New research reveals additional clues to the mechanism behind tomatoes' known protective effect against prostate cancer (Mossine VV et al. Cancer Res. 2008;68:4384-4391).
Investigators at the University of Missouri-Columbia, and colleagues demonstrated that FruHis, a carbohydrate derivative present in dehydrated tomato products, exerts this effect.
Rats were divided into groups of 20 and fed a control diet or a diet that included tomato paste, tomato powder, or tomato paste plus additional FruHis. All animals were then treated with N-nitroso-N-methylurea and testosterone to induce prostate carcinogenesis.
