Eggs and meat foods trigger bad fart aka dispose of sharp wind. While grains do not increase the fart smell. Why do farts smell different?As reported from Health24, Tuesday (21/7/2009) exhaust air is a gas that comes from that source is human digestive manifold.
Can come from air that enters the body or gas produced from chemical reactions in the intestine or it could be gas produced by bacteria that live in the intestines.
Most of the gas that enters the body is oxygen gas entering through the air. By the time air reaches the large intestine, most of the left is nitrogen.
Chemical reactions between stomach acid and intestinal fluids to produce carbon dioxide, which is also a component of the air and is a product of bacterial activity. Meanwhile, the bacteria also produce hydrogen and methane.
Also what food is eaten, what is living bacteria in the gut, as well as how long people hold also determines the sharpness of the wind exhaust gases created in the body. The longer the flue the wind held, the higher the nitrogen content.
While the odor generated from this wind comes from the exhaust gas mixture of hydrogen sulfide and merkapturat, and this mixture containing sulfur.
If you eat foods containing high sulfur and sulfide produced by bacteria in the intestine also increases, this will make the smell of flatus is increasing. If food is much the elements of the fart smell will be tasteless.
The duration of the smell of exhaust air into the nose can smell other people depend on air humidity, ambient temperature, wind speed, the distance between the human and the large molecules released. However, usually the time it takes an average of 13-20 seconds.
Meanwhile, the sound coming out at the time of waste generated from wind vibration when the anus opens. The sound depends on the tightness of muscles, the speed of air travel, gas mixture and body fat.
The average human produces gas to reach 1.5 liters of gas per day. There was no difference in the frequency of wind throw between men and women, but men tend to have the exhaust sound winds greater than women.
So farting is a very natural process. Fart not disgrace, provided at the right place and time so as not to disturb others and embarrassing yourself.
