What is Iceberg Lettuce?
Iceberg lettuce is a type of lettuce belonging to the Asteraceae family. It forms a round, tightly packed head with crisp and watery leaves. The vegetable gets its name from the way it was historically transported on crushed ice to keep it fresh during shipping.
Iceberg lettuce has a mild, slightly sweet flavor and a crunchy texture that makes it highly popular in salads and fast-food dishes. Unlike leafy lettuces such as romaine or red leaf lettuce, iceberg lettuce contains more water and fewer calories, making it excellent for hydration and weight management.
