I highly recommend anything he works on.
Soak and rinse, but the soak water should be boiling when the dry beans go in.
Alkaline. Sodium Carbonate (baking soda) or calcium hydroxide (lime) work. Throw away the cooking water. This has to be done carefully, as too much of either can give the food a mineral taste and/or dissolve the beans entirely.
Fermentation also works. Lactic acid (like kimchee or pickles) helps a little. Koji (either added or grown on the beans themselves) helps a lot. Both will have a big impact on the flavor and what the beans will be good for in the end.
What’s koji?
In many parts of Africa the ultimate solution is to peal the skins off the beans. This removes all digestive issues with bean consumption but it's a lot of work.
Another solution is to uses the microbe Aspergillus by consuming Miso paste with the beans which help break down indigestible polysaccharides.

But on a more serious note, does that actually work, even if just a bit?
What causes this? Gut microbiome adapting? Doesn't that imply there should be some probiotic-type supplement you can take to seed these bacteria and keep them alive even when not eating beans?
Unscientifically, it feels like your gut microbiome adjusts to it after a while!
For the impatient: they found no common cooking technique that helped significantly reduce - as they call it the “fartyness” of the beans..
Cultures around the world have been sprouting and fermenting forever, but most people have forgotten it.
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.

Made me laugh : )
Those episodes are really fun and always result in me eating more beans!
Rancho Gordo beans are great! Yellow Eyes ftw.
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:

>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.
