Why does used chewing gum stick to clothes? Research work the effect of chewing gum on cognitive processes
Since ancient times, people have been chewing something: the ancient Greeks - the resin of the mastic tree, the Mayans - rubber, the Siberians - larch resin, and in India - a mixture of aromatic leaves. All these “chewing gums” added aroma and freshness to the breath, eliminated unpleasant odors, cleaned the teeth, massaged the gums, and simply left a pleasant taste in the mouth. After the discovery of America, chewing tobacco appeared in Europe and became very widespread.
But this is all background. And the history of chewing gum began on September 23, 1848, when the world's first factory for its production appeared. Factory founder John Curtis I made a chewing mixture from the resin of coniferous trees with the addition of aromatics. But the first attempt to make chewing gum on an industrial scale was not successful. Nevertheless, the history of chewing gum begins its countdown from the founding of the factory.
On June 5, 1869, a dentist from Ohio patented his chewing gum recipe. And in 1871 Thomas Adams received a patent for the invention of a machine for the production of chewing gum. It was at his factory that, 17 years later, the famous “Tutti-frutti” - the chewing gum that conquered all of America - would be produced.
Since then, chewing gum has undergone many metamorphoses: it changed colors and tastes, was produced in the form of balls, cubes, butterflies, etc. and took a very important place in the lives of young people in the second half of the 20th century, and even today remains very popular.
13 facts about chewing gum
1. Chewing gum helps you lose weight. American scientists have discovered that the process of losing weight is facilitated by the use of chewing gum - it speeds up metabolism by as much as 19%.
Chewing gum also helps reduce appetite - chewing stimulates nerve endings that transmit a signal to the brain area responsible for satiety.
2. Chewing gum affects memory. There is active debate about the effect of chewing gum on memory. Thus, psychologists from England have found that chewing gum impairs short-term memory, which is needed for immediate orientation. A person may quickly forget the price of a product that he just held in his hands, or lose the keys in the apartment. According to scientists, any monotonous unconscious movement has a detrimental effect on it, that is, the person becomes more absent-minded.
But scientists from the University of Newcastle (USA) believe that when chewing, the activity of the parts of the brain responsible for memory increases, insulin production and heart rate increase, which means that a person thinks much better. Japanese researchers came to the same conclusion. During their experiment, chewing reduced the time it took subjects to complete tasks; chewers completed them 10% faster than those who did not chew gum.
3. Chewing gum is useful. During chewing, salivation increases, which helps clean the teeth; gums are also massaged, which to some extent prevents periodontal disease.
4. You can chew gum for no more than 5 minutes and only after eating. These are the recommendations of experts. If you chew gum longer, this will lead to the release of gastric juice into the empty stomach, which contributes to the development of stomach ulcers and gastritis.
5. Chewing gum is not a substitute for brushing your teeth. Dentists are confident that chewing gum cannot replace proper teeth cleaning. And even if you don’t have a toothbrush at hand, it’s better to replace it with water and rinse your mouth.
6. Chewing gum does not protect against tooth decay. Caries does not appear on the chewing surfaces, but on the interdental surfaces, so there is no benefit from chewing gum for the prevention of this disease.
7. Chewing gum is harmful to teeth. It destroys fillings, crowns and bridges. Destruction has both a mechanical effect on the teeth and a chemical one - saliva, which is formed during the chewing process, contributes to the formation of alkali, which corrodes fillings.
8. Chewing gum helps you recover faster after colon surgery. This occurs due to the activation of hormones in the digestive system during chewing. Thus, in the UK, when treating patients after intestinal surgery, it is recommended to chew gum for 30 minutes in the morning, lunch and evening. This helps patients quickly return to eating regular food and shortens the postoperative period. This effect of chewing gum is explained by the fact that when chewing, the secretory and motor activity of the intestine is reflexively stimulated.
