'Superfoods' shown to fight prostate cancer Diets rich in polyphenols, the natural plant-based phytochemicals found in healthy foods, have been linked with lower risks of chronic illnesses such as dementia, high cholesterol, arthritis, heart disease, skin aging and macular degeneration. Studies have also linked their regular intake with lower risks of many cancers including breast, pancreatic, oesophageal, ovarian, prostate, and skin cancer. Research has also found that breast cancer survivors eating polyphenol-rich fruit, vegetables, soy and green tea were found to have lower relapse rates. The anti-cancer effect of polyphenols works because of their anti-oxidant properties, which protect the DNA from oxidative damage from carcinogens. The substances also work by killing cancer cells and inhibiting their proliferation. Professor Thomas said: "Our experience in offering high-quality clinical care, collaboration with cancer charities and world-class research with the University of Cambridge has resulted in findings which will have an world-wide impact. We hope this will help millions of men to help combat the onset of prostate cancer. The study found virtually no adverse affects among the group who were given the supplement. Because of the lowered PSA levels among those given the capsule significantly fewer men proceeded to potentially toxic therapies at the end of the study, the study said. "Healthy eating and lifestyle is the main way of helping to combat the development of cancer but men can now also turn to a whole food supplement which has been shown to work," said Prof Thomas.
