History of the appearance of chewing gum.
Well, I'll start my story with the history of chewing gum. So who invented this chewing gum for the first time? It is believed that the cuddle was invented by those same Americans in the late nineteenth century. However, the history of chewing gum dates back more than one millennium. Remember from the course of school history, already in primitive society appeared a kind of chewing gum. In the Stone Age, people knew that if you mix resin and bark of trees, they will get a product that can be chewed, in other words, chewing gum. With her help, they brushed their teeth after eating, or chewed up, in order to arouse appetite, due to the fact that it causes the secretion of gastric juice. I must say that in those distant times, the food of our ancestors was completely different than now. It was very tough, difficult to digest. There were no dentists, like other doctors, then. I do not take into account the priests and wise men. Accordingly, people of the Stone Age had to be very sensitive to their teeth, because with the help of them they ate. To lose the opportunity is, it meant, death. In order to preserve their teeth and the ability to live, people began to use resin mixed with bark of trees for cleaning their teeth. For a more pleasant aroma and taste, a little honey was added to the mixture.
Very developed use of chewing gum was in the Indians of Central and North America. After Columbus discovered America, the European community learned about the existence of chewing gum and about the Indian technology of chewing gum production. However, chewing gum, which we all know, came much later, and it was in the United States that an industrial method for manufacturing chewing gum was invented. To begin with, spruce resin was used for its production, but, because it was very difficult to chew such chewing gum, this technology was abandoned, in its place it was necessary to come up with another, more suitable one. What, in fact, and did not stop to do enterprising American manufacturers. They spent a lot of time trying to find new raw materials, and found it! In the subtropical zone of America grows an absolutely stunning tree - sapodilla. The leaves of this tree are very juicy and tasty leaves. Of these, juice is extracted, which becomes the basis for chewing gum. In its consistency and appearance, this juice is very similar to latex. Later, in this basis, American manufacturers learned to add various substances, flavors, dyes.
In the first half of the twentieth century, American researchers and scientists found that regular chewing gum helps to get rid of the effects of stress and stress, relieves fatigue from the muscles. When the US government learned about this, a decree was issued, in which every US soldier was to be provided every day with a chewing gum. It was after this incident that an image of a steep American soldier chewing a chewing gum appeared in the movie. It is worth noting that then the chewing gum was a more natural product and less harmful to the teeth. Modern chewing gum completely consists of different chemical substances: substitutes, flavors, dyes and other achievements of mankind. The basis, of course, remains the past - natural. Let's try to understand what the regular use of chewing gum can lead to. We continue to investigate the question: "Chewing gum. History of appearance. How to use it correctly. " With the first part of the question, we figured out, and found out how the chewing gum appeared, how the process of its production was being perfected.
According to the advertisement, the chewing gum helps to cleanse the mouth, refresh breathing, improve blood flow to the gums, even contributes to the process of losing weight. Of course, this is all fine if the action of the chewing gum ends only on this. However, recently in civilized countries around the world, and in Third World countries, one can meet a person chewing gum, and does it everywhere: in public transport, in the cinema, at an exhibition, in a museum, at school, at home, at the wheel , in a store, in a word, wherever he happens. However, as it turns out, chewing gum in many countries in different places is prohibited. There are countries in Asia, Europe and the United States, which are strictly prohibited from chewing gum. This decision was taken by the government of different countries because spit out the gum wherever it spoils the appearance of the street, gives an unsightly appearance to the asphalt, the pavement and the streets. In addition, that the chewing gum spoils the appearance of the city, it is addictive. No, of course, there will not be drug dependence on it, it causes another form of dependence, which psychiatrists and psychologists of different countries know well. This dependence is similar to the dependence on movements. So, we continue to consider the question: "Chewing gum. History of appearance. How to use it correctly? "
Harm from the chewing gum.
As I wrote above, some people may have a dependence on the constant chewing of chewing gum. As a result, a form of dependence appears. When a person does not chew gum, he gets the feeling that he seems to be deprived of something, as if he has no clothes on him. A person feels as if he is deprived of an important accessory. Numerous researches of scientists confirm that constant chewing gum in children can reduce the level of their intelligence several times. Regular use of gum leads to the fact that children become inattentive, their reaction becomes weak, the thinking process becomes inert and sluggish. How, in this case, can we talk about intensive and effective teaching of children? I'm talking about the constant and regular chewing gum, which is addictive and addictive.
The next harm that chewing gum causes on our body is the harm that is on our teeth and stomach. A person who chews chewing gum permanently harms his own body. From the constant chewing gum in the body is as follows: the stomach is always in a state of "alertness" to the process of digesting food, but it does not enter the body, as a result, the produced gastric juice begins to negatively affect the mucous membranes. This constant exposure gradually leads to the appearance of gastritis, ulcers and other digestive problems. All this negative impact of chewing gum is constantly confirmed by dentists from different countries. Regular abuse of chewing gum can lead to serious problems and diseases. For example, if the chewing gum is very elastic, then it can cause the destruction of the fillings, crowns. The constant chewing of the chewing gum results in inflammation of the mucous membranes in the mouth and in the intestines. Due to chemical constituents such as dyes, flavors, stabilizers and the like, there are problems with the stomach, with the kidneys and with other internal organs. In young people, the constant chewing of chewing gum also leads to negative consequences. Due to the fact that students and students chew chewing gum constantly, they have changes in the functioning of the chewing muscles, because of this there is a violation of the blood supply to the jaw area. Increases the load on the jaw tissue, on the teeth. They are all the time in suspense. Because of this, at night many young people grind their teeth, erasing tooth enamel, which allows to penetrate into the teeth of any infections. So, we have considered the first part of the question "Chewing Gum. History of appearance. How to use it correctly. " We pass to the last part of the question.
Gum. How to use it correctly.
We figured out how the chewing gum appeared, what harm it can bring to our body, let's now try to figure out how to properly use the chewing gum, without harm to our body. We will use the advice of dentists and correctly perceive information from advertising. So, chew the cud after meal, but, no more than 15 minutes. Then your teeth will not show a touch, and the acid-base balance will be normal. However, very few people follow this rule. Usually, a person takes a couple of pads of mint chewing gum after breakfast and chews them until lunch time, then the story repeats, and so on. You can use chewing gum not only after eating, but also before. In order to stimulate the production of gastric juice, you can chew the chewing gum five minutes before eating, but no more.
Parents should pay special attention to how children chew gum. As I wrote above, the constant use of chewing gum in childhood leads to the fact that they are deteriorating blood supply to the brain, which, in turn, leads to a decrease in attention, impaired care and digestibility of new material. So, explain to your children that you can chew the chewing gum, but only by following certain rules. Drivers also should not abuse chewing gum, as chewing gum leads to a decrease in concentration, which can lead to an accident. Naturally, if the cud is used correctly, then there is nothing bad and harmful in it.
Another point in the use of gum, to which I would like to pay attention. Earlier, when chewing gum was rare, children were more reverent towards teachers and school, chewing gum at the lesson was indecent, so the gum was thrown away before the lessons, and if the student came to the lesson and chewed the cud, this could cause the parents to call the school. Therefore, often, children glued the chewing gum on a chair or under a table. School children grew up, became adults, but they never got rid of this childhood habit. Comrades, let us be educated people, and we will not stick gum in public places or spit it out on the street. There are urns and trash cans, where you can spit out the chewing gum you bored. If you use chewing gum by appointment, do not abuse it, and do not chew for several hours, then you can keep your teeth in excellent condition, and the acid-base balance is normal!
