Beans contain a category of sugar called oligosaccharides. The types you find in garbanzo include raffinose, ciceritol, and stachyose (4). Unlike grains, these are hard for our bodies to digest.
They are too large to be absorbed in the small intestine, so they pass on through to the large intestine – where your gut flora will ferment them to break them down.
This fermentation results in the production of gas, including hydrogen and methane (which smells awful). While some people fart less than others after eating chickpeas, no one gets a free pass.
This is because all humans lack the enzymes necessary for digesting them any other way. Many mammals can break them down just fine – with 100% of it occurring higher up in the small intestine (5). But we as humans can’t and never will be able to.
The real answer is like food. The answer isn't in eat-all-of-this and none-of-that. Being gluten-free isn't going to transform you overnight. Going meat-free isn't either. The answer to accumulating wealth isn't just "save money" but also "cut expenses". And this means a little of this, and a little of that - and constantly evaluating what you are earning, saving, and spending - and realizing you will make mistakes over time.
But over time, things accumulate. Moss grows on a rolling stone. And wealth accumulates.
I'm not saying I'll never have falafel again. But maybe next time, just a little bit, instead.
