New Scientist Breaking News - Mystery compound in beer fights cancer

Some cancers are caused by heterocyclic amines, DNA-damaging chemicals found in cooked meat and fish. When Sakae Arimoto-Kobayashi's team at Okayama University in Japan fed these chemicals to mice, the DNA damage to their liver, lungs and kidneys was reduced by up to 85% if the mice drank non-alcoholic beer instead of water.

Arimoto-Kobayashi thinks as-yet unidentified compounds in lager and stout prevent the amines binding to and damaging DNA. If these compounds can be identified, brewers might be able to produce beers particularly rich in them, or they could be added to foods.
