Been overdoing it on the garlic and needing to rid yourself of the smell on your breath? Those of you who choose to chew on some gum or even some extra strong mints are doing it wrong as the answer apparently lies in the coffee bean. Yes, chewing on the roasted coffee beans can go some way to ridding you of your garlic or onion breath. Other good options to freshen your breath include parsley or mint leaves. If you prefer to drink your coffee rather than chew it then Israeli scientists have found that coffee can inhibit the bacteria that leads to bad breath, but best to drink it black.
