"Leafy greens such as romaine lettuce, kale, collards, Swiss chard, and spinach are the most nutrient-dense of all foods. Most vegetables contain more nutrients per calorie than any other food and are rich in all necessary amino acids. For example, romaine lettuce, which gets 18 percent of its calories from fat and almost 50 percent of its calories from protein, is a rich powerhouse with hundreds of cancer-fighting phytonutrients that protect us from a variety of threatening illnesses."
