Coffee use has come to represent companionship and socialization. Date pits and seeds are typically thrown away as useless stuff. Therefore, the main goal of this effort is to replace the existing coffee powder with a new coffee powder made from date seeds to prevent the negative effects of consuming a lot of caffeine from coffee. This concept may also present small and medium-sized businesses with new entrepreneurial challenges in the beverage industry. The results clarified that there were significant differences among the roasted whole-date seeds, barley grains powder, 75% roasted whole-date seeds+ 25% roasted barley grains powder, 50% roasted whole-date seeds+ 25% roasted barley grains powder, and light commercial Brazilian coffee powder in terms of physiochemical parameters, such as moisture, protein, lipids, total carbohydrates, and ash contents, as well as mineral composition, such as Ca, Mg, K, Na, P, and Fe, and phytochemical compounds, such as total phenols, total carotenoids, total anthocyanin, and tannins.  As a complete replacement for regular coffee, the study suggests using coffee powder made from roasted whole-date seeds powder. This will prevent the negative effects of consuming too much caffeine, save 2.10 billion pounds (or the equivalent amount of money), and reduce and recycle waste through value-adding applications. A lack of healthful use of date pits results in both financial and nutritional loss because they are an abundant source of phenolics, antioxidants, and dietary fiber.
