Generally, bad breath in the mouth is basically caused by two reasons: 1. poor oral hygiene; 2. gastrointestinal dysfunction. Moreover, regardless of the cause, the main culprit is bacteria. If you see a dentist, he might suggest two things: first, eat well, which means maintaining a balanced diet, consuming enough protein and carbohydrates, as well as vegetables and fruits rich in various vitamins; second, it's best to brush your teeth or use dental floss after meals. In fact, there is another method: certain foods are natural experts at removing bad breath and can prevent it from recurring.
Chinese Parsley: This herb is most effective at eliminating mouth odors, especially the smell of smoke. If you can't find Chinese parsley, cilantro or mint can also help freshen your breath. For better results, chew these for as long as possible, or use them to make tea. Additionally, these herbs are also beneficial for digestion.
Yogurt: The latest research shows that drinking yogurt daily can reduce the levels of hydrogen sulfide in the mouth, as this substance is the main cause of bad breath. Drinking yogurt regularly can also prevent the growth of harmful bacteria in the mouth that can cause gum disease or plaque. However, only natural yogurt has this effect; sugary yogurt does not.
Fiber-rich vegetables and fruits: These include apples, carrots, celery, and others. These vegetables and fruits help stimulate the secretion of saliva. Saliva not only moistens the mouth but also cleanses food particles that stick to teeth or get trapped between them. These food particles are also one of the causes of bad breath.
Foods rich in Vitamin C: Berries, citrus fruits, watermelon, and other foods high in Vitamin C create an environment in the mouth that is unfavorable for bacterial growth. Regular intake of Vitamin C is also very beneficial for gum health. However, note that Vitamin C should be obtained from natural foods, not food additives, as additives may disrupt digestive function.
