About Lettuce, cos or romaine, raw

Romaine — cos lettuce — is the upright, sturdy salad green with crisp ribs and a sweet, mild crunch. Far more robust than floppy butterhead or watery iceberg, it's the backbone of a Caesar salad and holds up well to a quick grilling.

Like all lettuce it's mostly water and extremely low in calories, but romaine is one of the more nutritious varieties: a good source of vitamin A (from carotenoids), vitamin K and folate, with some vitamin C and fiber. The darker, greener outer leaves carry the most.

Crisp, refreshing and nutritious for its weight, romaine is the lettuce to choose when you want a salad green that brings real crunch and a little more nutrition than the paler options.
