All lettuce, spinach, and other salad greens are low in calories. They only have about seven calories per cup. The calories in salads

typically come not from the greens but rather from dressings. Because they are high in volume and low in calories, salad greens help you to satisfy your appetite by beginning the digestive process so you tend to consume fewer calories for the remainder of your meal.

Greens also have no cholesterol and very little sodium so they are considered heart-healthy.
