The smell of food may cause bad breath

Certain foods are notorious for causing bad breath, but maybe not in the way you expect. You may think that spicy or savory foods only cause an occasional odor because the food particles remain in your mouth. While this is a common cause of bad breath, other factors may be involved. Once you eat them, ingredients from certain foods such as onions, garlic, some vegetables and spices enter your bloodstream and are transported to your lungs and affect your breath as you breathe in and out. For example, while eating garlic it is also absorbed into your bloodstream, allowing a secondary wave of aroma to make its way to your lungs, where it can exit directly through the mouth.
