Harvard’s Science of Cooking program co-tested 17 common remedies for bean-related gas and found no cooking technique made a significant difference.
Key Takeaways
Tested 17 remedies in partnership with Harvard’s Science of Cooking program, making this more rigorous than typical food-journalism trials.
Gas is caused by FODMAPs, indigestible sugars that gut bacteria ferment; the study framed remedies around this mechanism.
No common preparation method, soaking approach, or additive meaningfully reduced what the authors call “fartyness.”
The source preview implies the article identifies what does work, but based on commenter consensus the answer is primarily repeated exposure over time, not a technique.
Hacker News Comment Review
Strong commenter consensus: consistent bean eating over several weeks reduces gassiness, but the effect is bean-type-specific and resets when switching to an unfamiliar variety.
Commenters pointed to Brazil as a natural experiment: daily black bean consumption at population scale with minimal reported gassing, which undermines the article’s framing that no reliable solution exists.
Sprouting beans before cooking, which converts stored FODMAP sugars during germination, was flagged as an obvious hypothesis that the researchers apparently did not test, a notable methodological gap.
Notable Comments
@tmoertel: argues sprouting was the obvious missing test given the FODMAP mechanism the article itself describes.
@BoppreH: cites Brazil’s daily bean culture as evidence the “eat more beans” adaptation theory deserves serious reconsideration.
