leafy greens

The raw leaves we toss into a salad may come from several varieties of lettuce: iceberg, romaine, butterhead, and loose leaf such as red or green leaf lettuce. Other salad greens used raw include spinach, kale, watercress, dandelion, radicchio and arugula. Nutrition and Health Benefits of Leafy Salad Greens Salad greens provide dietary fiber, which is beneficial in cardiovascular and gastrointestinal health. Dark leafy greens are generally more nutritious. Iceberg is known for being the least nutrient-dense salad green so it's best to mix it with other greens.
