Reminds me of the cure for lactose intolerance: You just have to keep drinking milk until your microbiomes adapts.

That seems like a very shitty cure.. But on a more serious note, does that actually work, even if just a bit?

Maybe? What follows is just my own dumb anecdotes.

For a long time, I sometimes had issues. I'd keep anti-diarrhea pills in stock at home. I kept some in the car. I even had some in blister packs my wallet (they'd get smashed up over time, but they still worked in powdered form and the desperation was very real).

I didn't know why that was a problem, but I definitely knew it was a real problem and that it could erupt at any time, so I treated the symptoms when that was useful to me. Sometimes, those shitty days on the toilet were intense. They'd wreck me, physically and mentally, for far longer than I want to think about.

Eventually, after decades, I noticed a pattern: Milk. Days when I drank milk or ate ice cream were much more likely to be problematic than days when I did not.

But then, I noticed that some other milk products like cheese were usually just fine. And that made sense and fit the pattern well, because the fermentation of cheesemaking reduces lactose very significantly.

And I like milk. So, experimentally, I started buying lactose-free milk. This worked well, but it was expensive and it tastes different. That helped to further define the pattern.

I started buying cheap lactase tablets instead, in bulk. That saved a fair bit of money, tasted good, and it also worked fine. This also reinforced the observed pattern.

Somewhere along the line, I became interested in kefir, so I bought some completely non-mystical mass-produced kefir from the grocery store and drank some.

Kefir treated me fine (yay fermentation). I found that adding a bit of kefir to a glass of milk also worked: That was never problematic at all, even without lactase tablets. (And it let me stretch that delicious, to me, kefir flavor out over a larger volume -- which also saved some money.)

I found that these observations strongly suggested to me that I was lactose-intolerant.

This went on for a long time; several years. Lactase or kefir, with milk, in various amounts -- whenever I felt like it. I thought I was proactively managing my apparent lactose intolerance very effectively. And by observation, I was indeed doing so. Keeping active stock of anti-diarrhea pills always nearby was reduced to kind of a fuzzy memory.

---

And then one day, I wanted a nice big ice-cold glass of milk, so I poured myself one. I went to the cabinet in the kitchen, but the lactase bottle was empty. I went to the fridge, and the kefir was gone.

So there I am, with a big glass of milk and nothing to help me digest it.

My health-and-sanitation spidey-sense refuses to let me pour stuff back into containers, and my dread for waste refused to let me pour it down the drain.

So I drank that milk. It was every bit as delicious as I expected.

And I expected (anticipated) the worst, but nothing bad happened. Everything was fine.

One sample isn't a trend, so I had more later. That was fine, too.

Weeks went by, then months. Now years. No issues: Milk goes in, and everything comes out properly.

I can have milk without assistance whenever I want, and that's fine. The previous and clearly-evident pattern that suggested lactose intolerance has become broken.

---

So now I don't have lactase tablets in stock anymore. I still drink the least-fancy milk I can get at the grocery store whenever it suits me.

I do enjoy some kefir from time to time (I love the taste of it), but I haven't had any of that for several months now either.

And I'm still fine. I'm doing really well in that area, really.

I'll leave it to the microbiologists to explain the hows and the whys; that's not my field of study. All I know is that this aspect of my life is way, waaaaaaay better than it was.

I'm very deliberately not providing causation or theories here. This is just my story, and I'm sticking to it.

(Now, someone reading this probably has some questions that are shaped like "Holy hell. Decades? Why didn't you at least go to the doctor or something?"

And that has a simple, dumb-as-bricks, one-word answer: 'Murica.)

Yes. You just eat beans a lot. After a few months it stops making you gassy until you eat a type of bean you have never eaten before and then you are back to square one. Source: vegan who eats beans with 75+% of meals

I was very surprised to see that the article explicitly says it will not consider this answer!

If Dave Arnold says he really doubts it, it's a pretty safe bet he's read like a dozen papers related to the prediction and is basing it on something. He's like the Bunnie Huang of cooking.

