1, balance the body pH value. The acid-base balance in blood is very important to human body, and the blood environment with excessive acid or alkali will cause fatal damage to human organs, tissues and brain. Soaking in water can help regulate the acid-base balance in blood and avoid harm to human tissues due to acid-base imbalance;

2. Effectively relieve constipation. The gas in soaking water will expand with the increase of body temperature, thus stimulating gastrointestinal peristalsis and enhancing gastrointestinal activity, which has a good effect on promoting defecation. Therefore, in Europe and America, people are used to drinking a soda after getting up in the morning to promote gastrointestinal peristalsis;

3. lower cholesterol. According to the four-month human experiment and plasma test in Madrid Hospital in Europe, drinking more bubble water can reduce bad cholesterol (LDL) and increase good cholesterol (HDL). The experimental results show that drinking foam water for a long time can resist the attack of cardiovascular disease (CVD).

4. Activating brain power and promoting blood circulation: In human alveolar tissue, the ability of heme to bind oxygen is inversely proportional to the concentration of carbon dioxide in the body, and carbon dioxide has the physiological function of regulating heme binding and releasing oxygen.

5. Relieve the three highs: soaking in water indirectly improves the metabolic capacity of the human body, makes the physiological function look young, and effectively relieves many symptoms under sub-health.

6, motion sickness, seasickness, airsickness. Motion sickness and seasickness always bring a lot of inconvenience to our life. Drinking ginger juice with bubble water can effectively relieve the symptoms of motion sickness and seasickness and minimize the troubles of such problems.

7. Relieve morning sickness. Pregnant women often vomit, feel tasteless in their mouths, lose appetite, especially in the early pregnancy, and even lead to malnutrition, which is not good for themselves and the fetus. Drinking sugar-free or honey lemon bubble water for pregnant women can relieve the discomfort of morning sickness and keep pregnant women healthy and happy.

8. Food intake control. Drinking soda with meals can increase satiety and avoid obesity caused by overeating.

9. Exhale: Carbonic acid in the blood is very important for the breathing of mammals. When carbon dioxide enters the blood from cells, it will combine with water to form carbonic acid, and then take away an H+ to form bicarbonate ion (HCO3? (Alkaline) bicarbonate ions will enter red blood cells and combine with another H+ to form carbonic acid again. In the lungs, the water in carbonic acid will be taken away and carbon dioxide will be released from the lungs. Controlling the reaction balance between carbonic acid and carbon dioxide is of great significance to control blood acidity.

10, promote skin blood circulation, moisturize skin, effectively resist aging, resist free radicals and produce prevent wrinkles.

Disadvantages of drinking soda

It is estimated that most people think that bubble water is harmful to health, but is this statement really reasonable?

Let's start with the stomach. Carbonated drinks are made by pressurizing water with carbon dioxide, so they will contain a weakly acidic substance-carbonic acid. If you take this drink in large quantities, you will burp or have indigestion. But what if you drink it in moderation? Will it still hurt your digestive system?

The result seems to be just the opposite. In a small-scale double-blind randomized trial, patients with frequent dyspepsia or constipation drank boiled water and soaked water 15 days respectively. Then they received a series of physical examinations. The two conditions of the group who drank soaked water improved, while the group who drank boiled water did not change at all.

If you drink a lot of frothy water, you may feel bloating. Japanese researchers have found that we can make full use of this side effect and make it work for us. They let a group of women fast for one night, and then slowly drink boiled water or soda water. It was found that as long as 250 ml of foaming water was drunk, 900 ml of gas would be released. So it is not surprising that these women's stomachs are slightly swollen. So although they didn't eat, they still felt full. They won't feel sick, and because bubble water will increase your satiety, you can avoid overeating in this way.

Bone problems?

The Framingham Heart Study, which started at 1948, explored more risk factors of heart disease by following a group of patients all the year round. Now, some of their descendants are involved in the study of Framingham osteoporosis. This comprehensive study is conducted every four years and is led by researchers at Tufts University in Boston. In 2006, the team investigated the relationship between bone mineral density and carbonated drinks. * * * 2,500 volunteers participated in this study, and the researchers conducted a detailed study on the types of drinks they drank.

