The Nutritional Showdown: Lettuce vs. Cabbage
While often mistaken for one another, lettuce and cabbage are from different plant families with distinct nutritional profiles. Cabbage is a cruciferous vegetable, while lettuce is a leafy green. Both are healthy additions to a diet, but their nutrient density varies.
Cabbage generally has a stronger nutritional profile than iceberg lettuce, with higher amounts of vitamins C and K, and more fiber. However, darker lettuces like romaine and red leaf can offer more vitamin A and folate.

Health Benefits: A Closer Look at Each Leafy Green
Benefits of Cabbage
Cabbage is rich in nutrients and antioxidants. It contains polyphenols and sulfur compounds that help reduce inflammation. It is high in Vitamin C, supporting immune function and skin health, and a good source of Vitamin K1 for blood clotting and bone health. Cabbage's fiber aids digestion and supports gut bacteria. Fermented cabbage provides probiotics. Anthocyanins in red cabbage may reduce heart disease risk.
Benefits of Lettuce
Lettuce, especially darker varieties, offers health benefits, particularly hydration. It's over 95% water. Romaine lettuce is rich in beta-carotene (converted to Vitamin A) for eye health and immunity, and folate for cell growth. Raw vegetables, including lettuce, may improve mood. Lettuce also provides vitamin K for bone health.
Culinary Uses and Practicality
Lettuce is typically used raw in salads and sandwiches. Cabbage is more versatile, used raw in coleslaw or cooked in stir-fries, soups, and stews. Cabbage also lasts longer and can be fermented. Both aid weight management as low-calorie, high-fiber foods. Cabbage's higher fiber may be more satiating. Lettuce is better for hydration, while fermented cabbage is superior for gut health.
Conclusion: Which Leafy Green Wins?
The choice between lettuce and cabbage depends on your nutritional goals. Cabbage generally offers more vitamin C, vitamin K, fiber, and antioxidants. Darker lettuces excel in vitamin A and folate. Iceberg lettuce is the least nutrient-dense but still hydrating. Including a variety of both is the best approach for a broad range of nutrients.
