Why do people stink after eating garlic?

The smell of garlic is not only reflected in the breath, but also reaches the whole body through blood circulation, making other parts stink.

1. After eating garlic, your breath will stink.

Garlic is rich in allyl sulfur compounds, the most important of which is S- allyl alliin. This thing is tasteless when it exists alone. But garlic also contains a substance called alliinase, which is specially used to decompose alliin.

When the petals of garlic are intact and the internal tissues are not destroyed, alliin and alliinase coexist peacefully. Once garlic is cut, broken and bitten, the two will start to react and produce allicin, which is also the reason for the spicy stimulation when eating garlic raw.

Allicin and other sulfur compounds in garlic are unstable in the air. After we eat garlic raw for a period of time, it will gradually decompose into some smelly decomposition products, such as methyl diallyl sulfide and other sulfides. When these substances are mixed in the mouth, they will make our breath stink.

2. Eating garlic will make the "tail gas" worse.

After eating garlic, our "tail gas" will be particularly smelly, even with obvious garlic smell, so that listeners can instantly understand what we ate last meal.

This is also the sulfur-containing compound at work. The odor of fart is generally caused by indole, dung odor and hydrogen sulfide.

People who eat more garlic will release more sulfides, such as hydrogen sulfide, which will make the fart taste more obvious.

3. After eating garlic, defecation stinks.

Not only is it fart, but some friends even have a strange garlic smell after eating a lot of garlic, which is a normal phenomenon caused by sulfide metabolism.

If you eat a lot of protein-rich food while eating garlic, coupled with the hydrogen sulfide produced by incomplete digestion and decomposition in protein, the smell of feces is even more unbearable.