They found that women who drank cola-flavored carbonated drinks three times a week (excluding men) had lower hip bone density. Other carbonated drinks won't have any effect. The researchers put forward a hypothesis that this effect is probably due to the effect of caffeine and phosphoric acid (not contained in sparkling water), but the latter has not been fully understood by human beings. This may hinder the absorption of calcium to some extent-but no one knows the specific mechanism. 10 years later, people still have not reached an agreement on the way diet affects bone health.

It can be seen that drinking bubbly water does not seem to have adverse effects on bones and intestines and stomach. But what about teeth? Do acidic substances (even weak acidic substances) corrode enamel? Maybe not. Although there is little research on soda water, there are many researches on other carbonated drinks. Barry Owens of the College of Stomatology, University of Tennessee, conducted a study in 2007 to compare the effects of different carbonated drinks. According to his research, the original coke is the most acidic, followed by diet coke, and then coffee.

Cumulative effect:

He believes that the key lies not only in the pH value of the beverage itself, but also in how high the acidity of the beverage can be maintained in the presence of saliva and other substances that may affect the acidity-the so-called "buffering capacity". They ranked the buffering capacity of different drinks by evaluation: carbonated drinks without fruit as raw materials, such as cola, are the most acidic (Diet Coke is slightly better), followed by carbonated drinks with fruit as raw materials, juice and coffee. In other words, some carbonated drinks will destroy the hardness of enamel.

Poonam Jain of the School of Dentistry of Southern Illinois University conducted another experiment: he soaked the extracted enamel in different soft drinks for 6 hours, 24 hours and 48 hours respectively, and found that the enamel began to corrode. Some people think that this is quite different from the scene in real life, because it is impossible for us to keep the drink in our mouth for a long time. However, even if each cup lasts only a few seconds, it will still have a significant impact because of years of accumulation.

The picture shows that the corrosion of sweet carbonated drinks will accumulate over time (Source: Getty Images) A case study published in 2009 showed that the front teeth of a 25-year-old bank employee were corroded after drinking carbonated drinks for a long time. He used to drink 0.5 liters of coke every day for four years in a row, and then increased the amount to 1.5 liters every day for three years, plus some juice. This intake is enough to shock everyone. But it depends on the way you drink. According to the study, the man would hold the drink in his mouth for a few seconds at a time, and savor the taste carefully before swallowing it. Swedish researchers compared several ways of drinking beverages, such as short-term sipping, long-term sipping, gulping and sucking, and found that the longer the beverage stays in the mouth, the higher the acidity of the mouth. However, if the beverage is directly sucked to the back of the mouth with a straw, the probability of damage is much lower.

But what about sparkling mineral water? Catriona Brown of Birmingham University soaked human teeth with no signs of corrosion in bubble water with different tastes for 30 minutes to observe the reaction. The surface of these teeth was coated with a layer of varnish, leaving a test area with a diameter of about half a centimeter without varnish. They found that these drinks have the same effect on teeth, sometimes even more obvious than orange juice-scientists already know that orange juice can soften enamel. Lemon, lime and grape-flavored soda are the most sour, probably because they use citric acid to improve the taste.

The research shows that the acidity of sparkling water is only 1% of that of sweet carbonated drinks, so flavored sparkling water will not be as harmless as boiled water. But what about the tasteless bubble water? There is little research on this issue. However, at 200 1, the Birmingham team tested seven different brands of sparkling mineral water, and then poured them on isolated teeth to observe the reaction. They found that the pH value of soft drinks is between 5 and 6 (so the acidity is not as high as 2.5 of some cola drinks), while the pH value of boiled water is 7, which is neutral. In other words, bubble water is indeed weakly acidic as many people guess. However, the corrosive effect of this weakly acidic beverage is only 1% of other carbonated beverages. Of course, the oral environment is different from the jar, but at present, the evidence about the harm of bubble water to human health is not conclusive.

Therefore, for people who don't want to drink boiled water any more, although the bubbling water is weakly acidic, there is no conclusive evidence that it will cause harm to your bones, stomach and teeth. But if you don't want to take risks, try not to let it touch your teeth. Next time someone asks you "boiled water or bubbling water", maybe you should also ask for a straw.

Efficacy and function of bubble water

Sparkling water is a new type of drink with fresh taste, fine foam and various fruit flavors, and it is the most popular healthy drink at present. Soaking in water has many functions, such as suppressing appetite, eliminating constipation, blocking the absorption of sugar and fat, neutralizing acidity in the body and so on, so it is highly sought after by young people.