9. Chewing gum is soothing. It is also a good remedy for stress and improves concentration. “This was proven by English scientists from Northumbria University. Chewing gum plays the role of a “simulator”, allowing many to relive the most blissful moments of their lives, when they were still fed on their mother’s milk. People switch off from anxiety,” explains psychoanalyst Alexander Genschel.
10. Chewing gum does not help get rid of bad breath. It has such a short-term effect that it can generally be called useless.
11. Chewing gum contains a dangerous substance. Aspartame is a sweetener, the substance was invented in 1965 and still arouses suspicion among doctors. The fact is that when aspartame breaks down in the body, two amino acids are formed - asparagine and phenylalanine, as well as a very dangerous alcohol - methanol. In certain concentrations, methanol is dangerous for pregnant women and affects the normal development of the fetus. In addition, methanol turns into carcinogenic formaldehyde.
12. Chewing gum should not be given to children and pregnant women. American neurologist John Olney proved the dangers of glutamate - it is an amino acid and a food additive that enhances taste. He discovered the phenomenon of excitotoxicity: the death of nerve cells due to their overexcitation caused by glutamate and aspartame. According to the scientist, these substances pose a great danger to the developing brain, which means during pregnancy and then until adolescence. The periods when you should definitely give up chewing gum are the last 3 months of pregnancy and the first 4 years of life.
13. There was always chewing gum! Archaeologists have found pieces of prehistoric resin in Northern Europe with imprints of human teeth, which date back to the 7th-2nd millennium BC. The ancient Greeks chewed the resin of the mastic tree, the Indians chewed the resin of conifers, and the Mayan tribes chewed chicle.
What can replace chewing gum?
Resin
The ancient Greeks chewed the resin of the mastic tree to freshen breath and cleanse the mouth. The Mayans used the frozen juice of the Hevea tree for the same purpose - rubber, and the North American Indians chewed the resin of coniferous trees, which was evaporated over a fire. In Siberia, larch resin is still often chewed; at first it crumbles, but then, after chewing for a long time, it gathers into a single piece. It not only cleans your teeth, but also strengthens your gums. They also often chew the resin of cherries, pine trees, spruce trees... But this requires very good and strong teeth. In Soviet childhood, we chewed tar - but this, of course, is the most extreme option.
Zabrus and beeswax
Since ancient times, bee products have been another natural chewing gum. Honeycomb covers - zabrus - are not so convenient to chew, because they crumble in the mouth, but they are very useful, since they also contain bee saliva, honey, and a little bee venom, which bees use to seal the honeycombs. Zabrus contains a high concentration of vitamins A, B, C, E, there are almost all the microelements necessary for humans and a very rare type of fat secreted by bee glands.
Coffee beans
You can freshen your breath not with chewing gum, but with... coffee. You need to chew a few grains, this will remove all unpleasant odors, for example, garlic or alcohol. The fact is that coffee beans contain substances that destroy bacteria - the cause of unpleasant odors. In addition, coffee in small quantities is beneficial - it invigorates and improves memory.
Mint and parsley leaves
Chewing gum is often chewed to silence the stomach, which requires food. In fact, this is a rather harmful activity, since using chewing gum on an empty stomach can lead to gastritis or aggravate existing gastric diseases. To suppress the feeling of hunger and, by the way, freshen your breath, you can chew a mint leaf or a sprig of parsley. These herbs are rich in essential oils and vitamins; they will not cause harm, but will dull your appetite.
Chewing marmalade
A sweet and healthy substitute for chewing gum is chewing marmalade. It is easy to prepare it yourself, and if you use molds or cut out figures from it, then this marmalade can distract your child from chewing gum in bright wrappers.
To prepare chewing marmalade you will need fruit (apples, pears), sugar, water, vegetable or olive oil. You need to peel the fruits, turn them into puree, and cook them with sugar and water. When this mass has cooled and caramelized, grease a wooden board with vegetable oil and place fruit puree on it, cover it with gauze. In summer, this mass can be placed where the sun's rays fall. After some time, cut it into slices.
