To keep blood sugar levels stable, metabolism running, and weight loss on track, a snack can be one of the best tools in your arsenal. But if you choose unhealthy snacks (aka processed ones that come in packages) then you risk experiencing the exact opposite. Big yikes.
That's why we've rounded up some of the most popular chips, crackers, popcorn, cookies, and snack bars that either have sketchy nutritionals or do more harm than good for your belly. Make sure you're not munching on these truly unhealthy snacks. Instead, stock up on The 7 Healthiest Foods to Eat Right Now.
Now, here are the 35 of the unhealthiest snacks you'll find on grocery store shelves.
Chips
Lay's Potato Chips, Barbecue
These chips are an American favorite. They're not the worst chip on this list with regard to calories or sodium, but they do still contain 10 grams of fat. If six-pack abs are in your sights, regularly munching on these chips may keep you from achieving your goal.
Ruffles Original
Although these may have a more pleasing texture, they're not worth the eye-popping fat content. Save these textured chips for occasional indulgences.
Lay's Potato Chips, Classic

These are so salty and oily, you'll find a coating on both your fingers and tongue after just one. That's reason enough to limit your consumption of this classic snack at the next picnic or sporting event you attend!
Pringles Sour Cream & Onion
The use of various vegetable oils and myriad other additives puts this flavor of Pringles on the naughty list.
Herr's Ketchup Flavored Potato Chips
If you're one of those people who puts ketchup on literally everything, you're probably tempted to indulge in these chips. But proceed with caution. Combining two salty items can only produce one result: sky-high sodium. One serving contains just under 300 milligrams of sodium. Remember, you should try and limit your intake of sodium to less than 2,300 milligrams per day.

Pringles Cheddar Cheese
Similar to the sour cream and onion variety, Pringles' cheddar cheese chips are high in total fat, saturated fat, and sodium. Your best bet is to avoid this, or at the very least, consider them an every "once in a while" snack.
Ruffles Cheddar & Sour Cream
The nutritional profile of these and Ruffles' Original are about the same. However, this cheesy flavor contains two artificial dyes, Yellow 6 and Yellow 5, which a study published in the journal Neurotherapeutics discovered can contribute to ADHD in children.
Herr's Salt & Vinegar

If you take nothing else from this article, heed this—the Herr's salt and vinegar chips have a whopping 490 milligrams of sodium per serving, far higher than any other option on this list. The American Heart Association (AHA) recommends consuming no more than 2,300 milligrams of sodium per day, but they hope most adults will actually consume no more than 1,500 milligrams per day. So keeping this in mind, one serving of these chips is almost one-third of that. Yikes!
Ruffles Baked Cheddar & Sour Cream
These oven-baked chips may boast a lower fat content than their fried counterparts, but they consequently contain more salt—and sodium can derail your weight loss goals.
Fritos Corn Chips, Chili Cheese
One serving of these Fritos costs you 10 grams of fat and 210 milligrams of sodium, both diet demons. They also contain caramel color—which is often found in soft drinks (one of the unhealthiest foods on the planet)—and is believed to be a carcinogen for humans, per a Johns Hopkins Bloomberg School of Public Health study.
Cheetos, Flamin' Hot
Do you know how these spicy cheesy chips dye your fingertips red? Just imagine what they do to your insides. These flaming hot corn puffs are jam-packed with several artificial dyes and ingredients so try and skip as much as possible.
UTZ Red Hot
Spicy foods are notoriously good for giving your metabolism a kick, but these red hot chips are an exception. Riddled with artificial dyes, MSG, and a whopping 300 milligrams of sodium, you're better off skipping this snack.
Microwave Popcorn
Jolly Time Mini Bags Blast O Butter, Ultimate Theatre Style
Although we kept serving sizes consistent for most of the popcorn bags, we made an exception for this one. That's because the bag is marketed as a single serving, so we'd assume people would likely work through the entire thing. Doing so means you'll set yourself back 13 grams of fat coming from inflammatory palm oil. It's not just microwaveable popcorn that does it; check out these foods with misleading serving sizes to see more examples of how you could be duped into consuming more calories than you were initially led to believe.
Cousin Willie's Buttery Explosion
This bag of kernels is a relic of the old days. Before the FDA announced that it was banning partially hydrogenated oils—also known as artery-clogging trans fats—from food, the majority of microwaveable popcorn brands contained this shelf-stable ingredient. Because the ban was enforced in 2018, many brands have moved away from this cardiotoxic ingredient. Not Cousin Willie's. The Indiana-based company serves up 150% of your recommended maximum intake of trans fats—one of the worst foods for your brain—in their standard serving.

