Carbonated drinks could compete with the stars of show business - so many misconceptions about them are discussed. Headings as horror movie titles: “Soda dissolves the walls of the stomach!”, “Soda is painted with cochineal insects!”, “Soda causes obesity!” But often big words in the press are not backed up by facts and evidence.
Misconception 1: one chemistry in a bottle
The most common opinion about carbonated drinks is that they contain solid preservatives, dyes and acidity regulators. This misconception is caused by frightening unfamiliar words on the labels and the lack of accessible and convincing information. Recently, we talked in detail about each ingredient in soda. Recall that the main ingredients of carbonated drinks are soda and sugar, and food colors, acids and flavors, and sometimes caffeine, preservatives and other ingredients, are also added to soda.
As for preservatives, using, for example, benzoic and sorbic acids, they increase the shelf life of products by protecting the product from microbial spoilage, thereby reducing the risk of food poisoning. Modern technologies, microbiological control of all components of the drink, special methods of pasteurization and bottling, as well as the most stringent requirements for sanitation and hygiene, allow some large manufacturers not to use preservatives, but also to preserve products for a long time. For example, Coca-Cola does not contain preservatives.
And benzoic and sorbic acids, by the way, are also found in ... berries! But no one considers them to be "solid chemistry."
Aware - means armed!
Misconception 2: E-ingredients are harmful additives
The next misconception is that components labeled E are hazardous to health, so you should choose products without E-ingredients in the composition. In fact, the letter "E" stands for the index of Europe. The E symbol indicates that this ingredient is included in the European register of food additives, and before making food additives in this list of allowed they must have a rationale for their use. Usually this prejudice against “yeshkas” disappears when people learn that E300 is ascorbic acid, a harmless vitamin C. The composition of drinks can be written at the discretion of the manufacturer either using the E-index or listing the full names of the ingredients.
Read more about E-ingredients in a special article.
Misconception 3: soda can “dissolve” the stomach
This myth is a direct consequence of the previous two. People are intimidated: if the bottles are solid chemistry, then what will happen to the stomach if it is drunk? Various experiments with food only add fuel to the fire. The truth is that carbonated drinks, like other food products, contain food acids (most often citric or phosphoric). But their concentration is physiological for our stomach. This means that acids present in carbonated drinks cannot negatively affect the walls of a healthy stomach, because the acidity of gastric juice is 100 (!) Times higher than the acidity of soda.
Debunking the 3 most persistent myths about which water is best to drink in a car
Drinking water in plastic bottles has long been a constant attribute and companion of our lives. Especially during long car trips in the hot season. And car manufacturers are constantly “warming up” interest in this trend, prudently equipping the interior with cup holders for the most common bottle sizes. TV advertising is also not far behind, creating a stable connection between drinking water consumption and a healthy lifestyle.
And in most cases we are talking about still water. Since the consumption of water with gas is more harmful and undesirable compared to ordinary water.
But is this really so?
We will try to dispel the trinity of the most popular and stable prejudices against drinking soda.
Misconception 4: soda is the cause of excess weight
Speaking of diets. Many people think that if there is so much sugar in carbonated drinks, this will inevitably lead to a set of hated kilograms.
But we will be honest: being overweight is always a complex of reasons. This is an unbalanced diet, and a sedentary lifestyle, and metabolic disorders, and many more "and". Not a single product can cause overweight or even obesity.
Sugar (usually used beet or cane) - this is really a traditional ingredient in soda. Moreover, its content in them is comparable to the sugar content in orange juice (about 10%) and lower than in cherry.
Myth # 1: Soda is bad for bones.
There is no evidence to support this theory. Another thing is the famous Coca Cola. One study by American nutritionists found that the secret recipe contains two components: caffeine and phosphoric acid. It can affect the low bone mineral density found in older Americans who regularly drink Cola throughout their lives. In men, such deviations were not found.
But in the chemical composition of ordinary sparkling water, these components are not. Therefore, we resolutely reject the mythical negative consequences of its consumption.
Misconception 5: soda bright colors painted with harmful dyes
Many people believe that strange colors are used in drinks of bright colors, so it is better to buy only transparent carbonated drinks. The food industry uses safe and proven dyes, even if they have unusual names.
