  • Do you have a friend who justinhales their food?

  • You know what I mean?

  • Like, you've had one bite and their whole burrito is like gone?

  • What are you doing, man?

  • Did you even taste it?

  • Turns out, she probably didn't.

  • Hey there, foodies. Trace here for DNews. Thanks for tuning in.

  • Food is incredible. I love it. I love to eat it, I love to cook it, I love to shop (for) the ingredients!

  • There's nothing worse than spending hours shopping, prepping, cooking, and serving, just to have somebody scarf the whole thing in three bites.

  • And a new study confirms what I knew in my little foodie heartpeople who eat super fast, don't actually taste their food, not really.

  • The study was published in the Proceedings of the National Academy of Sciences under

  • the appetizing title, "Optimal directional volatile transport in retronasal olfaction,"

  • because science, while great at mise en place, has no sense of presentation. Translating

  • the title into layman: they wanted to know how smells got to our nose, from the outside

  • or the INSIDE. And their study found, the latter was actually more important. Our tongue

  • tastes five (maybe six) flavors, but food can have any number of smells to add to those

  • perceptions!

  • Using a model of the human mouth, throat and nasal cavities, researchers found when we

  • inhale through the nose, we create an "air curtain" which keeps volatile -- or airborne

  • -- molecules from going into the lungs. But, when we exhale, food volatiles trapped in

  • the back of the throat swirl upward into the nasal cavity, where we sense them with our

  • olfactory systems!

  • If you eat fast, the air curtain doesn't form, the volatiles don't have time to get trapped

  • in the back of your throat, and thus you don't smell and taste together!

  • There's definitive science for slowing down to savor a meal, for sure.

  • Sometimes, you just want a good scarf, a satisfying guzzling of comforting carbohydrates can make

  • us feel really good once in a rare while, but making a habit of it is the dangerous.

  • This MAY be supported by a 2006 study of nearly 5000 people in the Journal of Epidemiology

  • which found, the rate of food intake heavily correlated with rate of obesity!

  • And another study in the Journal of American Dietetic Association discovered, when people

  • eat fast, they take in more calories, but feel less satisfaction from their meal!

  • If you look at how complicated our alimentary canal really is, this makes more than a mouthful

  • of sense.

  • The stomach is a highly connected organ in the human body. It has a direct connection

  • along the vagus nerve right to the brain stem. When you put food in your belly, the stomach

  • has mucosa and muscles which detect the mechanical feel and overall volume of food, as well as

  • how much the stomach compressed or stretched. When it's empty, a hormone called ghrelin

  • is secreted -- called the hunger hormone, to trigger appetite. Once you eat, the stomach

  • stretches, and ghrelin is suppressed; causing your vagus nerve to signal your brain stem

  • and that signal tells the intestinal train to get moving!

  • Obviously, this is SUPER simplified, there are hormones, enzymes and nerves being tripped

  • and squirted all over the tube running through the middle of your body, but like that corn

  • you ate yesterdaylet's try to get through this in one piece.

  • Next, food moves into the intestine and another hormone called leptin comes into the picture.

  • Leptin is one piece of the nutrient satiation puzzle, the idea that what you're eating has

  • fulfilled your body's nutritional requirement. Scientists don't entirely understand the whole

  • thing, but they know, as food continues through the system, the ileum, colon and rectum will

  • cause secretion of MORE hormones called PYY. A 2006 study found, when mice were deprived

  • of PYY, they wouldn't control their intake, and became obese!

  • So scientists figure, PYY (along with all these other hormones, nerves and triggers)

  • eventually work together to tell your brain OKAY Y'ALL. WE'RE GOOD DOWN HERE. STOP EATING.

  • [[whew!!]]

  • Complicated, no?

  • It's important to be cognizant of the fact, humans are not robots. Many people try and

  • control every aspect of their lives, including eating to take in calories, but being mindful

  • of WHAT you're eating, is just as important as HOW you're eating. When we eat like a machine,

  • our body doesn't have time to suppress or secrete these myriad of compounds, or trigger

  • these processes. It takes time for this sack of meat to know when it's got food in it!

  • So, science says it's best to eat slowly. You'll taste your food better, you'll decrease

  • your portion sizes, and feel better about what you've eaten!

  • You might even lose weight!

  • Don't eat TOO slowif you eat so slow that you stop eating altogether you'd eventually

  • die. Eventuallyever curious about what would happen in between?

  • So was I!

  • How long could we survive without food or water?

  • Don't worry, we DNewsed it.

  • Do you eat fast?

  • Why?

  • Don't tell me you're punching your brother or sister for a seat at the table. Think about

  • it for a second and answer with something introspective, why do you think eat at the

  • speed you eat?

Do you have a friend who justinhales their food?
