Understanding the Calorie Count of Assorted Lettuce
Assorted lettuce, often sold as a pre-packaged mix of various greens, provides a healthy, low-calorie foundation for countless meals. The exact calorie count for 100g of assorted lettuce can vary slightly depending on the specific varieties included in the mix, such as romaine, iceberg, red leaf, or butterhead. On average, you can expect a 100g portion of mixed greens to contain between 13 and 17 calories, making it an excellent choice for weight management. This minimal caloric contribution, combined with high water content, means you can consume a substantial volume of greens to feel full without significantly impacting your daily calorie total.
Nutritional Breakdown of Common Lettuce Varieties
To appreciate the full nutritional picture, it's helpful to look at the individual components of a typical assorted lettuce mix. The different varieties offer distinct nutritional profiles and textures.
- Romaine Lettuce: With approximately 17 calories per 100g, romaine is one of the more nutrient-dense options. It is notably high in vitamins A and K, as well as folate, and offers a satisfying crunch.
- Iceberg Lettuce: The lightest in terms of both color and nutritional density, iceberg contains around 14 calories per 100g. While it provides exceptional crispness and hydration, it has lower vitamin and mineral content compared to its darker counterparts.
- Butterhead Lettuce: Known for its tender, buttery texture, butterhead contains approximately 13 calories per 100g. It is a good source of vitamin A and folate.
- Red Leaf Lettuce: This vibrant, colorful lettuce contains about 16 calories per 100g and is particularly rich in antioxidants called anthocyanins, which give it its deep red color.
- Green Leaf Lettuce: A staple in many mixes, green leaf lettuce offers around 15 calories per 100g and is a reliable source of vitamins A and K.
The Importance of Color and Variety
The calorie difference between lettuce types is minimal, but the nutritional disparity is more significant. A general rule of thumb is that the darker the green or red of the leaf, the more nutrient-dense it is. For instance, a 100g portion of romaine has substantially more vitamin A than the same amount of iceberg. By choosing an assorted mix, you benefit from a wider range of vitamins, minerals, and phytochemicals that different lettuce types offer.
Beyond Calories: Other Health Benefits
While the low calorie count is a major draw, assorted lettuce provides numerous other health benefits:
- Excellent Hydration: Composed of over 95% water, lettuce contributes to your daily fluid intake.
- Vitamin Powerhouse: It is a valuable source of essential vitamins, including vitamin K for bone health and blood clotting, and vitamin A for vision and immune function.
- Boosts Gut Health: The dietary fiber in lettuce aids digestion and can contribute to a feeling of fullness.
- Rich in Antioxidants: Darker leaf varieties, especially red ones, are rich in antioxidants that protect the body from cell damage.

| Assorted Mix | ~13-17 | Variable | Combines flavors and nutrients from different types |
How to Prepare and Store Assorted Lettuce
To get the most out of your assorted lettuce mix, proper preparation is key. Always rinse the leaves in very cold water right before serving. To revive limp leaves, a few minutes in ice water can work wonders. Dry the leaves thoroughly before dressing, as excess water will cause dressing to slide off. Tearing the leaves instead of cutting them can help preserve vitamin C content and prevent discoloration. For optimal nutritional value, it's best to consume lettuce while it is fresh and crisp, as it doesn't preserve well through canning or freezing. To extend shelf life, wrap washed, dry leaves in paper towels and store in a plastic bag in the refrigerator's produce drawer.
Conclusion
In summary, the number of calories in 100g of assorted lettuce is extremely low, generally falling in the 13-17 calorie range. The specific mix of greens will influence the final calorie count and, more importantly, the nutritional profile. Choosing darker varieties like romaine and red leaf offers a richer source of vitamins, minerals, and antioxidants compared to lighter options like iceberg. By opting for a mix, you gain a variety of textures and flavors while maximizing your nutritional intake for minimal caloric cost. This makes assorted lettuce a highly recommended component of any healthy, balanced diet.
