Does Chewing Too Little Affect Brain Function?

   Do you eat quickly? The kind of speed where you finish a meal in ten minutes, or even wolf down a burger in three bites? Don't be embarrassed to admit it—many people do.

Rushing to work in the morning, you down a cup of coffee and a few bites of sandwich; at lunchtime, takeout arrives, and you shovel down your meal while scrolling through your phone, finishing in minutes without noticing; By evening, too exhausted to bother with anything but instant noodles or another takeout order, we skip the careful chewing altogether.

We've grown accustomed to “fast”—seeing meals merely as a means to fill our stomachs, the quicker the better. But what you might not know is that insufficient chewing doesn't just strain your digestive system; it can also, to some extent, affect your brain's performance. Surprising, right? Don't worry, I'll break it down for you.

Chewing is more than just “breaking down food”

Many people think chewing is merely about breaking down large pieces of food to aid digestion. But in reality, chewing is a complex process. It not only mixes food thoroughly with saliva to help digestion but also subtly “activates” the brain.

You can think of chewing as a mini workout for your brain. When we chew, the jaw movements stimulate nerve signals that increase blood flow to the brain—especially areas linked to memory, learning, and attention. In other words, chewing doesn't just help us eat; it also “wakes up” our minds.

Think about it: why does chewing gum sometimes make you feel more alert? That's the chewing action at work. It sends a signal to your brain: Hey, stay alert!"

The Hidden Consequences of Eating Too Fast

Eating quickly and chewing insufficiently may seem harmless in the short term, but long-term, it can lead to significant issues:

Digestive Strain: Food that isn't properly chewed forces the stomach to work harder to process it, potentially causing indigestion over time.

Overeating: It takes time for the brain to register feelings of fullness. If you swallow large amounts too quickly without sufficient chewing, your brain won't register fullness before you're already feeling uncomfortably stuffed.

Reduced Brain Activity: Studies show that consistently inadequate chewing may impair memory and attention. It doesn't mean you'll instantly become “dumber,” but depriving your brain of this “micro-exercise” can dull its responsiveness.

For example, have you noticed that when we're super busy, we often eat on the go or wolf down our food, only to feel sluggish during afternoon meetings? It's not just work fatigue—eating too quickly is also a culprit.

So how many times should you chew?

Some say “chew each mouthful 30 times,” which sounds exaggerated, but the point is to avoid swallowing too fast. In reality, there's no strict rule about the number of chews. What matters more is consciously slowing down.

Here's a trick: Put down your chopsticks or fork. Chew and swallow each bite completely before picking up your utensils for the next one. This action forces you to slow down.

Another method: Choose foods that require more chewing. Examples include whole-grain bread, nuts, carrot sticks, and apples. These foods naturally require more chewing, helping you develop the habit effortlessly.

The “Little Secret” Between Chewing and Memory

Scientists conducted an interesting experiment: one group chewed gum while taking a memory test, while the other did not. Results showed the gum-chewing group reacted faster and maintained better focus. While gum isn't a miracle cure, it demonstrates that chewing genuinely stimulates the brain, sharpening its focus.

So next time you need to concentrate—whether preparing for a long meeting, studying, or writing a report—try chewing some gum. It might not make you smarter, but it can certainly help you stay alert.

How to incorporate more “chewing” into daily life?

We all understand the principle, but with life's fast pace, many still unconsciously grab fast food and eat quickly. So how can we cultivate the habit of slow chewing? Here are a few tips:

Avoid scrolling on your phone while eating: Distractions make you eat faster subconsciously. Try focusing solely on your food—even just ten minutes can feel more satisfying.

Prepare snacks that require chewing: Nuts, baby carrots, or celery sticks. Compared to chips, they're healthier and demand more chewing effort.

Savour the flavors: Treat chewing as a “tasting” process. You'll discover more nuanced flavors in familiar foods when you chew slowly.

Don't rely solely on liquid foods: Soups, smoothies, and milkshakes are convenient, but long-term dependence reduces chewing opportunities and diminishes mental stimulation.

Modern life moves fast, and efficiency is prioritized everywhere—but eating shouldn't be about speed alone. Slowing down eases your stomach's burden and gives your brain a chance to engage.

Next time you eat, try a small challenge: chew a few extra times and see what changes. You might find not only that your food tastes better, but your mind feels clearer too. Remember this: Chewing is the simplest way to nourish your brain. No gym, no expensive supplements—just take the time to chew a few extra bites at every meal, and you'll be quietly boosting your brainpower.
