it’s so common, there’s a reason comedians joke about eating them and farting

The average American eats a dearth of fibrous vegetables.

The article you quote literally says what I said, so I’m not sure what you’re getting at. Your quote even points out that beans are not the only fibrous vegetable that causes gas when you don’t regularly eat enough fiber (brocolli is another non-legume example). If you kept reading, you would see:

Fiber is particularly difficult to digest compared to some other foods. If you suddenly start eating 1 cup of beans per day, that’s a big increase, and it may take some time for your body to get used to your new fiber intake. But as you continue to consume legumes regularly, your gas levels will eventually return to normal.

Btw it’s beans AND legumes in general that do this

Yes, beans are legumes, that’s why we’ve been using the word legume this whole thread

Sure, but your explanation being completely incorrect damages your credibility

The amino acids in plants come from proteins, too

it’s nasty af and makes most people’s stomachs bloated and inflammed

You never eat vegetables, do you? Much of the world lives off legumes. Having these issues with their digestion is caused by a poor gut microbiome from eating an extremely low-fiber diet.
