* [[Inulin]] appears to lower the risk of Colon Cancer, of course more research needs to be done. Please do not confuse Inulin with Insulin for they are two different things. Plants that contain high concentrations of inulin include: [[Elecampane]], [[Coneflower]] Echinacea spp, [[Dandelion]], [[Wild Yam]], [[Jerusalem Artichoke]], [[Chicory root]], [[Jicama]], Burdock, [[Costus]] Saussurea lappa, Mugwort [[Artemisia Vulgaris]], [[Onions]], [[Garlic]] (Allium sativum), [[Agave]], [[Leopard's Bane]] [[Arnica]] montana, [[Yacón]], Camas.
* Sweeter than onions, [[leek]] contain allyl sulphides that help protect against many types of cancer, particularly colon and [[Prostate Cancer]].
* [[Vitamin B3]] : Niacin, or B3, works to reduce inflammation even if you’re not getting enough fiber. It keeps polyps from forming in the first place. And if you already have them, it keeps them from getting larger.
*[[Limonoids]] have shown cytotoxicity to breast cancer, colon cancer, pancreatic cancer, liver cancer, neuroblastoma, leukemia, melanoma and non-small cell lung cancer.
* [[Apples]] : Oligosaccharides from apples (pectin and other fibers) killed up to 46 percent of human colon cancer cells in vitro
