What causes garlic breath and how to get rid of garlic breath
Many chefs and health-conscious people around the world love garlic. It can add a unique flavor and aroma to any meal and it is also good for the heart and is loaded with anti-oxidants. Unfortunately, the sulphuric compounds that give garlic their health benefits and taste also give people an unpleasant odor which is known as 'garlic breath'. In this article, we will cover why garlic makes your breath smell and also how to get rid of garlic breath.
Why does garlic make your breath smell
Garlic and other members of the allium plant family (onions, shallots, leeks) produce cysteine sulfoxide and this gives them their distinct odor and taste. These sulfuric compounds are very similar to the compounds that are produced by the anaerobic bacteria that cause bad breath.
There are two ways that garlic makes breath smell bad. The first way is that when you eat garlic the sulfuric compounds get in your mouth and they will immediately give you garlic breath. These odorous compounds will remain in the mouth until they are brushed, flossed, scraped, or flushed out.
The second way garlic affects your breath is through your lungs. There was an interesting study (link to the study) done in 1936 where two doctors fed garlic soup to a patient who suffered from cancer of the esophagus. Due to the cancer, the patient was fed through a tube that entered the stomach through the abdominal wall, completely bypassing the mouth. They noticed that although garlic did not enter the patients mouth, they still detected garlic in his breath 3 hours later. This old study supports other studies that have been carried out recently.
The compound that causes the breath that comes from the lungs to smell like garlic is allyl methyl sulfide (AMS). AMS is a gas which is absorbed into the blood during the metabolism of garlic. From the blood it is transferred to the lungs where it is then exhaled. Some of this AMS is even excreted from the pores of the skin. This is why garlic breath is so hard to get rid of at times. No matter how much you clean and brush your mouth, the garlic odor will still be in the air you exhale because it comes from the lungs.
How to get rid of garlic breath
The best way to get rid of garlic breath is to stop eating it, this is the only way to completely eliminate garlic breath. Also it is difficult for you to know if you have garlic breath or how bad it really is. If removing garlic from your diet is not an option here are some remedies for garlic breath. Please note that although you may neutralize the garlic breath compounds in the mouth, the sulfuric compounds will still be exhaled from your lungs, still making your breath smell like garlic. The effectiveness of these remedies are therefore debatable, but at least these will lower the smell of garlic that comes from your mouth and lowering overall the smell of garlic on your breath.
