What is Iceberg Lettuce?
Iceberg lettuce, also known as crisphead lettuce, is a cool-weather crop that belongs to the Lactuca sativa species. Its name is derived from its resemblance to an iceberg due to its tightly packed, pale-green leaves and its ability to stay fresh during long-distance transport. This lettuce variety has become one of the most popular types of salad greens across the globe, thanks to its crisp texture and mild flavor that pairs well with various dishes.
First cultivated in the United States in the late 19th century, iceberg lettuce quickly gained popularity for its long shelf life and resistance to wilting. Its compact head makes it easy to store and transport, making it a favorite among grocers and consumers alike. Today, iceberg lettuce is grown in many parts of the world and is a staple in salads, sandwiches, and wraps.
Despite its widespread use, iceberg lettuce has often been criticized for being less nutrient-rich compared to darker leafy greens like spinach or kale. However, its unique characteristics, including its high water content and low calorie count, make it an excellent choice for those looking to stay hydrated and maintain a healthy weight.

Key Vitamins and Minerals in Iceberg Lettuce
Iceberg lettuce may not be a nutritional powerhouse, but it contains several key vitamins and minerals that support various bodily functions. Let’s take a closer look at some of the most notable nutrients found in this leafy green:
Vitamin K
Vitamin K is essential for blood clotting and bone health. A single serving of iceberg lettuce provides approximately 20% of your daily recommended intake, making it a valuable addition to a diet aimed at supporting bone density and preventing issues like osteoporosis.
Vitamin A
Iceberg lettuce is a modest source of Vitamin A, primarily in the form of beta-carotene. This vitamin is crucial for maintaining healthy vision, skin, and immune function. While darker leafy greens may offer higher levels, iceberg lettuce still contributes to your daily intake.
Folate
Folate, also known as Vitamin B9, is vital for cell division and DNA synthesis. It's particularly important for pregnant women, as it supports fetal development and reduces the risk of neural tube defects. Iceberg lettuce provides about 7% of the daily recommended intake of folate per 100 grams.
Potassium
Potassium is an essential mineral that helps regulate blood pressure, balance electrolytes, and support muscle function. While iceberg lettuce contains less potassium than bananas or sweet potatoes, it can still contribute to your overall intake when included in a balanced diet.
Calcium
Although not a significant source of calcium, iceberg lettuce does provide a small amount that contributes to bone health and muscle function. Pairing it with other calcium-rich foods can help you meet your daily requirements.
These vitamins and minerals may not be present in large quantities, but they collectively make iceberg lettuce a valuable component of a healthy diet, especially when combined with other nutrient-dense foods.
