If  the causes of bad breath  can be diverse, the main cause is for 90% of cases of oral origin1. Indeed, some foods smell strong or promote the proliferation of bacteria responsible for bad breath.

Your diet can therefore work against you if you suffer from halitosis. Among the most well-known bad breath-causing foods, garlic is certainly at the top of the list, but there are others. 

To prevent food and bad breath from going hand in hand, this article gives you tips to follow to keep your breath fresh according to your diet. 

Foods that have a high aromatic content:

In this food category, if garlic breath or onion breath are the examples that come to mind right away, the following can all be responsible for bad breath:

  • Spices and chilli
  • Cheese: especially if it is Roquefort or Camembert
  • Anchovies
  • Garlic: rich in sulfur compounds, garlic has a persistent and very characteristic odor in the mouth. 
  • Onion: Like garlic, because of its sulfur compounds, onion is often associated with stubborn bad breath. Onion breath is all the stronger when the onion is eaten raw.

Foods that dry out your mouth: 

Saliva helps eliminate bacteria present in the mouth. Foods that dry out the mouth therefore directly impact the work of saliva and lead to the proliferation of bacteria responsible for bad odors. The two most well-known foods in this category are: 

  • Coffee
  • The alcohol

Tip: It is important to drink water between meals so that saliva can do its job of eliminating bacteria, especially if you have consumed coffee or alcohol, or if you smoke.

Foods that contain sugar:

Sugar is the main culprit for the growth of bacteria in your mouth. Foods high in sugar are therefore conducive to the development of bad breath. 

  • candy and chocolate
  • Desserts and pastries
  • Sugary drinks such as soda, fruit juices or syrups

Tip: Sweet foods and snacks should be avoided between meals.

Protein-rich foods:

Like sugar, bacteria are particularly fond of proteins. Foods high in protein can therefore lead to bad smells.  

  • Red meat: if it tends to get stuck between the teeth, meat can be responsible for bad breath. 
  • Charcuterie, which is most often salty and therefore drying.

Tip: Food can get stuck between your teeth when you eat, so it’s important to floss daily to remove any food residue from your teeth.

Foods we didn’t expect to see on the list: 

They are recommended as part of a balanced diet but are unfortunately responsible for bad breath. Much like garlic, which often goes hand in hand with bad breath, these two foods also give off a strong smell:

  • cabbage and cauliflower
  • Eggs (boiled)

Of Many myths exist around bad breath , but you now know the link between bad breath and diet, what foods to avoid to limit the risk of bad breath and how to remove an onion or cabbage smell in your mouth!
