The 40 Best and Worst Protein Bars

There's no denying it: protein is the name of the game when it comes to health and nutrition these days.

However, even for the most dedicated healthy eaters among us, the idea of toting around grilled chicken and egg whites everywhere we go is even less practical than it is appealing. The alternative for those who want to keep their energy levels high without reaching for the nearest convenience food, comes in the form of protein bars, the ubiquitous health food store staple that promises better health in every bite.

While the convenience of these snacks makes them enticing, what's under the wrapper varies wildly from company to company. Major brands that sit side-by-side on your favorite store's shelves can be like comparing apples and oranges, with one so-called health food relying on artificial sweeteners, high fructose corn syrup, and toxic preservatives to achieve its flavor, while another might be little more than a brick of organic fruit and nuts perfect to enjoy in place of a full meal on a busy day.

So which should you choose? After reading up on the 45 Sources of Protein You Should Be Eating — But Aren't, find out which protein-packed snacks make our list of the 40 Best and Worst Meal Replacement Bars!

Worst: With just 200 calories and 9 grams of fat, Quest's White Chocolate Raspberry Bar seems like it should be able to help you slim down, but not all of its ingredients are as healthy as you might have hoped.

MET-Rx ProteinPlus Protein Bars — Creamy Cookie Crisp

Worst: While just one of these MET-Rx bars provides you with 60 percent of your RDA of protein, at 320 calories, it's also one of the higher-calorie bars out there, and full of less-than-healthy ingredients to boot.

Myoplex Deluxe Bar — Chocolate Peanut Butter
