Know how your eating habits might be the cause of bad breath

Our eating habits can be the cause of our bad breath. Yes, you read it right, one can never think that the food that we eat, and our eating habits are the reason behind bad breath. However, today we will learn about the eating habits-related causes and effective solutions for bad breath. But before that, let us understand a little about bad breath also known as Halitosis in medical terms. Bad breath/Halitosis typically originates in the mouth, where bacteria break down food particles, producing volatile sulphur compounds (VSCs) that have a foul odour. However, systemic conditions, medications, and dietary habits can also contribute to the problem. It is a common condition that can affect anyone at any age. It's often a source of embarrassment and social discomfort. While there are several causes of bad breath, one significant factor is often overlooked: our eating habits.

Certain foods are notorious for causing bad breath. These foods contain compounds that can cause unpleasant odours, either directly or through metabolic processes.

• Sugary Foods and Drinks: Sugary foods and beverages can exacerbate bad breath by providing a breeding ground for bacteria. These bacteria feed on sugar and produce acids and VSCs as by-products, contributing to bad breath [2].

• Sulphur-Containing Foods: Garlic and onions are two prime examples of foods that can cause bad breath. These foods contain sulphur compounds that, when metabolized, produce strong-smelling molecules. These molecules enter the bloodstream and are expelled through the lungs, leading to persistent bad breath. [2]

• High-Protein Foods: Diets high in protein, such as those emphasizing meat, eggs, and dairy products, can also contribute to bad breath. When protein is digested, it produces ammonia and other by products that can cause an unpleasant odour. [2]

    Apart from these foods, our unhealthy eating habits also add to the bad breath in the mouth. While certain eating habits can influence the freshness of your breath, here are some habits to be mindful of:

    Unhealthy eating habits which cause bad breath:

    ➣ Skipping meals, particularly breakfast, can lead to bad breath. Eating stimulates saliva production, which helps cleanse the mouth by washing away food particles and bacteria. Without regular meals, saliva flow decreases, leading to dry mouth and increased bacteria.

    ➣ Consuming food late at night, especially before bed, can contribute to bad breath. During sleep, saliva production decreases, which means food particles remain in the mouth longer, providing a feast for bacteria. Additionally, late-night eating can increase the risk of gastroesophageal reflux disease (GERD), which can also cause bad breath.

     

    How to get rid of mouth Odour?

    There are various ways for preventing bad breath. Just as some foods can cause bad breath, others can help combat it. Incorporating these foods into your diet can help maintain fresher breath.

    • Fibre-Rich Fruits and Vegetables: High-fibre fruits and vegetables such as apples, guava, and vegetables like carrots help keep your mouth clean by increasing saliva production. Saliva is essential for neutralizing acids and washing away food particles and bacteria. [2]

      • Probiotic Foods: Probiotic-rich foods like yogurt, kefir, and fermented vegetables can help balance the bacteria in your mouth and digestive system, reducing the presence of odour-causing bacteria. Consuming probiotics reduced the severity of halitosis. [3]

      • Green Tea: Green tea contains polyphenols, which are natural antioxidants that can reduce bacterial growth and neutralize sulphur compounds. Green tea polyphenols effectively reduce bad breath by inhibiting the growth of bacteria that produce foul-smelling compounds. [4]

       

      Role of Water in Preventing Bad Breath

      Staying hydrated is crucial for maintaining fresh breath. Water helps rinse away food particles and bacteria, and stimulates saliva production. Saliva is the mouth’s natural defence against bad breath, as it neutralizes acids and washes away debris. Dehydration can lead to dry mouth, or xerostomia, which is a significant cause of bad breath. Without adequate saliva, bacteria can thrive, leading to an increase in VSCs. One has to maintain good hydration to lower the levels of VSCs in one breath.

      Oral Health and Hygiene Practices to Complement Dietary Changes [5]

      While diet plays a crucial role in maintaining fresh breath, it must be combined with good oral hygiene practices to be effective.

      • Brushing and Flossing: Regular brushing and flossing are essential for removing food particles and plaque from teeth and gums. Without proper oral hygiene, food particles can remain in the mouth, promoting bacterial growth and bad breath. You have to brush twice a day and floss once a day to maintain oral health and prevent halitosis.

      • Tongue Cleaning: The tongue can harbour bacteria and food particles, contributing to bad breath. Using a tongue scraper or brushing your tongue can significantly reduce bacteria and improve breath quality. Tongue cleaning reduces bad more effectively than brushing alone.
      • Use of Mouthwash: The use of antiseptic mouthwash containing essential oils and chemical compounds can directly oxidize VSCs to non-malodorous products and is capable of killing odour-causing microorganisms, thereby reducing bad breath. [2]

      Tips for Managing Bad Breath Through Diet

      To manage bad breath effectively, consider the following practical dietary tips:

      ✔ Ensure your diet includes a balance of proteins, carbohydrates, and fats, and avoid excessive consumption of any one food group. Include more fibres from fruits and vegetables.
      ✔ Avoid skipping meals to maintain steady saliva production.
      ✔ Reduce the intake of sugary foods and beverages to limit the growth of odour-causing bacteria.
      ✔ Drink plenty of water throughout the day to keep your mouth moist and rinse away food particles.
      ✔ Sugar-free chewing gums stimulate saliva and thus increases salivary buffers and enhances washout of sugars.
      ✔ Incorporate high-fibre fruits and vegetables into your diet to help clean your mouth naturally.
      ✔ Add probiotic-rich foods to your diet to promote a healthy balance of oral and gut bacteria.
      ✔ Drink green tea to benefit from its antibacterial properties and freshen your breath.

        Bad breath can be a distressing condition, but understanding how eating habits contribute to it can help you take control. By being mindful of the foods, you consume and adopting healthier eating habits, you can significantly reduce the likelihood of bad breath. Incorporating foods that promote fresh breath, staying hydrated, and maintaining good oral hygiene are all essential steps toward achieving and maintaining fresh breath. Remember, a balanced diet not only contributes to overall health but also plays a crucial role in oral hygiene and breath freshness.
