Parsley: This herb has been shown to help kick garlic breath. The polyphenols (compounds that act like antioxidants) break down the smelly sulfur compounds in garlic. For the biggest benefit, combine garlic and parsley in the same dish, though it may be possible to get the garlic-breath-fighting benefits of polyphenols by eating it in dishes separate from the garlic, as long as they are consumed during the same meal.
Other food solutions: Basil, apples and spinach are also rich in polyphenols.
