Salad - Salad can be healthy. It usually isn't. Lettuce is good for you, but is also fairly insignificant. It's mostly just fiber, water, and low concentrations of vitamins. Most people slather their salad in dressing, which is almost never good for you. Just because a meal has lettuce in it doesn't mean that it's good for you. 80% of the calories in any salad are probably from the dressing. The only dressing that's good for you is olive oil with a little bit of lemon juice or vinegar.