For example, orange dye - beta-carotene - obtained from carrots and pumpkins. In Latin, carrots are called carota - carotene. It is also added to drinks when they want to give them a bright orange festive color.
The yellow pigment - curcumin - is extracted from the root of the turmeric plant (the "relative" of ginger). In addition to soda, they also tint cheese, mustard and many other products.
What is soda?
The first carbonated drink appeared almost 300 years ago, in the distant 1767th year. Chemist Joseph Priestley, a native of England, conducted experiments in the course of which a device was developed that saturated water with carbon dioxide - a “saturator”. However, the mass production of carbonated drinks began only in 1783.
The first brand name was Schweppes, which was owned by Jacob Schwepp. And even then, the standard ingredients were included in the drink: sugar, water, a substitute for taste, acid, caffeine and carbon dioxide.
Misconception 7: Cola-type drinks are addictive
This myth is due to the fact that these drinks contain caffeine. But at the same time, few people know that its concentration is so small that it does not cause any tonic effect, and is added only for taste with bitterness.
Therefore, we recommend that you reconsider your view of this ingredient.
Misconception 8: soda destroys tooth enamel
The last very common prejudice about carbonated drinks is related to dental health. Many people believe that soda can cause tooth decay and enamel thinning. In fact, caries is a complex process that arises as a result of the complex effect of adverse external and internal factors, among which, first of all, improper oral hygiene and even congenital predisposition.
In fact, carbonated drinks have no more impact on dental health than other foods and drinks that contain sugar or acids. Much more dangerous from this point of view are products that stick to our teeth, or, for example, candies that we sometimes bite. When we drink soda, the teeth come in contact with the drink for a very short time and are constantly washed with saliva. In this regard, it is important not what affects the teeth, but how long and how. This is a very interesting topic for a separate post, and we will soon share information on how drinks and food affect teeth.

1. The problem is: are sweet carbonated drinks so harmless?
Which child does not like sweet soda? And not only children, but many adults use them. We use carbonated drinks to quench our thirst, not only in the summer, but throughout the year. All carbonated drinks, including Pepsi, are regularly accused of severe harm to health, especially to children. Disputes about the benefits and dangers of these drinks have been going on for many years. I heard and read many myths on the Internet. I became very interested, is this really so? And if you look from a chemical point of view? Therefore, I decided to conduct a small investigation. Where do I start? First of all, I will find out the popularity of the use of these drinks among the students of our school, and then I will deal with the composition of these products. I study their effect on certain substances, find out the acidity of drinks, and most importantly their effect on our health.
Find out what substances are contained in carbonated drinks and how they affect our health.
1. Conduct a survey of students.
2. To consider the acid content in the studied products, to measure the acidity of drinks and to study their effect on certain substances.
3. Consider the content of other components and show their effect on the body.
4. Hypothesis: Is it possible to drink carbonated drinks? I think that you can drink when you want, and these drinks do no harm.
5. Research subject: carbonated drinks.
6. Object of study: Coca-Cola, Pepsi-Cola and Fanta drinks (all from the same producer: Volzhsky, Volgograd Region)
7. Research methods: theoretical (analysis of facts from Internet sources),
empirical (comparison, comparison, conducting a public opinion poll),
mathematical (statistical processing of material)
experimental (chemical experiment).
- Questioning and analysis of the results.
Before choosing an object of study, I conducted a survey of students in my school, from 1 to 11 grades. 69 people participated in the survey.
1. Do you like sweet carbonated drinks?
2. What soda drinks do you drink most often?
3. How often do you drink sodas:
a) several times a day
4. Why do you drink carbonated drinks?
5. Do you know that these drinks contain substances that damage your body?
(all from elementary grades)
Conclusion and Conclusions
The work carried out showed that carbonated drinks are very popular among school students, they are consumed by all respondents. Love 91% of respondents. 83% prefer drinks such as Pepsi-Cola and Coca-Cola, so I researched these very drinks. Most students know about the dangers of drinking carbonated drinks, but still use it.
