STORY AT-A-GLANCE
- Gobbling down your food too fast when you eat may not only eventually require loosening your belt; it may even contribute to the development of metabolic conditions and three of the most serious disease risks
- 1 out of 3 adults in the U.S. have metabolic syndrome
- The longer you chew, the more time enzymes in your saliva have to start the digestion process, and could reduce how much you eat by almost 15%, which over time could represent a significant weight loss
- Creating a calm environment by minimizing distractions and putting down your utensils between bites are two ways you can mindfully approach eating more slowly, for both your nutritional and emotional health
- High blood pressure
- High triglycerides (the fats found in the blood)
- High fasting blood sugar
- Low high-density lipoprotein (HDL) cholesterol
- A large waistline
Japanese Study Shows ‘Wolfing’ Food Down Could Be a Killer
Cardiologist Takayuki Yamaji from Hiroshima University in Japan was the lead author of this study, which involved nearly 1,100 generally healthy male and female participants over a period of five years, the average participant being around 51 years of age. Study subjects were divided into three groups, each categorizing themselves as slow, normal or fast eaters.Over the five years, 84 of the participants developed metabolic syndrome. The result: Your cardiometabolic health could suffer serious harm if you gobble down your food too fast. In fact, it constituted a two-times higher likelihood they would develop metabolic symptoms compared to their slower-eating cohorts, with a spread of a 2.3% likelihood for slow eaters and an 11.6% chance for the fastest ones.
“Eating more slowly may be a crucial lifestyle change to help prevent metabolic syndrome … When people eat fast they tend not to feel full and are more likely to overeat. Eating fast causes bigger glucose fluctuation, which can lead to insulin resistance. We also believe our research would apply to a U.S. population.”
Counting Your Chews; Counting Your Bites
Not many would disagree that bolting food down too quickly can contribute to indigestion, and can sometimes be downright painful. But chewing slowly helps with the mastication-to-digestion process, starting in your mouth.Chewing more slowly helps break down your food faster, and saliva, which contains an enzyme called lingual lipase to help break down fats, helps (quite a bit) when you swallow. The longer you chew, the more time those enzymes have to start breaking down your food.
The process makes digestion easier on your stomach and small intestine, because digestion actually takes a lot of energy. Slowing down makes it easier for your intestines to absorb the nutrients in the foods you eat.
One study demonstrated the point very well: When study participants ate almonds quickly and chewed less (10 times, as opposed to 25 times or 40 times per bite), scientists found that their bodies failed to take in all the considerable nutrients almonds have to offer; the bits simply passed through and were eliminated. For those who chewed the most, the particles (hence the nutrition) were absorbed faster.[7]
If you want to see if chewing more thoroughly may help you eat less, you must first determine how many times you generally chew when you take a bite of food, especially something substantial, like meat or almonds.
Also, try counting how many bites of food you take when eating, like the participants of a Brigham Young University study. Participants were asked to count how many bites of food they took when eating, and then to reduce the number of bites by 20 to 30%. Altogether, the study subjects lost an average of 4 pounds.[8]
Chewing More Slowly Can Help You Eat Less
Remember being told you should chew each bite 32 times (or so) before swallowing? It helps your food digest better, they said. That’s true, as well.As it turns out, intentionally chewing your food better than you probably already do could have more than a few lasting benefits. The featured study indicates that people who are obese have a tendency to chew and swallow more quickly, but they also don’t chew foods as thoroughly compared to people who are slim. Conversely, people who eat more slowly eat less.
“Stretch receptors in the stomach are activated as it fills with food or water; these signal the brain directly through the vagus nerve that connects gut and brainstem. Hormonal signals are released as partially digested food enters the small intestine.
Chewing as an Exercise in Mindfulness
You’ve probably heard that eating to live rather than living to eat helps you adopt a mindset of thoughtfulness to what you put in your mouth. It’s for the purpose of nourishing your body. But beyond that are elements of gratitude.- Sit down at the table and minimize distractions. That means you may, tongue in cheek, have a basket on the sideboard so guests can turn down the volume and place their phones in it for the duration of the meal. Turn off the TV, even if it’s on in the next room.
- Put down your utensils between bites. Breathe. Relax. Look at the faces around you and allow yourself to appreciate each one. If you’re eating alone, every time you take a bite, concentrate on something you’re thankful for.
- Indulge in other peoples’ art of conversation. Listen. Focus on enjoying every aspect of the meal — the people sharing it with you, the taste of individual foods, the flicker of candles, the soft strains of music in the background — everything that helps you engage with appreciation for each moment will enhance the experience.
- Set aside a lengthier amount of time for meals than you typically might; 20 or 30 minutes might be enough, and adopt an attitude of calm that can cue others, even if they’re unaware of it. Make enjoying every bite slowly an intentional act, whatever else might be going on.
Especially at bigger celebrations, when thousands of people wonder afterward why in the world they ate so much, take a breath before picking up your fork, and pace yourself. You’ll feel better, so you’ll be happier, and undoubtedly healthier for it, too.
