Less sugar

Not only artificial flavors but also artificial sugars harm the body, if eaten in excess. People who wish to consume lettuce in good amounts need not bother about this as it has less sugar content. Iceberg lettuce is preferred over most other types of lettuce due to its moist crispiness. While its true that most darker greens are richer in nutrients, iceberg lettuce is still a very healthy choice. Low in saturated fat and cholesterol (practically none) its a good source of iron, vitamin B6, K, A, and C.
