1: Full chewing during meals and saliva secretion during chewing can reduce the attack of nitrite compounds on cells, change the cell mutation plan, and obviously alleviate 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.

2. 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. Only pay without return, so for a long time, the gastrointestinal tract is in a state of continuous fatigue and prone to various diseases.

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.

3. 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".

4. Keep the youth unchanged.

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.

Chewing promotes facial muscle activity, improves the quality of blood circulation in some areas, and makes the skin active in metabolic exercise, with natural ruddy complexion and few wrinkles.

Full chewing can also stimulate the parotid gland, promote the secretion of insulin, regulate the metabolism of sugar in the body, reduce the blood sugar value, and prevent and help the treatment of diabetes.

5. The more times you chew, the greater the stimulation to the brain, and the smarter the brain becomes.

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.

Only when the teeth are strong can you chew fully. Life exists between the teeth and becomes the beginning of activating the brain. If you want to be smart, go to the dentist as soon as possible.

Step 6 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.

By the way, 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. Also, some kind of protein contained in saliva penetrates into the teeth, which can make the teeth grow strong.

7. Volunteer oral cleaners

There are often many bacteria in the mouth, but the wounds in the mouth are rarely infected, which is also the credit of chewing.

The saliva secreted during chewing contains not only lysozyme, but also other antibacterial factors, such as immunoglobulin. They are natural enemies of many kinds of bacteria in air or water, which can prevent bacteria from staying, prevent them from growing and reproducing, and even kill them if necessary.

8. Chew slowly and lose weight simply

People's hunger and satiety responses do not depend entirely on the emptiness and fullness of the stomach itself, but are controlled by the hypothalamus. When food is digested and absorbed by the stomach, the concentration of sugar and amino acids in the blood will increase. 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.

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.

9: Saliva is the most ingenious "cooking master". There is an ingredient in saliva that can make the taste sensitive, and it can make food more delicious when chewing.
