Why Do Some People's Fart Smell More Than Others?

Farts are physiological outcomes but are caused by bacteria in the colon, these bacteria produce hydrogen and methane. The stink however comes when these bacteria are fed with sulphur-rich foods. It only constitutes 1% of the gas but does raise a stink. Remove foods high on sulphur from your diet like cabbage and cheese and replace them with fish and avocados.

Even though farting is one of the most natural physiological outcomes, farts can be really embarrassing for producer and consumers alike. A lot of us try really hard to control ourselves from exploding during the day fearing social isolation and being a butt of jokes (literally!!). What we all realize though is that when alone the joy of letting go is satisfying to the core.

Farts are byproducts of a lot of factors including air we swallow, chemical reactions on food in the GI tract, gas expelled by bacteria in the colon, and gases absorbed from blood by the colon. Out of all gases oxygen (completely absorbed by the body), carbon dioxide (generated from digestion process) and nitrogen (the least absorbed by the body), do not produce any smell.

Bacteria in the large intestine produce hydrogen and methane but their amounts are negligible and almost absent in most people. The reason why farts stink bad is due to increase in sulfur-containing compounds like hydrogen sulfide and mercaptans produced by gut bacteria when your diet is loaded with sulfur-rich food like broccoli, brussels sprouts, cauliflower, bok choy, meat (beef/pork), eggs, cheese, whole cow’s milk, garlic, onions, horseradish, and sulfite preserved foods like wine and dried fruits. Even though sulfur constitutes 1% of the gas, it is enough to raise a stink.

Eliminate high sulfite foods from your diet and substitute them with their low sulfur counterparts such as fish, chicken, ginger, chili peppers, avocados, eggplant, spinach, and carrots. The more time gas stays in your gut the more the bacterial action on it, making any food produce stinkers. So keep your bowels active and moving by maximizing intake of fresh fruits, veggies and fiber rich foods, and hydrate with lots of water. Till then, practice the straight-faced “It wasn’t me” expression.
