A reasonable diet is the best way for the skin to absorb nutrients


The skin is the body's largest barrier organ and can only absorb limited nutrients. The epidermis can absorb a part of water and heavy metals, and some fat-soluble substances are also absorbed from the sweat gland ducts, but other macromolecules and collagen are hardly absorbed.
Therefore, the role of skin care products is very limited to solve the problems of aging, wrinkles and sagging of the dermis and subcutaneous tissue. However, I heard that all nutrients, proteins, minerals, vitamins, hyaluronic acid and various polysaccharides added in skin care products can be taken from food and transported into the blood through capillaries to replenish skin cells.
The body is a huge and complex chemical factory, and a single addition of a particular nutrient has little effect. Whether drinking more milk for whitening or eating oranges for whitening, it is basically a single nutritional supplement. Although it is not ineffective, it is very slow. How much of a single nutrient the body can use depends on the body's environment. Therefore, improving the skin through diet is the most effective way, but pay attention to a balanced diet.
According to the latest scientific research, the following dietary habits can beautify the skin for most people
Eating habits 1. A balanced diet that includes as many food types as possible
A balanced diet means that the various nutrients contained in the diet are complete. Not only is the quantity sufficient, but the ratio of various nutrients also needs to be appropriate to maintain a relative balance with the body's needs. Failure to maintain this balance for a period of time can affect your physical health. For example, some people are very "partial eclipse", eating what they like to eat all the time, and not eating what they don't like at all, which inevitably leads to excess of some nutrients and deficiency of others.
Dietary habits 2. Low salt content
Studies show that eating too much salt can lead to freckles. This is very troublesome for women. One of the dangers of too much salt is the possibility of freckles on the skin. Eating too much animal fat and protein at the same time will affect the normal metabolism of the liver, making the skin freckles obvious. Freckles tend to fall in love with "salty people". Women who care about skin need to be careful.
Women with heavy tastes on weekdays like dishes with a lot of salt, whether they are cooking alone or ordering outside, and their skin is more prone to wrinkles in the long run. If you want to have good skin, the more scientific method is to drink more water to help the skin detoxify, and the daily salt intake should not exceed 6 grams.
Dietary habits 3. Low sugar and low carbohydrate
Most women can't resist the temptation of various cakes and sweets, but sugar can affect the skin. Sugars react with proteins to form glycation end products. With age, the collagen in the skin will slowly saccharify, thereby reducing the elasticity of the skin, which can seriously lead to hardening of the skin. In addition, advanced glycation end products inhibit the production of new collagen, accelerate the rate of skin sagging and sagging, induce cellular inflammation, and lead to skin cell death.
However, that doesn't mean you can't eat sugar at all. Sugar is an important source of energy, and carbohydrates need to account for the majority of our daily diet 55%. Sugars are carbohydrates such as dietary fiber, starch and sugar. It's best to choose foods that are low on the glycemic index, don't significantly increase blood sugar levels, and are slow to digest to give some satiety, such as whole grains like grains and beans, potatoes, and brown rice. The daily intake of sucrose should not exceed 50 grams.
Dietary habits 4. Reasonable supplementation of high-quality protein
The skin is the largest organ of the human body, and skin cells are constantly renewed and synthesized. It is usually possible to eat more foods with high-quality protein, which provide enough ingredients for the skin to produce collagen. Recommended fish and chicken, variety of beans and eggs.
Dietary habits 5. Sufficient supply of trace elements and vitamins
The proportion of trace elements and vitamins in the body is low, but they are definitely essential for the body. Women need to eat more iron-rich foods such as animal blood, lean meat, and liver to keep their skin rosy. At the same time, it should be matched with vegetables and fruits containing vitamin C, which can promote the body's absorption of iron.
B vitamins are closely related to skin health. Once they are deficient, it will inevitably lead to rough skin, melanin precipitation, itching, and seriously affect the appearance of the skin. B vitamins can be obtained from grains, eggs, milk, vegetables and meat products.
Vitamin C promotes collagen synthesis and wound healing, and also has skin lightening effects. Vitamin C can be obtained from citrus fruits, tomatoes and kiwi. If you want to improve your skin, you need to pay attention to nutritional balance and reduce or completely avoid processed foods. At least 30 minutes of aerobic exercise every day can promote blood circulation throughout the body, provide sufficient blood and nutrients for the skin, and delay skin aging.
