Why do they smell like onions after eating them?

Some people experience an onion-like smell after eating certain foods, such as onions themselves or garlic, due to a compound called allyl methyl sulfide (AMS). AMS is a sulfur-containing compound in allium foods, including onions, garlic, shallots, and chives.

When you consume foods that contain AMS, the compound is absorbed into your bloodstream and eventually reaches your lungs. From there, it is exhaled when you breathe, resulting in a noticeable odor on your breath. In addition to breath odor, AMS can also be excreted through your pores when you sweat, leading to an onion-like smell on your skin.

AMS causes this specific smell because it contains sulfur, which has a distinct pungent odor. As the body metabolizes sulfur compounds, the characteristic smell is released.

It’s worth noting that not everyone experiences this phenomenon to the same extent. Some individuals have a higher concentration of the enzymes responsible for breaking down AMS, resulting in a less noticeable odor after consuming foods containing this compound. On the other hand, individuals with lower enzyme activity may experience a more pronounced odor.

While the smell can bother some people, it is harmless and temporary. It typically fades away as the body metabolizes and eliminates the compounds responsible for the odor. Practising good oral hygiene, such as brushing your teeth and mouthwash, can help minimize lingering breath odor.

If you find the odor particularly bothersome or persistent, you can try chewing on parsley, mint leaves, or other herbs that are known for their breath-freshening properties. These can help mask the smell temporarily.

The body’s metabolization and excretion of particular sulfur compounds cause the onion-like smell after eating foods like onions or garlic. It is a normal physiological process and should not cause concern.
