Normally after a cup of coffee your breath tastes and smells worse, right? While that may be true, chewing coffee beans can actually go a long way in making your breath smell better for those around you. Much more effective than gum or extra-strong breath mints, roasted coffee beans inhibit the growth of bacteria that make your breath bad, which translates to better breath for you! While chewing the beans are the best, drinking coffee can actually lead to better breath as well. Just make sure you drink it black!
