1. Eat more foods rich in chondroitin
Such as pork bone soup, beef bone soup, chicken skin, chicken bone soup, etc., can enhance the elasticity of the skin. Human skin is divided into three layers: epidermis, dermis, and subcutaneous tissue. The dermis is the main factor affecting skin beauty. The dermis is composed of elastic fibers, and the most important substance that constitutes elastic fibers is chondroitin sulfate. If the human 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.
2. Eat more nucleic acid-rich foods
Such foods, such as fish, shrimp, oysters, mushrooms, white fungus, honey, etc., can eliminate age spots. Studies have found that supplementing nucleic acid foods can not only delay aging, but also prevent the production of skin wrinkles.
3. Eat more alkaline-rich foods
Acidic and alkaline foods are not determined by taste, but refer to the final acidity or alkalinity of food after entering the human body. Alkaline foods include most vegetables, fruits, soy products and seafood. Studies have shown that excessive acidic foods make the blood acidic, so that the lactic acid and uric acid content in the blood increase accordingly. When these substances come to the surface of the skin with sweat, the skin will become inactive and lose its elasticity, especially the facial skin will be loose and weak, and it will be easy to crack when exposed to cold wind or sunlight. Eating more alkaline foods can make the blood appear weakly alkaline, reduce the content of lactic acid and urea, and reduce the erosion and damage to the skin.
4. Eat more collagen-rich foods
For example, pig skin, pig trotters, soft-shelled turtle, etc. According to the analysis of nutritionists, 100 grams of pork skin contains 26.4% protein, which is 2.5 times that of pork, while the fat is only 2.27 grams, which is half of pork. Especially the protein in the meat skin, the main component is collagen. This collagen has the function of increasing the water storage of the skin, moisturizing the skin, and maintaining the balance of moisture inside and outside the cells of the skin tissue. Collagen is the main raw material for the growth of skin cells, which can make human skin grow plump, white and tender, reduce or disappear wrinkles, and make people look younger.
