Known as the 'elixir of life' since ancient times shiitake mushrooms are an immune booster
Shiitake mushrooms are rich in iron, a mineral which is essential for maintaining good health. Iron improves the circulation of oxygen through your blood. As a result, oxygen and other nutrients are effectively supplied to your muscle cells, brain and other parts of the body. Iron is also used to treat anemia, so if you are anemic as a result of menstruation or pregnancy, make sure you incorporate plenty of shiitake mushrooms into your diet.
