Do Plants Fart?

Everybody farts—and by everybody, we mean humans, cats, goats, ferrets, frogs, whales, and scores of other animals, with the notable exception of octopuses, birds, and a few other species that aren’t burdened by excess gas. But what about cacti, ferns, and other common plants? Was our garden salad once capable of letting one rip?

If you define fart as the Merriam-Webster dictionary does—to expel intestinal gas from the anus—then no, plants don’t fart, because they don’t have anuses. However, they do expel gas (including methane, a greenhouse gas found in human and animal farts), so they basically fart in their own plantlike way. According to Popular Science, microbes in trees produce gas in much the same way that microbes in the human body break down food and create gas. Methane then seeps out of a tree’s bark or stems.

Biogeochemist Patrick Megonigal, an associate director of the Smithsonian Environmental Research Center, says it isn’t known if these “farts” provide some sort of benefit to the trees. However, researchers have found “that some trees fart more than others,” Megonigal told  PopSci.

The fact that some leafy, above-ground plants release methane was only discovered in 2006. It was previously known that swamp plants release methane, which bubbles up to the surface in mud or water, but scientists didn’t realize the same rule applies to other plants and trees as well.

Some plants’ farts are more obvious than others. According to a 2016 study published in Plant Physiology, “shy plants” (officially known as Mimosa pudica plants) are less shy when it comes to their flatulence. In fact, they have been known to release a smelly stench when they’re poked or prodded. Researchers believe that gas rich in sulfur compounds is released from tiny hairlike sacs that run along the plant’s root. Six other Mimosa species are also capable of farting, and researchers say this could be a defense mechanism used to ward off other plants that encroach on their personal space. So unless you want to wade through a cloud of sulfur-infused farts, steer clear.

The Great Tryptophan Lie: Eating Turkey Does Not Make You Tired

While you’re battling your kids for the best napping spot after Thanksgiving dinner, feel free to use this as a diversion tactic: It’s a myth that eating turkey makes you tired.

It’s true that turkey contains L-Tryptophan, an amino acid involved in sleep. Your body uses it to produce a B vitamin called niacin, which generates the neurotransmitter serotonin, which yields the hormone melatonin, which helps regulate your sleeping patterns. However, plenty of other common foods contain comparable levels of tryptophan, including other poultry, meat, cheese, yogurt, fish, and eggs.

Furthermore, in order for tryptophan to produce serotonin in your brain, it first has to make it across the blood-brain barrier, which many other amino acids are also trying to do. To give tryptophan a leg up in the competition, it needs the help of carbohydrates. Registered dietitian Elizabeth Somer told WebMD that the best way to boost serotonin is to eat a small, all-carbohydrate snack a little while after you’ve eaten something that contains tryptophan, and the carbs will help ferry the tryptophan from your bloodstream to your brain.

But Thanksgiving isn’t exactly about eating small, well-timed snacks. It’s more about heaps of mashed potatoes, mountains of stuffing, and generous globs of gravy—and that, along with alcohol, is more likely the reason you collapse into a spectacular food coma after your meal. Overeating (especially of foods high in fat) means your body has to work extra hard to digest everything. To get the job done, it redirects blood to the digestive system, leaving little energy for anything else. And since alcohol is a central nervous system depressant, it also slows down your brain and other organs.

In short, you can still hold turkey responsible for your Thanksgiving exhaustion, but you should make sure it knows it can share the blame with the mac and cheese, spiked apple cider, and that second piece of pumpkin pie.
