1. Chewing promotes saliva secretion and protects oral health anytime and anywhere.
Many people think that chewing sugar-free gum will "stick" food residues in their mouths, but it is not. Studies have shown that saliva does play a protective role. The seemingly ordinary saliva has the functions of cleaning and antibacterial, and chewing can stimulate saliva secretion, wash away food and other residues in the mouth and inhibit the growth of bacteria, which is one of the most powerful preventive mechanisms of the human body. Chewing sugar-free gum for 20 minutes after meals or snacks is a simple and easy way in daily oral health care, which can be done anytime and anywhere. Love your teeth is a good habit worth recommending.
In fact, the anti-caries function of sugar-free chewing gum has long been certified by American Dental Association (ADA), World Dental Association (FDI), Chinese Stomatological Association (CSA) and many other professional institutions at home and abroad. In the newly published Oral Health Guide for China Residents, the Ministry of Health also pointed out that "chewing sugar-free gum can stimulate saliva secretion, reduce oral acidity, and help to freshen breath and clean teeth". As a simple and easy way to protect oral health, you can kill two birds with one stone while enjoying sweetness and delicacy.
2. Chewing helps relieve stress.
Modern scientific research provides physiological experimental basis for human chewing demand and "chewing decompression".
At the end of the 20th century, foreign experts adopted the latest technology of electroencephalogram (EEG), and found that chewing gum can enhance alpha brain waves. However, research shows that alpha brainwaves are a sign that the spirit is in a calm state, and the weakening of alpha brainwaves is closely related to the emergence of emotions such as tension and anxiety. It can be concluded that chewing gum enhances alpha brain waves, thus making the emotional state relatively relaxed. Therefore, experts believe that chewing gum helps to relieve tension. In a survey conducted in the United States, 56% of the respondents agreed that chewing gum helped me overcome my daily nervousness.
The latest research published by Andrew Scholey of Northumbria University in 2009 shows that when mild and moderate acute psychological stress is induced by using experimental procedures, multiple cognitive tasks are completed at the same time. Compared with people who don't chew gum, subjects' self-evaluation alertness is significantly improved, their self-scores of state anxiety and stress are significantly reduced, and cortisol level, an indicator of physical stress state, is reflected in saliva. At the same time, when chewing gum, subjects Therefore, experts believe that chewing helps to relieve tension.
3. Chewing is beneficial to simple weight loss.
People's hunger and satiety responses do not depend entirely on the emptiness and fullness of the stomach itself. Stimulated by chewing, the nerves of mandibular muscles send signals related to satiety to the brain area that controls appetite. After the brain receives this message, the hunger disappears, and it will shout "cut", and then we put down our chopsticks. If you don't chew slowly, your stomach will eat too fast before digestion and absorption, and a series of reactions will be slow, so you will eat too much.
According to a survey jointly conducted by the Japanese Lion Institute of Oral Hygiene and the Institute of Social Dentistry of Tokyo Dental University, 43% of the respondents whose obesity tendency index exceeds 24 are fast food. In addition, 50% people who eat like date palms are prone to obesity.
Nutritionists at the University of Rhode Island in the United States have found that chewing sugar-free gum can not only reduce calorie intake, but also increase energy consumption.
According to the research report published in Appetite magazine, chewing gum before eating snacks can reduce hunger and reduce the desire to eat sweets, thus reducing the calorie intake from snacks by an average of 36 calories.
4. Chewing can relieve bad mood.
Social pressure is getting bigger and bigger, and competition is getting stronger and stronger. Although there is no need to worry about hunger and cold, some negative emotions such as anxiety and depression caused by psychological pressure are getting more and more serious.
It can be said that today's era is an era of pressure everywhere. Work stress, family discord, psychological stress and emotional problems all make us feel stressed and are the source of bad emotions. Many people can't see one thing for their careers and families, and they are physically and mentally exhausted, and it is inevitable that they will be depressed, anxious and angry.
Psychology believes that proper stress and stress response can improve attention and work efficiency to a certain extent, but excessive stress will make the adaptive mechanism in the body fail and lead to dysfunction of the body. How to decompress and how to deal with the tense situation has become the focus of attention.
At the end of the 20th century, researchers used EEG technology to study and analyze the EEG activity when people chew, and found that chewing gum can increase the number and amplitude of alpha brain waves. Previous studies have shown that alpha waves are a sign of mental calm, and the weakening of alpha brain waves is closely related to emotions such as tension and anxiety. Therefore, it can be inferred that chewing gum enhances alpha brain waves, which may make the emotional state relatively relaxed. In addition, the study also found that chewing can improve the signal activity in the hippocampus of the brain, which is closely related to emotional regulation. It can relax the mood by regulating the level of stress-related hormones in the blood. Therefore, experts say that chewing gum may help to relieve tension.
