Why Do Farts Smell?

Many people wonder why some farts smell significantly worse than others. The noxious odor associated with farts is created when gases combine in the large intestine. Miniscule amounts of methane, carbon dioxide and hydrogen combine with ammonia and sulfur to create this unpleasant odor.

Farts created by foods with a high sulfur content generally smell worse than others. Sulfur creates the rotten egg smell many associate with a particularly unpleasant fart. These foods include cruciferous vegetables, onion, garlic, dairy products, red meat and plant-based proteins.
