Head lettuce, often referred to as iceberg lettuce, originates from the crisphead variety of lettuce cultivated since the early 20th century in the United States. Commonly used in Western cuisine, this leaf vegetable is known for its crunchy texture and mild flavor, often featured in salads, sandwiches, and wraps. Nutritionally, head lettuce is low in calories—approximately 10 calories per cup (shredded)—and primarily made up of water (over 95%), making it a hydrating food choice. While lower in vitamins compared to other leafy greens, it still provides small amounts of vitamin A, vitamin K, and folate, as well as trace amounts of minerals like potassium and calcium.
Store whole, unwashed head lettuce in the crisper drawer of your refrigerator in a breathable bag to maintain freshness for up to one week.
Head lettuce is not a significant source of protein. It contains approximately 0.5 grams of protein per cup (about 36 grams). While it is low in protein, it still provides hydration and small amounts of other nutrients.
Yes, head lettuce is keto-friendly due to its low carbohydrate content. One cup of shredded head lettuce contains about 1.2 grams of carbs, making it a great choice for salads or wraps on a ketogenic diet.
Head lettuce is low in calories, containing just 10 calories per cup, and is a good source of hydration because it is over 95% water. It also provides small amounts of vitamin K and folate, which support bone health and cell function. However, its overall nutrient density is lower compared to darker leafy greens like spinach or kale.
A standard serving size of head lettuce is about 1 to 2 cups (shredded or chopped). This provides around 10–20 calories and is an ideal base for a salad or as a filling in sandwiches and wraps.
While both are low in calories and carbs, romaine lettuce is generally more nutrient-dense than head lettuce. Romaine provides higher levels of vitamins A and K, as well as more folate. Head lettuce, often referred to as iceberg lettuce, is milder in flavor and crispier, making it a popular choice for certain dishes like burgers and tacos.
