Worst: Bologna
Bologna and mustard is a lunchbox classic, but it isn’t the healthiest option. Made from a mix of cured beef and pork, bologna is loaded with fat. It packs in 8 times the fat — and 4 times the calories — of regular deli ham. A 3-ounce serving also delivers more than 40% of all the sodium you should get in a day. For a leaner sandwich, go with low-sodium chicken, turkey, ham, or roast beef.