2. The composition of carbonated drinks. History
Coca-Cola The Coca-Cola drink was invented in the USA in 1886. The main ingredients of Coca-Cola were as follows: three parts of coca leaves per one part of nuts of a tropical cola tree. The resulting drink was patented as a medicine "for any nervous disorders" and was sold in pharmacies. In 1902, Coca-Cola became the most famous drink in the United States. And fifty years after the invention of Coca-Cola, it became for Americans something of a national symbol. Coca-Cola drinks first appeared in the USSR in 1979 during the preparation of the Olympic Games in Moscow. In 1988, Coca-Cola entered the USSR market.
The recipe, although it is not exactly known, “The typical taste today's cola gets from the addition of vanillin, citrate oil, clove oil and lemon. The ingredients of my sample of this drink (manufacturer: Volgograd Region, Volzhsky) are as follows:
water sugar (11%) carbon dioxide dye (sugar color IV, E150) acidity regulator orthophosphoric acid (phosphorus 170 ppm) caffeine (140 ppm) natural flavors. However, during the trial in Turkey, information appeared that food additives also included cochineal insect extract, which caused a scandal, including the fact that some religions prohibit the consumption of insects. "
Pepsi Pepsi-Cola or just Pepsi is a non-alcoholic soft drink sold all over the world. The main competitor of Coca-Cola. The main ingredients of Pepsi Cola are: Sugar, water, caramel (baked sugar), lime juice, phosphoric acid, ethyl alcohol, lemon oil, orange oil, cinnamon oil, nutmeg oil, coriander oil, petigrene oil.
That is, in Pepsi there is no vanillin and clove oil. But sugar is more than enough there. Therefore, the effect on health is almost the same. According to one version, the name "Pepsi" Caleb Bradham derived from the word dyspepsia. According to another, from the substance Pepsi contained in Pepsi. Dyspepsia is a violation of the normal activity of the stomach, difficult and painful digestion. Fanta (manufacturer: Volgograd Region, Volzhsky) includes: purified sparkling water, sugar, orange juice 3-%, acidity regulator citric acid, natural flavors,
stabilizers (glycerol and resin acids esters, guar gum), beta-carotene dye. The biological value of carbonated drinks can be enhanced by fortification. The basis of carbonated drinks is carbonated drinking water. The variety of the assortment of carbonated drinks is due to the types of auxiliary raw materials, which include fruit and berry juices, syrups and extracts, sugar, sorbitol, fruit drinks, grape wines, tinctures, flavors, food acids, colorants, etc.
The composition of carbonated drinks includes various additives: acidity regulators, sweeteners.
The acidity regulator E-330 is a common citric acid used to give a pleasant sour taste. Citric acid does not irritate the mucous membranes of the digestive tract and is approved for use without restrictions. Another acidity regulator - potassium citrate E-332, is also approved for use and meets all hygiene standards. Unfortunately, other substances, for example phosphoric acid E-338, can also be used as acidifiers. The sweetener E-951 is aspartame, which is used as an artificial sugar substitute. It is about 200 times sweeter than sugar, but compared with it does not contain carbohydrates and calories. Thus, the composition of carbonated drinks includes acids: citric, carbonic and phosphoric.
Sugar color IV, E150d, obtained by the "ammonia-sulfite" technology - a natural or identical to the natural dye of brown color. It is a powder, a thick liquid or a solution of dark brown color, bitter taste with the smell of burnt sugar.
Approved for use as a dye.
Sugar color is insensitive to the effects of light, temperature, oxidation. It can be used for coloring products: strong porter, cola, chocolate, seasonings to make the meat sauce brown, jams, confectionery.
Carbon dioxide in soda comes into chemical interaction with water and dissolves quite well in it. Used as a preservative. On the product packaging it is indicated under the code E290. It is believed that it is due to the bubbles that soda quenches thirst well. Others, on the contrary, believe that the mechanical action of the bubbles causes discomfort in the mouth. Carbon dioxide in itself is not harmful, but it causes belching, bloating and gas. This is especially true for people with diseases of the gastrointestinal tract.
Sugar in soda is contained in large quantities, sometimes its content reaches five tablespoons per glass. This negatively affects the functioning of the pancreas and human endocrine system. In addition, this amount of sugar leads to an excess of sugar in the body. This can cause serious health problems such as obesity in children and adults, diabetes and atherosclerosis.
