  • You may have laughed at the idea of 'Silent But Deadly' farts. But is this faint flatulence

  • really more potent than the boisterous wind you let loose? Are silent farts worse?

  • It may surprise you to find out that a large portion of farts are the result of swallowed

  • air. Whether from chewing a lot of gum, drinking pop, or simply from eating food, excess air

  • enters your body and has to go somewhere. And while some is released through burping,

  • the rest ends up in the digestive system and eventually comes out your other end. But when

  • expelled, this gas is made of mostly nitrogen, hydrogen and carbon dioxide -- all of which

  • are odourless. Which explains why some farts are obnoxiously loud, but contain little to

  • no smell.

  • The second half of the equation is gas from the large intestine. After travelling through

  • 25 feet of small intestine, the indigestible portions of food make their way to the colon.

  • Here, millions of bacteria feast on the remaining food, and ferment it. And this is where things

  • can get...stinky! Though the bacteria do release some useful vitamins, they also produce chemicals

  • containing sulfur, which is responsible for the smell in flatulence. Add to that a sulfur

  • rich diet with things like eggs, meat or broccoli, and you're likely to produce some interesting

  • odours. The longer these foods stay in the gut, the more they ferment and smell. Still,

  • this smelly portion accounts for around only 1% of most farts.

  • In the absence of the other odourless gases, however, these farts are concentrated with

  • smell and generally quiet because there is less volume. Silent, but deadly! Having said

  • that, loud gas can be just as smelly as the quiet ones, if the sulfur components are there.

  • Simply put, your loud farts likely contain a higher proportion airborne, odourless gases,

  • whereas the quieter flatulence tends to have a higher proportion of the smell.
