Yes, as do all foods, but it's not very dense. There aren't very many calories either, so you'd have to eat quite a bit of romaine lettuce to get a sizeable amount of anything. There's nothing wrong with that in and of itself, but if your typical salad consists of romaine and iceberg lettuce with a smattering of tomatoes and onions, topped with cheese, croutons and dressing, you're going to be eating a "salad" with many times more calories from dressing, cheese and croutons than the vegetables themselves. For the most nutritious salad, avoid the cheese, avoid the croutons, ditch the dressing, and pile on the veggies. Put on spinach instead of lettuce for a more nutritionally dense salad.