During the year, the world's population chews about 2 thousand freight cars of chewing gum, and this amounts to at least 100 thousand tons. Who invented this delicacy, how many calories does a piece of rubber burn, how to save yourself from tears with the help of chewing gum, and what is the largest bubble that was inflated from a fragrant plastic mass - in the collection of the site.

They sing songs about chewing gum and make documentaries. It seems that this delicacy, familiar to each of us, has always existed. Not always, of course, but for quite a long time. The prototypes of modern chewing gum can be considered tree resin and beeswax - they were chewed to clean teeth and freshen breath. Archaeologists have discovered pieces of prehistoric resin with teeth imprints that are about 9,000 years old.
Today you can buy a wide variety of chewing gum, both in terms of flavor combinations (for example, with the taste of wasabi, bacon or foie gras) and in terms of functional qualities (energy, soothing, anti-nicotine, etc.).
Story
Mass production of chewing gum was launched by John Curtis in 1848. He evaporated the resin in a cauldron, after which he added various flavorings to it. Such chewing gum did not have an attractive appearance; sometimes it even contained pine needles, which, of course, affected demand.
In the late 60s of the 19th century, inventor Thomas Adams, taking into account the mistakes of his predecessor, decided to produce chewing gum based on rubber rather than pine resin. This chewing gum did not contain any flavoring additives, but sold well.

William Wrigley, a soap manufacturer, noticed that Americans were increasingly purchasing his product to obtain chewing gum, which was offered to customers as a nice bonus. He was not at a loss and in 1891 opened a chewing gum business. In this matter, he quickly managed to supplant Adams' enterprise. This is how the world-famous Wrigley’s Spearmint chewing gum with the addition of peppermint and Juicy Fruit appeared. In 1914, another type of chewing gum of this brand appeared - Doublemint.
It is interesting to note that mint gum became especially popular in America in the 1920s. During Prohibition, drinkers actively used it to mask the smell of alcohol.

Does everyone remember the famous saying of the cat from the cartoon about the parrot Kesha? “It’s a bubble gum!” - exclaimed the red-haired lover of the imported delicacy. So, for chewing gum, from which you can easily and simply blow bubbles, we can all thank Walter Diemer, who, oddly enough, is an accountant by profession. In 1928, he invented bubble gum, a type of chewable treat that could be easily inflated into bubbles (previously it was impossible to inflate them due to the inelasticity of the mass). The recipe for the perfect chewing gum turned out to be: 20% rubber, 60% sugar, 19% corn syrup and 1% flavoring. This invention made chewing gum very popular among children, for whom bubbles became a new form of entertainment. Chewing gum is still made using this recipe today.
Unusual places
In Seattle, there is a wall covered in several layers of chewing gum, up to ten centimeters thick. Any passerby can attach chewing gum to this whimsical surface. The wall has long been a tourist hotspot, although it is regularly included in the list of the most unhygienic and disgusting attractions. Repeated attempts have been made to clear the wall of all these chewing gums, but people continue to stick them. Some people try not just to stick their gum on, but to create some kind of pattern. There are even those who have tried to confess their love in this way! So, if you are planning to visit Seattle, you can also have a hand in such a large-scale creation.
Records
Englishman Gary Duchl wove a chain of chewing gum wrappers 27,250 meters long. You can go crazy!!! With his man-made creation, he landed in the Guinness Book of Records. By the way, it took him a lot of time - about 50 years.
An impressive size bubble of chewing gum with a diameter of 58.5 cm was inflated by a US resident, Susan Montgomery. This is an official record, also included in the Guinness Book of Records. And Chad Fell, also an American, managed to inflate a bubble with a diameter of 50.8 cm without using his hands! Of course, this result is also on the list of records.

Hobbies and interests
In the early 1930s, inserts first appeared in chewing gum packages. The color pictures depicted baseball players and comic book characters. It is not surprising that the inserts almost immediately became collectibles. Some manufacturers offered to assemble a collection of a certain number of pieces and receive a gift for it. Nowadays, collectors are willing to pay a lot of money for especially rare specimens.
