11 Unhealthiest Foods in All of Costco Ranked

These Costco foods are loaded with calories, sodium, and sugar—enjoy in moderation.

Costco is not a health food shop, so obviously it doesn't offer just nutritious options—but there are a few items in store that should either be consumed rarely, if not avoided altogether. While it's expected that dessert or treats would be high in calories and sugar, some "healthy" options are actually anything but—for example, cauliflower crust pizza or protein bars. If you want to avoid high levels of sodium, fat, carbs, and sugar, the following list is something to keep in mind when you're shopping at the warehouse chain. Here are 11 of the unhealthiest foods you can find in Costco right now—ranked from the not-great to the number one worst.

Kirkland Signature Protein Bar

Sodium: 190 mg
Carbs: 22 g (Fiber: 10 g, Sugar: 2 g)
Protein: 21 g

The Kirkland Signature Protein Bar ($26.49) in Chocolate Chip Cookie Dough is another "health food" very high in sodium, and customers have mixed opinions about how it makes them feel. "I heat them up for 25 seconds in the microwave. They taste infinitely better," one Redditor recommended.

Otis Spunkmeyer Frozen Cookie Dough Chocolate Chunks ($20.89) are very high in calories and sugar for just a single cookie. One thing members appear to agree on is that the Otis brand is better than the Kirkland version. Again, this should be a treat.

The Pierre Signatures Angus Cheeseburger ($18.19) is very high in sodium, but the 25 g of protein takes the sting out a little. "Despite moving to a somewhat healthier diet, there's still a part of me that misses the younger days when I would eat one of these every day. It always got to me how the picture had veggies on the box though," one Redditor said.

Foster Farms Jumbo Chicken Corn Dogs ($17.29) are very high in sodium and sugar, and is a very ultra-processed food item.

I just can't do that to myself," one shopper said.
