Modern scientific research found that the delicate and smooth skin is closely related to the content of hyaluronidase in the dermis, and hyaluronidase is closely related to the secretion of estrogen. Scientists recently discovered that when estrogens are secreted by the ovary, estrogen binds to certain specific receptors in the dermis, which promotes the formation of hyaluronidase. This enzyme can promote the skin's absorption of water, trace elements, vitamins, etc., so that the skin moisture, trace elements and vitamin content is sufficient, so that the skin is delicate and smooth. So how can we make the skin to fit in diet?
(1) Drinking water in moderation. The body tissue fluid has a water content of 72%, and the adult body has a moisture content of 58%-67%. When the body's moisture is reduced, dry skin appears, and the secretion of sebaceous glands decreases, causing the skin to lose its elasticity and even wrinkles. In order to ensure the intake of water, the girl's daily drinking water should be about 1200 ml.
(2) Eat foods rich in vitamins. Vitamins play 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 anti-aging skin. Because vitamin E can destroy the chemical activity of free radicals, thus inhibiting aging. Vitamin E also prevents lipofuscin deposition on the skin. Scientists have found that the production of lipofuscin is related to lipid peroxidation. Foods containing vitamin E are cabbage, sunflower oil, rapeseed oil and so on. Vitamins A and B2 are also indispensable substances for smooth and fine skin. When the body is deficient in vitamin A, the skin becomes dry, rough and scaly; in the absence of vitamin B2, there will be mouth white, lip skin cracking, desquamation and pigmentation. Vitamin A-rich foods include animal liver, cod liver oil, milk, butter, eggs, and orange-red vegetables and fruits. Foods rich in vitamin B2 include liver, kidney, heart, eggs, and milk.
(3) eat more foods containing iron. The skin is shiny and ruddy and needs to supply enough blood. Iron is one of the main components of hemoglobin in the blood. Therefore, iron-rich foods should be eaten. Such as animal liver, egg yolk, kelp, seaweed and so on.
(4) Increase the intake of collagen- and elastin-rich foods. Collagen can make cells full, so that the skin filling, wrinkles reduce; elastin can make people's skin elasticity, so that the skin is smooth and elastic. The foods rich in collagen and elastin are trotters, animal tendons and pig skins.
(5) Pay attention to the intake of alkaline foods. The fish, meat, poultry, eggs, grains and grains eaten in daily life are all physiologically acidic. Weight-acidic foods increase the levels of lactic acid and uric acid in body fluids and blood. When organic acids cannot be excreted in time, sensitive epidermal cells are eroded and the skin loses its delicateness and elasticity. In order to neutralize acidic constituents in the body, you should eat physiological alkaline foods such as apples, pears, oranges, and vegetables.
In addition, the skin should avoid external stimuli, the summer sun, and the cold wind in winter, will make the skin rough, so according to seasonal changes, timely protective measures. Do not wash your skin too often. Repeatedly rubbing will not allow the damaged skin cells to regenerate. Pay attention to skin protection, avoid contact with excessively acidic and over-alkaline substances, choose appropriate cosmetics and cleaning products according to your skin, and massage appropriately.
