Scientists See Cancer-Fighting Benefits In Phytochemical-Enriched Broccoli, Tomatoes

May 14, 2010: 08:15 AM EST
Enriching pre-harvest broccoli with selenium increased the levels of cancer-fighting enzymes in a rat study conducted by U.S. researchers. The scientists tried different bioactive components, but found that a powder made from selenium-treated broccoli boosted the levels of detoxifying compounds six fold. Broccoli and other plants of the brassica family contain a methylating enzyme that allows them to store large concentrations of selenium. The human body needs a certain amount of selenium, but many soils around the globe are deficient. Broccoli enhanced with selenium could be a great vehicle for delivery of the important phytochemical. The researchers are also conducting experiments to determine the bioactive effects of carotenoid-enriched tomatoes.
