It is eaten like a vegetable, yet the part we eat is called a “fruiting body”, with most of the mushroom growing underground in what is called “mycelium”. But the mushroom is neither a fruit nor a vegetable. All mushrooms come from a completely different living kingdom, the mushroom kingdom, or what we call the “3rd Food Kingdom”.
Because it is from a different food kingdom, the mushroom has a very different nutrition profile and has antioxidants and bioactive compounds not found in plants. For example, it has more B vitamins that found in vegetables, it is a good source of essentials mineral like selenium and has powerful antioxidants like ergothioneine.
