    Compounds isolated from broccoli could provide a new weapon against
    bladder cancer, new research has shown.

    A previous study found that eating the green vegetable could help
    protect people from the disease.

    Men who ate two or more half-cup servings of broccoli were 44% less
    likely to suffer the disease than those eating fewer than one serving a
    week. Now the same team of scientists has identified the chemicals in
    broccoli that are thought to inhibit bladder cancer.

    A total of 11,000 people are diagnosed with bladder cancer each year in
    the UK, and just over 3,000 people die from the disease.

    The American researchers isolated compounds called glucosinolates from
    broccoli sprouts. During chopping, chewing and digestion, these
    chemicals are transformed into nutritional powerhouses called

    The scientists suspected that these played a role in inhibiting bladder
    cancer. In at least three laboratory experiments, they were proved
    right. Isothiocyanates slowed the growth of bladder cancer cells, and
    had the greatest impact on the most aggressive cancers.

    The findings were presented at a recent meeting of the Institute of
    Food Technologists in New Orleans.

    Young broccoli sprouts naturally have higher concentrations of the
    compounds than full-grown vegetables. But eating adult broccoli spears
    could also provide health benefits, said Prof Schwartz.

    Dr Steven Clinton, another member of the research team, said at least a
    dozen compounds in broccoli may have anti-cancer effects, adding:
    "We're now studying more of those compounds to determine if they work
    together or independently, and what kind of effects they have on cancer

    Other cousins of broccoli, including cabbage, cauliflower, Brussels
    sprouts and kale, may contain similar cancer-flighting plant chemicals,
    the researchers believe.
