Soda can't drink the beauty and health you want
In the past two years, soda has quietly become popular. Compared with other beverages, soda has low calories and various flavors, making it a favorite drink for many people. As the weather turned hot, the sales of this drink soared. At the same time, some rumors about the "special effects" of soda, such as antioxidants and nourishing the stomach, also began to brush the circle of friends. However, is soda really so magical?
Can soda water beautify beauty?
The truth: soda is weakly alkaline, and skin care uses weakly acidic products
Heart of beauty in everyone. On the Internet, soda water has been spread to the gods, saying that the trace elements contained in it have anti-oxidation function, which can delay the aging of the skin. Washing the face directly with soda water can soften the skin. Can soda really beautify?
"This statement is inaccurate." Li Heng, director of the Hubei Provincial Hospital of Traditional Chinese Medicine, said in an interview with a reporter from the Science and Technology Daily.
Li Heng explained that you first need to understand what is anti-oxidation. In the continuous contact with the external environment, the human body will generate free radicals in the human body. Antioxidant is the abbreviation of antioxidant free radicals. Most of human aging and diseases are related to the production of excessive free radicals. The mechanism of anti-oxidation is to directly act on free radicals, or indirectly consume substances that easily generate free radicals to prevent further reactions. While the human body produces free radicals, it also produces antioxidants that resist free radicals to counteract the oxidative attack of free radicals on human cells. The antioxidant system of the human body is a relatively complete and complex functional system. The stronger the body's antioxidant capacity, the healthier it is, the slower its aging and the longer its lifespan.
Skin aging refers to the long-term exposure of the skin to ultraviolet rays, dust, various radiations, and the influence of various factors such as diet and stress. An oxidative reaction will occur, generating free radicals. Cells, which in turn cause aging. The signs of skin aging mainly include dull and uneven skin tone, dry skin, fine lines and spots.
Li Heng said that soda water is an aqueous solution of sodium bicarbonate, which is weakly alkaline and can be disinfected and disinfected externally for medical use. At present, there is no scientific basis to confirm that its external use has good antioxidant effect. In fact, human skin is weakly acidic, so choose weakly acidic skin care products. In skin care products, common antioxidants include vitamin C, vitamin E, superoxide dismutase, and coenzyme Q10.
Drink soda often to nourish the stomach?
The truth: excessive stomach acid secretion can be consumed in moderation, healthy people often drink sodium and exceed the standard
In life, I often hear the saying that soda water is alkaline water. Drinking soda water can neutralize stomach acid and achieve the effect of nourishing the stomach. What is the fact?
Song Xin, a dietitian at Beijing Chaoyang Hospital affiliated to Capital Medical University, has done popular science specifically. He introduced that soda water is two categories of natural soda water and synthetic soda water. In addition to sodium bicarbonate, natural soda water also contains many trace elements. Most synthetic soda water is prepared by adding sodium bicarbonate with pure water and adding food additives such as sweeteners.
"Because the soda is weakly alkaline, people with excessive gastric acid secretion can drink it in moderation to neutralize the stomach acid and protect the stomach." Song Xin said, but some people are not suitable for drinking soda, such as gastritis with too little gastric acid secretion patient. Furthermore, soda water contains a certain amount of sodium. Therefore, hypertensive patients and some people with kidney disease should drink soda water with caution. Even healthy people should not drink large amounts of soda water for a long time, otherwise the sodium in the diet will be easily exceeded.
Li Heng also said that soda water is an aqueous solution of sodium bicarbonate, which can be formed naturally or artificially produced with weak base effervescent tablets, soda effervescent tablets, etc. The pH value of the gastric juice of healthy people is acidic. After drinking water, the water is absorbed through the gastrointestinal tract, most of which is absorbed in the intestine and a small amount is absorbed in the stomach. For people with excessive gastric acid secretion and patients with gastric ulcers, soda water is weakly alkaline. Drinking moderate amounts can quickly neutralize the excess gastric acid secreted, but its anti-acid effect is weak and short-lived, and its role is limited. Because the gastrointestinal tract through its own adjustment function, it will quickly adjust the pH value of the weakly alkaline soda water into the body to adapt to the pH value of the body environment.
"0 sugar, 0 fat" soda can lose weight?
Truth: Ca n’t replace drinking water, drink it for a long time or increase the risk of obesity
Weak alkaline, pure natural ... With the popularization of the soda health concept, for female consumers, many businesses have even slogans such as "0 sugar, 0 fat", which is favored by young ladies who like drinks and worry about gaining weight . So, is it feasible to use soda instead of drinking water in normal times? Is soda really effective for weight loss?
In this regard, some experts remind consumers that soda water cannot replace drinking water, it is not suitable for all people, because it is weakly alkaline, high sugar content, long-term drinking will bring different degrees of damage to health. Don't be too superstitious about balancing the pH of the body and exaggerating the role of soda. The human body has its own balance mechanism. Over-acid and alkali are not conducive to health.
In Li Heng's view, the human gastrointestinal tract can adjust the body's acid-base balance by itself, and drinking soda will not change the pH and acidity. In addition to containing sodium bicarbonate, natural soda water also contains a variety of trace elements. It is a good drink, but due to lack of resources, natural soda water on the market is rare. "Most common sodas on the market are added with sugar, sweeteners and spices. When you drink it frequently, you should be alert to the effects of high sugar and high calories on the body and increase the risk of obesity, diabetes, high blood fat, and coronary heart disease." Li Heng emphasized.

Can I remove dandruff by washing my hair with soda?
The truth: it does n’t suppress dandruff, it stimulates sebum secretion
What to do if there is too much dandruff and itching? I believe many people have similar problems. Many people on a beauty platform believe that a good way to get rid of dandruff is using baking soda. This is because the grit texture can remove loose or dead skin and tissue. Can baking soda really dandruff? Will this damage the scalp?
"Dandruff is the keratin cells that come off the scalp, which is caused by the continuous peeling of the cuticle of the epidermis. It is divided into physiological dandruff and pathological dandruff." Li Heng said.
Li Heng said that pathological dandruff is due to the lack of vitamins B6, vitamin B12, zinc and other vitamins and minerals, increased sebum secretion, colonization of fungi and bacteria, and the impact of other diseases. A shampoo containing ketoconazole can inhibit or kill fungi that colonize the scalp. A shampoo containing salicylic acid or fruit acid can dissolve the cuticles and allow dandruff to fall off smoothly. The main component of baking soda is sodium bicarbonate. When it is dissolved in water, it is weakly alkaline. It has a very strong ability to remove oil. Washing hair with baking soda can wash the oil very clean, but it can also stimulate a large amount of scalp secretion The sebum does not inhibit the production of dandruff.
Therefore, experts believe that it is not appropriate to often use baking soda to remove dandruff. Baking soda is an alkaline substance. After cleaning the oil secreted on the scalp, it will stimulate the scalp to a certain extent.
