Iceberg lettuce is a crisp, pale green leafy vegetable that originated in the United States during the late 19th century. It belongs to the Lactuca sativa species and is a staple in Western cuisines, often used in salads, sandwiches, and wraps. Iceberg lettuce is loved for its crunchy texture and mild flavor. Its nutritional profile is relatively modest—it is low in calories (approximately 10 calories per 1 cup shredded) and provides small amounts of vitamin K, vitamin A, and folate. It also contains dietary fiber and has a high water content, making it hydrating and refreshing.
Store whole iceberg lettuce head in the refrigerator in a breathable produce bag to maintain crispness. Avoid washing until just before use to prevent spoilage.
Iceberg lettuce is very low in calories, containing only 10 calories per 100 grams.

It is also high in water content at about 95%, making it hydrating but not very nutrient-dense.
Yes, iceberg lettuce is highly suitable for both keto and low-carb diets as it contains only 2 grams of carbohydrates per 100 grams, most of which come from fiber. Its low carb and calorie count make it an excellent base for keto-friendly salads and wraps.
Iceberg lettuce is hydrating and provides a light source of fiber, making it good for digestion and hydration. However, it is lower in vitamins and minerals compared to darker leafy greens like spinach or kale. Additionally, it is important to wash it thoroughly to avoid potential contamination with bacteria such as E. coli.
A standard serving of iceberg lettuce is about 1 to 2 cups of shredded leaves, which weighs approximately 50 grams. This serving size provides around 5 calories and is a good portion for salads or as a topping without adding significant carbs or calories.
