With fun seasonal options and plenty of nutritious convenience foods lining their shelves, Trader Joe's is a healthy foodies' playground. While there are plenty of not-so-healthy choices at this neighborhood grocery store, it's easy to find healthy options, especially when it comes to snacks. Protein bars are dietitian's top picks for a healthy, filling, and satisfying snack on the go, but not all protein bars are created equal. Sure, we want the bars to be filled with protein, but nutrients like healthy fats, fiber, and ingredients included in the bars are important factors too. And while some protein bars are low in sugar, others might as well be candy bars with all the added sugar they include.

We asked dietitians to let us in on the best protein bars you can get at Trader Joe's, so you can always have a quick, healthy, and filling snack on hand. Read on, and for more on what to shop for when you don't have time to hit up your local TJ's, don't miss 10 Best Protein Bars for Weight Loss.
