackboard!!! The lack of vitamin A will be dry and rough on the skin, and the limbs will have a keratotic papule of the conical follicle, night blindness, dryness and softening of the cornea. Because natural vitamin A is only found in animal foods, it has the highest content in animal liver, egg yolk and liver oil, followed by some red yellow green leafy vegetables and fruits such as apricot, mango and persimmon.
Vitamins are also a fat-soluble vitamin, a derivative of steroids. It has an anti-caries effect in physiology, so it is also called anti-caries vitamin. When vitamin D is deficient, adults are prone to osteomalacia, and children are prone to rickets. The general food vitamin D content is not rich. Foods with a high content include marine fish, fish oil from eggs and sea fish, and liver. However, excessive vitamin D supplementation can cause poisoning, which is characterized by thirst, inflammation of the eyes, itching of the skin and so on.
Vitamins are also called tocopherols and are also fat-soluble vitamins. Its best source is vegetable oil (such as corn oil, soybean oil, safflower oil). Wheat germ and nuts also contain large amounts of tocopherol. In addition to its reproductive function, vitamin E’s physiological function is also a highly effective antioxidant for the skin, which improves immune response, prevents aging, and improves skin elasticity and reduces gonadal atrophy. Vitamin E Chinese people have ample supply of vitamin E. The amount of vitamin E stored in adult tissues is quite large, and vitamin E deficiency is rare. However, if there is a serious lack of vitamin E in the long-term, blindness, dementia and arrhythmia may occur.
Vitamin K, also known as blood clotting vitamins, promotes blood clotting. Mainly from green vegetables and some oils (such as soybean oil, rapeseed oil, olive oil), the amount of vitamin K required by the human body is very small, but it is essential to maintain normal blood coagulation and reduce massive bleeding during the physiological period. It can also prevent internal bleeding and hemorrhoids. People who often have nosebleeds should take vitamin K from natural foods.
Vitamin b1 is also known as thiamine or anti-neuritis vitamins or anti-beriberi vitamins. Coarse grains, beans, peanuts, lean pork, liver, kidney, heart, and yeast are rich in vitamin b1. Vitamin b1 protects the nervous system and promotes gastrointestinal motility and appetite. Vitamin b1 deficiency, also known as beriberi, is a disease of people who are characterized by anorexia, weakness, ease of closure, symmetrical progressive polyneuritis, myocardial insufficiency with edema and muscle weakness.
Vitamin b2, also known as riboflavin, is involved in biooxidation and energy metabolism in the body. It also has antioxidant activity. Riboflavin is found in animal and plant foods such as milk, eggs, all types of meat, cereals, root vegetables and fruits. The cause of riboflavin deficiency is insufficient supply, such as eating white rice, not eating rice soup and vegetable soup, not giving dairy products after weaning, changing eating habits, improper cooking, etc.; riboflavin deficiency is the body’s nuclear The deficiency of flavin occurs in a syndrome of scrotal inflammation, glossitis, cheilitis and angular cheilitis.
Vitamin B5, also known as pantothenic acid and per-polyacid, is an indispensable ingredient for maintaining normal hair color, so most of it is used to treat white hair. The main use is calcium pantothenate.
Vitamin b6, also known as pyridoxine, is a water-soluble vitamin. Vitamin b6 is a component of certain coenzymes in the human body and is involved in various metabolic reactions, especially in relation to amino acid metabolism. Vitamin B6 is an indispensable nutrient for the body, which is good for improving immunity and preventing skin cancer and bladder cancer. Also used to treat skin diseases such as acne, rosacea, seborrheic dermatitis, wrinkle skin disease, etc. Vitamin b6 is derived from animal liver, meat, whole grains, green leafy vegetables, soybeans, mushrooms, garlic, and some fish. Its lack of lesions can cause skin and nerves.
Vitamin b12 (cobalamin) is the only vitamin containing metal that has important physiological functions. There are two main reasons: as a cofactor of methyltransferase, it participates in the synthesis of proteins and amino acids in the body, ensuring the normal development of infants and young children. In addition, it also protects the transfer and storage of folic acid in cells and is an indispensable vitamin for the nervous system. Vitamin b12 is found in animal foods, and its rich sources are animal viscera, shellfish and mollusks, skimmed milk powder, seafood and egg yolk. Lack of vitamin b12 in the body can cause anemia, nervous system and skin mucosal lesions.
Vitamin C is a water-soluble vitamin widely found in fresh fruits and vegetables. The body cannot synthesize vitamin C and is supplied externally. Vitamins can promote the formation of connective tissue and collagen, and play an important role in maintaining the normal function of teeth, bones, muscles and blood vessels. It can also promote wound healing, increase resistance to disease, and promote the decomposition of histamine. Certain anti-allergic effects; can also enhance iron absorption and folic acid metabolism, and have certain value for the prevention and treatment of nutritional anemia. Scurvy is a vitamin C deficiency disease, which is caused by a chronic lack of vitamin C. It is characterized by hyperkeratosis of follicles, gingivitis and mucous membrane bleeding.
