What nutrition does skin formation need? Skin is the largest organ of the human body and belongs to a part of the human body. The maintenance of skin needs the nourishment of various nutrients, which can be absorbed from the diet. So what nutrition does skin generation need?
What nutrition does skin formation need? 1 1. What nutrition does the skin need?
(1) protein.
Protein is an indispensable substance in body tissues, the main component of cells and the origin of life. It constitutes various nucleic acids, antibodies and some hormones; Can promote the growth and development of the body, supply energy to supplement the consumption of metabolism, and maintain the normal osmotic pressure of capillaries. Without protein, it will affect the growth and development, and the skin will be pale, dry, aging and dull, and there may be malnutrition edema.
⑵ Lipids.
Lipids are composed of fats, lipids and their derivatives. Fat can supply the body with heat energy and essential fatty acids, help the absorption of fat-soluble vitamins and make the skin elastic. When lacking, it is easy to suffer from fat-soluble vitamin deficiency and the skin loses elasticity.
(3) sugar.
Starch and sugar are both sugars, also called carbohydrates. The sugar content of normal skin is 50%-70%. Its function is to provide enough energy for the human body. Carbohydrates provide heat energy for the body, help fat burn in the body, and help protein, which constitutes the body itself, synthesize in the body. When it is lacking, it will grow slowly, get tired easily and look dull.
(4) vitamins.
(1) Vitamin A has the function of protecting skin and mucous membrane, and is helpful for the development of bones and teeth. 127 is an essential substance to maintain night vision. If vitamin A is deficient, keratin in hair follicles will be embolized. 127 makes the skin surface dry, rough and even wrinkled.
② Vitamin B participates in glucose metabolism and is a coenzyme of pyruvate oxidative decarboxylase, which can inhibit cholinesterase and maintain normal digestive function. Vitamin B deficiency 1 can cause beriberi, loss of appetite and indigestion.
(3) Vitamin B forms a coenzyme, which promotes intracellular biological oxidation and participates in the metabolism of sugar, protein and fat. Vitamin B deficiency can cause cheilitis, glossitis, oral ulcer, facial acne and other diseases.
④ Vitamin B is closely related to amino acid metabolism, which can promote the absorption of amino acids necessary for cell growth and the production of protein, and affect the synthesis of aminobutyric acid and 5- hydroxytryptamine in tissues. & kloc-0/27 vitamin b deficiency can cause peripheral neuritis and dermatitis.
⑤ Vitamin B 12 is necessary for the formation of red blood cells and healthy tissues. Vitamin B deficiency 12 can cause pernicious anemia and hand and foot pigmentation.
⑥ Vitamin C is an essential component of intercellular substance, which plays a role in hydrogen transfer, detoxification and&; 127 catalysis. Vitamin C deficiency can lead to dry and rough skin, subcutaneous bleeding, gingival bleeding and acne.
⑦ Vitamin D can regulate calcium and phosphorus metabolism, promote calcium absorption, and has a negative effect on calcium and phosphorus precipitation in bone tissue. 127 can directly promote osteogenesis. Vitamin D deficiency can lead to rickets.
⑧ Vitamin E has the functions of antioxidation, promoting metabolism and improving skin blood circulation. 127 can maintain normal capillary permeability and prevent skin aging. Vitamin e deficiency can lead to rough skin and aging.
5] zinc. Zinc participates in the synthesis of various enzymes in the body, maintains the elasticity, toughness and density of skin mucosa, and makes it tender and smooth. When zinc is deficient, skin overflow increases, and the face is prone to acne, which makes the skin purulent.
[6] iron. Iron is the basic component of hemoglobin. Transporting oxygen and carbon dioxide in blood is an important part of blood. Iron deficiency can cause anemia, pale skin, dry skin, chapped mouth and other symptoms.
