Cruciferous vegetables contain other nutrients and phytochemicals that make them potential anticancer agents. These phytochemicals which belong to the group known as isothiocyanates are the 3,3′ diindolylmethane, sulphoraphane, and selenium. With these vitamins, minerals and phytonutrients, the cruciferous vegetables help to lower the risk of diseases such as cancer and cardiovascular disease; they are both preventive and curative. These vegetables do these in the following ways:
1. They stop the growth of cancer cells in tumours of the breast, endometrium (the inner lining of the womb), lung, colon, liver and cervix.
2. The phytochemical, sulphoraphane stimulates enzymes in the body that detoxify carcinogens before they cause damage to the cells.
3. They reduce oxidative stress (overload of free radicals which destroy cells and their contents – DNA, causing cancer).
4. In combination with fish oils, the cruciferous vegetables help to protect against cardiovascular diseases.
