Fact: There are excellent reasons to cook up some mushrooms – just don’t expect them to deliver too much vitamin B12.   The main sources of this essential vitamin are animal foods like meat, fish, poultry and dairy products -this makes it difficult to get B12 from a vegan diet that excludes these foods, although some manufactured foods and soymilks are fortified with B12.

Mushrooms, the only natural plant source of vitamin B12, are often claimed as a good source of this vitamin but one serve (100g -the equivalent of three average size button mushrooms) provides no more than five per cent of the daily requirement, says the Australian Mushroom Growers’ Association.
