Scientific health, health and happiness. "The old man wolfed down his meals, while the old ladies ate slowly." This is a popular saying in rural areas of Northeast China that advocates fast eating. Obviously demeaning and despising women. In fact, it is also a very unscientific sentence. Beat or chew slowly, which is right? The answer is the latter. Talk about the benefits of chewing slowly: first, chewing slowly can fully grind food, reduce the burden on the stomach and avoid stomach problems. Second, chewing can secrete saliva in the mouth, food and saliva are fully mixed, and digestive juice in saliva can help digestion, so that nutrients in food can be fully absorbed and utilized. Third, chewing can exercise facial muscles, make complexion rosy and reduce wrinkles. Fourth, by chewing slowly, you can improve the blood supply to the brain, thus increasing the blood supply and oxygen supply to the brain and making the brain active. It has been tested that chewing slowly for 20-30 minutes can increase the blood supply to the brain by up to 30%. Fifth, research shows that a bite of food can be fully mixed with saliva into paste after 30 chews, that is, it lasts for about 30 seconds, and the enzymes in saliva can reduce the toxic effects of carcinogens such as nitrite after 20-30 seconds of food contact with saliva, thus reducing the risk of cancer. Sixth, chewing slowly won't make you fat, because when you eat normally for 20 minutes, your brain will get the message of "full" and stop eating. Therefore, people who are afraid of obesity will not overeat and eat more only if they chew slowly. Some surveys have found that there are many slim French women, because they eat politely, and it takes at least 30 minutes to eat a meal. Only by chewing slowly can you taste the delicious food, but you often don't know what you have eaten. Enjoying the beauty of diet is a great pleasure in life. We shouldn't give up relaxing enjoyment just because we eat fast. In ancient Japan, a politician named Tokugawa Ieyasu lived to 76 years old, which was rare in the past. Japanese nutrition experts discovered the secret of his longevity. The conclusion is: No matter how busy he is, even if Enemy at the Gates eats, he will chew every bite carefully and swallow it slowly, taking about 60 bites every meal. If you chew 30 times per meal, you can last about 30 minutes. So, how much time is appropriate for a meal? The opinion of most nutrition experts today is that breakfast should be no less than 20 minutes and lunch and dinner should be 30 minutes.
