CELERY is known for its dietary properties, and carrots apparently help you to see in the dark... but they could also both hold the key to slowing the growth of colon cancer, researchers say. They have found that luteolin - a flavanoid, or antioxidant, found in fruit and vegetables - can block cell signal pathways vital for the cancer’s growth. Luteolin can also be found in olive oil, green peppers, thyme, chamomile tea, peppermint and rosemary. However, more research is needed to find how the compound could be developed into an effective anti-cancer agent. Previous lab tests have revealed luteolin’s antioxidant and anti-cancer properties, although further tests were less certain. –DM