(7) water. Water is an important part of human body, accounting for 75% of human body weight. & kloc-0/27 and the moisture in skin accounts for 18%-20% of the moisture in human body. Most water is stored in the dermis, and women's skin stores more water than men's. Water exists in human body in three forms: one is water in cells (called cell sap); The second is tissue fluid, which mainly exists between cells; The third is in the blood. Water plays a role as a solvent in the human body, transporting nutrients, excreting waste and regulating body temperature, which is an essential substance for the human body.
It's inorganic salt. Inorganic salts are a certain amount of minerals contained in the human body. Such as sodium chloride, potassium chloride, sodium bicarbonate, etc. Sodium and potassium participate in human nerve and muscle activities, and too much or too little blood will cause muscle relaxation.
What nutrition does skin formation need? So how to maintain the skin?
1, keep your skin clean.
The skin can breathe. If the face is not clean, it is most likely to cause pore blockage and acne, which will affect the beauty of the whole face. It is best to use facial cleanser when washing your face. Choose a facial cleanser that is gentle and does not harm the skin. Don't choose facial cleanser that is irritating or too clean. People who like makeup should clean their faces with makeup remover before going to bed, and then use water emulsion reasonably to keep their skin moist.
2. Eat more fruits and vegetables every day.
As we all know, eating more fruits and vegetables is good for all aspects of the body, especially for the skin. Vegetables and fruits are rich in nutrients and vitamins, and also have collagen needed by the skin. Eating more fruits and vegetables every day can make your skin smoother and look more delicate. More is to regulate the skin from the internal diet, so that the skin contains sufficient nutrition.
3. Do a good job of moisturizing the skin.
When the weather is too cold or too hot in summer, the skin is easy to dry and lose moisture. At this time, it is necessary to do a good job of moisturizing the skin at ordinary times. Just use simple water emulsion when you wake up in the morning and before going to bed at night. Simply moisturize after washing your face. After the basic moisturizing work is done, the skin will become watertight and there will be no obvious dryness and roughness.
4. Sun protection should be done well
Many people have a misconception that you don't need to wear sunscreen if you don't go out and stay indoors. No, you will also be exposed to sunlight, that is, ultraviolet rays. Do a good job of sun protection, will not let the skin age, and stay young for a long time. No matter what weather or season, we should do a good job in sun protection, both physical sun protection and sunscreen can be used.
What nutrition does skin formation need? 3 0 1, water.
Water is an important part of human body, accounting for about 70% of human body weight. Among them, the skin contains about 20% of the human body's water, which is mainly stored in the dermis. Women's skin stores more water than men's, so it looks more delicate and smooth. If the skin is short of water, problems such as dryness, long spots and long wrinkles will appear one after another.
0 2, protein
Protein is the main component of cells and an indispensable part of skin. Collagen, which is a kind of protein that we often say. Without protein, the skin will become pale, dry, aging and dull.
0 3, fat
Many people don't like being fat and think that being fat means being fat. In fact, in addition to providing energy to the human body, fat can also help the absorption of fat-soluble vitamins and make the skin elastic. Insufficient fat can also cause skin to lose elasticity.
0 4, carbohydrate
Carbohydrate is what we often say, and it can also provide energy for human body. The sugar content of healthy skin is about 60%, which can help the synthesis of protein. Carbohydrates in the skin are mainly glycogen, glucose and mucopolysaccharide. The sucrose we usually eat is not only harmful to the skin, but also leads to obesity and acne. Lack of sugar will make the skin dull and dull.
0 5, vitamin
Vitamins are of great significance for maintaining human growth and physiological functions, and the human body cannot synthesize them by itself, so it can only be supplemented from the outside. Once a certain vitamin is deficient, the body will inevitably have some corresponding clinical manifestations.
Lack of vitamin A can lead to dry and rough skin; Lack of vitamin B can cause skin inflammation; Lack of vitamin c can lead to red petechiae on the skin; Lack of vitamin E can lead to rough skin, aging and other problems.
0 6, minerals
Also known as inorganic salts, including calcium, iron, zinc, phosphorus, potassium, sodium and other elements, each element has its special physiological function and is an indispensable nutrient element for the skin.
