Garlic is notorious for causing bad breath. This pungent food contains sulfur compounds that enter your bloodstream and eventually reach your lungs, resulting in an unwanted garlic aroma every time you exhale.
Onions are another culprit for bad breath. Like garlic, they contain sulfur compounds that can linger in your mouth and digestive system, causing unpleasant odors.
Coffee may give you a boost of energy, but it can also give you bad breath. Coffee has a high acidity, causing dry mouth, which leads to a buildup of bacteria and an unpleasant smell.
Alcohol is known to cause bad breath due to its drying effect on the mouth. It can also lead to an overgrowth of bacteria, producing a foul odor.
Dairy products, like milk, cheese, and yogurt, contain proteins that can stick to the back of your tongue and cause unpleasant smells.
Fish, especially oily fish like salmon and tuna, can contain high sulfur compounds that cause bad breath.
Spicy foods can give you more than just a burning sensation in your mouth. The intense flavors and spices can also linger in your mouth and cause bad breath.
While citrus fruits like oranges and lemons can give you fresh breath, consuming too much can also cause bad breath.