American doctors have long associated obesity with the use of Coca-Cola and other carbonated soft drinks. Overweight tal in America is a real epidemic.
It is proved that soda poorly quenches thirst and is addictive. This leads to the consumption of more fluid, which violates the water-salt balance in the body. In this case, there is a simultaneous change in fat metabolism and an increase in the amount of cholesterol in the blood. And here it’s not far from atherosclerosis and problems with the cardiovascular system.
Currently, many people watching the figure, try to drink only carbonated drinks with the logo "light". They contain sugar substitutes, which reduces the number of calories in the drink. However, they are also harmful. Sweeteners xylitol and sorbitol can cause urolithiasis, saccharin and cyclomat are carcinogens, aspartame leads to allergies and decreased vision.
Some researchers have noted the chemical instability of aspartame. According to them, after several weeks in a hot climate or when heated to 30 degrees Celsius, the bulk of aspartame in sparkling water breaks down into formaldehyde, methanol, phenylalanine and other substances of little benefit. Scientists at the European Ramazzini Foundation’s independent cancer institute in Bologna have stated that aspartame can cause cancer of the kidneys and peripheral nerves. During pregnancy, aspartame can act directly on the fetus, even when consumed in very small doses.
Dyes and flavors contained in soda are broken down in the liver. They can be harmless, but still give a load on the liver. In addition, the liver is also involved in the decomposition of sucrose to glucose and the synthesis of glycogen from glucose. For this reason, soda should not be drunk by people suffering from various hepatitis. Of the dyes, the most common is yellow-5. It can lead to various allergic reactions - from a runny nose and a rash to bronchial asthma. Natural red dye and carmine can also cause life-threatening allergic reactions.
Caffeine in soda is added as a tonic. This causes additional excitation of the nervous system, which is contraindicated in children.
In addition, caffeine is addictive. Although its concentration in soda is not too high, but carbon dioxide enhances its effect several times.
The main preservatives are citric (E 330), potassium citrate (E-332) or phosphoric acid. They lead to irritation of the gastric mucosa, which can cause the development of gastritis and even the appearance of ulcers.
Phosphoric acid, another acidifying agent in drinks, can be irritating to the eyes and skin, although not prohibited. Phosphoric acid leaches calcium from bones. A lack of calcium causes a serious illness such as osteoporosis. Almost all carbonated drinks contain sodium benzoate (E 211). In combination with vitamin C, it releases benzene, which is a carcinogen. In addition, sodium benzoate can also damage human DNA.
- You can clean old coins with a cola (just soak them in a cola and become more shiny)
- Cola can clean the toilet (the effect will be like from some kind of "toilet duckling" - the toilet will look noticeably cleaner)
- Cola is a great way to clean kettles from scale (pour cola into a teapot and leave it for a day and it will be as good as new)
- With the help of cola, you can add beauty to the patterns (when I was at school, we did woodcarving at work lessons and in order to make the patterns more beautiful, I once tried to fill them with cola and the drink ate a couple of centimeters on the board - it turned out a black and white pattern )
- Pour the cola into the burnt pan and bring to a boil - this is how you can achieve the initial state of the pan.
- With the help of Coke, you can age photos (you don’t even need to master Photoshop) - lightly wet the photo with Coke and quickly wipe it off. The effect of aging will turn out, though do not overdo it, otherwise just ruin the photo.
- Cola helps get rid of slugs in the garden. To do this, place flat wide dishes with cola in your garden. They will be attracted by the sweet smell and if they get into the vessel, they will not be able to get out.
- Cola helps unscrew rusted bolts. To do this, soak a rag with cola and wrap around the bolt, then leave for several hours. It will be much easier to unscrew you after the manipulations.
- Coke can clean jewelry. Pour into a glass with cola and lower the jewels there, and then lightly brush over them. Just don’t try to clean jewelry that has any stones in it - it’s very harmful for them.
- Cola is a good hair conditioner. Pour it onto your hair, rinse it and dry it.
- In a number of US states, traffic police always have about 10 liters of cola in a patrol car to flush blood from the highway after an accident. (rumored)
- If you leave a small piece of sausage in a bottle with cola for the night, the sausage will dissolve in the morning!
