Well, I don't eat margarine or any other product that contains transfatty acids, hydrogenated fats, or anything that sounds too far removed from its natural state. And if it isn't edible in its natural state, I won't eat it in its processed state. And Quorn isn't mushroom, it's a fungus that's grown in vats under controlled conditions. I mean, it doesn't matter to me whether others eat it, I've just decided not to eat it.
