Answer: Superfoods are foods that contain a variety of nutrients, such as antioxidants, which are thought to ward off cancer. They also have healthy fats, thought to prevent heart disease; fiber, thought to prevent diabetes and digestive problems; and phytochemicals — the chemicals in plants responsible for deep colors and smells, which can have numerous health benefits. Superfoods support neural networks, optimize day-to-day brain functioning, enhance moods, sharpen mental focus, and more.
