More on the benefits of intestinal bacteria, which conversely implicates antibiotics as a cause of cancer, IBS, IBD, Crohn's, etc - http://www.sciencedaily.com/releases/2009/02/090205214418.htm


"Bacteria naturally present in the human gut could produce substances that help to protect against colon cancer and provide therapy for inflammatory bowel disease. In a paper published in the journal Microbiology, researchers from the University of Aberdeen Rowett Institute of Nutrition and Health and from the MTT Agrifood Research Institute in Finland report initial studies showing that bacteria in the human gut convert linoleic acid, a naturally-occurring fat in the diet, into a form called conjugated linoleic acid (CLA) which is absorbed by the gut wall.

There are different types of CLA and not all of them have beneficial effects. The "good" form of CLA is present in dairy foods such as milk and cheese," said Dr John Wallace of the Rowett Research Institute, "but eating lots of dairy foods won't necessarily help our gut health as most of the fats are digested in the small intestine before they get to the large intestine, where most of our gut bacteria are found."

Note that they state that the good CLA is found in dairy foods. A good way then to protect against cancer and inflammatory bowel disease would be an enema of organic raw milk and cream, as promoted by Aajonus Vanderplanitz.
