No, mushrooms are not fruit or vegetables. In fact, they are not plants at all.
They evolved at a different time to plants (Carroll 2001). This helps to explain why the mushroom has a different nutrition profile to fruit and vegetables.

In fact, the latest research indicates that it is a smart decision to eat mushrooms daily as they influence blood lipids, blood glucose, immunity and weight control, and offer many essential nutrients and antioxidants. So, rather than eating five vegetable serves a day, try eating four serves of vegetables and one serve of mushrooms for good health.
