What foods can cause bad breath?

What foods give you bad breath
What foods give you bad breath?. The fact that garlic and onions cause bad breath is not new to anyone. But do you know why they cause bad breath? It’s because both garlic and onions have sulfur compounds. The bad odor of the mouth is usually caused by bacteria that release sulfur compounds when certain changes occur in their environment. In most cases, these changes are caused by food, so they are considered one of the main causes of bad breath.

Another example of this is leaving the food out of the fridge for too long, as it will rot and have an unpleasant odor. This happens because the bacteria in the food are broken down by anaerobic bacteria. The same happens inside the mouth if the proper measures are not taken.

4 foods guilty of bad breath.


In most cases, alcohol is the drying agent of choice when it comes to foods that generate bad breath. The drawback is that alcohol is used in most adult beverages, such as wine, beer or liquor. Therefore, people who drink a lot can have bad breath.

Another curious fact is that alcohol does not have a significant purpose in mouthwash. It is simply used to improve the appearance of the mouthwash, since all the chemicals to color and taste are not soluble in water and, therefore, are diluted in alcohol. For that reason, when using mouthwash, you should avoid those that contain high percentages of alcohol.

High protein foods

The main protein-rich product that you should avoid if you have bad breath are dairy products. What happens is that the body finds it difficult to break down these proteins, which causes the amino acids to accumulate in your body and turn into sulfur compounds. In some cases, this can happen if you eat chicken, meat or fish.

There are also some exceptional cases in which people can not break down grain proteins. This disease is called TMA (comes from trimethylaminuria), although it is also called “fish smell syndrome”. The name comes from the smell, which is the same as the fish that decompose. This smell has nitrogen and sulfur compounds. People with TMA should not consume foods with dense proteins, such as beans.


Bacteria can use the sugars present in food and make chains of glycans. This contributes to the creation of plaque on the teeth, which causes gum disease and tooth decay. All this increases bad breath.

Some people think that sucking a candy helps them with their bad breath, but the fact that they can not smell their own breath does not mean that other people do not suffer from the stench. In short, avoid mints, sweets and chewing gum with sugar if you want to keep your breath fresh.

Acidic foods

Coffee (both regular and decaffeinated coffee have acids)
Tomato juice
Citrus fruits (grapefruit, pineapple and orange juice)
Acidic foods are a problem because bacteria produce more sulfur in an acidic environment.

The correct nutrition is vital to eliminate the bad smell of the mouth. Now you know what foods you should avoid to reduce or eliminate bad breath.

What to eat to avoid bad breath?

Food rich in volatile sulfur compounds, such as garlic or onions or cheeses such as blue or very cured, because these compounds are absorbed into the bloodstream and then expelled by breathing.
Ketogenic diets (with high protein load and very little carbohydrate intake) that lead the body to a state of ketosis in which ketones are generated that are also released by breathing, that is, in our breathing.
Foods that reduce the secretion of saliva (leave the mouth dry), such as coffee and alcohol, which also create in our mouth an environment conducive to the proliferation of bacteria.

What foods give you bad breath

Fruits and vegetables, Mainly those that have a high content of vitamin C, such as broccoli, red peppers and citrus fruits, which create a hostile environment for the development of the bacteria that cause bad breath.
Yogurts, without sugar and preferably probiotics. According to a study conducted by a group of Japanese researchers, taking 100 grams of yogurt twice a day reduces the production of sulfur compounds. In addition, yogurt contains vitamin D that helps reduce the amount of bacteria.

Herbs and spices rich in chlorophyll, which are attributed a deodorizing effect that helps mitigate bad breath. Among the most popular herbs are parsley, basil and cilantro and between
Water, because it also stimulates the production of saliva.
Obviously, apart from all these recommendations on what to eat to avoid bad breath, we must not forget that we must maintain proper oral hygiene if we do not want to leave a bad taste in our mouths.

How to eliminate bad breath if I have gingivitis?

If we suffer from gingivitis (apart from going to our dentist), we can make mouth rinses with red salvia. We have to mix two tablespoons of red salvia with half a liter of gua, put it to boil, let it rest for twenty minutes and strain. Or prepare an infusion with a spoonful of good yerba and a cup of water, boil for ten minutes and drink after each meal. Nettle tea is also beneficial to eliminate bad breath.

Parsley is also a good remedy to kill bad breath. Boil two cups of water with several twigs and two whole teeth. Let the mixture stand and use it as a mouthwash twice a day.