Hollywood director David Lynch probably thinks collecting earbuds is primitive and uninteresting, so he collects used chewing gum. For what? Good question! Because, according to him, it resembles the human brain. Strange? More than!
But the Italian designer Maurizio Savini is known for creating sculptures from chewing gum. His extraordinary pink works, made in life-size, made the sculptor famous throughout Europe. This is truly art!
Prohibitions
You can't chew gum in Singapore. The ban was introduced because used chewing gum was being thrown and stuck everywhere, making the city look unkempt. Those who disobey will face serious fines. This also applies to tourists who bring with them more than two packs of chewing gum (anything extra will be considered smuggling). But you can still get chewing gum in Singapore... at a pharmacy. And provided that you have a prescription from your doctor.
Lifehacks
Chewing gum while chopping onions helps prevent tears.
If you want to prevent your ears from getting stuffy on the plane, chew gum during takeoff.
Need to remove gum from clothes? No problem! Place the item in the freezer and keep it there until the gum hardens. After this it can be easily removed.
Fruit chewing gum will help combat heartburn.
If you get carsick, chew some gum and the nausea will go away.
Let's chew
Using chewing gum in 1911, it was possible to avoid a plane crash by sealing damage to the fuselage with it.
Every year, the world's population chews about 100,000 tons of gum.
Chewing gum burns 11 calories per hour.
If you accidentally swallow chewing gum, nothing bad will happen: it will not get stuck in the intestines, but will calmly pass through the digestive tract.
Modern advertising of chewing gum promises us fresh breath, protection against caries, teeth whitening and many other amazing effects. The media debunk these myths and talk about the uselessness and even harmful properties of chewing gum. We've collected some of the most popular facts about chewing gum to prove or disprove them.
Chewing gum prevents tooth decay
Yes and no. This only applies to sugar-free chewing gum. This chewing gum actually removes plaque and food debris, reducing the risk of disease by a third. However, it cannot remove plaque in the same way as a toothbrush. Solution: use chewing gum after meals in conditions where it is not possible to brush your teeth (for example, at work).
Chewing gum whitens teeth
Chewing gum may act as a laxative
Yes. The composition of chewing gum is its main enemy. Chemical dyes, flavors, and sweeteners cause a bunch of undesirable consequences, the most innocent of which are allergies and diarrhea. Sugar substitutes (sorbitol, xylitol, maltitol, mannitol) act as a laxative. In addition, these substances can retain some of the water in the large intestine, causing cramps and flatulence.
Chewing gum helps you lose weight
No. Chewing between meals does not dull the feeling of hunger. Moreover, chewing gum is contraindicated for people with diseases of the gastrointestinal tract. During chewing, we, like Pavlov’s dogs, actively secrete saliva and gastric juice, which can subsequently lead to serious problems (gastritis, duodenitis and other troubles).
Accidentally swallowed chewing gum is not digested, but remains in the stomach for seven years
No. Fortunately, our body does not tolerate such long periods. The composition of the chewing gum really allows it not to be digested, but it can remain in the gastrointestinal tract for a maximum of 1-2 days, until your painful suspicions are interrupted naturally. Most likely, everything will happen even earlier, because sorbitol (a component of many chewing gums), as we have already found out, acts as a laxative. You should only worry if a small child swallowed the gum and it did not come out within the prescribed period.
Chewing gum helps you concentrate
Yes. Japanese scientists have concluded that the process of chewing actually activates areas of the brain responsible for attention and motor functions. Volunteers who took intelligence tests performed on average 10% faster and better on tasks when chewing gum (but without taste or smell).
