The most common ones are pigskin, trotters and soft-shelled turtles. Statistics show that every 100 grams of pigskin contains 26.4% protein, which is 2.5 times that of pork, but the fat is only half of that of pork-2.27 grams. It is worth noting that the main component of protein in this kind of skin is collagen.
This kind of collagen can help the skin retain moisture, moisturize the skin and maintain the balance of moisture inside and outside the skin tissue cells. Collagen is an essential raw material for the growth of skin cells, which can make skin white, tender and smooth, effectively reduce wrinkles and make people look younger. In addition, vitamin A can maintain the flexibility and luster of the skin. Vitamins C and E are good antioxidants, which can prevent the oxidation of fat under the skin, make the epidermis and dermal cells of the skin full of vitality and delay the aging of the skin.
Iron and copper can promote blood circulation under the skin, so that the skin can get enough nutrition and prevent wrinkles. Therefore, eating more foods rich in vitamins A, C, E and trace elements such as iron and copper in daily diet can also help to resist wrinkles.
2. Foods rich in chondroitin
You can eat more pig bone soup, beef bone soup, chicken skin and chicken bone soup to make your skin more elastic. There are three layers of human skin: epidermis, dermis and subcutaneous tissue, among which dermis is the most relevant to skin beauty. Dermal is composed of elastic fibers, and the main component of elastic fibers is chondroitin sulfate. Once the human body lacks this chondroitin, the skin has no elasticity and is more prone to wrinkles. Therefore, eating more foods containing chondroitin can also help anti-wrinkle.
As long as you pay more attention to supplement some beauty foods in your daily diet, the effect may be that many high-priced skin care products can't be bought, so women should pay attention to the fact that beauty is eaten!
3. Fruits rich in vitamin C.
Cherry: It has been a beauty fruit since ancient times. Cherry juice is the favorite of many whitening products, which can help facial skin to be white and ruddy, remove wrinkles and remove spots. Cherry is not only rich in vitamin C, but also extremely rich in iron, which is 13 times that of hawthorn and 20 times that of apple. In addition to high iron content, it also contains vitamin A, which can balance cortical secretion and delay aging, and help activate cells and beautify skin.
Pomegranate: Delicate red pomegranate has been proved to have strong antioxidant effect. It contains an ingredient called ellagic acid, which can protect cells from environmental pollution and UV rays, nourish cells and slow down the aging of the body. Studies have shown that ellagic acid is more "powerful" in radiation protection than polyphenols contained in red wine and green tea.
Carrots: Carrots are known as "skin food" and can moisturize the skin. Carrots are rich in pectin, which can combine with mercury, so that harmful components in the human body can be discharged, and the skin looks more delicate and ruddy. It contains beta carotene, which can resist oxidation and whiten skin, prevent melanin precipitation, and remove excess keratin from skin. It also contains vitamin e, which is indispensable for oxidation resistance.
Olive: As early as in ancient Greece, the olive tree was a symbol of life and health. Besides being eaten as healthy food, it also had outstanding cosmetic effects. Olive trees can extract skin care essence from leaves to fruits. Olive leaf extract helps skin cells to resist oxidation caused by pollution, ultraviolet rays and pressure; Olive fruit, on the other hand, contains another powerful antioxidant component-phenolic compound, which can provide double antioxidant repair after combining with oleuropein.
