Such as pork bone soup, beef bone soup, chicken skin, chicken bone soup, etc., can enhance skin elasticity. Human skin is divided into three layers: epidermis, dermis, and subcutaneous tissue. The dermis is the main part that affects skin beauty. The dermis is composed of elastic fibers, and the main substance that makes up elastic fibers is chondroitin sulfate. If the body lacks this chondroitin, the skin loses its elasticity and wrinkles appear. Therefore, eating more foods rich in chondroitin sulfate can delay the occurrence of skin wrinkles and keep the skin elastic and delicate. Eat more foods rich in nucleic acids
These foods, such as fish, shrimp, oysters, mushrooms, tremella, honey, etc., can eliminate age spots. In recent years, research has found that supplementing with nucleic acid foods can not only delay aging but also prevent the formation of skin wrinkles. Researchers used 30 women as subjects, having them take 800 mg of nucleic acid and an appropriate amount of vitamin C daily. After one month of observation, 9 people's age spots disappeared, 5 people's wrinkles disappeared, 8 people's rough skin became more supple, and everyone else's skin improved compared to before. Eat more alkaline foods
Acidic and alkaline foods are not determined by their taste, but by whether they become acidic or alkaline in the human body. Alkaline foods include most vegetables, fruits, bean products, and seafood. Studies have shown that excessive acidic foods make the blood acidic, increasing the content of lactic acid and uric acid in the blood. These substances come to the surface of the skin with sweat, making the skin dull and lose its elasticity, especially making facial skin slack and weak, which can easily crack when exposed to cold wind or strong sunlight. Eating more alkaline foods can make the blood slightly alkaline, reduce the content of lactic acid and urea, and reduce the erosion and damage to the skin. Eat more foods rich in collagen
For example, pig skin, pig's trotters, soft-shelled turtle, etc. According to nutritionists' analysis, every 100 grams of pig skin contains 26.4% protein, which is 2.5 times that of pork, while the fat is only 2.27 grams, half of that of pork. Especially the protein in the skin is mainly composed of collagen. This collagen can increase the skin's water storage function, moisturize the skin, and maintain the balance of water inside and outside skin cells. Collagen is the main raw material for skin cell growth, which can make the human skin fuller, fairer and younger, reduce or eliminate wrinkles, and make people look younger. Vitamin A can maintain the suppleness and gloss of the skin
Vitamins C and E are antioxidants that can prevent the oxidation of subcutaneous fat, enhance the vitality of epidermal and dermal cells, and avoid premature aging of the skin. Iron and copper can make the blood fill the skin, provide the skin with sufficient nutrition, and avoid the early appearance of wrinkles. Paying attention to the intake of foods rich in vitamins A, C, E and trace elements iron and copper is also beneficial to anti-wrinkle.
