Dates are endlessly underutilized in American kitchens—they provide a surprising source of potassium, which is an essential actor in fluid balance in the body, working with the kidneys to turn on or off their own potassium production, thereby balancing blood pressure. Potassium can also alleviate cramping and constipation, and is essential for athletes, especially runners. Raw and unprocessed, dates are nature’s truly natural sweetener—they are actually the fruit of the palm tree. In this savory application, they serve as a nice counterbalance to the spice of the paprika and the satisfying salt of the beans. Incorporating more dates on your plate can help cravings for other unnatural sweets as well.
