Believe it or not, bananas are one of the worst foods you can buy from Costco. But, wait a minute. Bananas are healthy, right? Right! So, what’s the problem, then? Well, according to Dr. Amy Lee, Head of Nutrition for Nucific, it isn’t the bananas that are the problem. It’s their size.

“If you actually compare one of these bananas to a normal-sized banana that you would find in a regular supermarket, you will realize it’s almost twice as big,” Lee told Eat This, Not That! And, of course, if it’s twice as big, then it has twice as many calories.

9. Protein Bars

Protein bars are often touted as healthy snacks that aid in weight loss efforts. I mean, it makes sense, after all. Protein is essential for building lean muscle and shedding those unwanted pounds. And, while these bars are packed with protein, most at Costco are also packed with sugar.

What’s worse is that some of them don’t even have much protein. Instead, they consist primarily of sugars and oils, with a little bit of protein. Scary, isn’t it? That’s why it pays to read the label before devouring any protein bar carefully.
