When you talk with food in your mouth, it means you don't have manners.
Edit: Also, bits of food can fly out.
The short answer is : the epiglottis is a movable flap of tissue attached behind/under the tongue which blocks the entrance to the trachea (windpipe) when food is swallowed, thus protecting the lungs by forcing the food to pass over the trachea and instead go down the esophagus (food- & drink-pipe) into the stomach. If you talk while eating, and you happen to be a toddler, your Mum will tell you off. If you talk while eating, and you are older than that, people may think you are a bit of a pig.......
When eating a meal yes, but don't talk while there is food in your mouth. That's rude! ;)
People can talk while they are eating, but not when they have food in their mouth. Just ask them politely not to talk with their mouthful. That's it.
It is true that you should not talk while you have food in your mouth and it is not really possible to talk while you are taking a drink of a beverage. You may, of course, talk between bites as long as you have swallowed the food.
We are advised so because while eating some food particles might enter the wind pipe which can lead to choking.
Eat your food slowly. Eat with friends and family. Don't talk too much while eating.
The short answer is : the epiglottis is a movable flap of tissue attached behind/under the tongue which blocks the entrance to the trachea. There is also a sound box called Larynx which sends out vibrations when we talk and due to this vibrations the flap opens and sometimes food goes inside and we start coughing. If you talk while eating, and you happen to be a toddler, your Mum will tell you off. If you talk while eating, and you are older than that, people may think you are a bit of a pig.....
Allow the crystal to ring. Don't talk while eating!
If you talk or laugh while eating since your talking or laughing your trachea opens so that you can make sound and if you swallow something it will go down your trachea and you will choke.
The only time when your airway is blocked is when you swallow your food so you can breathe while eating.
Talk to your vet.
Food while an animal is eating.
It's considered rude to talk when you're eating because when you open your mouth, it exposes an image of chewed up food that isn't pleasant to look at.
