Added Golden Carrots
Golden carrots being used for potions of night vision is based on the common misconception (promulgated by the British government during World War II) that eating carrots can improve one's vision (mostly in the form of being able to see in the dark). This is only true if one has a vitamin A deficiency.
Golden carrots may be the most beneficial (magical effects excluding) food item so far: their effective food + saturation value is 20.4, just a bit less than that of steak (20.8), and they are 1.5 times as nourishing, meaning one will spend a greater fraction of time in a saturated state with health regeneration on.