My own as-yet-unpublished research suggests that some cultures frown upon excessive comedy in the workplace.

But what if those cultures are just objectively wrong? Farts are hilarious after all.

Early results indicate that the ears say yes, but the nose says no.

>Here I feel the need for an aside. Many, many people will tell you that the key to reducing bean gas is to eat more beans. Eating more beans, they argue, works because it allows our digestive systems, and the microbiome in them, to acclimate to the beans. Over time, they say, the gassiness will go down. This makes no sense to me. If these oligosaccharides are food for bacteria in our gut, common sense would say that feeding that bacteria more food would, if anything, do the opposite by supporting their population growth while giving them plenty of raw material to digest. It wasn't within the scope of this project to test (and, I suspect, disprove) this theory, but count me as highly doubtful. If anything, I have to imagine that eating more beans more often just makes people more used to being gassy, and that, in turn, makes them notice it less. (Their significant others might have a very different take…)

I agree with this in principle but have to point out a few flaws in practice.

First, the immediate product of fermentation is not methane, despite what your high school biology teacher told you. It's hydrogen. In fact, bacteria do not produce methane at all! Only archaea are capable of methanogenesis. This is a rather surprising fact nobody mentioned in school:

https://en.wikipedia.org/wiki/Methanogenesis

>Organisms capable of producing methane for energy conservation have been identified only from the domain Archaea, a group phylogenetically distinct from both eukaryotes and bacteria, although many live in close association with anaerobic bacteria.

So there is some room for error here. When methanogenesis occurs, the volume of gas is reduced by 80%:

4 H2 + CO2 >> CH4 + 2 H2O (l)

But I have never seen any evidence that the amount of archaea or the extent of methanogenesis in the digestive tract varies with diet. However, it does change under certain circumstances, and more methane in enteric gas is generally correlated with less hydrogen:

https://www.jstage.jst.go.jp/article/bmfh/45/1/45_2025-044/_...

>However, methane gas production was not changed by dietary intake, suggesting that intervention with prebiotics may be necessary.

https://iopscience.iop.org/article/10.1088/1752-7155/7/2/024...

>Usually patients produce either hydrogen or methane, and only rarely there are significant co-producers, as typically the methane is produced at the expense of hydrogen by microbial conversion of carbon dioxide. Various studies show that methanogens occur in about a third of all adult humans

(The second study is less optimistic than I am about methanogens reducing intestinal discomfort.)

But there is another thing that can change the amount of noticeable farting: unnoticeable farting. The digestive tract has its own nervous subsystem which reacts to stimuli and processes information. It's plausible that if you produce a lot of gas for a long time, your digestive tract learns to let it out gently. This may reduce irritation of the epithelium.

It's a Portuguese article, but a well known thing in Brazil to leave them in water https://www.nationalgeographicbrasil.com/ciencia/2024/10/voc...

The article mentions they tested this, and it didn't work.

> These tests blew me away. At the very least, I expected that presoaking the beans and pitching the water would reduce fartiness. After all, the sugars are water soluble, so they should leach into the soaking water and get discarded. As it turns out, not so much. I still don’t understand this result.

I don’t buy it. He’s says it doesn’t work but can’t explain why it didn’t work. Could be his method was faulty, the type of bean, the age of the bean, etc.

I rather take the experience of an entire country.

Given the bacterial digestion context here, I wonder how consistent bean consumption affects the gut microbiome? Others have mentioned eating beans a lot is the best way to stop the gas, why is that? is it because the bacteria that digest the indigestible substance are well-hardened and numerous (I'd expect more, not less gas, but perhaps it has to do with the digestive efficiency resulting in less "bubbles" of air that make an audible sound?), or is it because those bacteria die off after being overworked, and you just pass on the indigestible substance unprocessed?

can confirm. worked in a very small office with a guy who didn't give a damn. silent but deadly doesnt do it justice. between that, a single bathroom right across from the secretaries desk (the unfortunate lady she was), and the sound of coworkers breathing, it was unbearable to say the least
