PhytochemicalsPhytochemicals are substances produced by plants to help protect them against microorganisms such as fungi and viruses. Unlike vitamins and minerals, phytochemicals have no known nutrient value. Nevertheless, scientists are intently studying phytochemicals based on the possibility that they may help prevent cancer. Numerous studies have shown that eating a diet rich in plant foods protects against certain cancers, including prostate, bladder, colon and rectal cancers. Different phytochemicals differ in their mode of action. Some, such as those found in broccoli and cauliflower, appear to act by blocking cancer-causing agents from damaging a cell’s genetic material. Others, such as those in beans and lentils, apparently work by directly interfering with the cancer cell’s ability to multiply. « Back |
