Guides
FartRank is a game, but the thing it measures is real biology. These guides cover what is actually known — with sources, and without pretending a leaderboard is a medical device.
How many farts a day is normal?
Between 5 and 25 for a healthy adult, around 700 mL in total. What the 1991 study measured, and why your own count is always too low.
Why do farts smell?
About 99% of it is odourless. Three trace sulphur compounds do all the damage — and the study that identified them used human judges.
Foods that cause gas
Beans, dairy, onions, sugar-free gum and cruciferous vegetables, sorted by mechanism. Volume and odour come from different foods.
Fart myths and facts
Twelve claims checked. Flammability, holding it in, whether men really do it more, and the one piece of folklore that turns out to be right.
How the game itself works
The scoring is documented in full on how scoring works — the formula, the context multiplier table, the daily limits and the rules that keep the leaderboard reasonably honest.
