Eating a daily portion of mushrooms could slash the risk of breast cancer by up to two-thirds, according to new research.
Scientists found women consuming a third of an ounce of fresh mushrooms every day were 64 per cent less likely to develop a tumour. Dried mushrooms had a slightly less protective effect, reducing the risk by around half.
The study, carried out in China, also showed women who combined a mushroom diet with regular consumption of green tea saw an even greater benefit. The risk among women in this group was reduced by almost 90 per cent.
Researchers say the latest findings, published in the International Journal of Cancer, do not prove eating mushrooms will stop cancer and more studies are needed to confirm the results. But laboratory tests on animals do show the fungi have anti-tumour properties and can stimulate the immune system's defences.
