Chewing slowly can not only promote the digestion and absorption of food, but also have many benefits.

First, it can protect the stomach: chewing slowly can increase the secretion of saliva. After protein in saliva enters the stomach, it can react in the stomach to form protein membrane, which plays a protective role in the stomach. Therefore, people who chew slowly when eating are generally less likely to get digestive tract ulcers.

Second, it can prevent and treat dental diseases: chewing slowly can fully adjust the physiological function of the oral cavity. Chewing can promote the changes of keratin on the surface of gums, accelerate blood circulation and improve the disease resistance of gums. Because food is chewed repeatedly in the mouth, the tooth surface is repeatedly washed by saliva, which enhances the self-cleaning function of the tooth surface and helps to prevent and treat dental diseases.

Third, you can go on a diet to lose weight: when food enters the human body, blood sugar will rise to a certain extent, and the appetite center of the brain will send a signal to stop eating. But when eating too fast, when the brain signals to stop eating, it often eats too much, while chewing slowly is conducive to dieting and losing weight.

Fourth, it can be beautiful: chewing promotes facial muscle activity, improves local blood circulation, and improves skin metabolic activity, thus reducing facial wrinkles and rosy complexion.

5. Delaying mental decline: Chewing slowly can exercise facial muscles, increase brain vitality and prevent brain aging and Alzheimer's disease.

Sixth, it is beneficial to cancer prevention: medical scientists have found that oxidase and peroxidase in saliva can eliminate the toxicity of some carcinogens. When some foods containing carcinogens enter the human body, saliva is the first line of defense of the human body. Some medical scientists believe that the high incidence of cancer in middle-aged and elderly people is related to poor chewing ability. Cultivating good eating habits and chewing slowly for 30 times (about 30 seconds) per meal will help eliminate carcinogens in food.

Seven, contribute to longevity: Studies have confirmed that the salivary glands of the human body secrete a parotid hormone while secreting saliva. This parotid hormone can be absorbed into the blood by the body weight and has the effect of resisting the aging of the body tissue. Chewing slowly can stimulate saliva secretion. When the amount of saliva secretion increases, the secretion and absorption of parotid hormones also increase, thus delaying the aging of the body.