Chewing gum causes wrinkles
Yes. Alas. Chewing gum lovers, according to the observations of plastic surgeons in the United States, are susceptible to the formation of wrinkles around the mouth. Excessive tension in the facial muscles leads to gradual deformations in the skin, the skin loses its elasticity and wrinkles form. Therefore, you should not get carried away with chewing gum if you want to maintain healthy skin.
Of course, chewing gum can be beneficial in some situations. For example, if you feel sick in a car, chew gum and the nausea will go away. Chewing gum also helps relieve stuffy ears on an airplane.
But if you suffer from periodontal disease, have problems with tooth mobility, or use dental appliances, you should absolutely not use chewing gum, as chewing gum can contribute to tooth decay.

Introduction.
Everyone chews gum - both children and adults. Demand for it does not depend on fashion or time of year and always remains stable. Today, in the homeland of chewing gum - in the USA - more than 100 varieties of chewing gum are sold. Every year Americans spend $2 billion on chewing gum. The average US resident consumes 300 pieces of gum per year.
In Russia, the most chewing group of the population is a group of schoolchildren. Every 3 schoolchildren chews from one to 3 hours daily, which does not leave much to be desired.
What causes this addiction among people to chewing gum? Each person chews for his own purposes. The majority of people use chewing gum to freshen their breath. The smallest amount is chewed by inertia. And only a negligible number of people give up chewing gum.
Propaganda also influences the minds of large audiences. Everyone is familiar with the advertisements for “Wrigley” and “Dirola” chewing gum and many others: we see them on TV screens, the pages of newspapers and magazines, and advertising posters. Small packs of chewing gum are a big business. However, there was no detailed information about this product: consumers know no more about it than advertising allows. – That is why this topic became the object of my attention.
However, if people do not reduce their use of chewing gum, then perhaps in 50 years planet Earth will be called the chewing gum planet.
In my research work I set myselftarget - identify the effect of chewing gum on human cognitive processes.
To achieve my goal, I set myself certaintasks:
Study the history of the origin and use of chewing gum.
Study the composition of chewing gum and establish the effect of harmful substances contained in it on the human body.
To identify the effect of chewing gum on cognitive processes.
Determine the reason for using chewing gum.
The study was conducted on the basis of municipal educational institution secondary school No. 23 of the Oktyabrsky district of the Rostov region in 2009.
II . The effect of chewing gum on cognitive processes.
The history of chewing gum.
Humanity's passion for the process of chewing has been known since ancient times. This is confirmed by archaeological finds dating back to the Stone Age. Pieces of prehistoric resin with imprints of human teeth have been found in Northern Europe. They date back to the 7th-2nd millennia BC. For centuries, the Greeks chewed mastic gum, which was obtained from the bark of the mastic tree, a bush-like plant found primarily in Greece and Turkey. From the Indians of New England, American colonists learned to chew the rubber-like resin that forms on spruce trees when the bark is cut from them. Chunks of spruce gum have been sold in the eastern United States since the early 1800s, representing the first commercial form of chewing gum in this country. Sweetened wax became popular around the 1850s and subsequently greatly surpassed spruce resin in popularity.
The modern variety of chewing gum first appeared in the late 1860s, when it was introduced to the United States.chicle . Chicle is made from the milky sap (latex) of the sapodilla tree, native to the tropical rain forests of Central America. Improvements in production methods for this product led to the birth of a new type of industry.
The twentieth century is so far the only century in history from the beginning to the end of which humanity chewed gum. This product was invented only a little over a hundred years ago, but by the beginning of the 20th century it had become a popular pastime for which millions of people willingly paid money. Chewing gum turned out to be a real commercial miracle. And to a certain extent, even a commodity through which the history of the twentieth century can be told.
It seemed that humanity had acquired a new “fad” only for a while, until the eccentric fashion disappeared. Fate, however, decreed differently. Did William Wrigley know, did other pioneers of the “chewing industry” know that that same trifle, “something for something,” as they once called their product, would remain the favorite pastime of millions of people, turning into an object for many for many years? essentials?
