Why don't you laugh loudly when eating?

Many people like to talk and laugh while eating. Especially the students who eat in boarding schools and collective canteens, whether they eat in the canteen or at home, or go on an outing with their classmates, have shown great interest. When eating, we still make noise and laugh loudly. From the perspective of personal cultivation, this is just a bad habit; But from the point of view of health, this bad habit is very harmful to human body. Chewing while eating is the first step in the digestion process, which is very important for the digestion and absorption of food and the intake of food nutrition. The quality of this process directly affects the development of gastrointestinal function. If you chew enough, you will secrete more saliva and produce more digestive enzymes, which is beneficial to the digestion of food and make the body absorb as much nutrients as possible. If you laugh and talk loudly while eating, you will inevitably turn your attention to the topic intentionally or unintentionally, ignoring the quality of chewing, and sometimes even "swallow dates". If the food is swallowed without good chewing, it will not only directly affect the digestive and absorption function of the gastrointestinal tract, but also add extra "labor" to the gastrointestinal tract invisibly, which is easy to cause gastrointestinal diseases such as indigestion and gastroenteritis. Walking through a door at the upper end of trachea and esophagus is very annoying. Usually, this door is opened for breathing; When eating, food is swallowed, and this door will automatically cover the trachea to prevent food from falling into the trachea. When eating, swallow the food with a loud smile while putting it in your mouth. This behavior of joking and swallowing in parallel often makes this "door" at a loss, and the swallowed food may "go the wrong way" and slide into the trachea, and then "choke" and "choke". The trachea is used for breathing. Only air is allowed in, not solid things. Even if tiny particles like dust enter the trachea, they will immediately cause a strong reaction. By coughing, something that enters the trachea by mistake will be "coughed". Otherwise, you will cough until you cough up. If large pieces of food, such as peanuts and bones, get stuck in the trachea, it will also cause suffocation and death. So, don't laugh when eating, and don't laugh loudly. Of course, it's not that you can't say a word while eating, but that you should eat slowly, chew slowly and swallow slowly. Even if you have something to say, it's best to swallow the food in your mouth before you say it. Don't get carried away and laugh.
