In the last decade, several diseases understood as strictly noninfectious have, in fact, been found to have significant infectious components. Several forms of cancer, gastrointenstinal diseases, autoimmune illnesses including diabetes, and even some categories of heart disease are all being reconsidered in light of new research. Together, this research amounts to nothing less than a new germ theory, one that could once again alter contemporary definitions of medicine.
Almost everything I talk about is in there. His atherosclerosis explanation is indirect and ignores direct microbial processes that have been documented for decades, but it's a good start...
(I do have one "small" quibble though- this is not a new Germ Theory of disease, it's the same old theory. Do not give doctors a pass on that- they have been negligent, working off flying-ass-monkey assumptions, and ignoring their terrible results for half a century.)
