Romaine lettuce, also known as cos lettuce, is the most nutritious of all lettuces and is an excellent source of Vitamin C - more than five times that of iceberg lettuce.

This salad vegetable has deep green, long leaves with a crisp texture and a stronger flavor than iceberg lettuce, and is more tender and sweeter than other lettuce varieties. Like all lettuces, it has a low-calorie content and high water volume.

In addition to its high Vitamin C content, romaine lettuce is also an excellent source of Vitamin A. Research has shown that to absorb maximum Vitamin A from this salad leaf, it should be combined with a fat, such as olive oil from salad dressing.

Romaine lettuce is also a rich source of folic acid, and contains phosphorus, potassium and fiber. Phytochemically, this form of lettuce is a good source of lutein and zeaxanthin - these phytochemicals are important antioxidants that battle many diseases. Romaine lettuce also contains a significant amount of lactucaxanthin, which is a rare dietary carotenoid that was found to suppress the Epstein-Barr virus, one of the most common viruses in humans.

Health Benefits

Macular Degeneration

Romaine lettuce is rich in lutein and zeaxanthin, which are carotenoids found naturally in the eye that fight age-related macular degeneration, the leading cause of irreversible vision loss in the elderly.

Weight Maintenance

In a study conducted in the US, it was found that starting off a meal with a low-calorie salad gave a sense of fullness and reduce subsequent calorie intake, which may be an effective way for managing weight.

Reduced Inflammation

Salicylic acid, a main compound found in aspirin, which is used to treat inflammation, has been found in romaine lettuce. Salicylic acid is a cyclooxygenase-2 (COX-2) inhibitor, a key enzyme involved in inflammation, certain cancers, and the promotion of heart disease.

Tips for Using Lettuce

  • Look for lettuce with large, darker-green, unwilted outer leaves, as the darker the leaves, the more nutrients they contain.

  • Store lettuce and other salad vegetables in the refrigerator, where they should keep for up to ten days.
