Healthy Crunchy Snacks to Beat Those Potato Chip Cravings

All you have to do is open the can and eat the chips, one at a time. As you do so, you tell the researcher if you can perceive any difference in crispness from one chip to another.

You bite, and crunch. Bite, and crunch. And yes, come to think of it, some of the Pringles are considerably fresher and crispier than others. How fascinating!

Here’s something you need to know about Pringles: they’re identical. Formed from a uniform slurry and cooked under strictly controlled conditions, these chips are as close to clones of one another as any entities can be. So there’s no way some of them are fresher or crisper than their fellows. Something else is going on.

What’s going on, you discover months later when you reach into your mailbox for volume 19 issue 5 of the Journal of Sensory Studies, is that the researchers were messing with you by adjusting the volume of your headset, which was broadcasting the sound from the microphone in front of your chip-eating mouth. The lower they turned the volume, the soggier and staler the chips seemed to be. The higher the volume, the crunchier and fresher. And the crunchier you thought the chips were, it turns out, the more you wanted to eat.

A Preference for Crunch

Food manufacturers and marketers have known about the importance of crunchiness for consumer pleasure — and addictiveness — for decades. In the 1960s, Lay’s potato chips slogan was, “Bet you can’t eat just one.” And they almost always won that bet.

Even lab rats prefer crunchy potato chips to the standard rat chow scientifically formulated to meet their every nutritional need. Like us, rodents can get addicted to the sensation of chomping on something crispy, leading to what the German food chemistry researchers alliteratively termed “hedonic hyperphagia,” or what you and I might call “stuffing our faces.”

This stuff has huge economic consequences for the food industry, too. So much so that in the 1980s, Frito Lay was spending upwards of $30 million a year on research into food palatability at its Dallas, Texas facility. That included a $40,000 machine that simulated the human mouth and provided a definitive answer to the question, “What is the ideal breakpoint, in pounds of pressure per square inch, for a potato chip?” (According to Michael Moss, author of Salt Sugar Fat: How the Food Giants Hooked Us, it’s four pounds.)

My Potato Chip Story

I’m no stranger to the allure of a good potato chip. When my twins were nine years old, the older one (by six minutes) was a potato chip fiend. When I brought out a bag of organic Kettle chips, I’d try to limit him to five chips. Instead, he’d grab 10 or 20, or rouse himself to full tantrum mode if I intervened. Sometimes, this ended with him in his room, door locked, as he consumed the entire bag in defiance.

At the supermarket, he’d maneuver us to aisle four and engage in a Defcon 5 meltdown if I refused to allow the bag into the cart.

When I turned to my wife for advice, she told me the one thing I didn’t want to hear. If I didn’t want to fight our son about potato chips, maybe I should stop bringing them into the house.

Like any addict, I went through a period of mental agony and soul-searching, and eventually admitted to myself that my wife was right; to help my son, I was going to have to help myself first. And that’s what I did. I stopped buying potato chips. And within a short while, the issue was resolved. No arguments. No negotiations. No tantrums. And miraculously, no more visits to aisle four.

But I admit it wasn’t easy for me. Which showed me what the Pringles researchers learned: crispy, crunchy (or “crinchy” as they’re sometimes referred to) foods can exert a powerful hold over us. And the food industry engineers the “crunch factor” in its products to trigger cravings and addictions to extremely unhealthy foods.

So what’s the deal? Why is crunchy food so appealing? And what are some crunchy, healthy alternatives to potato chips, Cheetos, pretzels, and other staples of the crunch-iverse?

Why Do We Crave Crunchy Food?

As I sat down to write this article, I looked at the title and instantly wanted to eat something crunchy. Given my breakup with potato chips, I opened the fridge’s crisper drawer and withdrew a firm, cold carrot, and took a satisfying bite. The pressure of my teeth against the root and the sound and satisfying violence of the bite confirmed to my evolutionary brain that I had found a healthy source of nutrition. Had the carrot been old and limp, that would have signified a root of lesser nutritional value.

Through much of our history, our species survived on fruits, vegetables, nuts, seeds, and probably insects as well. For all these foods, crispness is a reliable signifier of freshness and a better nutritional profile. And a likelihood that the food is free from harmful pathogens like molds and bacteria. So it makes sense that our brains still rely on crackle and crunch as shorthand for “good for us.”

We like foods with all different textures, of course. Variety is appealing in and of itself. But crunchy foods can provide a level of satisfaction that encompasses all our senses. The sound is a key part of our enjoyment, as that Pringles experiment demonstrated. Our language to describe such foods is also auditorily satisfying: “crunchy” and “crispy” are onomatopoeic words, sounding like what they describe.

Even outside of our mouths, sounds can attract us to foods. Think of the three Rice Krispies mascots, named for the noise the cereal makes when served with milk: Snap, Crackle, and Pop. (Wacky trivia tidbit I picked up while researching this article: the voice of Pop in TV and radio ads is currently performed by Tom Kenny, who was also the voice of SpongeBob SquarePants.) And those Frito-Lay scientists also figured out how the ideal bag of chips sounds when lifted off the shelf and placed in your shopping cart (especially when it’s not being drowned out by a tantrum!).

Our crunch cravings may even be psychological. Some Freudians go so far as to insist that crunching, along with the ripping and tearing required of meats and some meat substitutes, actually helps us sublimate our natural aggression and tempers our more violent impulses.

