What it is
Iceberg lettuce is a variety of lettuce (Lactuca sativa) grown for its crisp, mild-flavored leaves that form a dense, round head. It is one of the most widely cultivated lettuces in the United States, known for its high water content and crunchy texture.
Why it's used
Iceberg lettuce is primarily used as a fresh ingredient in salads, sandwiches, and as a garnish. Its mild flavor and firm texture make it a popular base for dishes like chef salads and taco salads, and it's also used in some pickled products for added crunch.
Health notes
Iceberg lettuce is generally recognized as safe (GRAS) by the FDA as a food ingredient. It is a source of vitamins and minerals, though in lower amounts compared to darker leafy greens. Regulatory bodies like EFSA have evaluated lettuce as a foodstuff. At typical consumption levels, it poses no known health risks.
Allergen info
Iceberg lettuce is not one of the nine FDA major allergens. It does not contain gluten.
