For a PB&J you can feel good about, go easy on the PB. It’s relatively caloric at 190 calories per tbsp., but the lunchbox favorite has 6 g of protein and hearty helping of fiber. Watch out for added salt and sugar, though. Going for the high-end brand will get you, well, a glass jar, but nutrition-wise you’re not buying much more—except a few extra calories, at 210 per tbsp.
–Verdict: Pay less and go with the brand you loved as a kid.
