Question: What is the Nutritional Value of Iceberg and Romaine Lettuce?
Answer: Iceberg and romaine lettuce are great salad choices when it comes to calories - both have less than 10 calories per cup of fresh leaves. However, romaine lettuce is probably the better choice when it comes down to all the other nutrients.

Romaine lettuces has darker green leaves, and generally, the deeper the color, the better the nutrition. Romaine lettuce has more of a B vitamin called folate, more vitamin K, and more lutein (an antioxidant related to vitamin A).

Whenever you make a salad, choose the greens with the darkest coloring. Kale or spinach are even better than romaine or or iceberg lettuce, because the have even better nutritional value.