- Why with the help of cola clean teapots, remove rust and so on? Here is the answer: one of the main components of all carbonated drinks is orthophosphoric acid (an acid of medium strength, stronger than acetic acid, which just clean kettles from scale).
- In 4 days, it can dissolve your nails.
- Acid dissolves mineral substances in enamel, which makes the teeth become fragile, more sensitive and more prone to destruction. The use of drinks with high acidity over a long time (especially in small sips) as a result can lead to the destruction of tooth enamel.
Therefore, dentists recommend drinking carbonated drinks through a straw - then the liquid enters immediately into the back of the oral cavity and does not come into contact with the teeth so aggressively. By the way, it is not recommended to brush your teeth immediately after drinking soda, as additional erosion of teeth can occur due to the presence of acid.
These are some facts from practice. They must be checked, which we will do.
4. Reality. Description of experiments and analysis of results
Equipment and reagents: tubes with Pepsi-Cola and Coca-Cola, sodium bicarbonate (soda), spirit lamp
To check how natural soda is, you need to boil it with soda (the method works for brown, green or yellow in color). If the soda remains the same color - this is the achievement of the chemical industry. If it becomes brown - a natural product.
Result: After conducting an experiment with Pepsi-Cola and Coca-Cola, it turned out that these drinks have slightly changed their color, which means they are a natural product.
Equipment: Pepsi-Cola, Coca-Cola and Fanta cups, dry yeast
To check if there are preservatives in soda, you need to add yeast to the cups and leave them open. If after some time the yeast does not rise, there are preservatives.
Result: After conducting an experiment, we made sure that the yeast rose, so there are no preservatives.
C 6 H12O 6 → 2CO 2 + 2C 2 H 5 OH
glucose ethyl alcohol
Equipment: cups with Pepsi-Cola, Coca-Cola and bun, tweezers, rust-coated nails, scum kettle.
Progress and results:
Pepsi-Cola can clean rust from metal objects and limescale in electric kettles. We loaded rusty cloves into a glass of carbonated drinks; rust did not dissolve. Pepsi-Cola was poured into an electric kettle and boiled, oddly enough, the scum remained unchanged.
Equipment: cups with Pepsi-Cola and Coca-Cola, universal indicator paper
From sources of information I learned that the reaction medium of these drinks can be 2.8 - 3, which means the reaction is acidic. Take a universal indicator paper and moisten in our drinks and compare with the scale.
Result: The reaction of the medium is 5, which means slightly acidic.
Equipment: glasses with Pepsi-Cola and Coca-Cola, candy "Mentos"
Mentos (especially unpainted and unglazed) creates inhomogeneities that serve as centers for the release of dissolved carbon dioxide. Other ingredients that play a role in the chain reaction are aspartame (a sugar substitute), sodium benzoate (preservative) and caffeine in Coca-Cola, and gum arabic and gelatin in Mentos. These ingredients combine well with each other, and if you mix them and add a sufficient number of gas release centers, a violent reaction begins, which immediately releases all carbon dioxide, which leads to a fountain from a cola up to 7 meters high.
I did the same experiment. But there was no such fountain, although the reaction was quite violent. Thus, we can conclude that in our drinks there is no aspartame.
Result: A reaction has occurred since the drink contains phosphoric acid, and the candy contains alkaline components.
Equipment: a glass with Pepsi-Cola and Coca-Cola, tweezers, a piece of beef.
Grab a piece of meat with tweezers and place in glasses with drinks. After 5 minutes, the meat turned white. Left him in glasses for 3 days.
Results: In the experiment, after I pulled out pieces of meat, I saw that in both cases they look cooked. The same thing happens with the walls of our stomach.
Equipment: a glass with Pepsi-Cola, Coca-Cola and fork, tweezers, eggshell.
Acid dissolves mineral substances in enamel, which makes the teeth become fragile, more sensitive and more prone to destruction. Enamel destruction begins already at pH 4.5.
Since the composition of the eggshell coincides with the composition of the bones and teeth, for this experiment we used eggshells. The shell with tweezers was lowered into glasses with drinks and left for 4 days.
