The takeaway from this is to try to include more fresh or fresh-frozen vegetables in your meals. High fiber fruits like berries also pack a high-fiber punch. Fiber sucks up toxins throughout the digestive tract and is then eliminated from the body. It also helps to keep blood sugar stable, which means your energy stays stable. Yet another reason to eat real food.
