Almost everyone occasionally deals with bad breath, but for some, it’s a daily struggle without an easy or fast solution. To some extent, various foods can also cause bad breath. Whether knowingly or unknowingly, consuming these foods can worsen the condition. Read further to discover which foods contribute to bad breath. Severe halitosis (and body odour) can impact while socializing and overall quality of life.
What causes bad breath in adults?
Halitosis can stem from both oral and non-oral sources, along with various other factors contributing to bad breath.
- Halitosis primarily originates from the oral cavity in about 90% of cases.
- Warm and humid conditions in the mouth, with temperatures ranging from 34-37°C and humidity levels up to 96%, provide an ideal environment for bacterial growth.
- Over 500 bacterial species inhabit the oral cavity, many of which produce odorous compounds contributing to bad breath.
- Poor oral hygiene allows bacteria, especially Gram-negative species and proteolytic obligate anaerobes, to thrive, particularly in tongue coatings and periodontal pockets.
- Inadequate oral care leads to the accumulation of food debris and plaque, causing caries and periodontal diseases like gingivitis and periodontitis, major sources of bad breath.
- Severe forms of periodontal disease, such as acute necrotizing ulcerative gingivitis and aggressive periodontitis, worsen halitosis.
- Gingival enlargement from inflammation or drugs (e.g., phenytoin) increases the risk of bad breath.
- Reduced salivary flow, due to factors like medication, salivary gland diseases, or treatments like chemotherapy, exacerbates halitosis by increasing sulfur compound concentration.
- Other contributors to halitosis include untreated carious lesions, dental restorations, and orthodontic appliances, which create areas for food and plaque retention, leading to bacterial proliferation and odorous compound production.
- About 8% of halitosis cases originate from extraoral sources such as respiratory system issues, gastrointestinal diseases, hepatic or haematological diseases, and metabolic disorders.
- Dietary products like garlic and onions, as well as certain drugs such as alcohol and tobacco, can cause bad breath.
In some cases, bad breath may be a symptom of more severe health issues, indicating the need for a thorough medical evaluation to identify and address the root cause.
What are the foods that cause bad breath?
Several foods can contribute to bad breath, primarily due to their strong odours, ability to linger in the mouth, or potential to contribute to oral bacteria growth. Here’s a list of common culprits:
1. Garlic: Contains sulphur compounds that are absorbed into the bloodstream and expelled through the lungs and pores, causing prolonged bad breath.
2. Onions: Similar to garlic, onions contain sulphur compounds that can result in persistent bad breath.
3. Spicy Foods: Spices like curry and cumin can leave strong odours that persist in the mouth.
4. Dairy Products: Milk, cheese, and yoghurt can produce an unpleasant odour as they break down in the mouth.
5. Canned Fish: Tuna and other canned fish can have strong smells that linger in the mouth.
6. Coffee: Coffee has a strong scent and can also dry out the mouth, reducing saliva flow, which helps cleanse the mouth.
7. Alcohol: Alcoholic beverages can dry out the mouth and cause bad breath.
8. Sugary Foods and Drinks: Sweets and sodas promote the growth of bacteria in the mouth, leading to bad breath.
9. Red Meat: Strands of meat can get stuck in the teeth and provide a food source for bacteria, resulting in bad breath.
10. Horseradish: This pungent root contains sulphur compounds that can cause bad breath.
11. Radishes: Another vegetable that can lead to bad breath due to its strong flavour and smell.
To combat bad breath, maintaining good oral hygiene, staying hydrated, and using breath fresheners like mint or parsley can help mitigate the effects of these foods.
