"Anybody that knows beans about chili, knows you don't put beans in chili"
:-)
I do not eat beans at all. Beans, and the subsequent gas issues they create, in addition to their fiber content, causes "explosive" issues that have even resulted in surface bleeding and very uncomfortable (think "machine gun") movements.
I grew up eating copious amounts of them, you could say they have been my "peoples" ancestral food for the past 300 years or so (Southern Appalachian American (Hillbilly) here, most family lines pre-revolutionary), and despite any short-term epigenetic/ancestral adaptations, they have still caused me significant issues... even pre-paleo (but much worse now).
In other words, beans are a comfort food going in, and, well... not so much comfort otherwise. I would probably risk gluten before I risk beans.
Some "fresh" legumes such as peas, snap beans, and lima beans have not caused me significant issues, but the higher-protein dry beans such as kidneys, lentils, pinto beans, broad, and navy beans have always done this - in practically any quantity.
It's a shame, I grew up in a household where $2 worth of dry beans (soaked for 24 hours in water and baking soda or vinegar), a $3 smoked ham hock, and a skillet full of cornbread could feed a family of 10. Despite living in squalor most of my formative years, I was never hungry.