Results: No changes have occurred with the shell during this time.
Equipment: Pepsi-Cola, Coca-Cola and Fanta cups, acetylsalicylic acid tablet
I placed acetylsalicylic acid tablets in glasses with drinks.
Results: tablets scattered and curled (flakes formed). I conclude that in no case should tablets be drunk with carbonated drinks.
We also checked that the nails, the blade (leaving them for 5 days) did not dissolve in Coca-Cola and Pepsi-Cola drinks, the aging effect did not occur in the photo.
1. Thus, my hypothesis was confirmed: it is possible to drink carbonated drinks, namely the producer of the city of Volzhsky, Volgograd Region. We have proved that myths cannot always be trusted. Information must be verified empirically.
2. The composition of carbonated drinks includes phosphoric and citric acids, which are added to improve the taste and as a preservative,
3. The acidity of the solution can be determined using indicators,
4. The pH value is a quantitative characteristic of acidity; our drinks had a pH of 5, which is not so bad.
5. In the studied drinks (manufacturer: Volgograd Region, Volzhsky): there are no artificial additives and aspartame sugar substitute, which corresponds to the composition stated on the label.
6. But the acid content in drinks can cause a number of diseases; accordingly, they should be consumed sparingly. Especially they can not be drunk on an empty stomach, because you can simply burn the entire mucous membrane.
After reviewing just a ton of information, I just fell into a state of emotional shock. That I understood for sure that Pepsi-Cola and other soda do more harm than good (which is one piece of meat, cooked before my eyes in a drink). This is what lemonade drinks should be drunk with care. It is necessary to carefully study the composition of the drink, so that it includes only natural products. Follow
To reduce the harm from any soda, including Pepsi, you need to follow simple rules:
1. Drink it cold. The destruction of tooth enamel also depends on the temperature of the drink. In America, soda is drunk more than in Europe, but it is always served with ice, and American children have less tooth damage.
2. Drink through a tube to avoid contact with the can.
3. Limit yourself to one glass 1-2 times a week.
4. Refuse soda if you are obese, diabetes, gastritis, ulcers.
Myth number 2. Cola dissolves meat, copper coins and tooth enamel
This myth has no basis.
Most sweet sodas contain various acids (malic, citric, phosphoric, etc.), which, as a rule, are accused of a terrible effect on coins and tooth enamel. However, the acid content in drinks is minimal and is within the limits allowed by the regulatory documentation, and therefore they are absolutely safe for human health. In addition, the natural acidity of our stomach is sometimes hundreds of times greater than in drinks, so our stomach is well prepared for such an environment.
Thus, it does not dissolve any tooth enamel, much less a coin. In addition, due to its liquid form, drinks do not stay in the mouth for a long time and are not able to harm the teeth. For example, sour Antonov apples affect enamel more aggressively.
Moreover, if the cola contained such an amount of acid that the coins were able to dissolve, then, being poured into aluminum cans, I would not have time to get to the shelves of the stores, dissolving them.
Myth number 3. Sweet soda is full of harmful dyes
This is not true. For example, in Coca-Cola there is only one dye - natural dye caramel. It is thanks to him that drinks acquire their characteristic brown color.
This dye has been used in the food industry for a long time and is found in many products, including soft drinks, pastries, breakfast cereals, sauces, ice cream, etc. Very simplified the production of caramel dye resembles caramelization of sugar at home in the preparation of candies, but in industry this is a controlled process that allows you to achieve the desired color.
The same dye is part of the popular Baikal and other cola drinks.
Myth number 4. A glass of soda contains 20 tablespoons of sugar, which means it is very high-calorie
This myth is very common, but to refute it, it is enough to read the labels of drinks.
For example, 100 ml of Coca-Cola contains 10.6 g of sugar. This is about 2 teaspoons. So, 100 ml of a drink contains only 42 kcal, that is, a glass of 250 ml will have 105 kcal (about 5 teaspoons of sugar) - for comparison, the same calories and sugar are contained in 250 ml of beetroot juice.And in the same glass of grape juice already contains 162 kcal, which is equivalent to about 8 teaspoons of sugar.
