There are numerous other phytochemicals that do this, too.
They are: Bioflavonoids, found in carrots, melons, prunes, citrus fruits and berries (in particular blueberries such as the European bilberry). The bioflavonoids keep almost all cancer-producing hormones from latching onto normal cells initially so that they are not predisposed to mutagenesis (abnormal cell division).
Genistein, constituting a considerable portion of soybeans, kills malignant tumors by preventing the formation of those capillaries usually needed to feed them. Thus, genistein exhibits an anti-angiogenesis effect that eventually starves tumors out of existence.
Indoles, chemical components in cruciferous vegetables such as Brussels sprouts, cauliflower, and cabbage, increase immune activity and make it easier for the body to excrete toxins from cellular deposit sites such as adipose tissue.
Saponins, present in kidney beans, chickpeas, soybeans, and lentils stop cancer cells from multiplying. They are any of numerous glycosides, derived from sugars, Saponins are characterized by their ability to foam in water, their physiological effect is to reduce blood cholesterol to normal.
Chlorogenic acid and P-coumaric acid, a part of tomatoes, interfere with certain chemical unions which create carcinogens. In fact, tomatoes contain an estimated 10,000 different phytochemicals, the most important being the antioxidant lycopene.
Phenethyl isothiocyanate (PEITC), found in cabbage and turnips, inhibits the growth of lung cancer and protects the cellular DNA from a potent carcinogen that makes up much of the toxins in tobacco smoke.
Almost all grains, legumes, fruits, and vegetables known to nutritional scientists and tested in laboratories around the world have been confirmed to contain the beneficial phytochemicals mentioned and many more. Indeed, it's likely that hundreds of thousands of phytochemicals do exist, and they merely need to be identified to establish their individual advantage for humankind.
A Lancet Published Report on Colored Fruits & Vegetables
The British medical journal, The Lancet, tends to verify the truth of the above-cited Australian study by publishing the American university-based findings of a Danish scientist, William Hart, PhD, RD. Dr. Hart teaches courses in biochemistry and human nutrition as an associate professor of nutrition and dietetics at Saint Louis University in St. Louis, Missouri. He emphatically writes, "The bottom line is to forget nutritional supplementation with pills and instead eat good foods consisting of lots of whole grains, fresh fruits, and fresh vegetables. To thrive, you should limit the intake of meat, high fat milk products, and all other sources of animal fat."
Dr. Hart's report in The Lancet examined 20 years of his research on people believed to be at high risk of developing gastrointestinal cancers who used antioxidant supplements in pill form. His anti-pill studies were carried out on capsules and tablets containing selenium and other minerals plus the vitamins A, C, and E. He labelled the taking of vitamin pills "useless" in preventing common digestive cancers. But Dr. Hart added that more study is needed on whether selenium can fight liver cancer.
"This research confirms what I have been saying during my whole professional career in nutrition," says Dr. William Hart. "Eating a good diet with lots of whole grains, highly colored vegetables with fresh fruits, and limiting meats and fat is the best way to ensure that you maximize your own genetic potential to avoid or delay all sorts of chronic diseases."
It turns out that eating full quantities of whole grains, the usual green leafy vegetables, plus elevated amounts of colored fresh fruits and vegetables not only furnishes you with a healthy homeostasis to ward off illness, but such phytochemical ingestion is therapeutic, too.
