What Makes Your Breath Smell So Bad


Whether you’re munching on garlic, onions or any of the many more fragrant foods, your food could cause bad breath. Your saliva helps break down food, but bacteria involved in this process can release bad odor. Other foods, like the infamous garlic, enter your blood after digestion, then travel to your lungs, causing unpleasant exhalations. Health Guidance's list of foods that cause bad breath include dairy products; garlic, onion, or other sulfuric foods and spices; acidic drinks like orange juice; dehydrating beverages like alcohol or coffee; red meat or other foods that are hard to digest; pineapple; peppers; cabbage and tomatoes.
