You may have heard people comment that lettuce is just empty calories, but contrary to popular belief, this is just not true. While iceberg lettuce is not a nutritional powerhouse, other salad greens are nutritional champions.

As a general rule, the darker the lettuce leaves the more nutritious the salad. As an example, romaine and watercress have seven times as much beta-carotene, two-to-four times as much calcium and twice the amount of potassium as iceberg lettuce.
