If you guessed ‘A,’ you're right! It’s not surprising that certain foods, such as garlic and onions, contribute to objectionable breath odor… but did you know it can also affect the air you exhale? Once the food is absorbed into the bloodstream, it is transferred to the lungs, where it is expelled. Brushing, flossing, and mouthwash will only mask the odor temporarily. Odors continue until the body eliminates the food.
