As we all know, farting in public is a very embarrassing thing. So why do people fart? Because the intestines are always in constant peristalsis, as long as the intestinal peristalsis exists, there will be gas discharged from the anus, it will fart. So why is there gas in the digestive tract? This is because people produce more gas when they eat food due to the normal flora of the digestive tract.
These gases, along with intestinal peristalsis, move downward and are discharged from the anus. Discharge, due to the role of anal sphincter, sometimes also produce a sound. Therefore, farting is a manifestation of the normal operation of the intestine. On the contrary, if you don't fart, or fart too much, it is an abnormal phenomenon.

Fart is the waste gas emitted by the body, most of which are carbon dioxide, hydrogen and methane. In the past, it was generally recognized that the odor of farts was released by methane. In fact, methane itself doesn't stink. Modern science has proved that the 'culprit' of odor is indole, skatole, hydrogen sulfide and other odor gases.
Although fart stinks, farting is a normal physiological need, which is beneficial to people's health. It's bad for one's health that one doesn't fart all day long. People who never fart all year round are likely to have gastrointestinal problems. Drinking a cup of yogurt every day helps to change the bacteria in the gastrointestinal tract.
