The average American still gets only ~1 serving of legumes and ~1.5 cups of dark leafy greens per week — far below what new 2025 Dietary Guidelines recommend. These 12 vegetarian superfoods are the easiest way to close that gap. They’re all grown or sold coast-to-coast, affordable, and pack more vitamins, minerals, fiber, protein, or antioxidants per calorie than almost anything else in the grocery store.