Pop-Secret Homestyle
Besides the high sodium and fat content, we were also irked by Pop-Secret's addition of palm oil and vague "natural flavors" to their kernels.
Act II Xtreme Butter
With TBHQ and palm oil, we'd rather not have a snack than munch on this buttery bag of popcorn while watching a movie!
Pop-Secret Double Butter Flavor
It might have less fat than other popcorn brands, but Pop-Secret contains more salt. And it's no secret that a high salt intake isn't great for your heart health.
Orville Redenbacher's Pour Over Movie Theater Butter
Those 14 grams of fat are full of linoleic acid: an omega-6 fatty acid that has been found to be possibly adipogenic, which means it promotes fat storage in our bodies. Luckily, you have the calorie-cutting power in your own hands, thanks to Orville Redenbacher's "Pour Over" butter. Use the flavor sparsely!
Orville Redenbacher's Movie Theater Butter
This might surprise you, but the ingredients of Orville Redenbacher's Movie Theater Butter are the exact same as the "Homestyle" bowl listed below. But because there is more fat and sodium in this recipe, we'd recommend going with the option below if you have to choose one.
Orville Redenbacher's Homestyle
It might be called "Homestyle," but we'd bet you don't have "artificial flavors" or "TBHQ" in your pantry. We do, however, hope you have these healthy pantry staples!
Crackers
Keebler Club Crackers, Original
They're a go-to staple snack when your stomach is upset—but, unfortunately, not so great in general. At first glance, the nutritionals don't seem too bad but since these crackers are considered empty calories, doubling or tripling your serving size (which is pretty easy to do when the recommended serving size is just four crackers!) can lead you to consume 200 calories of a snack that's lacking in nutrients.
Ritz Roasted Vegetable
As the name suggests, this box contains a handful of dehydrated vegetables. The problem is, the main ingredient is still flour and it's bogged down with partially hydrogenated oils and high-fructose corn syrup.
Ritz Bits Sandwiches, Cheese
Time to stop reaching into your tote bag and doling these out to your kiddos—there are healthier options out there!

Cheez-It Original
Cheez-It's lack of fiber prevents these crackers from having a meaningful impact on hunger. If you're going to snack, do so smartly.
Keebler Club Crackers, Multigrain
If you're looking for a plain cracker to calm your tummy, you can find one without preservatives and high fructose corn syrup.
Keebler Town House Flatbread Crisps Sea Salt & Olive Oil
The four grams of fat here come mostly from soybean oil, which the experts are not exactly fans of.
Wheat Thins Original
Wheat Thins rely heavily on refined grains, which means less protein and fiber in each serving.
Cookies
Keebler E.L.Fudge Elfwich
These cookies are double stuffed with fudge, which clearly means double the trouble. And 12 grams of sugar in just cookies is never a good look.
Oreos

This might be your favorite cookie from your childhood, but it's loaded in sugar and HFCS. Plus, the simple carbs aren't doing you any favors, either. Along with the zero fiber you're getting, you'll end up staying hungry, reaching for more and that's not going to help you keep your weight-loss goals in check.
Pepperidge Farm Milano Dark Chocolate
Here, you're getting 11 grams of added sugar in one serving—yes, that's a whole lot!
Famous Amos Chocolate Chip Cookies

The biggest problem with Famous Amos cookies? It's how small they are, as it's way too easy for the calories and fat to rack up as you mindlessly munch away.
Nutrition Bars
Detour Cookies 'n Cream Crunch
If the whopping 350 calories in this Detour bar didn't deter you from skipping it, consider the ultra-long ingredient list.
Balance Bar Chocolate Peanut Butter
Following a protein blend, the second ingredient in this bar is sugar in the form of fructose. A study by the Endocrine Society found that fructose is a major cause of dangerous visceral (abdominal) fat.
Clif Bar Chocolate Brownie
Opt for a Snickers bar over this chocolate brownie Clif and you'll save a gram of sugar!
Zone Perfect Chocolate Chip Cookie Dough
This bar boasts 10 grams of protein and is under 200 calories, so at first glance, it may seem like a good choice. But don't be fooled—it certainly deserves a spot on our list of unhealthy snacks. It contains three different forms of sugar within the first four ingredients listed on the nutrition label. Brown rice syrup and corn syrup are the first two ingredients, which means they're the most abundant. Plus, the lack of fiber won't keep your hunger pangs or blood sugar spikes at bay.
