- Everyone farts. Humans pass gas because bacteria in the colon break down food we can’t digest.
- It happens often. The average adult farts around 14 times per day, and up to 21 toots is still perfectly normal.
- Most gas has no smell. Ninety‑nine percent of a toot is made of odorless gases; sulfur compounds from certain foods cause the stinky one percent.
- You can’t hold it in forever. Attempting to keep it in might just make it leak out more loudly or even be reabsorbed.

Frequently Asked Questions About Farts
How many times does the average person fart per day?
The average person farts about 14 times per day, though anywhere from 5 to 21 times is considered normal. This produces about 0.5 to 2 liters of gas daily. Women and men fart at roughly equal rates, despite common misconceptions.
Why do farts smell bad?
Only about 1% of fart gas actually smells. The odor comes from sulfur compounds like hydrogen sulfide and mercaptans, produced when gut bacteria break down proteins and sulfur-rich foods like eggs, meat, and cruciferous vegetables. The other 99% consists of odorless gases like nitrogen, oxygen, carbon dioxide, hydrogen, and methane.
What foods make you fart the most?
Beans, lentils, dairy products, cruciferous vegetables (broccoli, cabbage, Brussels sprouts), whole grains, carbonated beverages, and foods high in fructose or artificial sweeteners are the top gas producers. Check out our complete guide to gassy foods for detailed information and tips.
Is it healthy to hold in farts?
While occasionally holding in gas won't harm you, regularly suppressing farts can lead to bloating, abdominal pain, and discomfort. The gas may also be reabsorbed and eventually expelled through your breath. It's healthier to let it out when you can, preferably in a socially appropriate setting.
Why do some farts make noise and others don't?
The sound depends on the gas velocity, the tightness of your anal sphincter, and the amount of gas released. Tighter muscles create higher-pitched sounds, while relaxed muscles produce lower tones. Silent farts usually involve slower gas release. Body position and clothing can also affect the acoustics.
Can you light a fart on fire?
Yes, farts can be flammable due to hydrogen and methane content, but DO NOT attempt this dangerous stunt. It can cause severe burns to sensitive areas. About 1/3 of people produce methane in their farts, making them more flammable than others.
Do animals fart?
Most mammals fart, with cows being champion gas producers (250-500 liters of methane daily). Dogs, cats, and horses all fart regularly. However, birds don't fart due to their different digestive systems, and neither do most fish (except for herring, which use farts to communicate).
What's the speed of a fart?
Farts exit the body at about 10 feet per second (7 mph or 11 km/h). The gas quickly disperses in the air, which is why the smell doesn't hit immediately. Temperature, humidity, and air circulation all affect how quickly fart smell travels and dissipates.
