The portobello is the largest member of the cremini family of mushrooms. The smaller cremini mushrooms are harvested younger while Portobellos are allowed to grow longer and therefore larger. Mushrooms support the immune system and protect against cancers. The very high levels of Zinc helps boost the body’s immune function such as wound healing and cell division. The body’s ability to produce antioxidants is enhanced by the selenium in portobello mushrooms, and hemoglobin synthesis (needed for the transportation of oxygen through the blood stream) is supported by the iron and copper in mushrooms. Portobello mushrooms have a high level of riboflavin which gives healthy support to cellular energy production. Adrenal gland function is supported by the pantothenic acid in portobello mushrooms. A reduced risk of Alzheimer’s disease has been linked to the high amounts of niacin found in portobello mushrooms.
