Vitamin is an indispensable nutrient to maintain the normal function of the human body. It is a kind of low molecular organic compound closely related to the metabolism of the human body. It is a component of many enzymes that play an important regulatory role in the metabolism of substances. Although the human body needs little vitamin, it has a great effect. When the body vitamin supply is insufficient, can cause the body metabolism barrier, thus causes the skin function barrier.
Vitamins are divided into fat-soluble vitamins (such as vitamin A, vitamin D, vitamin E, vitamin K, etc.) and water-soluble vitamins (such as vitamin B group, vitamin C, vitamin PP, folic acid, etc.). All kinds of vitamins have unique effects in beauty and skincare.
Vitamin A can maintain the function of skin cells, make the skin soft, tender, wrinkle-resistant and wrinkle-free. Lack of vitamin A can reduce the function of epithelial cells and lead to the decrease of skin elasticity, dryness, roughness and tarnish. Vitamin A is rich in animal liver, cream, butter, carrot, sweet potato, green leaf vegetable, chestnut, tomato, etc.
Vitamin B1 can promote gastrointestinal function, increase appetite, help digestion, eliminate fatigue, prevent obesity, moisturize the skin and prevent skin aging. Vitamin B1 is rich in lean meat, grain, peanut, sunflower, pine, hazelnut and purple garlic. Vitamin B2 has the functions of keeping skin healthy, lightening skin wrinkles, eliminating skin spots and preventing peripheral neuritis. Insufficient supply of vitamin B2 can cause rough skin, wrinkles, seborrheic dermatitis, angular stomatitis, cheilitis, acne, white hair, vitiligo, alopecia areata, etc. Liver, kidney, egg, cheese, mushroom in the red mushroom, pine mushroom, winter mushroom, dried fruit in the almond, vegetables in the golden needle vegetables, alfalfa vegetables rich in vitamin B2 should often be eaten. Vitamin B6 can promote the metabolism of human body fat and nourish the skin; vitamin B1, B2 can promote the metabolism of the skin and make the blood circulation smooth, so it is called “beauty vitamin”. Foods containing vitamin B1 and B2 include animal viscera, fish, oysters, stinky tofu, soybean curd, etc.
Vitamin C can decompose melanin in the skin, prevent pigmentation, prevent chloasma and freckle, keep skin white and tender, and promote wound healing, strengthen blood vessels and bones. Therefore, we should eat foods rich in vitamin C, such as hawthorn, fresh jujube, lemon, orange, kiwi fruit, mango, grapefruit, strawberry, tomato, potherb mustard, cabbage, balsam pear, cauliflower, etc. These foods can not only meet the needs of the human body for vitamin C but also contain a lot of water. They are the best skin moisturizing products for the human body. In addition, fresh vegetables and fruits are also the sources of multivitamin C, which is beneficial for regulating blood circulation, promoting metabolism, protecting skin cells and skin elasticity.
Vitamin D can promote skin metabolism, enhance the resistance to eczema and scabies, and promote bone growth and tooth development. Taking vitamin D can inhibit the formation of skin erythema, treat psoriasis, alopecia areata, skin tuberculosis and so on. When the body lacks vitamin D, the skin is easy to fester. Vitamin D can only be obtained in a small amount from food, and most of it is transformed on the skin by ultraviolet irradiation. The simplest way to supplement is to take the preparation of cod liver oil. But because cod liver oil is composed of vitamin A and D, taking too much can cause poisoning, it is best to take it under the guidance of a doctor. Foods containing vitamin D include liver, COD, flatfish, salmon, sardines, animal liver, eggs and milk.