Bubble water does have the effect of regulating acid-base balance, slimming and refreshing, but it is by no means a panacea for treating various diseases, mainly focusing on health care.

Promote blood circulation:

Carbonated gas can promote blood circulation, and calcium, magnesium and trace elements contained in bubble water can promote blood circulation and help people recover from fatigue.

Hinder the absorption of sugar and fat;

When drinking frothy water during meals, carbonated gas can improve the absorption capacity of dietary fiber and absorb the fat and sugar that would have been absorbed by the intestinal wall, thus preventing the human body from absorbing excess fat and sugar, thus achieving the effect of losing weight.

Eliminate constipation:

Carbonated gas will send a signal to the brain that "food has entered the stomach again" when the stomach expands, and then the brain will feed back to the intestine and send peristalsis instructions to the intestine to make the intestine move more frequently, thus improving constipation.

Control appetite:

Bubble water is generally recommended to be drunk during meals, because after bubble water enters the stomach, it will release carbonic acid gas under the action of body temperature, and food will block the outlet of the stomach. If carbonic acid gas can't go out, it will make the stomach expand and make the stomach feel full in advance, thus controlling appetite.

Neutralizing acidic substances:

Bubble water is formed when carbon dioxide enters the water under high pressure. The formula is H2O+CO2=H2CO3. H2CO3 will be decomposed into H+ and HCO3- after entering human body. HCO 3- is bicarbonate ion, which will undergo hydrolysis reaction to generate H2CO3 and OH- (alkaline), and bicarbonate will also undergo ionization reaction to generate H+ and CO3- (acidic).

Heat dissipation:

When carbonated gas is released from the body, it will take away a lot of heat in the body, so drinking bubble water in summer has a good heatstroke prevention and cooling effect.

Healthy drink method of bubble water

(1) moderate drinking. Drink soda in moderation, and it is best to drink 1.5-2 liters a day, that is, one or two bottles.

Drink with meals. It is best to drink with bubble water, because bubble water can suppress appetite, so drinking it during meals will control the intake of fat and sugar.

Have a drink when you are tired from work. For office workers, 3-4 pm is the most tiring time to go to work. At this time, drinking a glass of soda water can promote blood circulation and restore the spirit.

④ People with gastrointestinal weakness or esophagitis should drink it properly. People with weak stomach or esophagitis should not drink on an empty stomach. Try to drink at meals, preferably at room temperature. The bubbles in the frozen bubble water are very strong and will cause irritation to the stomach.

PH value of bubble water

Bubble water abandons the harm of soda water to the body and retains all kinds of benefits to the body, so it has attracted the attention of many friends who pursue health and quality of life. However, because of the high price of bubble water in the market, it cannot be preserved for a long time. In fact, European and American countries and some Asian regions (such as Japanese, Korean and China Taiwan Province Province) have long been popular in making bubble water at home, replacing the expensive bubble water bought in the market at a lower price. There are many fashionistas in Japan and Taiwan Province Province who lose weight by drinking bubble water for a long time, and people with intestines and stomach and three highs also adjust their bodies by drinking bubble water for a long time.

The popularity of bubble water in Chinese mainland is slower than that in other countries, so bubble water only became popular in China in the last two years. Domestic bubble water machine can also be found in China in March 20 12.

Acidity and alkalinity

The ph of the body

Q: What is the normal pH value of the human body?

A: The PH value of blood in healthy people is 7.35-7.45.

Q: What should I pay attention to in diet to prevent body acid?

A: The metabolites of meat decomposition in the body are acidic, so you must not eat more, otherwise it will easily cause body acid. Generally, green vegetables are alkaline foods, so eat more vegetables.

Q: What ingredients do you think are good for health?

A: An adult needs about 65,438+0,800 calories a day. Besides the fat contained in staple food, vegetables, meat and eggs, and the heat provided by protein, he also needs some minerals and trace elements, which are contained in bubble water.

Common problems of bubble water

Q: soaking in water can neutralize lactic acid, eliminate physical fatigue, and then help the body adjust to alkaline constitution?

