As a lifestyle medicine clinician, patients often ask me what is the ONE change they can make to improve their diet. While I always want them to eat a variety of fruits and vegetables, if there is one thing they can do, it would be to add more leafy greens into their diet. It’s no secret that greens are healthy but dark leafy greens are likely THE most nutrient dense foods on the planet. What do I mean by leafy greens? These are foods such as romaine lettuce, arugula, spinach, swiss chard, watercress, collard greens as well as, other cruciferous veggies like broccoli.