The role of vitamin E in beauty and skin care can not be ignored. Because the oxidation of human sebum is one of the main causes of skin aging, and vitamin E has antioxidant effect, thus protecting sebum, cell membrane protein and water in skin. It can also promote the regeneration and vitality of human cells and delay the aging process of cells. In addition, it can promote the use of vitamin A by human body, cooperate with vitamin C, protect the health of skin, reduce skin infection, moisturize collagen fiber and elastic fiber in skin, improve and maintain the elasticity of skin, promote the blood circulation in skin, make the skin get enough nutrition and water, maintain the tenderness and tenderness of skin It can also inhibit the formation of pigment spots and senile spots, reduce facial wrinkles and whiten skin, and prevent acne. Therefore, in order to maintain the skin’s fitness and delay aging, we should eat more foods rich in vitamin E, such as pea oil, sunflower seed oil, sesame oil, egg yolk, walnut, sunflower seed, peanut, sesame, lettuce leaf, orange peel, lean meat, milk, etc. In a word, it is very beneficial for human health and skin fitness to take enough vitamin food every day.
Among all kinds of elements in the human body, except for carbon, hydrogen, oxygen, and nitrogen, which are mainly in the form of organic compounds, there are 7 kinds of elements with more contents, such as calcium, magnesium, potassium, sodium, phosphorus, sulfur and chlorine. They are essential elements for life activities, growth and development, and for maintaining normal physiological functions in the body, as well as for human beauty and health. They are called “constant elements.”. Among the various elements that make up the human body, some of them only contain trace or ultra-trace elements in the body, which are called trace elements in nutrition, such as 14 kinds of iron, zinc, iodine, selenium, copper, manganese, cobalt, molybdenum, chromium, nickel, tin, vanadium, silicon and fluorine. They are important components of various hormones, vitamins and nucleic acids in the organism, and they are activators or auxiliary factors of many enzyme systems, which participate in the metabolic process of life substances. These inorganic salts and trace elements also play an important role in beauty and skincare. When the body supply is insufficient, it can cause metabolism disorder in the body, cause skin dysfunction, and affect bodybuilding. Elements closely related to skin beauty and human body beauty include:
It is an important raw material for human hematopoiesis. Iron deficiency in the human body can cause iron deficiency anemia, resulting in a pale face, dull skin, insomnia, forgetfulness, body fatigue, and poor thinking ability. Iron-rich foods include pig liver (and various animal liver), light vegetables, kelp, sesame paste, black beans, black fungus, etc.
Zinc is one of the important components of many enzymes in the human body. It is involved in the synthesis of nucleic acids and proteins in the human body, and its content in the skin accounts for 20% of the total body content. Zinc plays an important role in the development of secondary sexual signs, especially in the “three encirclements” of women. Zinc content in the eye is very high, zinc deficiency people, the eyes will become dull, and even cause vision disorders. Zinc has a unique effect on skin health. It can prevent acne, dry skin and various kinds of hillock diagnosis. If children are lack of zinc, it will seriously affect their growth and development. The foods rich in zinc include oysters, sea cucumber, kelp and other seafood, such as lean meat, walnut kernel, pine nut, hazelnut, onion, garlic, broccoli, mustard, mustard, Chinese toon, amaranth, broccoli, red pepper, agaric, mushroom, preserved fruit, watermelon, preserved apricot, coconut, fresh date, peanut kernel, sunflower kernel, etc.
The elasticity, moistening, and redness of human skin are related to the effect of copper. Copper and iron are important raw materials for hematopoiesis. Copper is also a component of some metal enzymes in the human body. Copper is indispensable for the energy release of tissues, the formation of phospholipids in the nervous system, the synthesis of collagen in bone marrow and the metabolism of skin and hair pigment. Copper and zinc are related to the metabolism of protein and nucleic acid, which can make skin delicate, hair black and bright, make people young and keep fit. Lack of copper in the human body can cause dry and rough skin, dry hair, pale face, weak reproductive function, and reduced resistance. Copper rich foods include animal viscera, shrimp, crab, shellfish, lean meat, milk, soybean, and hard fruit, etc.
The main physiological function of iodine in the human body is to form thyroxine, regulate energy metabolism, promote growth and development, maintain normal nerve activity and reproductive function, and maintain the luster and elasticity of human skin and hair. Iodine deficiency can lead to compensatory hypertrophy of thyroid gland, mental and physical development disorders. The skin is wrinkled and tarnished. Iodine rich foods include kelp, sea cucumber, sea fish, laver, jellyfish, sea rice, razor clam, clam and other seafood.
