Mushrooms And Green Tea Cut Breast Cancer Risk?

A mushroom a day keeps the oncologist away.

The researchers found that women who consumed the most fresh mushrooms, 10 grams or more daily, were roughly two thirds less likely to develop breast cancer than those who consumed no mushrooms. Furthermore, those who ate 4 grams or more of dried mushrooms daily halved their cancer risk compared with women who ate no mushrooms.

The results showed that mushroom eaters who also consumed green tea everyday had only 11-18 percent the risk of breast cancer of women who consumed neither. However, the researchers emphasize that the study does not prove a cause-and-effect relationship.

On the one hand I argue against trying to eat a few superfoods as a substitute for a generally good diet. On the other hand, these are dramatic results. Keep in mind though, that lots of other diseases kill people. You can't just focus on cutting the risks of one or two diseases. Here's the abstract.

Mushroom extract is getting tested in California to see if it'll cut the recurrence of breast cancer.

Last month scientists in California began a trial to see if taking a mushroom extract twice a day for a month helps breast cancer survivors remain free of the disease.

Mushrooms aren't just for girls. Mushrooms might also cut the risk of prostate cancer too.

In their quest to find new ways to fight cancer, researchers are increasingly turning to nature. They’re discovering that many of the vegetables we regularly consume in our diet —notably mushrooms—are potent cancer killers. A new study in the journal Nutrition and Cancer finds that the white button mushroom is particularly effective against prostate cancer.

A number of different mushroom species have been investigated for their cancer-fighting properties. “I think mushrooms, and especially medicinal mushrooms, are being used to prevent cancer because they potentially have the ability to affect immune function in our bodies,” says study author Shiuan Chen, PhD, Professor and Director of the Division of Tumor Cell Biology at the Beckman Research Institute of the City of Hope in Duarte, California.

I would like to know whether cooking cuts the potency of mushrooms as cancer preventatives. Anyone have any idea?

There's always a lose of nutrients after cooking but sometimes cooking can make certain nutrients more readily absorbed like lycopene from tomatoes. I have no idea if cooking mushrooms cuts their cancer fighting potency though. I would like to know too.

Green tea and mushrooms. Sounds like the Japanese diet.

What species of mushroom is typically eaten in southeast China? Is there any reason to assume it's a button mushroom (Agaricus bisporus) like in the United States?

Do we believe this was a clean study? 90% reduction is a crazy number.

I am in my 60's and I have been using 2 medicinal mushrooms for some time: the AGARICUS BLAZEI MURILL (native of Bazil) and the ANTRODIA CAMPHORATA (native of Taiwan). I just had my annual physical test and I am happy to report that my PSA is only 0.4 (no sign of prostate cancer soon). I attribute my low PSA for having been using those 2 mushrooms for a few years now on and off. They are both less known but actually more powerful than most popular medicinal mushrooms. According to research, The Agaricus Blazei Murill is the richest in the active compound found in Medicinal Mushrooms called POLYSACCADIDE. The Antrodia Camphorata is actually a super REISHI. Reishi (Ganoderma Lucidum) nis definitely a great medicinal mushroom which is also more widely available.
Extracts of those mushrooms are sold in capsules, but I recommend to use them as a tea by opening the capsules and mixing the content with hot water. Medicinal Mushrooms love the heat. I've written an article on the subject that I will be very happy to send to any interested person. Here is my email address: sonny_seraphin@yahoo.com.

My experience with reishi, cordyceps, shiitake and the literature and traditiional uses make it seem very unlikely that cooking lessens potency. Mushrooms have hard chitin-like skin (esp reishi) and both grinding and cooking (1/2 - 1 hour simmer) is required to extract medicinal properties. Aromatics, which are lost in heat, are not a feature of fungi; polysachharides, beta-glucan, flavonoids, seem to be heat-stable. Antivirals from cordyceps (adenosine analogues, some already used as anti-HIV drugs, others similar in action to Ribavirin, an anti-HCV drug, plus adenosine itself, which acts as an antidote in healthy cells but does not protect virus or cancer replication) are destroyed by extreme heat and cannot be dried out, but these are not in other mushrooms. Best way to prepare cordyceps is to soak overnight in hot water, drink water, chop and prepare by boiling for 1 hour. This gets both heat-labile and heat-stable extracts.

In my post of 27 May 2009, please read that the AGARICUS BLAZEI MURILL IS NATIVE OF BRAZIL.

Also read that "ACCORDING TO RESEARCH THE AGARICUS BLAZEI MURILL IS THE RICHEST IN THE ACTIVE COMPOUND FOUND IN MEDICINAL MUSHROOMS CALLED "POLYSACCHARIDE" in the form of Beta (1,3)-D Glucan and Beta (1,6)-D Glucan.

Please also read that ANTRODIA CAMPHORATA IS a Super Reishi. "REISHI (GANODERMA LUCIDUM) IS DEFINITELY A GREAT MEDICINAL MUSHROOM, WHICH IS MORE WIDELY AVAILABLE.

MEDICINAL MUSHROOMS are the first line of defense against cancer in Japan, more specifically the Agaricus Blazei Murill.

Medicinal Mushrooms don't attack the cancer cells directly but instead stimulate the Immune System, more specifically the white blood cells, macrophages, and natural killer cells (NK-C cells) to engulf and destroy the cancer cells and free radicals. Quite interesting!
