Its sheer size alone can intimidate Costco regulars and newbies alike. However, whichever pool you fall in, you probably already know that the savings are worth pushing your wagon down endless aisles. But if you're health conscious about the groceries you buy for your family, sifting the wholesome products from the unhealthy food items is no easy feat at Costco.

To streamline your weekend shopping trip (so that you can spend more time Sunday Funday-ing) we've compiled the worst foods—both Costco's exclusive Kirkland brand as well as cult favorites you'll find at your local supermarket—that you should avoid at the wholesaler. From frozen party appetizers to pounds of meat that can keep in the freezer for months, find out which picks are not worth seeking coupons for.

Packaged Food Items at Costco


Inland Market Blue Crab Spread

inland market blue crab dip

2 oz: 125 calories, 8 g fat (1 g saturated fat, 0 g trans fat), 230 mg sodium, 8 g carbs (0 g fiber, N/A g sugar), 5 g protein

If you're looking to entertain and pair this blue crap dip with crunchy tortillas, seek a savory spread elsewhere. Inland's creamy dip boasts a laundry list of ingredients that include multiple sources of added sugars, as well as potassium sorbate, a potentially cancer-causing preservative, a study in Toxicology in Vitro found.


Kirkland Signature Sliced Turkey Breast

2 slices: 60 calories, 1 g fat (0 g saturated fat, 0 g trans fat), 460 mg sodium, 1 g carbs (0 g fiber, 0 g sugar), 10 g protein

While we're all for stacking sandwiches with lean protein, Kirkland's Signature Sliced Turkey Breast is probably your worst bet. Just two slices pack in a walloping 460 milligrams of heart-harming sodium. That's nearly as much salt as in 53 Rold Gold Classic Stick Pretzels!


Gabila's Potato Knishes

1 knish: 180 calories, 2.5 g fat (0 g saturated fat, 0 g trans fat), 428 mg sodium, 36 g carbs (2 g fiber, <1 g sugar), 4 g protein

The Jewish classic will take a serious toll on your waistline. One knish packs in about a fifth of your day's worth of sodium and barely any fiber to justify that carb count. Plus, will just one knish really satisfy your craving? You're bound to go back in for seconds and double snacktime's sodium intake.

Frozen Foods


Kirkland Signature Chicken Bakes

1 sandwich: 540 calories, 19 g fat (6 g saturated fat, 0 g trans fat), 1,370 mg sodium, 58 g carbs (3 g fiber, 7 g sugar), 35 g protein

At Eat This, Not That!, we're big fans of healthy frozen foods—they cut down prep time and don't require a recipe. However, these fatty chicken bakes don't fit the bill. With over half a day's worth of sodium and an ingredient list that resembles a horror novel, we suggest skipping this dish.


Cuisine Adventures Spanakopita Spinach & Feta Phyllo Triangles

cuisine adventures spanakopita

3 pieces: 200 calories, 11 g fat (3 g saturated fat, 0 g trans fat), 290 mg sodium, 20 g carbs (1 g fiber, 1 g sugar), 3 g protein

The box boasts, "Explore a world of delicious flavors," yet the backside suggests otherwise. Three small veggie-and-cheese-stuffed phyllo triangles pack in 200 calories and 11 grams of fat. Yikes!


El Monterey Chicken & Cheese Taquitos

2 taquitos: 250 calories, 13 g fat (3 g saturated fat, 0 g trans fat), 340 mg sodium, 23 g carbs (1 g fiber, 1 g sugar), 10 g protein

Taquitos are never a good idea if you're watching your waistline, and these Monterey Chicken and Cheese roll-ups are no exception.

    Mistakes Shoppers Are Making at Costco

    Here is what we've seen so you know what not to do.

Kirkland Signature Cheese Pizza

costco kirkland cheese pizza

¼ pizza: 290 calories, 12 g fat (6 g saturated fat, 0 g trans fat), 670 mg sodium, 34 g carbs (2 g fiber, 4 g sugar), 12 g protein

If you're choosing the right cheese pizza—one with low-fat cheese, no-sugar-added tomato sauce, and a garden of veggies—you can benefit from a balanced meal that crushes cravings. However, Kirkland's Signature Cheese Pizza serves up 670 milligrams of blood-pressure-spiking sodium and includes inflammatory soybean oil and added sugar in its recipe. No thanks.

Snacks & Desserts


Lorna Doone Shortbread Cookies

per 4 cookies: 140 calories, 7 g fat (1.5 g saturated fat, 0 g trans fat), 150 mg sodium, 19 g carbs (0 g fiber, 5 g sugar), 1 g protein

Soybean oil, palm oil, artificial flavor, and high fructose corn syrup are just some of the sketchy additives tossed into these shortbread cookies. A study out of the University of the Philippines Diliman even linked high fructose corn syrup to diabetes and metabolic diseases.


Keebler Sugar Wafers, Vanilla

keebler vanilla sugar wafers

4 wafers: 150 calories, 7 g fat (3 g saturated fat), 25 mg sodium, 22 g carbs (0 g fiber, 15 g sugar), 1 g protein

The first ingredient in these sugar wafers are—you guessed it—sugar! Unfortunately, the crunchy sweet treats pack in more than just the belly-busting carbohydrate. Keebler elves sneak artificial dyes into their vanilla wafers such as red #3, yellow #5, and yellow #6, which have been shown to cause ADHD in children, a study in the journal Neurotherapeutics found.

Oreo Sandwich Cookies


3 cookies: 160 calories, 7 g fat (2 g saturated fat), 135 mg sodium, 25 g carbs (0 g fiber, 14 g sugar), 1 g protein

We love a good sandwich cookie stuffed with velvety creme, but you'll want to kick milk's favorite cookie to the curb after discovering this. Aside from more than half a day's worth of sugar, Oreos contain phosphates, which may cause kidney disease, a study in Diabetes Journals found, as well as caramel color, which is deemed a human carcinogen by the Johns Hopkins Bloomberg School of Public Health. If that's the way the cookie crumbles, we definitely don't need the bulk box.


Kirkland Signature Gourmet Chocolate Chunk Cookies

costco kirkland chocolate chip cookies

1 piece: 210 calories, 11 g fat (5 g saturated fat), 125 mg sodium, 27 g carbs (1 g fiber, 16 g sugar), 2 g protein

Walking into Costco's bakery aisle is kind of like strolling into an Auntie Anne's—the wafting smell of baked goods is enough to spark cravings and discourage you from thinking twice about grabbing that pack of cookies. Unfortunately, these chocolate chip treats won't make your scale too chipper. Five grams of saturated fat and 16 grams of sugar per cookie are a low blow to your belly fat.


Kirkland Signature Butter Croissants

costco kirkland croissant

per croissant: 320 calories, 16 g fat (10 g saturated fat, 0.5 g trans fat), 36 g carbs (1 g fiber, 6 g sugar), 6 g protein

Who doesn't love a croissant, egg, and cheese? Avoid grabbing the bulk box of these buttery baked goods though, as just one crescent packs in a staggering 10 grams of saturated fat, a half-gram of trans fat, and just one gram of fiber—making for 35 grams of empty carbs.


Kirkland Signature 12" Cheesecake

costco kirkland cheesecake

1/16 cake: 420 calories, 29 g fat (18 g saturated fat, 1 g trans fat), 330 mg sodium, 34 g carbs (1 g fiber, 27 g sugar), 6 g protein

We're hoping you're not picking up this cheesecake on the reg because the 18 grams of saturated fat, one gram of trans fat, and a full day's worth of added sugar is simply unjustifiable. Save this sweet vice for a special occasion. And even then, avoiding slicing out seconds.
