Chewing gum is a snack we often eat in our daily life. It can refresh our mind and refresh our breath. But recently, I heard that chewing gum for too long can cause cancer. Is that true? How long can you chew gum? Let's have a look.
Why do you spit up gum after chewing for 10 minutes
There are many people who like chewing gum in their life. Chewing gum not only relieves fatigue but also refreshes their breath. Most people forget how long they have to chew it. A recent study shows that chewing gum takes 10 minutes to spit out.
A lot of people chew gum is chewed does not have sweet taste to spit out, chew gum actually also has time request! A new study, published in the journal PLoS One, found that chewing a piece of gum for 10 minutes absorbed about 100 million bacteria. Gum with sugar can backfire. At the same time, the researchers said chewing gum time should not exceed 10 minutes. Chewing gum for too long will change its structure, reduce the hardness of the gum, affect the adhesion of the gum to bacteria, resulting in the adsorption of bacteria released back into the mouth.
Does chewing gum cause cancer
No, experts say that as long as the whole bottle of chewing gum is swallowed, it will not reach the carcinogenic concentration. But chewing too much gum can also have a bad effect. Too much, too long chewing gum chewing muscle always in a state of tension, it is possible to develop the habit of grinding teeth at night. In addition, if teenagers chew gum during their physical development, they may over exercise their masseter muscles, stimulate the development of muscles and bones in the mandibular angle, and finally show a "square face".
Most chewing gum is sweetened with sucrose. When chewing gum, the sugar stays in the mouth for a long time. Cariogenic bacteria in the mouth will use sucrose to produce acid substances, which will corrode the teeth. Second, people who have used mercury containing materials to fill their teeth should not chew gum. Regular chewing of gum can damage the substance in the mouth that is used for filling teeth, research has found. Doctors suggest chewing gum for no more than 15 minutes, and people with stomach problems should not chew gum too much.
The difference between gum and xylitol
Gum contains sugar, xylitol has sweet taste but does not contain sugar. It is a substitute of sugar. Too much xylitol won't make you fat. Moreover, in terms of physical and chemical properties, xylitol is relatively cold, such as seafood, mung bean and other foods. It is not easy to be decomposed by stomach enzymes, and directly enters the intestine. If you eat too much, it will stimulate the gastrointestinal tract to a certain extent, which may cause abdominal discomfort, flatulence and bowel sounds. As the absorption rate of xylitol in the intestine is less than 20%, it is easy to accumulate in the intestinal wall and cause osmotic diarrhea. According to the constitution of Chinese people, the upper limit of xylitol intake per day is 50g. Chewing gum alone should not be a problem, but if you eat a lot of other xylitol food, you need to pay attention to the dosage.
There are saccharin, pigment, perfume, antioxidant and so on in chewing gum. Most chewing gum is sweetened with sucrose. When chewing gum, the sugar stays in the mouth for a long time. The cariogenic bacteria in the mouth will use sucrose to produce acid substances, which will corrode the teeth and cause decalcification of the teeth, thus inducing caries.