The Problem with Many Crunchy Snacks

If crunchiness was a reliable signal of healthy food back in the day, in the modern world, it’s pretty much the opposite. Unlike our ancestors, most of our consumption of crispy foods is of the processed variety. Chips and other crisps are the most popular snacks in the US, followed by cheese, nuts, and cookies. In addition to potato chips, other biggies in the crunchy category include tortilla chips, pretzels, crackers, and puffs.

1. They’re highly processed.

Not to belabor the point, but these are not whole and fresh plant foods anymore. Most snacks like potato chips are highly processed, with pretty much all fiber removed. They’re loaded with excess sodium, unhealthy fats, flavorings, and sometimes added sugars.

2. They’re addictive.

In fact, they’re engineered to be addictive. We have an inherited preference for energy-rich foods since our ancestors who sought out and pigged out on foods high in sugar and fat were more likely to survive famines and thus pass their genes (and preferences) on to us.

In terms of addiction, puffed snacks like Cheetos may be the perfect storm. Not only are they calorically dense, but because they “melt” so quickly and completely in our mouths, our brains register them as non-caloric and don’t send out any satiety signals.

3. They’re high in inflammatory oils.

Most crunchy snacks are high in corn oil, soybean oil, or canola oil as well. These oils are used because they’re the cheapest; however, they’re often GMO, loaded with inflammatory omega-6 fatty acids, and vulnerable to oxidation and the production of free radicals in our bodies.

4. They’re high in refined sugar and flour.

Many crunchy snacks like cereals, cookies, and crackers are also high in refined sugars, like high fructose corn syrup, or sugar made from GMO beets. Add in refined flours, and these snacks hit our brains like a drug, generating powerful dopamine releases that keep us craving and addicted.

5. They’re high in sodium.

Excess sodium is another means of getting us addicted to crunchy foods. A little salt adds flavor, but the sodium content in many crunchy snacks is off the charts. A two-ounce bag of Cheetos contains 500 mg of sodium, which is about ⅓ of the American Heart Association’s recommended daily limit. Too much sodium is implicated in hypertension, obesity, type 2 diabetes, and many other conditions.

6. They’re full of additives.

Oh, and let’s not forget the additives that render these snacks shelf-stable for geologic timeframes. Preservatives, colorings, and other additives of questionable safety are turning many of our snacks into time capsules — if we can keep our hands off them, that is. Even so-called “natural” additives may never have been tested for safety, and there’s plenty of reason to suspect they may not be great for us.

And although many processed crunchy snacks are originally made with plant-based foods (mainly potatoes, corn, and wheat), they lose most of their nutritional value during processing. In general, the further a food product is from its natural form, the less it retains its healthful nutritional properties.

Manufacturers may try to “healthwash” their products by touting the nutrients returned to them via fortification and enrichment, but these processes add back only a small number of nutrients. And they certainly don’t make up for all the nutrition that’s been lost by hyper-processing.

7. Ingredients are often low-quality

To maximize profits, manufacturers will source the cheapest ingredients for their products — many of which are low in quality and nutritional value. Thanks to government food subsidies, the price of processed foods in the US has decreased by a whopping 20-30% over the last four decades. (An additional tragedy here is that millions of people who live in poverty and have access only to convenience store food in their “food deserts,” have come to depend on these cheap, unhealthy calories in order to survive.)

Healthy Crunchy Foods

Remember the notion that we like crunchy foods because crunch once signified “good for us”? Well, there are still plenty of opportunities for healthy crunch in the modern world. Here’s a short list of raw foods, minimally processed foods, and nonprocessed snacks to turn to when you need a snap, crackle, or crunch in your mouth:

• Apples
• Celery
• Carrots
• Jicama
• Peppers
• Cabbage & kimchi
• Brussels sprouts
• Broccoli
• Cauliflower
• Radishes
• Water Chestnuts
• Cucumbers & pickles
• Snap peas
• Nuts
• Seeds
• Popcorn (only healthy if you don’t put unhealthy things on it!)
• Rice Cakes

How to Make Crunchy Snacks

You can also “crunchify” some foods and snacks by how you cook them. Baking, roasting, broiling, and air-frying are common methods, although any heat that removes moisture without burning can do the trick.

To add flavor to your crunch, you can use spice mixes and seasonings. For example, bake kale and other veggies into chips in your oven without oil. Sprinkle garlic powder, smoked paprika, and/or nutritional yeast on top for an umami and cheesy taste.

You can also remove the water from fruits and vegetables by dehydrating them at low temperatures for a longer time, using your oven or a dedicated dehydrator (This is one of our favorites).

You can make your own crackers, too, giving you full control over the kinds and quality of ingredients: whole grain, nut flours, and high-quality oils (if you choose to use them at all), and zesty seasonings in place of excessive salt.

You may not think of cooked beans as crunchy, but it’s easy and quick and inexpensive to toss your chickpeas or white beans with spices and bake them until crispy. They make great snacks on their own, or as a mouth-pleasing addition to salads.

And if you’re a fan of crunchy breakfast cereals, without the processed ingredients, there’s always homemade granola, with dried oats, nuts, fruit, and seeds coated in a sweet date paste and baked until crunchy.