New inventions formed a new world community in which people were connected by invisible threads of preferences and tastes. Being in form a tool for the socialization of people, chewing gum introduced an element of personalization, giving a way to look at the world from your own, unique position. Chewing gum is the closest thing to a person: what could be closer than what is in the mouth? Even in a pack, records are individuals, being separate from each other. Each of them is dressed in its own candy wrapper, and each has its own destiny.
Chewing gum composition.
Chewing gum is a means of improving oral hygiene by increasing the amount of saliva and the rate of salivation, which helps clean tooth surfaces and neutralize organic acids produced by plaque bacteria.
The composition of chewing gum includes: a base (to bind all the ingredients), sweeteners (sugar, corn syrup or sweeteners), flavorings (for good taste and aroma), softeners (to create the appropriate consistency during chewing).
In any chewing gum, the main ingredient is sugar (can also be glucose or dextrose) or sweeteners. They provide 60 to 80% of the chewing gum's weight. All these substances occur in nature. They can be found, for example, in many fruits, such as pears, apples, and also in berries (for example, cherries or strawberries). Sweeteners have less sweetness than sugar (from 0.9 to 0.4, if we take the sweetness of sucrose as 1). Therefore, in order to compensate for the less sweet taste of a sugar-free product, intense sweeteners are used - aspartame or acesulfame potassium. Since their sweetness exceeds the sweetness of sugar hundreds of times, they are used in gum in very small quantities (the content of aspartame in gum is several times lower than in a ripe pear - there is more of it in one pear than in a block of our gum). The only restriction on the use of chewing gum is associated with the use of aspartame - since one of its components is phenylalaline, gum with aspartame is contraindicated for use by patients with phenylketonuria (a rare hereditary disease) - phenylalaline significantly worsens their healthVevent.
Currently, chewing gum containing the sweetener xylitol, the anti-cariogenic effect of which was first shown by research at the University of Turku, Finland, has a predominant effect. Xylitol supplied with chewing gum remains in the oral cavity for a long time and has a beneficial effect.
To give chewing gum flavor, flavorings are added - complex mixtures of natural and artificially produced aromatic substances. To ensure longer-term preservation of taste during chewing, various complex modern technologies are used, such as encapsulation of flavorings (when using this technology, the aromatic substance enters, as it were, into a micro-bag of a neutral substance. When chewing, the bags burst gradually, ensuring the gradual release of the flavor). Flavors are created based on natural oils of various plants and fruits. To prevent chewing gum from losing moisture and becoming brittle, stabilizers that retain moisture, such as glycerin, are used. Sour gum varieties (Lemon Fresh) use various organic acids to provide flavor, such as citric acid. To color the gum, food dyes are used that are safe for use in food. For example, titanium dioxide dye is used to give the Orbit glaze a snow-white color. To produce gum in dragees, ingredients are needed to form a sweetener glaze, such as gum arabic or carnouba wax.
“Choose pleasure.”
If you look at the label of our gum, you will notice that most of the ingredients are accompanied by the E index - the index for the nomenclature of food additives. Most of them are absolutely harmless, and many are familiar to us at home - for example, salt, citric acid, sodium bicarbonate (baking soda), vinegar, etc.
The use of food additives that could be harmful if consumed in excess is strictly regulated. Their maximum content in products is calculated so that during normal consumption it in no way exceeds the threshold dose at which harmful consequences for the body may occur. So, for example, in order to harm yourself by excessive consumption of the antioxidant E320, you need to chew about a kilogram of gum at a time.
No matter how difficult it may be to make out small inscriptions on packages, read them. Chewing gum contains both beneficial and harmful substances.
With a "+" sign
Research has found that replacing sugar with sorbitol, mannitol, and xylitol reduces the incidence of caries. Most chewing gum uses these sweeteners.
It’s good when chewing gum contains calcium lactate: tooth enamel receives this mineral to restore microdamage from saliva.
