It’s the extra dietary fibre. Your body is absorbing the nutrients it needs but can’t digest the fibre - this is fine and normal. Luckily, you have plenty of gut bacteria that LOOOVE fibre and can even help protect you from other illnesses and help get different nutrients into you. The tradeoff is they fart a lot on it, which makes you fart a lot.
A lot of non-vegan western standard diets are very short on fibre (people literally just need to eat more veggies and theyd be fine). Hence the infamous GI changes, bigger poops, farting that comes with starting to eat vegan. It’ll work itself out to something more normal, I swear lol
I’d like to read or watch one of those stories, just once, so I can decide if I actually like it. Cause it’s a cheap way of showing how a character has grown, they started off wanting revenge and now they’ve transcended that and see how far they’ve gone on their arc? I liked the bit in Princess Bride so maybe it’d be good in general
