Iceberg lettuce is a popular variety of crisp and crunchy lettuce known for its mild flavor and compact, round head of leaves. The benefit of iceberg lettuce lies in its low calorie content and high water content, making it a hydrating and refreshing addition to salads and various dishes. It also provides some vitamins and minerals, including vitamin K. While it may not be as nutrient-dense as darker leafy greens, iceberg lettuce is widely enjoyed for its texture and versatility in culinary applications.
