The Extensive Gas Production Caused by Consuming Beans: A Scientific Explanation
When your tum-tum starts rumbling post-bean feast, you're bound to question, "Why am I farting so much after eating these little legumes?" And guess what? You're not alone. Tons of folks out there are pondering the same thing, given the flatulent reputation of beans. So, we asked a posse of dietitians, "Does beans' gas-making prowess live up to the hype?" Their answer? A resounding 'yes.'
But don't start sifting through your pantry just yet. Beans have some awesome perks, like being fiber-rich and protein-packed, making them a staple in everything from dal to hummus. So, before you boycott the bean kingdom, read on to discover the deal behind their gas-inducing powers and how to manage your bumblings, er, blessings.
So, what makes beans such a gas factory?
Remember when we said beans are chock-full of fiber? Well, one specific type of fiber is the culprit in this case: oligosaccharides. These sugars are also lurking in lentils, peas, certain grains, fruits, and veggies. The problem is that our gut can't easily break these down, so they journey on to our large intestine where bacteria chow down on them (fermentation), leading to the production of gas. To spell it out, that fermentation happening in your large intestine is the root cause of your bean-induced digestive distress, aka stomach pain, cramping, bloating, and, of course, farting.
Do all types of beans cause gas?
Since legumes are high in oligosaccharides, it's safe to assume they can trigger gas across the board. Classic favorites like chickpeas, black beans, and kidney beans are guilty as charged.
On the flip side, the fiber content in beans isn't consistent, so fewer oligosaccharides equal less gas, theoretically. So beans and other legumes on the lower side of the fiber spectrum are generally safer to devour. Some folks claim that lentils are easier to tolerate, whereas options like adzuki beans, mung beans, black-eyed peas, pigeon peas, or split peas tend to be kinder to your GI system. Conversely, "kidney beans are really high in fiber," so expect more gas from them.
Is it inevitable to fart after eating beans?
Not necessarily. Everybody (and every body) is unique, so how you respond to a particular dietary trigger can vary greatly. If you've got a pre-existing digestive condition like IBS, you might have a lower tolerance. Likewise, people who eat a diet low in fiber might struggle to digest a meal that's heavy in beans simply because it's a shock to the system, but folks who already eat a high-fiber diet will probably fare better.
How can I stop farting after eating beans?
Glad you asked! You have plenty of options for preventing or taming bean gas, ranging from supplements to dietary changes to cooking tweaks.
- Soak 'n Rinse: If you're working with dried beans, try soaking them overnight in water to draw out some of the oligosaccharides. Just remember not to reuse the water while cooking, as the beans could then reabsorb the oligosaccharides and defeat the purpose.
- Canned Care: Generally, canned beans tend to be more tolerable because some of those oligosaccharides leach out during the canning process. Even still, rinsing them well before cooking or consuming them can help.
- Over-the-Counter Enzymes: You can purchase digestive enzyme supplements like Beano to help your stomach cope. They work by providing the missing enzyme your body needs to break down oligosaccharides before they reach the large intestine, thus preventing them from reaching the bacteria in your large intestine.
- Low-FODMAP Diet: If meals are continually causing issues, consider trying a low-FODMAP diet. This temporary dietary change involves cutting out fermentable carbohydrates like oligosaccharides that may irritate the small intestine. The goal is to help you pinpoint the specific foods causing problems, but remember to do this under the guidance of a registered dietitian rather than going it alone.
- Gradual Fiber Intake: Increase your fiber intake slowly rather than drastically, increasing your tolerance to those gas-producing oligosaccharides.
Finally, if all else fails and you're left waiting it out, find a comfortable spot, apply warm compresses, drink cooling beverages like mint tea, and don't hesitate to let one rip if necessary. And remember, there's nothing sweeter than a well-deserved relief!

- The gas-inducing powers of beans are mainly due to the high amount of a specific type of fiber called oligosaccharides, which are not easily broken down in our gut and lead to fermentation in the large intestine, causing gas, bloating, and farting.
- While all types of beans can cause gas due to the high levels of oligosaccharides, the fiber content in some beans is lower, making them generally safer to consume, such as lentils, adzuki beans, mung beans, black-eyed peas, pigeon peas, and split peas.
- Not everyone responds the same way to eating beans, as individual reactions to dietary triggers can vary greatly, depending on factors like pre-existing digestive conditions and current fiber intake.
- To help prevent or manage bean gas, various options are available, including soaking dried beans overnight, rinsing canned beans, taking digestive enzyme supplements like Beano, following a low-FODMAP diet, and gradually increasing fiber intake.
- In addition to workouts and food, health-and-wellness topics can include understanding the digestive effects of foods like beans, as well as relationship advice and general wellness tips.
- While it may be uncomfortable, leaving it out and applying warm compresses, drinking cooling beverages like mint tea, and releasing gas when necessary can provide some relief after consuming beans.
