What iceberg lettuce lacks in flavor it makes up for in crispness, versatility and storage length -- washed and stored correctly, a head of iceberg lettuce can last up to seven days in the refrigerator.
Iceberg lettuce is that plain pale green that's typically used in salads, tacos, and sandwiches. Although it's not as popular as it used to be, many people still prefer the crispness of iceberg lettuce over the darker greens. One reason it's lost popularity is due to the lack of nutritional content. Iceberg lettuce just isn't as nutritious as superfood greens such as kale, spinach, and arugula, but it's certainly not bad for you. For one thing, it's very low in calories. In fact, it has less than ten calories per cup of fresh leaves.
