 Eating with your mouth open actually makes your food taste better. Forget manners, research shows that open mouth chewing releases the aroma of the food through your mouth to your nose, boosting your senses. It's like swishing around wine in your glass before you drink it, only with food. And the louder you chew, the more you'll enjoy the food. Science says so. But be warned, you may get some dirty looks at the dinner table.
