10 Quick Ways Get Rid of Onion Breath

As healthy and as yummy as onions are, they certainly don’t smell good. And once you eat some onions, getting rid of the smell can be pretty difficult. Luckily, there are a couple of ways you can eat onions and still have a fresh breath. Here are 10 quick, natural, and effective ways to get rid of onion breath.


What Causes Onion Breath?

Onions contain sulfur compounds. These chemicals are responsible for the distinctive taste and smell of onions. However, there are two ways onions can give you onion breath. 

Onion breath in your mouth happens when you chew the onion. The sulphuric compounds mix with the bacteria in your mouth. That’s why you can smell the onion in your breath after eating. 

But why is onion breath still an issue even after you’ve already eaten? When you’re digesting onions, the sulphuric compounds also get absorbed into your bloodstream. They find their way to the lungs which then releases a foul odor every time you exhale.

2. Lemons Work Against Onion Breath

Rinse your mouth with lemon water two to three times a day. A tablespoon of lemon juice in a cup of water can help neutralize onion breath. The citric acid in the lemon contains antibacterial properties that can kill bacteria that cause bad breath.

Other Foods That Cause Bad Breath

While onion breath is certainly not pleasant, there are a couple of other healthy foods that cause bad breath too. Watch out for these in your diet before an important event:

  • Garlic: The garlic odor can be very strong. The best way to get rid of it is by utilizing plant chemicals like chlorophyll and polyphenols to bind to sulfur compounds in garlic. Eat herbs like parsley, basil, thyme, cilantro, mint, or dill to get rid of garlic breath.
  • Strong cheeses: There’s nothing classier than a nicely arranged cheese board. But, the smell of cheeses like Stilton, Roquefort, or Camembert can linger in your breath. Eating vegetables, using mouthwash, or gargling with saltwater are the best ways to get rid of cheese breath.
  • Horseradish: This member of the mustard family is a great source of dietary fiber, vitamin C, folate, potassium, calcium, magnesium, zinc, and manganese. Despite its benefits, cut or chewed horseradish releases mustard oil, which comes with a really bad smell. Gargle with saltwater or use mouthwash to get rid of it quickly.
  • Kombucha: This fermented drink is a popular superfood with a lot of amazing benefits. But, this vinegary drink doesn’t smell good at all. Drinking some green tea or chewing herbs will eliminate the bad breath caused by kombucha.

Could Your Bad Breath Be a Dental Issue?
