Nothing says stinky breath like garlic and onions. That’s because there are roughly 33 different smelly sulfur compounds that naturally occur in garlic and onions; they linger in your mouth and are absorbed in the bloodstream and expelled when you exhale. Parsley and basil help kick garlic breath. The polyphenols (compounds that act like antioxidants) in these herbs break down the sulfur compounds in garlic. For the biggest benefit, combine garlic and either basil or parsley in the same dish (think pesto!), though it may be possible to get the garlic-breath-fighting benefits of polyphenols by eating the herbs in dishes separate from the garlic, as long as they are consumed during the same meal.
