" Scientists say they have discovered how vegetables such as broccoli and brussels sprouts can prevent cancer.  The team from Georgetown University in the US say a chemical found in cruciferous vegetables such as broccoli can boost DNA repair in cells, potentially stopping them from becoming cancerous.  The researchers found the vegetables contained a compound called 13C and a chemical called genistein. In tests they were shown to boost the amount of essential BRCA proteins in the body.  BRCA proteins prevent damaged genetic information, such as cancer, from being passed on to the next generation of healthy cells.  Since low levels of essential BRCA1 and BRCA2 proteins are found in cancer cells, the scientists suggested that by increasing the levels of the proteins, cancer could be prevented from developing.  Professor Eliot Rosen, who led the research, said: &amp;quot;Studies that monitor people&amp;#039;s diets and their health have found links between certain types of food and cancer risk.  &amp;quot;However, before we can say a food protects against cancer, we have to understand how it does this at a molecular level.&amp;quot;  &amp;quot;It is now clear that the function of crucial cancer genes can be influenced by compounds in the things we eat.  &amp;quot;Our findings suggest a clear molecular process that would explain the connection between diet and cancer prevention.&amp;quot;  The findings were published in the British Journal of Cancer. \u00A9 Adfero Ltd "^^<http://www.w3.org/2001/XMLSchema#string>
