Thanks to a seemingly endless flood of vampire novels, movies and TV shows, most of us know by now that garlic is a great way to keep Dracula at bay. Of course, garlic is a great way to keep practically anyone from invading your personal space. After all, nothing seems to stick around quite like garlic ... it can hang around on your breath for up to 72 hours, according to the Mayo Clinic.
A sulfurous compound called allicin gives garlic the power to overwhelm breath mints and chewing gum of any flavor. As allicin breaks down down in the stomach, it gives off a variety of volatile compounds that remind you of the slice of pizza you ate hours before. Those compounds make their way into your blood and work their way out through your lungs.
While garlic may not be the best food for first dates and family functions, it can work wonders for your health. Some studies have found garlic can increase blood flow and, as a result, it may lower your risk of heart disease.