With a "-" sign
Most often, chewing gum contains dyes - E171, E102, E133, E129, E132, taste stabilizers - E414, E422, emulsifier - E322, which harm the liver.
It's best to avoid chewing gum with "naturally identical flavorings." Incomplete information on the label can already be classified as a sign of low quality product.
Chewing gum made in third world countries uses styrene-butadiene rubber (in Russia it is prohibited for use in food production). Such “chewing gum” can only be determined by tasting: it is usually harder, quickly loses its taste and begins to taste bitter.
« A little about sad things."
Let's start with the fact that the use of “chewing gum” is the prerogative of people with generally healthy teeth and gums. For those suffering from periodontitis, it is better not to chew after eating, but to rinse the mouth with dental elixirs and herbal infusions. Several years ago, some US states, Singapore and some European countries began to ban chewing gum in public places. This is done not only for environmental reasons (during the “chewing gum” boom, the asphalt on the streets of large cities was literally overgrown with “waste”) and not because chewing can distract from work, but also because it is completely harmless and does not contain no narcotic additives, modern chewing gum develops... addiction. Almost the same as for coffee and cigarettes.
Not only do psychologists note that those who constantly chew have a painful addiction, they also note that children who keep chewing gum out of their mouths have a reduced level of intelligence. The rubber band makes it impossible to concentrate, dulls attention and weakens the thinking process. And dentists, in turn, warn that after a couple of years of continuous chewing, diseases associated with periodontal overload begin to progress.
Research conducted by American doctors has shown that there are other side effects:
destruction of bridges, crowns and other dental structures
excessive development of masticatory muscles
increased levels of mercury in the body in people with old fillings from
amalgams
aerophagia (swallowing excess air), etc.. (Annex 1)
One of the most important properties of chewing gum is its ability to increase salivation three times compared to the resting state, and saliva also enters hard-to-reach areas of the teeth.
Chewing gum exerts its effect on oral tissues in the following ways:
increases the rate of salivation;
stimulates the secretion of saliva with increased buffer capacity;
helps neutralize plaque acids;
facilitates the washing of hard-to-reach areas of the oral cavity with saliva;
improves the clearance of sucrose from saliva;
Helps remove food residues.
It is worth dwelling on objections to the use of chewing gum that mention stomach diseases and lesions of the temporomandibular joint. If chewing gum is used correctly, pathology will not occur.Chewing is additional work for underused jaws, an excellent exercise for the gum vessels and a means of combating soft plaque.Based on the results of numerous studies, recommendations can be made for the use of chewing gum. (Appendix 2).
Materials and methods.
Testing logical thinking.
Goal of the work: assessment of logical thinking.
Equipment: stopwatch, a sheet of paper with a picture of number series.
To assess a person’s logical thinking, I distributed sheets of paper with images of number series to four subjects (Appendix 3). Each of the volunteers searched for a pattern in the construction of the series for four minutes and filled in the missing numbers. Then, I repeated this experiment with the same students, but now they performed this task while chewing chewing gum intensively.
Checking your attention span.
Goal of the work: determination of attention span.
Equipment: prepared table, stopwatch, pencil.
To test a person’s attention span, I gave four volunteers sheets of paper with a set of numbers (from 101 to 136) (Appendix 4). The subject had to find the numbers on the proposed table in ascending order and cross out each of them with a pencil. Each of the subjects completed the task individually.
To study the effect of chewing gum on attention span, I distributed chewing gum to the same subjects and invited them to repeat the work done, but with intensive chewing.
Short-term memory.
Goal of the work: determine the capacity of short-term memory.
Equipment: text of 25 words, watch, blank sheet of paper, pencil.
To test a person’s short-term memory, I distributed sheets containing a text of 25 words to four subjects (Appendix 5). And she gave them the opportunity to familiarize themselves with it for 1 minute. Then, each of the students reproduced the words he remembered on a blank sheet of paper in 4 minutes.
Subsequently, we repeated the same process, except that the subjects chewed chewing gum.
Research results.
