(London Daily Mail) Fashionable anti-cancer superfoods and supplements do not prevent the disease and may even cause it, according to a scientist who helped discover the structure of DNA.

James Watson said the cure for many cancers will remain elusive unless scientists rethink the role of antioxidants, which include vitamin pills and food such as blueberries and broccoli.

It is widely believed they boost health and fight cancer by mopping up oxygen molecules called free radicals. But Dr Watson argues these may be key to preventing and treating cancer – and depleting the body of them may be counter-productive.