Myth number 6. Sweet soda addictive
In fact, the composition of any drinks officially sold on the territory of the Russian Federation is fully indicated on their labels, moreover, when registering food and drinks, the composition is checked by regulatory authorities.
Therefore, we can affirm with all responsibility that there are no mysterious addictive components in these drinks.
However, the craving for a glass of sweet soda can be due to its pleasant taste and simple desire to have fun.
Myth number 7. Cola contains worm extract
It is not true. Indeed, there is a natural dye carmine, which is obtained from insects - cochineal, or cochineal insect. However, this dye gives a red, purple color and is not used in the stake and has never been used.
As we wrote above, the only dye that is part of Coca-Cola is natural caramel dye.
As we can see, sweet soda is shrouded in many myths that, when examined in detail, do not stand up to criticism. Our advice is to carefully study the information on the label of drinks and not believe the rumors.
1. Sea water also consists of 96-97% of water, but not only cannot it be drunk, it also has an extremely detrimental effect on the body’s water and salt balance. Conclusion - the article says superficial bullshit.
2. If cola damages copper, how is it related to aluminum? If there is acid in the stomach and acid in the soda, then why does the meat corrode in the stomach, and what about myth in soda? Cola "does not corrode enamel", but "sour apples corrode more", i.e. the stake already seems to have an effect, but the type is weak. Conclusion - to hell with logic.
3. An article on "soda in general", referred to as "other drinks like cola" - generally without a pale. I applaud while standing.
4. Yes, 5 tablespoons of sugar per cup is not 20. Debunked the myth. For 20 spoons, you need to drink 0.8 liters. That's just a liter of soda people can drink (and drink) faster and more often than 10-20 glasses of tea with 1-2 tablespoons of sugar for the same amount. Calorie content and the path to diabetes are our everything.
5. There is a lot of direct connection between what is not revealed. There is no cellulite from cakes - this is all meat and soda. There is no cellulite meat - it's all cakes and soda. In general, see the previous paragraph on calories. The normal component of cellulite is cola.
6. "You sho, they are testing us!" Morphine is also monitored by regulatory authorities. And the desire to use it can be caused by the desire to get rid of pain (for cancer, for example). So morphine is not addictive, yes. Conclusion - on the inapplicable facts, the left conclusion is made, total bullshit is written.
7. The only thing I can readily believe in. Sugar can be more convenient on an industrial scale, it is necessary to fill it with one fig in the cola itself.
Total - an advertising article about a fool who, in principle, can not compare elementary facts, does not see gaps and contradictions in logic, and is ready to joyfully shrug it off. this is a statement.
Myth # 2: soda destroys teeth
One of the most persistent misconceptions. As for the negative impact on tooth enamel, in order to achieve irreversible negative consequences, you need to drink so much that the human body is simply not able to accept. We expect objections: flavors, especially with the addition of citrus aromas, can have a destructive effect.
However, here fears are generally vain.
English dentists from the University of Birmingham found that most flavored sparkling waters have the same corrosive effect on teeth as orange juice (which is known to soften tooth enamel). In their tests, lemon, lime and grapefruit were the most corrosive flavors because they use citric acid for taste in addition to carbonic acid, which is already present in the recipe. But this is only on paper, in practice, fruit sparkling water can affect your teeth, but in the worst case, it is no more harmful than fruit juice (minus sugar, which just worsens the situation).
Myth # 3: drinking soda can dehydrate your body.
According to experts in the field of health policy from the School of Public Health of the United States, drinking sparkling water has almost the same effect on humans, as does regular drinking. With a slight correction: to quench your thirst, soda should drink a little more.
In conclusion, a few recommendations regarding the effective drinking of sparkling water. It is completely safe to use on a regular basis if:
- You do not suffer from bowel disease. Carbonization can aggravate symptoms and cause unpleasant consequences. Such, for example, as bloating.
- Before use, read the composition of the drink. Avoid sugar-flavored varieties. All kinds of tonics or fruit soda can have additional hidden ingredients containing calories, the consumption of which you want to avoid or minimize.
- Do not drink too much lemonade or its analogues with a large amount of citric acid to improve the taste. Remember: citrus flavored drinks are usually the most acidic.
- Leave them for food, and in between, drink either plain water or drinking water with gas.
