The classic peanut butter and jelly sandwich has been a lunchbox staple for years. This popular sandwich is actually a good meal choice in moderation. According to Marilyn Tanner-Blasiar, registered dietitian with Washington University School of Medicine in St. Louis and American Dietetic Association spokesperson, peanut butter is filled with protein, which helps to fill kids up, and monounsaturated fats, a healthier form of fat. Elisa Zied, registered dietitian, author of "Feed Your Family Right!" and American Dietetic Association spokesperson, recommends going with natural peanut butter or reduced-fat peanut butter for a healthier sandwich and whole-wheat bread to add some fiber.
For the sweetness factor, add jelly. Just keep it to 100 percent fruit spread for a healthier twist [source: Krieger].
