Iceberg lettuce is a type of lettuce that is commonly used in salads. It has a crisp texture and a mild, slightly sweet flavor. Iceberg lettuce is named for its appearance, as it forms a tight, compact head similar to that of an iceberg.
While iceberg lettuce is not as nutrient-dense as other types of greens, such as kale or spinach, it does contain some important vitamins and minerals. It is a good source of vitamin K, which is important for blood clotting and bone health, and vitamin A, which is essential for vision and skin health. It is also low in calories and high in water content, which can help with hydration.
