Is Iceberg Lettuce Nutritionally Worthless?

There are many who say the popular, crunchy iceberg lettuce is so devoid of nutrition it is not worth eating. Yet a quick look at a food composition table reveals this variety has dietary fiber, lots of water as well as vitamin K, folate, and beta-carotene. However, bibb lettuce has 6 times the beta-carotene, and romaine provides more than half the recommended daily vitamin K.

PositiveTip: Don't sneer at iceberg lettuce. Include the many other types of lettuce in your diet, also!
