Farting is a normal physiological phenomenon. When people eat food, they produce more gas due to the normal flora of the digestive tract. These gases run downward with intestinal peristalsis and are discharged from the anus. During discharge, due to the function of anal sphincter, sometimes there is a sound. Therefore, farting is a manifestation of the normal operation of the intestine. On the contrary, if you do not fart, or fart too much and smelly, it is an abnormal phenomenon.
Why fart
Fart occurs because some of the food we eat has not been decomposed. The undigested part, including fiber and sugar, becomes the food of coliform bacteria. E. coli will exhaust after a full meal. These gases accumulate in the body, causing a surge of air pressure. When the pressure is too high, it will be pushed out of the body and form a fart.
How much fart is related to people's diet
Some people like to eat onions, ginger, raw garlic, potatoes, sweets, beans and pasta. Because these foods contain a matrix that can produce a large amount of hydrogen, carbon dioxide, hydrogen sulfide and other gases, they tend to increase waste gas and fart continuously after eating. The amount of fart is also related to the strength of human digestive function. In case of indigestion, intestinal bacteria ferment quickly, which is easy to produce gas and make people fart. A scientist found that a person farts about 14 times a day. Every day, everyone releases about 500 ml of waste gas. 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. People who never fart all year round are most likely to have gastrointestinal problems.
