Modern scientific research has found that the smoothness of skin is closely related to the content of hyaluronidase in dermis, and hyaluronidase is closely related to the secretion of estrogen. Recently, scientists have found that when the estrogen secreted by the ovary increases, estrogen will combine with some specific receptors in the dermis, thus promoting the formation of hyaluronidase. This enzyme can promote the skin to absorb water, trace elements and vitamins, so as to make the skin full of water, trace elements and vitamins, and make the skin delicate and smooth. So how can we adapt our skin to diet?
(1) The water content of human tissue fluid is 72% when drinking water properly, and it is 58% ~ 67% for adults. When the body moisture decreases, the skin will be dry, the secretion of sebaceous glands will decrease, which will make the skin lose elasticity and even wrinkle. In order to ensure water intake, girls should drink about 1200ml every day.
(2) Eating foods rich in vitamins often plays an important role in preventing skin aging and keeping skin delicate and moist. Japanese scholars have found that vitamin E plays an important role in skin anti-aging. Because vitamin e can destroy the chemical activity of free radicals, thus inhibiting aging. Vitamin E can also prevent lipofuscin from depositing on the skin. Scientists have found that the formation of lipofuscin is related to lipid peroxide. Foods rich in vitamin E include cabbage, sunflower oil and rapeseed oil. Vitamins A and B2 are also indispensable substances for smooth and moist skin. When the human body lacks vitamin A, the skin will become dry, rough and scaly; If vitamin B2 is lacking, there will be oral milk, chapped skin, desquamation and pigmentation. Foods rich in vitamin A include animal liver, cod liver oil, milk, cream, eggs and orange-red vegetables and fruits. Foods rich in vitamin B2 include liver, kidney, heart, eggs and milk.
(3) Eat more iron-containing foods, your skin is ruddy, and you need adequate blood supply. Iron is one of the main components of heme in blood, so eat more foods rich in iron. Such as animal liver, egg yolk, kelp, laver, etc.
(4) Increase the intake of foods rich in collagen and elastin. Collagen can make cells plump, thus making skin plump and reducing wrinkles; Elastin can enhance the elasticity of human skin, thus making the skin smooth and elastic. Foods rich in collagen and elastin include pig's trotters, animal tendons and pigskin.
(5) Pay attention to the intake of alkaline food. Fish, meat, poultry, eggs and grain eaten in daily life are all physiologically acidic. Too much acidic food will increase the content of lactic acid and uric acid in body fluids and blood. When organic acids cannot be excreted in time, they will erode sensitive epidermal cells and make the skin lose its tenderness and elasticity. In order to neutralize the acidic components in the body, we should eat some physiologically alkaline foods, such as apples, pears, oranges and vegetables.
Vitamins contribute to skin health.
Whitening, anti-aging and anti-wrinkle are the biggest secrets of women's skin. There are various anti-aging and anti-wrinkle cosmetics on the market (such as acid, salicylic acid, A acid, fish protein, grape seed, etc. ), but vitamins still occupy a very important position in modern people's skin care. Among them, vitamins A, C and E have the best skin care effect.
First, the content of vitamin A is quite rich in yellow-green vegetables and fruits, viscera, liver, egg yolk, margarine, milk and cod liver oil. However, vitamin A must be transformed in the human body before it can play a role. For the skin, it can regulate the metabolism of epidermis and stratum corneum, protect epidermis and mucosa, and make bacteria not easy to invade. Therefore, vitamin A is widely used in clinic, such as anti-aging, wrinkle removal, skin spot fading, smoothness and tenderness, and skin cancer prevention. If you take too much vitamin A, you will have headache, nausea, vomiting and bone lesions. Especially pregnant women, we should pay special attention to its safe dose to avoid giving birth to deformed children.
Second, vitamin E Vitamin E is rich in cereals, wheat germ oil, cottonseed oil, green leafy vegetables, egg yolks, nuts, meat and dairy products. Vitamin E can reduce the oxidation of vitamin A and polyunsaturated fatty acids, control cell oxidation, promote wound healing, and inhibit skin sunburn and cancer.
Production. Generally speaking, if vitamin E and vitamin C can be used together, they can complement each other and enhance their functions. Vitamin e is fat-soluble. If taken in excess of the safe dose for a long time, it will lead to phlebitis, pulmonary embolism, hyperlipidemia and other side effects, so it should be used with caution.
Third, the whitening effect of vitamin C is mainly anti-inflammatory, which can prevent sunburn, and vitamin C can also promote wound healing. If it is lacking, it will affect the function of connective tissue, making it vulnerable to free radicals and causing degeneration. However, vitamin C is an important antioxidant to repair these injuries. Therefore, it has been widely used in anti-aging and repairing sun damage recently.
The three vitamins have similar functions and complement each other, because they are all good antioxidants, which can eliminate harmful free radicals formed after improper sun exposure.

Modern scientific research has found that Lycium barbarum contains a lot of nutrients such as carotene, vitamin A, B 1, B2, C, nicotinic acid, phosphorus and iron. As a simple beauty and dietotherapy remedy, Lycium barbarum can be soaked in wine, made into Lycium barbarum paste together with longan pulp, crystal sugar and honey, and made into medicated diet together with other foods, such as stewed pig brain with Lycium barbarum, stewed egg with Lycium barbarum, stewed chicken with Lycium barbarum, stewed sheep brain with Lycium barbarum, etc.
Tyrosinase in pale yellow Angelica sinensis can produce melanin, leading to freckles, black spots and senile plaques. The higher its activity, the earlier and more senile plaques appear. Modern scientific experiments have proved that Angelica sinensis aqueous solution has a strong inhibitory effect on tyrosinase activity, so it has anti-aging and beauty effects. Angelica sinensis can be decocted in water as medicinal juice, and made into Angelica wine together with rice and noodles.

Some scholars believe that intestinal obstruction and intestinal Escherichia coli will decompose protein to produce toxic ammonia substances, which will have adverse effects on human body and accelerate the aging of the body after being absorbed into the blood. The intestinal function of white radish can inhibit this unfavorable factor, thus playing the role of nourishing face and benefiting blood.
