When you pass gas, it's like Russian roulette: Will it be a light, odorless breeze or a noxious cloud that clears the room?
Why do some farts have no smell at all, while others feel like they're punching a hole in the ozone layer?
Dr. Myron Brand, a renowned American gastroenterologist, explains the science behind foul-smelling flatulence.
According to Dr. Brand, the odor of your gas largely depends on your diet.
Here's what the expert says: "A bad smell isn't a health red flag. It's simply a byproduct of what you eat and how your gut bacteria process it."
"Everyone's gut is unique. Strong odors often mean that carbohydrates aren't fully absorbed and instead ferment in your intestines."
Interestingly, it's not poor eating habits that cause the worst smells—quite the opposite. Healthier, high-fiber foods like broccoli, cabbage, and quinoa feed your gut bacteria, which produce more gas as they break down fiber.
Proteins are another culprit for particularly pungent farts, so gym-goers loading up on them may be brewing some serious stench.
Scientifically, farts aren't primarily methane but hydrogen sulfide—the gas responsible for that rotten egg smell you notice at hot springs or volcanoes.
Dr. Brand sums it up: "Some people produce methane, while others make hydrogen sulfide, depending on recent meals."
Fun fact: On average, adults fart between 10 and 20 times a day. Even Franky Vincent, the West Indies' own flatulence troubadour, sings about it!
