With the continuous development of society, everyone has a love of beauty. Not only are more and more women concerned about their skin, but men are also beginning to care more and more about their skin condition.
Some people choose to spend a lot of money on skin care products and skin care products in order to maintain their skin, but the effect is not as good as that of simple and healthy "nourishing outside".
"The way to preserve one's health is not before meals." People's health is inseparable from the nutrition of food, and so is healthy skin. Modern scientific research has proved that nutritional imbalance is one of the important reasons for skin aging.
Modern people live a busy and stressful life. Almost two of the three meals a day are eaten outside. Not to mention high oil and high salt, the possibility of ensuring a balanced intake of nutrients needed every day is simply too small. Coupled with long-term exposure to polluted environment-air pollution, computer radiation, air conditioning environment, etc. , will bring different degrees of damage to the skin.
Diet is an important part of skin beauty. If we can pay attention to supplement various nutrients beneficial to the skin in our daily life, we can make the injured skin glow again. Therefore, in order to maintain and restore the beauty of the skin, diet is one of the best choices. Today, let's take a look at six favorite nutrients of skin.
Six favorite nutrients of skin
1. Collagen makes skin smooth and full.
Young skin looks smooth, full, soft and elastic. One of the reasons is that there are two substances in human dermis: collagen and elastic fiber. Collagen has a good supporting role in the skin, which can make the skin look very rich.
In addition, it also has a strong ability to absorb water in the surrounding environment. When it is covered on the skin, it can prevent water from disappearing from the surface, and the moisturizing effect is very obvious.
However, with the increase of people's age, the loss rate of collagen in human body begins to accelerate; Coupled with ultraviolet radiation and in vivo oxidation, it may destroy the structure of collagen and make it lose its original elasticity, which is the reason for wrinkles and facial skin relaxation.
In life, there are many foods rich in collagen, such as pig's trotters, pigskin, chicken skin, fish skin, tremella, soybeans and seafood.
2. vitamin c: make the skin white and bright.
The effect of vitamin C on skin is mainly reflected in three aspects: whitening, wrinkle removal and anti-aging. On the one hand, it can inhibit the activity of tyrosinase in the skin and effectively reduce the production of melanin, thus making the skin white and tender and the dark spots fade; It can also participate in the formation of collagen and enhance the skin's tolerance to ultraviolet rays.
Therefore, vitamin C plays an important role in improving skin color, increasing skin luster and preventing skin dryness. It is also helpful to promote metabolism and delay aging.
Vitamin C is widely found in fresh fruits and vegetables, such as tomatoes, cauliflowers, sweet peppers, dark leafy vegetables, bitter gourd, citrus, grapefruit, apples, grapes, kiwis and fresh dates.
3. Vitamin A: the body's natural moisturizer
Vitamin A is the basic substance to maintain the normal function of skin tissue, which can regulate the process of skin keratinization, especially to maintain the secretion function of sebaceous glands and sweat glands.
If vitamin A is deficient, it will easily lead to dull facial skin and cause skin problems such as acne. Derivatives of vitamin A play an important role in dermatological drugs and are widely used in wrinkle removal, anti-aging and freckle removal.
Vitamin A exists only in animals, not in plants. But many vegetables and fruits contain provitamin A-carotene, which can be decomposed into vitamin A in human body.
Among the food sources of vitamin A, animal liver is the highest, such as pig liver, chicken liver and sheep liver. Egg yolk, milk, crab and fish are rich in vitamin A. ..
Plant food mainly includes yellow food, green vegetables and some fruits, such as carrots, tomatoes, green peppers, spinach, sweet potatoes, pumpkins and mangoes. Because vitamin A is a fat-soluble vitamin, it is beneficial to its absorption and utilization to ingest proper amount of oil.
4. vitamin e: delaying aging
Vitamin E is a fat-soluble vitamin with antioxidant effect. In addition, vitamin E can "moisten" collagen fibers and elastic fibers in the skin, and can also treat skin problems such as senile plaque and chloasma.
When vitamin E is deficient, the free radicals produced during human metabolism can not only cause lipid peroxidation of biofilm, but also destroy the structure and function of cell membrane and form lipofuscin. But also denature protein, inactivate enzymes and hormone, cause metabolic disorder and promote body aging.
Foods rich in vitamin E include: squeezed vegetable oil, fruits and vegetables, nuts, lean meat, dairy products, eggs, citrus peel and so on.
Fruits and vegetables include: kiwi fruit, spinach, Chinese cabbage, cabbage, lettuce, sweet potato and yam. Nuts include almonds, hazelnuts and walnuts.
The pressed vegetable oil includes sunflower seed, sesame seed, corn, olive, peanut and camellia. In addition, safflower, soybean, cottonseed, wheat germ and cod liver oil all contain a certain amount of vitamin E.
5. Eat more foods containing iron and zinc.
Iron is an essential trace element for human body. If you want to make your skin shiny and ruddy, you need to supply enough blood, and iron is one of the important components of heme in blood, so you should eat more foods rich in iron.
Animal foods contain more iron in aquatic products such as liver, lean meat, egg yolk and fish, while plant foods contain more iron in beans, nuts, leafy vegetables and fruits such as hawthorn and strawberries. The "meat factor" in fish, meat and poultry food is beneficial to the absorption of iron, which means that the iron supplement effect of meat food is better than that of plant food.
As one of the essential trace elements for human body, zinc has the functions of promoting growth and development, promoting vitamin A metabolism and enhancing skin resistance. Zinc can help tighten the skin, maintain the elasticity and toughness of the skin, reduce wrinkles, promote wound healing, stimulate the growth of new cells, and prevent and treat acne. It also has a positive effect on delaying facial appearance and skin aging.
There are many foods containing zinc, such as milk, fish, meat and brown rice. The zinc content of legumes in plant foods is high, and in addition, the zinc content of fungi foods is particularly rich.
6. Lecithin: naturally detoxify and lubricate the skin.
Lecithin, known as the "third nutrient" alongside protein and vitamins, is an indispensable substance in every cell of human body. If it is lacking, it will reduce the regeneration ability of skin cells and lead to rough and wrinkled skin. It is also a natural antidote that can decompose toxins in the body.
If lecithin can be properly ingested, skin rejuvenation can be guaranteed. Coupled with the good hydrophilicity and lipophilicity of lecithin, the skin will of course be shiny.
Egg yolk is rich in lecithin, and milk, animal liver and soybeans all contain lecithin.
"Good at accepting, indifferent, sweet and sincere, with soft and delicate skin and well-proportioned bones." Diet is closely related to the skin. The beauty of skin is natural from the inside out.
Of course, it is more important to eat less foods that harm the skin than to eat more of them. For example: be sure to eat less sugar and less processed food; Drink less if you are allergic to dairy products; Eat less herbal oil; Prevent long-term exposure; There are also girls who don't smoke, stay up late and overeat.
I wish everyone a beautiful life through a reasonable diet and good skin.
