You've probably heard that when in doubt of what to order out, a turkey sandwich is always a safe bet, right? Well, it depends on where you're eating. Highly-processed deli meats can be high in nitrates and sodium, which is hard on the heart. Not to mention that turkey sandwiches are oftentimes loaded with full-fat mayo and include huge portions of bread (white or wheat, too much is too much). As always, check those nutritionals before you eat to know what kind of turkey sandwich you're really getting!
