Worst: 7-Layer Salad
Salads are often a nutritional slam dunk, but this version is made with iceberg lettuce, which has fewer vitamins than other leafy greens. Then it’s layered with high-fat cheese and bacon. That’s all tossed with a dressing made with mayonnaise and sugar. To turn over a healthier leaf, look for salads made mostly of veggies and only a small amount of high-calorie toppings, like cheese and croutons.
