Eat more foods rich in nucleic acids.

This kind of food, such as fish, shrimp, oysters, mushrooms, tremella, honey and so on. , can eliminate age spots. In recent years, it has been found that food supplemented with nucleic acid can not only delay aging, but also prevent skin wrinkles.

The researchers took 30 women as subjects and asked them to take 800 mg of nucleic acid and appropriate amount of vitamin C every day. After a month's observation, nine people's senile plaques disappeared, five people's wrinkles disappeared, eight people's rough skin became richer, and others' skin also improved.

Eat more foods rich in chondroitin.

Such as pig bone soup, beef bone soup, chicken skin, chicken bone soup, etc. , can enhance the elasticity of the skin. Human skin is divided into epidermis, dermis and subcutaneous tissue, and dermis is the main factor affecting the beauty of skin. Dermal is composed of elastic fibers, and chondroitin sulfate is the most important substance that constitutes elastic fibers. If the human body lacks this chondroitin, the skin will lose its elasticity and wrinkle.

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 collagen.

Such as pigskin, trotters, soft-shelled turtles and so on. According to nutritionists' analysis, every100g of pigskin contains 26.4% protein, which is 2.5 times that of pork, while the fat is only 2.27g, which is half that of pork.

In particular, protein in meat skin is mainly composed of collagen. This collagen has the functions of increasing skin water storage, moistening skin and maintaining water balance inside and outside skin tissue cells. Collagen is the main raw material for the growth of skin cells, which can make human skin plump and tender, reduce or disappear wrinkles and make people look young.

Eat more alkaline food.

The acidity and alkalinity of food are not determined by taste, but that food will eventually become acidic or alkaline after entering the human body. Alkaline foods include most vegetables, fruits, bean products and seafood.

Studies have shown that too much acidic food makes blood acidic, and the contents of lactic acid and uric acid in blood increase accordingly. When these substances come to the skin surface with sweat, it will make the skin lifeless and inelastic, especially the skin on the face will be slack and weak, and it will easily crack under the irradiation of cold wind or sunshine.

Eating more alkaline foods can make the blood weakly alkaline, reduce the contents of lactic acid and urea, and reduce the erosion and damage to the skin.

Vitamin A can keep the skin elastic and shiny.

Vitamins C and E are antioxidants, which can prevent subcutaneous fat oxidation, enhance the vitality of skin epidermis and dermal cells, and avoid premature skin aging. Iron and copper can make blood fill the skin, make the skin get enough nutrition and avoid the early appearance of wrinkles.

Pay attention to the intake of foods rich in vitamins A, C, E and trace elements of iron and copper, which is also conducive to anti-wrinkle.
