"Certainly, the bacteria issue is complex. In a slew of recent papers in high-profile science journals, researchers associated with the Human Microbiome Project [hyperlink added] have begun to reveal how the ecosystems in our digestive systems, on our skin and throughout our bodies can influence our health in a surprising number of ways, from our risks of obesity to our chances of developing rheumatoid arthritis. The bacteria that inhabit us outnumber our own cells ten to one, and advocates of raw milk often bring up the microbiome to explain why pasteurization is a bad idea. While the heating process may kill harmful bacteria that can cause complications ranging from diarrhea to death, they argue that pasteurization also destroys potentially helpful probiotic bacteria as well as important enzymes and vitamins that help our bodies fight off pathogenic bacteria and digest fats and calcium, among other nutrients."
