Everyday many of us chew the cud, and do not even think about what kind of benefit or harm it brings to our body.Plenty of choice of goods on store shelves and active advertising leads to the fact that buying a chewing gum, a person is guided only by their own preferences: a company-maker and with what will taste this product.Commercials promise whiter teeth, protection against dental caries, fresh breath, showing Hollywood smiles and thereby causing a positive attitude to the consumption of these products.But is it all harmless?And why a child's parents and teachers insist that children do not chew the cud?

Myth 1. can not swallow chewing gum, and then die.Scientists investigated and disproved this assumption.Contrary to popular belief that chewing gum can "close up" gut, studies have shown that as well as any other object caught in the digestive tract, chewing gum is enveloped in saliva, chemically treated and digested.The benefit of this product is not of course, but too much harm.

Myth 2. Gum protects teeth from caries.One can not prove or disprove this statement.Undoubtedly, chewing gum after a meal, food particles and bacteria, the remaining teeth are removed mechanically.Moreover, the act of chewing causes increased salivation, which creates favorable chemical environment in the oral cavity.But, on the other hand, the remains of food that lingered in tight spaces or holes in decayed teeth, gum only pushes further.The fact that dental fillings fall under the action of chewing gum no extra arguments.

Myth 3. Chewing gum is able to freshen breath.Breathing is an act of inhaling and exhaling.So it refreshed only breath.In the mouth there is a taste of gum and an illusion of fresh breath.But this is a subjective feeling.In fact, bad breath originates much deeper into the digestive tract, while exhaling surrounding hear the smell, and the cud is not able to completely destroy.

And another important fact.Scientists came to the conclusion that those who chew the cud, often encounter problems with memory.While working on the processes responsible for the perception and memorization of information on the hearing, the act of chewing reduces the concentration of attention, and as a result, adversely affect the result.