Questionnaire “Why do we chew?”
When conducting a survey (Appendix 6) among students in grades 6-10, it was found that most students use chewing gum to freshen the mouth, and for some it is caused by habit (Figure 1). Preference is given to Orbit chewing gum. For communication, they choose “non-chewing” interlocutors.
Figure 1 "Using chewing gum"
Among the respondents, many have information about the effects of chewing gum on the human body, but they chew much longer than expected (Figure 2).
Figure 2 "Effects of chewing gum on the human body"
Those suffering from gastrointestinal diseases do not know that chewing gum may be the cause (Figure 3).
Figure 3 "Chewing gum and gastrointestinal diseases"
Despite everything, to cleanse the oral cavity, 100% of respondents prefer using toothpaste (Figure 4); 72% of students believe that chewing worsens memory (Figure 5).
Figure 4 "Oral cavity cleanser"
Figure 5 "Effect of chewing gum on memory"
Assessment of logical thinking.
After assessing the logical thinking of subjects who do not chew chewing gum and comparing the results obtained with the conclusion made after conducting an experiment with it (chewing gum), it should be noted that the logical thinking of the subjects deteriorated by more than 20%, from 75% to 55%. (Figure 6).
Figure 6 "Logical thinking"
Assessment of attention span.
Using the formula for calculating attention span:
B=648: t,
WhereB- amount of attention,
t- operating time in seconds,
I compared the data obtained before and after consuming chewing gum with the standard indicators and found that the attention span of the subjects, as well as logical thinking, decreased at a noticeable level (in 81% of those who did not chew, the attention span was slightly above average, and in 19% of those who chewed the indicator dropped below the average “bar” (Figure 7).
Figure 7 "Assessment of attention span"
3 . Memory capacity estimation.
Using the table for determining memory capacity, I identified the memory category of the subjects based on the sum of points (each reproduced word is worth one point). The results were not surprising: the initial memory capacity of the majority of subjects (94%) falls into the “good” category. With intense chewing, memory sharply deteriorated by 50% (Figure 8).
Figure 8 "Memory capacity estimate"
Conclusions of the study.
After analyzing the results of the research work, I came to an indisputable conclusion:
The use of chewing gum among the students of our school is due to the elimination of unpleasant odor and obtaining a pleasant taste sensation.
Some components of chewing gum can have a negative effect on the human body.
Chewing gum has an adverse effect on a person's thought processes. In particular, this is due to the fact that it prevents people from concentrating when solving mental problems.

Side effects of chewing gum.
APPENDIX 2.
Chewing gum should be used by both children and adults;
It is better to use chewing gum that does not contain sugar;
For adults:
You can chew for no more than 5 minutes before eating. The salivary glands instantly react to the presence of “chewing gum” in the mouth and secrete digestive enzymes. The brain receives a signal: “get ready to eat,” and juice production begins in the stomach. But there is no food, and the acid eats away the mucous membrane. 5 minutes is the approximate time it takes for the signal to travel from the brain to the stomach.
After lunch or snacks throughout the day, chew gum for no more than 15 minutes. This is usually enough to prevent the formation of soft plaque and restore the acid balance.
For children:
You can use it from about 4 years old and only white (without dyes). The child needs to be explained the hygienic purpose of chewing gum and taught to throw it away immediately after it stops being tasty.
Give "chewing gum" only after lunch and afternoon snack and for no more than 15 minutes - otherwise the habit of chewing will become entrenched. Today's constantly chewing teenagers are potential clients of dental clinics. The incompletely formed enamel of “young” teeth is too thin and easily erased.
Do not give chewing gum before meals: the child may lose his appetite and have a bad stomach.
Explain that chewing gum should never be swallowed. It can get stuck in the gastrointestinal tract. There are cases when “chewing gum” became the cause of gastric lavage in hospital conditions.
It must be remembered thatUncontrolled and indiscriminate use of chewing gum many times during the day can be harmful to your health!
