Okay, I am probably of a minority, but beans do not make me fart a lot. Maybe just a bit in passing, but I've noticed since I've given up meat and adding more beans to my diet instead, I do not get as gassy as when I ate them less before becoming veggie. Getting used to them, I guess. I can especially eat pintos with very minimal tooting.
I take presciption stomach medication and sometimes this med causes me to get gassy and bloated, so I try to not add to the discomfort. I was hoping a another benefit of a vegetarian lifestyle would be easing my stomach acid reflux disease so I could get off the med, but I am finding certain soy products are not my friend! However, I am thinking that soon I can go back on over-the-counter med, and my doctor said I should stop eating meat and drinking so much fluids. Veggies do not back up on me the way some things did, such as bacon, and my dinner is not backing up on me the way it used to since I've stopped eating meat. Doctor told me the meat is one culprit of back-up due to how long it takes the stomach to break it down. Huh... Anyway...that's a story for another thread.
However, I take the gas-iness in spurts and have been narrowing it down to a few culprits... If I eat large amounts of cucumbers, unless they are what my mom calls "belchless" cucumbers, which she grows in our backyard garden in summers. If I eat large amounts of raw veggies such as cucumbers, carrots and celary together.
When entertaining in their homes, all of my family members put out large trays of raw veggies for the holidays (as well as crackers, cheese and chips n' dips) and I'm the biggest raw veggie eater of the family (I'll even eat raw potatoes of all sorts!) and usually the one chasing people out of the room with "silencers"
...it's always been that way, even before I became veggie.
Another problems seems to be soy, but in not in all forms. Some of the faux meat products cause me problems if I eat them a lot; however, so far, Tofurkey products I've tried so far do not give me gas, nor do the Boca vegan burgers. So I recently went shopping and when I purchased my faux meats I purchased Torfurkey and Boca products to try their other concoctions.
One other small thing, sometimes, if I eat too many raw apples in a day, I will belch alot... but farting is not a side effect... LOL! Thank goodness!