Myth 2. Dependence on carbonated drinks is not possible.
One of the biggest misconceptions. Soda contains an incredible amount of sugar (up to about 6 tbsp / liter per liter, but it all depends on the manufacturer), which raises blood pressure and stimulates the nervous system, as well as the production of the hormone of happiness.
As a result, a person in 40-45 minutes after drinking the drink has a desire to drink more, and if taken frequently, causes addiction. Thus, soda can be called the most common drug of the 21st century.
Myth 3. Transparent soda is harmless.
Most often, carbonated drinks have a color in accordance with the product that is supposedly present in the drink. To do this, use phosphoric acid, which leaches calcium, which leads to hair loss and diseases of the teeth and gums. But among the various carbonated products there are clear drinks that, logically, should be harmless. However, phosphoric acid is also used for their color, which, when ingested in a liquid medium, destroys it.
After all that has been said, we advise you not to believe in advertising and refuse carbonated drinks. This is especially true for children under 12 years old and people suffering from chronic diseases. We suggest you drink soda only on holidays in the form of an aperitif to alcoholic beverages. And on other days, we recommend replacing them with water with lemon or honey, as well as natural compotes and fruit drinks.

Myth 1. Disrupts digestion.
It is believed that carbon dioxide disrupts the composition of the gastric juice, and the bubbles themselves irritate the gastric mucosa, leading to gastritis. This assumption in the early 2000s was tested by American scientists as part of a randomized blind study. He was attracted to patients suffering from chronic dyspepsia of the stomach and regular constipation.
Some of the subjects drank ordinary water, another part - soda. After 15 days, scientists checked the condition of the participants. And it turned out that people who consumed ordinary water did not change their condition. But those who drank soda, were pleased with the positive changes. Researchers noted that carbonated water stimulates digestion and, with minor disturbances in the functioning of the stomach, is beneficial.
Myth 2. Causes flatulence and a feeling of bloating.
If you drink the drink in small sips, the effect of expansion will be less pronounced. If you drink a liter of water in one gulp, most likely there will be hiccups or burping. In fact, it is impossible to refute this myth, since each person has a more or less pronounced reaction to the use of carbonated drinks.
Japanese scientists decided to evaluate whether this effect has positive aspects. They involved overweight women in the experiment. Participants did not eat anything in the evening, and in the morning they drank 250 ml of plain or sparkling water.
In the group that drank plain water, in the morning women felt hunger, which is completely natural. In the second group, who used soda, the results were different. It was found that a glass of carbonated water of the usual volume of 250 ml in the stomach creates 900 ml of gas. As a result, due to the fullness of the stomach, women felt full, although they did not eat anything. And they did not experience any uncomfortable phenomena.
Sparkling water creates a feeling of fullness of the stomach, which reduces appetite and protects against overeating.
Myth 3. It hurts bones.
So it is, when it comes to cola or sweet soda. A number of large studies have shown that regular consumption of sugary carbonated drinks reduces bone density in women by 30 percent. And adversely affects adolescent bone density, increasing the risk of fractures.
But not a single study speaks of the harm to bones of ordinary water that does not contain additives. And those that were carried out indicate that the cause of bone tissue destruction is the content of caffeine and phosphoric acid in drinks, which leaches minerals from bones. There is neither one nor the other in pure water.
Myth 4. Destroys teeth.
This opinion is based on the fact that carbonated water contains acid (carbon dioxide), and any drinks with acids are harmful to tooth enamel. In 2007, a study of the effects of drinks on teeth was conducted by specialists at the Dental College of the University of Tennessee (USA).
The most harmful for the teeth was a cola with high acidity. Diet Coke, fruit drinks, juices and coffee drinks are recognized as slightly less harmful. There is no water in this list, since its influence has not been investigated.
But you can make reasonable assumptions. Scientists were interested in the acid-base balance of drinks, which in the most aggressive cola is 2.5. Ordinary water is neutral; its acid-base balance is seven. Aerated is slightly more acidic; its balance is five to six units. That is, some harm to the teeth on her part can be assumed.
It is not scientifically proven that carbonated water can harm tooth enamel. But to avoid risk, drink it through a straw for cocktails.
