The John Hopkins School of Medicine, based in Baltimore, has been awarded a US patent for its new invention "cancer chemoprotective food products." The invention relates to a dietary approach to reducing the level of carcinogens in animals and their cells and thereby reducing the risk to the consumer of developing cancer. In particular, it relates to the production and consumption of foods that are rich in cancer chemoprotective compounds.

Protected under US patent number 6,242,018, the abstract reads:

    Vegetable sources of cancer chemoprotective agents have been identified which are extraordinarily rich in glucosinolates, metabolic precursors of isothiocyanates. The vegetable sources are used to provide a dietary means of reducing the level of carcinogens in mammals.

The first claim (of 12) is for:

    A method of preparing a food product rich in glucosinolates comprising cruciferous seeds, flour made from the cruciferous seeds, or a combination thereof, wherein said method comprises introducing cruciferous seeds, flour made from the cruciferous seeds, or a combination thereof, into another edible ingredient, wherein said seeds and flour are rich in glucosinolates.
