When you chew,   flavor compounds from the food  to the back of the mouth. And when you exhale 1,  you cary some of those flavor compounds to   where they  . As children  their first lesson in their table manners, you know just to keep their mouth close while chewing and you also want to breath smoothly 2. It’s M.N. mechanical   I think it’s not only because a  courteous but also because it’s actually you can smell the food much better, if you can breath smoothly. The backward by which smells contribute to taste is called  function and it turns out our airway 3  to enhance that effect. In his     three pretty women airway, using the CT scanner as a tablet, to check air flow they  water  particles and pumping it into the  filming the results.


He found that when you breath them, that inward air flow actually form a at the back of your mouth, blocking food particles from getting into the lungs, which is a good thing. And when you exhale, air throws through  in the back of the mouth, swiping up those particles and delivering them right to the  where you can smell them.
The results appear in the    national  of science.
Now there is a way to     system. Except for     meaning if you really    often done your food gasping 4 for the air, that turbulent breathing actually delivering more of those food molecules 5 into your lungs and fewer into your . In other words, your mother is right all alone. Keep your mouth shut and don’t  the food. You’ll cut the chance of chewing and enhance the taste of the meal.