Selenium is mainly distributed in liver and kidney, followed by heart, muscle, pancreas, lung, gonad, etc. The content of selenium in hair can often reflect the nutritional status of selenium in the body. Selenium is not only an indispensable element for the maintenance of human health and the prevention and treatment of some diseases, but also a strong oxidant, which can protect cells and resist some chemical carcinogens; it can regulate vitamin A, vitamin C and vitamin E, enhance the resistance of human body; it can protect the integrity of visual organ function, improve and improve vision; it can make hair shiny and elastic, Make your eyes bright and bright. Selenium rich foods include wheat, wheat germ powder, millet, corn, sweet potato stem, watermelon seeds, fish, eggs, pods, etc.
Chromium widely exists in human tissues, but its content is very small, and it is an indispensable substance for human body. The contents of bone, skin, fat, adrenal gland, brain and muscle are relatively high. The main physiological functions of chromium are: it has certain effect on the metabolism of nucleoprotein; it can inhibit the synthesis of fatty acids and cholesterol, affect the metabolism of lipids and sugars; it can promote the secretion of insulin, reduce blood sugar and improve glucose tolerance. The most common manifestations of chromium deficiency are arteriosclerosis; the elderly are prone to diabetes and arteriosclerosis due to chromium deficiency; chromium deficiency in pregnancy can cause gestational diabetes; chromium deficiency in normal people can lead to dry skin, increased wrinkles, loss of luster and elasticity of hair. The main food sources of chromium are whole grains, beans, lean meat, yeast, beer, cheese, liver of livestock, brown sugar, etc. Fresh grapes and raisins contain the most chromium, which is called “chromium storehouse”. The finer the food is processed, the less chromium it contains, and the less chromium it contains in refined foods. Therefore, in order to supplement chromium, we should eat more roughage.
The main functions of calcium in the human body are: to participate in the formation of bones and teeth; to maintain the normal metabolism of cells in the body; to participate in the conduction of excitability of muscles and nerves in the body; to maintain the normal coagulation of blood in the body; to maintain the normal osmotic pressure of the internal and external fluid of capillaries; to activate a variety of enzymes. The lack of calcium in the human body can lead to rickets in children, such as the square skull, chicken breast, tooth defect, etc.; osteoporosis and osteomalacia can occur in adults, nervous tension, irritable temper, restlessness, etc. Calcium-rich foods include shrimp skin, milk, sesame paste, milk, beans, and their products, large yellow croaker, fishbone, animal bone, black sesame, lentil, cowpea, Maodou, potherb mustard, etc.
The main physiological function of phosphorus in the body is to form one of the main components of bones and teeth, to participate in the formation of nuclear protein in the body, and to participate in the metabolism of protein, fat and sugar in the body. B vitamins (vitamin B1, vitamin B6, vitamin PP, etc.) can be active and play the role of coenzyme only after phosphorylation; they can form a variety of enzymes in the body and maintain the acid-base balance of the blood, etc. Lack of phosphorus in the body can also lead to rickets, bone calcification, etc., affecting body building. The food rich in phosphorus includes soybean, black bean, red bean, broad bean, peanut, sesame, walnut, egg yolk, chicken, lean pork, lean mutton, crab, rice, millet, sorghum, etc.
The main functions of magnesium in the human body are: to participate in the synthesis of RNA and DNA; to participate in the conduction of neuromuscular; to constitute the main component of a variety of enzymes in the human body; to activate some enzymes in the body (such as peptidase and phospholipase); to maintain the smoothness of the skin. If the human body is short of magnesium, it may have facial and limb muscle tremor and mental tension, emotional instability and affect the overall beauty. Magnesium is widely found in all kinds of food, generally not lacking. The food with the richest magnesium content includes soybeans, mushrooms, sweet potatoes, bananas, black dates, red peppers, laver, hard fruits, etc.
