First answer what xylitol is. Xylitol is a normal intermediate product of xylose metabolism, pure xylitol, white crystal or white powder crystal in shape. In nature, it widely exists in fruits, vegetables, grains, mushrooms and other foods and plants, such as wood, straw and corncob. It can be used as sweetener, nutrient and medicine, and is widely used in chemical industry, food, medicine and other industries. In addition, chewing gum is based on natural gum or glycerol resin, and is made by adding syrup (powder), mint, sweetener and so on. You can eat and play, which is very popular with children and young people. Recent research by Japanese scientists shows that chewing gum can temporarily improve memory. The fittest is like this: most people can eat it. Children should not eat more. Every time 1. No more than 2 yuan in a day. Remember: chewing gum can't be swallowed, and children under 3 can't use it! Saccharin, pigment, perfume, antioxidant, etc. Add it to 1 children's chewing gum twice a day, for a total of 1 time. Under the action of bacteria, it can not only form highly viscous water-insoluble polysaccharide, but also form dental plaque and ferment to produce acid, so that the minerals on the tooth surface can be dissolved and lead to dental caries. Chewing gum also contains plasticizer, which is slightly toxic. In the process of blowing bubbles, you constantly spit out your tongue, stick out your tongue, and habitually chew with one side of your teeth, which will lead to uneven maxillofacial development and dentofacial deformity. It is easy for children to swallow chewing gum into esophagus or bronchus by mistake, which will be life-threatening. Although swallowing is not recommended, xylitol chewing gum can be swallowed completely. Don't worry too much. Didn't anyone accidentally swallow gum when they were children? Most of the gum contained in chewing gum has not been digested, and most of it can be excreted with stool. In addition, you can eat some crude fiber food to stimulate intestinal peristalsis. The doctor pointed out that the inner wall of human stomach is smooth and secretes a lot of mucus. Gum can't stick. If it can't be digested after swallowing, it won't be discharged automatically without surgery. But in order to avoid accidents, it is best not to give children chewing gum, because it is not only useless, but also troublesome if swallowed by mistake. In addition, if children chew gum all the time, they will swallow too much air because of chewing gum. In fact, there are advantages and disadvantages, so take care of yourself. Will things turn against each other?
