Why do onions, garlic cause bad breath?

Have you ever wondered why after eating garlic or onion the breath is so strong?

However, not only onions, garlic, but also many other vegetables (kohlrabi, leeks .) also cause bad breath after you eat them. Why is that? And perhaps more importantly, is there any way to solve that mouth odor?

Some friends (especially botanical lovers) may already know that onions and garlic belong to the family of plants called Allium . As mentioned above, there are many other species in the family Allium such as palanquin, leeks, green onions, chives .

The cause of this odor comes from sulfuric substances in onions and garlic.

According to Todayifoundout, there are many causes of this odor, but mainly comes from sulfuric substances in onions and garlic. Not only that, garlic also promotes the growth of odor-causing bacteria in your mouth and thus the problem becomes worse.

You can see that even when brushing your teeth, rinsing with mouthwash and applying some other deodorant methods, your mouth is still foul (to some extent) by eating onions, garlic. The reason is that some sulfuric compounds have been metabolized and absorbed into your blood.

The main culprit of this process is identified as Allyl Methyl Sulfide , which is absorbed directly into the bloodstream during digestion. After infiltrating into the bloodstream, it will be released after some time through sweat glands and breathing through the lungs. So when you breathe out, other people will feel your breath smelling because it contains Allyl Methyl Sulfide. This is why you have cleaned your mouth but the breath still has a strong smell of garlic.

Allyl Methyl Sulfide also secretes outside the body through sweat glands.

As mentioned, in addition to breathing out of the air, Allyl Methyl Sulfide also secretes outside the body through sweat glands. And so not only breath but also your friend is very smelly after eating garlic. This effect only ceases when your body has emitted all the smelly sulfur compounds. This process can take hours, even days.

Sulfuric compounds have absorbed into the blood, so there is no effective method to immediately remove unpleasant odors after eating garlic, except how you conceal it with a stronger smell. Many people often prepare garlic dishes with parsley as this will significantly reduce the smell of garlic. Also, you can drink hot peppermint tea or milk after eating garlic, which will help you reduce the odor from your mouth significantly.