Folic acid, also known as vitamin b9, is a water-soluble vitamin. It has the effect of promoting the maturation of young cells in the bone marrow. The lack of folic acid in humans can cause megaloblastic anemia and leukopenia, which is especially important for pregnant women. Folic acid deficiency, which produces related metabolic disorders, produces megaloblastic anemia, skin, facial, and another torso, scaly papules, and plaques on the extremities, and a series of clinical symptoms such as seborrheic dermatitis-like changes. Orange juice, dark green leafy vegetables, asparagus, strawberries, bananas and beans (canola and lentils) are rich in natural folic acid. The liver, kidney, yeast and wheat germ are also rich in content.
Niacin is also known as vitamin b3, also known as niacin, an anti-skin disease factor. It is one of the 13 kinds of vitamins necessary for the human body. It is a water-soluble vitamin and belongs to the vitamin b family. Niacin has a strong effect of dilating peripheral blood vessels and is clinically used for the treatment of headache, migraine, tinnitus, and inner ear vertigo. Niacin is a vitamin drug, and nicotinamide is collectively called vitamin pp. It is used for anti-pellagra and can also be used as a blood-swelling drug. If it is deficient, it can produce pellagra, which is characterized by dermatitis, glossitis, enteritis, psychosis and peripheral neuritis. The study also found that vitamin b3 can reduce percutaneous water loss and repair the skin barrier.
Protein malnutrition, known as malignant malnutrition, is protein-energy malnutrition. It refers to the lack of protein, but there is a relatively sufficient amount of calorie intake, the child’s weight is 60% to 80% of normal body weight, accompanied by edema and hypoproteinemia, with edema, dermatitis, hair pigmentation, irritability, emotion A disease characterized by apathy, fatty liver and glossitis. Protein deficiency is due to insufficient supply in the diet and low nutritional quality.
Biotin is also known as vitamin H and vitamin b7. It is a water-soluble vitamin. It is essential for the synthesis of vitamin C and is essential for the normal metabolism of fats and proteins. It is a nutrient necessary to maintain the natural growth, development and normal functioning of the human body. Biotin is a savior of the bald family. It not only prevents the hair from falling and the top of the head, but also prevents the common white hair of the modern people. It also plays an important role in maintaining skin health, maintaining the normal functioning and growth of skin and hair, reducing eczema and dermatitis symptoms. It also improves skin metabolism, prevents rough skin, prevents seborrheic dermatitis and acne, and is promising for anti-acne cosmetics. Biotin is widely found in natural foods, while yeast, egg yolk, liver, some vegetables, beans and nuts have relatively high levels of biotin. Biotinase deficiency is a congenital metabolic deficiency disease.
Essential fatty acid
Essential fatty acids are essential for life activities of the body, but the body itself cannot synthesize polyunsaturated fatty acids that must be supplied by food. Lack of body can cause skin and other diseases.
Enteropathic acral dermatitis
The disease is a rare hereditary zinc deficiency, which is characterized by triads: acral dermatitis, alopecia and diarrhea. The rash is distributed at the extremities, that is, on the face, hands, feet and anus, and the genital area, which has been considered to be a specific disease-type skin marker of zinc deficiency.
Non-hereditary zinc deficiency
This disease, also known as acquired zinc deficiency, is a zinc deficiency disease caused by many other causes besides hereditary AE. Red meat and shellfish are the best sources of zinc, and the germs of cereals are also rich in zinc.
Iron is one of the essential elements that make up the human body. Iron deficiency affects the health and development of the human body. The biggest impact is iron deficiency anemia. Iron is mainly derived from animal meat, internal organs and blood, while red mushrooms, hairy vegetables, black fungus, pig liver and blood, duck blood, turkey liver, beef, clove fish, Scutellaria, peanut kernel, walnut, bran and other foods are A good source of iron for the human body.
Selenium acts as a catalytic component in enzymes or proteins, so the biological function of these proteins is also the biochemical function of selenium, in anti-oxidation, protecting cell membranes and organelle membranes, muscle nutrition, growth and development, liver function, thyroid function, immunity and Prevent tumors from playing a role. There is a clear relationship between Keshan disease and selenium deficiency, which occurs in women in the growing period and children after weaning to preschool. The main features of this disease are myocardial lesions, marked enlargement of the heart, cardiac insufficiency and arrhythmia, muscle pain, and muscle. Weakness with elevated muscle enzymes. We can get selenium from cereals, meat, milk and other foods in our daily lives.
The disease is a disease characterized by an increase in plasma carotenoids and an excessive amount of carotene in sweat causing yellowing of the skin, namely carotene skin. Excessive intake of carotene-rich foods, fruits, and beverages made from them. A large number of carotenoids can be used to treat certain diseases for a long time.
Lycopene is one of the non-vitamin A protocarotenoids. The main source of lycopene is red food tomato and tomato products, which account for 67% of the total. Others include carrots, beets, greens, herbs, broccoli, and spicy. Beans, many fruits,
(such as watermelon) and berries. Excessive consumption of the above foods, especially vegetarians and heterophiles, causes plasma lycopene to be too high. The skin has a reddish or red color change. Once symptoms appear, stop eating red food such as tomatoes, and the symptoms can gradually subside.