A: Carbonic acid in bubble water is weakly acidic and non-alkaline. Moreover, it has always been a fallacy to adjust the pH of the body by food. Some people like to drink bubble water to refresh their minds, and it is even rumored that bubble water can neutralize lactic acid, eliminate fatigue and build an alkaline constitution? Wang Jianyu, a family physician at Minsheng Cheng 'an Clinic, said: "Carbonic acid contained in bubble water is slightly acidic, and there is no such thing as neutralizing lactic acid! 」

Dr. Wang said: "Food does have acid and alkali, but the medical profession emphasizes that the human body has no acid and alkali constitution, and it is impossible to adjust the acid-base balance of the body by food! He explained that the average person's blood pH is between 7.35 and 7.45, which is slightly alkaline. After metabolism, the pH value will fluctuate slightly, but the body will automatically balance. " If it really becomes acidic or alkaline, it means that the system responsible for balance can't work normally, and you may be acidosis or alkalosis! 」

As for the refreshing effect, it may be because the carbon dioxide contained in bubble water stimulates the taste buds to wake up for a while, but it can't really eliminate fatigue.

Q: Drinking soaking water can promote gastrointestinal peristalsis and relieve constipation?

A: There is no clear research to prove that it can relieve constipation. People with a bad stomach may cause flatulence and gastroesophageal reflux.

Bubble water compresses carbon dioxide in water. Wang Jianyu thinks that for people with bad stomach, it is easy to cause flatulence and gastroesophageal reflux, and it can't obviously promote gastrointestinal peristalsis. He explained that the common cause of constipation is "drinking too little water". Some people think that bubble water can help defecation, but it is actually because they drink enough bubble water, which softens their feces and then easily excretes them, and so does drinking ordinary water.

Xie Bingxin, an attending physician in the Department of Hepatobiliary Gastroenterology, Chi Mei Medical Center, said: "Soaking in water will release carbonic acid gas in the body, which will cause stomach swelling, stimulate gastrointestinal peristalsis and" maybe "improve constipation. However, the study of soaking in water to improve constipation still lacks sufficient evidence. Xie Bingxin added: "When drinking bubbly water with a temperature exceeding 300 degrees Celsius, it may cause obvious stomach swelling, gastroesophageal reflux or stomach discomfort. People with constipation can try it, but don't drink too much, and don't expect too much from soda. 」

Q: The high oxygen permeability of bubble water can prevent skin moisture loss, so it has the effect of beautifying and whitening skin?

A: Soaking in water can't help the skin prevent water loss, nor can it reduce melanin production or accelerate metabolism. Zheng Baishan, an attending physician in the dermatology department of Chi Mei Medical Center, explained that about 70% of the human body is water, and the stratum corneum can prevent water loss, which mainly comes from the interaction between keratinocytes and intercellular lipid structures, so that the skin can complete the task of preventing water loss. "The carbon dioxide contained in bubble water has nothing to do with the barrier function of human skin, so it is nonsense to use bubble water to prevent water loss! 」

As for whether it can be whitened with soaking water? Zheng Baishan explained that if you want to whiten your skin, you must reduce the production of melanin, such as sun protection; Or in order to accelerate the metabolism of melanin, it is necessary to use ointment or laser, and soaking in water has no such effect.

Q: Can pregnant women drink bubble water to relieve morning sickness?

A: Depending on your physical condition or improper drinking may cause more serious morning sickness! The effect of soaking in water to relieve morning sickness is not necessarily effective for every pregnant woman! Xu Yinglun, the attending physician of obstetrics and gynecology at Chimei Medical Center, said that soaking water is mostly ice water, which can eliminate the oral odor that pregnant women are prone to during pregnancy, which is really beneficial. However, according to a study in American Journal of Cardiology 20 15, bubble water can slow down the peristalsis of the stomach, so bubble water may delay the emptying of the stomach, and the increase of carbon dioxide gas will make the stomach flatulent. Excessive drinking or drinking on an empty stomach is more likely to aggravate morning sickness. Mothers who want to relieve morning sickness by bubble water should think twice!

The difference between soda water, soda water and carbonated drinks

Soda, soda and carbonated drinks are basically three concepts.

Bubble water can be divided into artificial bubbles (such as Saint Pei Lu) and natural gas bubbles (such as Parisian water), and the latter is just pure water with bubbles. The above two kinds of soft drinks are boiled and left for one day, but there are still bubbles after pouring a glass of water.

Soda water is pure water with soda, such as canned water sold by Watsons (45 RMB a can). When soda water is boiled, it will turn into pure water in a few hours.

Look at the ingredients list. Both calories and sugar are zero. I don't think long-term drinking will have any effect on my health.

The carbonated drink is Sprite Cola, which contains a lot of sugar.
