Mushrooms have the highest concentration of iodine. The content of nutrients found in mushrooms is out of this world. 30-40% of their dry weight is protein (meat is 15-25%). Mushrooms contain about all the minerals necessary for the human body, and vitamins A,B1,B2 and vitaminsC and D. Therefore create massive brain stimulation. And sure enough they look like a brain with a stem like our spine. If you are suffering from anemia and/or physical and intellectual fatigue mushrooms are your new best friend! Great for people who are trying to reduce their meat consumption and vegetarians and vegans.