Step 5 Improve your attention and alertness
In the United States, many schools will distribute chewing gum to students before exams to help them improve their alertness and attention.
From 65438 to 0996, researchers from Kyushu University in Japan used PET (positron emission tomography) to prove that chewing can significantly increase blood flow in important areas of the brain by more than 28%. In addition, the study found that chewing can also increase the amount of hemoglobin that transports oxygen in the brain. As we all know, increasing the blood supply and oxygen supply to the brain can improve cognitive abilities including attention and short-term memory. Experts concluded that "moderate intensity chewing may be the most effective way to keep brain nerve cells active."
In 2006, Professor Zhou Xiaolin of Peking University used functional magnetic resonance imaging (fMRI) scanning to find that chewing gum enhanced the activity of some brain regions and significantly improved the blood flow and oxygen supply level of these brain regions. ROI (Region of Interest) analysis showed that chewing gum was helpful to enhance the signal of blood oxygen dependence level (a reflection index of blood supply and oxygen supply to the brain) by 46.3%. He believes that cognitive activities such as chewing, memory and attention use some important areas of the brain (such as thalamus and insula). ), which may be the neural basis of their correlation.
6. Chewing can activate parotid gland hormone secretion and keep young.
With the increase of age, at the age of 30, the subauricular gland, which secretes a lot of parotid hormones, began to shrink. You know, without enough parotid hormone, it is difficult to maintain the elasticity and vitality of blood vessels, skin and other tissues. The most effective and simple way to activate its function is chewing. Chewing can stimulate the subauricular gland and keep the secretion of parotid hormone.
7. Chewing can make you smart.
Chewing can exercise facial muscles, and the masticatory muscles dial a "hotline" to the brain while exercising, so the brain is also activated. Blood is continuously transported to the brain, and information exchange between brain cells is frequent. Due to stimulation, the hormone secretion of the brain increases, and the thinking ability and work efficiency of the brain are significantly improved. According to the research statistics of American medical experts, the IQ of children who chew less is generally lower than that of children who chew food mainly. Genius was thus murdered by ignorant desires.
8. Chewing fully while eating can fight cancer.
Experts show through experiments that chewing for 30 seconds can reduce the toxicity of carcinogens. If you chew food 30 times in one bite and then swallow it every 1 second, congratulations, you have joined the high-tech anti-cancer field.
The secretion of saliva during chewing can reduce the attack of nitrite compounds on cells, change the cell mutation plan, and obviously reduce the harm caused by food additives such as chemical synthetic agents and preservatives. Saliva can also neutralize and eliminate carcinogens in food. Chewing slowly and prolonging life is also a great victory of reason.
9. Chew slowly to reduce the burden on the stomach.
Food swallowed directly without chewing is an uninvited guest in the gastrointestinal tract. The stomach squeezes and rubs hard to make those big pieces of food smaller, and then quickly pushes them into the intestine. The same is true for successors. Everyone is busy, and the squeezed nutrients slip away unconsciously. Chewing slowly can fully combine food with saliva, which can help and promote food digestion. Chewing for many times can grind food, so that the stomach can enjoy it while working in a relaxed environment. People who already feel upset in the stomach should chew slowly.
10. Saliva is the "self-help pharmacy" of the body.
Saliva is the "health patrol" of the body. Chewing is not only to swallow hard food, but also to produce a lot of saliva. People who chew fully secrete saliva 1. 1~ 1.5 liters a day. Saliva is a "self-help pharmacy" in our body. If you don't chew while eating, it will reduce saliva secretion. Gobbling at dinner is equivalent to being outside the defense scope of this "patrol".
1 1. Chewing can drive away dental caries.
When eating, the mouth is acidic, which is very suitable for the growth of dental caries bacteria, and the calcium and phosphorus on the tooth surface begin to dissolve. After chewing, a lot of saliva is secreted, which neutralizes the acid in the mouth, dental caries bacteria escape, teeth are saved, the dissolution of calcium and phosphorus is also stifled, teeth are invincible, and everything is peaceful.
In addition, the food residue on the surface of teeth and gums is eliminated due to mechanical friction, which accelerates the blood circulation of gums and reduces the occurrence of gingivitis.
12. Chew slowly and lose weight simply.
Obese people in America watch the clock to eat and count the times of chewing. They want to chew more times per meal than before they lost weight by eating slowly. Chew slowly, so that food is digested and absorbed faster, blood sugar rises faster, and it is easier to excite the satiety center. Stop eating as soon as you feel full.
