Frequently Asked Questions by new mushroom cultivators

Are mushrooms fruit or vegetable?    

Neither actually. Fruits and vegetables are members of the plant family. Mushrooms evolved later, just before the evolution of animals. Being different to fruit and vegetables helps to explain why mushrooms contain more B vitamins, vitamin D, selenium, and the antioxidant ergothioneine than found in fruit and vegetables. The mushroom is truly different to fruits and vegetables, yet is able to wonderfully complement the benefits they offer.

Can mushrooms prevent you from getting cancer?
   
We don’t know for sure, but there has been some very interesting research of late showing that mushrooms influence specific enzymes in the body and could be playing a role in reducing the risk of both breast and prostate cancer.
Research conducted at the University of Western Australia showed that women who regularly ate an average of 10g of mushroom a day reduced their risk of breast cancer by over 60%. Ten grams is less than one button mushroom. Further research is being conducted in the US to see the effect of eating mushrooms on cancer development.
With the mushroom being high in antioxidants, essential nutrients, fibre and selenium, we feel confident that mushrooms are helping to enhance the health of all Australians.

Do mushrooms contain vitamin B12?    

Australian government laboratories tested the mushroom in 1987 and found that a serve of mushrooms provided about 10% of the daily needs of vitamin B12. Since then there has been speculation whether this was a correct level, or the right type, of B12.
To accurately establish the levels of B12 in mushrooms, scientists at the University of Western Sydney have checked mushroom samples from all the major mushroom growing centres around Australia in 2009.
There is a modest amount of B12 in mushrooms, closer to 5% of daily needs in a serve (three button mushrooms). It is the same type of B12 as found in meats and seafood, so it is the type of B12 that the body finds very easy to use.

Do mushrooms contain vitamin D?    

Mushrooms are the only non-animal fresh food source of vitamin D. High levels of vitamin D has been found naturally in mushrooms in the field. That means that leaving mushrooms in the sunshine for a short time dramatically increases the vitamin D levels.
The Australian mushroom industry, with help from the University of Western Sydney and Pennsylvania State University, have been testing to see how much light is needed to provide the daily needs of vitamin D in a serve of mushrooms (three button mushrooms).
Now that the trials have been completed, the mushroom industry is looking to find a commercial way to make vitamin D enhanced mushrooms available at the supermarket to help Australians easily get their vitamin D needs.

How much mushroom should I eat each day?    

A 100g serve will provide all the nutritional benefits available from a mushroom. That works out to be about three button mushrooms, or one medium flat mushroom, a day. Easy.

Is it true that mushrooms have antioxidants?    

Yes. In fact, when compared to commonly eaten vegetables, they are in the top five for antioxidants.
Recently, mushrooms were found to be the best source of the antioxidant ergothioneine. As humans have a special protein to transport ergothioneine in the blood, it has been speculated that humans have naturally long been mushroom eaters. Ergothioneine is involved in keeping red and white blood cells healthy.

What is the GI of a mushroom?    

The Glycaemic Index (GI) of mushrooms is close to zero. The GI of foods is a measure of their effect on blood sugar levels. As mushrooms have virtually no carbohydrate, they do not raise blood sugar levels, which is good news for everyone, as well as those with diabetes.
