Moisturizing, delicate, soft and elastic skin is everyone’s dream skin. However, some people’s skin is unsatisfactory, appearing rough and lacking luster. The reasons are analyzed, on the one hand, it is related to the influence of genetic factors and diseases, and on the other hand, it is related to the acquired nutrition and maintenance.

Modern scientific research has found that the fineness and smoothness of the skin is closely related to the content of hyaluronidase in the dermis. Hyaluronidase is closely related to the secretion of male hormones. Scientists have recently discovered that when estrogen secretion from the ovary increases, estrogen binds to certain specific receptors in the dermis, thereby promoting the formation of glutenase. This enzyme can promote the skin’s absorption of moisture, trace elements, vitamins and other nutrients, making the skin moist, smooth and delicate.

(1) Moisture:

The water content of human tissue fluid is 72%, and the water content of adults is 58% to 67%. When the body’s water is reduced, the skin will be dry and the secretion of sebaceous glands will be reduced, so that the skin loses elasticity and even wrinkles. Therefore, in order to ensure the intake of water, the daily water intake of normal people should be no less than 1000 ml.

(2) Potassium-containing foods:

Potassium is essential for maintaining the pH of the skin and the body, maintaining intracellular osmotic pressure and normal metabolism. The normal adult potassium requirement is 2 to 4 grams per day. Main food sources: bran, peas, soybeans, potatoes, sweet potatoes, radishes, mustard, peanuts, kelp, seaweed, meat floss, coffee, tea, etc.

(3) Foods containing vitamin A:

Vitamin A can make eyes bright, skin moisturizing and delicate. Main food sources: animal liver (dog liver should not be eaten too much), whole milk and its products, green and yellow vegetables, sweet potatoes, carrots, green peppers, pumpkins, etc.

(4) Foods containing vitamin B1:

Lack of vitamin B1 can cause mucous membrane allergy and skin inflammation. Main food sources: animal offal, meat, beans and peanuts, brown rice. Drinking a lot of tea or eating too much carp, herring (herring), shrimp, etc. will affect the absorption of vitamin B1.

(5) Foods containing vitamin B2:

Vitamin B2 is also called riboflavin. Its function is to maintain normal skin metabolism, make skin smooth and smooth, flatten wrinkles, reduce pigmentation, and eliminate spots. Main food sources: animal liver, kidney, lean meat, milk, eggs, soybeans and their products, green vegetables.

(6) Foods containing vitamin C:

Vitamin C is an antioxidant that reduces skin pigmentation and prevents melanin production, thus restoring tanned skin to its white and smooth appearance. Excessive intake of vitamin C preparations can lead to stones or ulcers. Main food sources: mandarin, tangerine, orange, pomelo, fresh jujube, kiwi, strawberry, plow, cauliflower, lettuce leaves, lemon, tomato, hawthorn and various dark vegetables.

(7) Foods containing vitamin D:

Vitamin D can prevent mild rickets in children and osteoporosis in middle-aged and elderly people. Main food sources: sea fish, animal liver and egg yolk, cream, cheese, cod liver oil, etc.

(8) Foods containing vitamin E:

Vitamin E can improve the absorption rate of vitamin A, reduce and prevent the production and deposition of lipofuscin in the skin, can prevent facial acne in teenagers, and has the effect of skin care and beauty, anti-aging and longevity. Main food sources: vegetable oil, soybean and its products, mung bean, adzuki bean, black sesame, walnut, duck egg, garlic, spinach, crucian carp and shrimp.

(9) Fiber-containing foods:

Constipation can cause the body to produce various symptoms and induce various diseases. Constipation can also make the complexion chlorosis and lose its due luster. Fiber-rich foods can prevent constipation. Mainly: various vegetables, fruits and non-refined foods.

(10) Foods rich in iron and zinc:

The glow of the skin is ruddy and needs plenty of blood. Iron is the main component of hemoglobin in the blood. Zinc is also an indispensable trace element in the body, which participates in various physiological activities of the human body. Zinc has the highest content in the skin, accounting for more than 20%, which determines the smoothness and elasticity of the skin. There is a saying that “the skin is zinc-plated”. Therefore, should eat more foods rich in iron and zinc, such as animal liver, egg yolk, kelp, sesame paste, lean meat, oysters and seafood, to promote skin fitness.

(11) Alkaline food:

Rough skin is often caused by high blood acidity. The fish, meat, poultry, eggs, and grains eaten in the daily diet are all physiologically acidic.

Physiologically acidic foods will increase the content of lactic acid and uric acid in the body and blood. When the organic acid cannot be excreted in time, it will erode the sensitive epidermal cells and make the skin lose its delicateness and elasticity. However, the alkaline inorganic salts in fresh vegetables and fruits, such as calcium, sodium, magnesium, potassium, etc., are relatively high in content. Regularly eating fresh vegetables can make the body sufficient in alkaline substances. The acidic substances in the body are quickly neutralized into non-toxic compounds and excreted, so that the blood is maintained in a relatively ideal weak alkaline state, and the skin is kept smooth and moisturizing. Therefore, it is advocated that meat and vegetarian food should be reasonably matched, and the proportion of meat and vegetarian food should be adjusted according to different ages.

In general, the diet after adulthood should be partial, and as much as possible can be obtained from plant protein, such as cystine and tryptophan, which can prevent rough skin, so as to maintain the skin’s water content at about 10%, delay skin aging, and change the skin. rough condition. Eat more physiological alkaline foods to make the skin smooth and beautiful.
