Why It’s Healthy
Romaine lettuce’s dark green color, long leaves, and crunchy texture make it a very popular salad base. Two cups of romaine fulfill about 30 percent of your daily vitamin A, and nearly three-quarters of your vitamin K, per the USDA. To boost the nutritional value of your salad, mix romaine with some spinach or kale to pack in more antioxidants, or opt for a premixed blend. “Prepackaged salad green mixtures offer a wide variety of nutrients without you having to buy large quantities of each type of green,” says Kennedy. Tossing your salad greens with a small amount of healthy oil is also a great idea, as the oil adds a dose of healthy fat (and flavor) and can also improve your body’s absorption of fat-soluble vitamins from the salad, she adds.

“Romaine lettuce has a great crunch and is delicious served in a salad or on top of a sandwich,” says Kennedy. “Romaine can even be lightly grilled for a unique, slightly charred flavor.”
