Does MAP Cause T1D or Does T1D Cause MAP?

According to a study by the University of Sassari, Italy, 63% of those with T1D were found to have tho MAP (Mycobacterium avium subspecies paratuberculosis) bacteria circulating in their blood stream. Only 16% of those without T1D were infected.

63% is only slightly more than half, yet a high number considering that current testing methods appear to leave many cases of MAP undetected. It may be that all (or at least more) people with T1D are infected with MAP.

“But just because being infected and type-1 diabetes appear to go together,” says Dr. Micheal Greger in the following video, “we don’t know which came first. Yes, maybe infection made kids more susceptible to diabetes; but maybe the diabetes made kids more susceptible to infection. Maybe this bug just likes hanging out in sugary blood.”

To find out what was the case, a similar test was run on those with type-2 diabetes. You can watch the following short video to see the results. You’ll also learn:

  • The probable reason why the MAP bacterium is disguising itself as beta cells.
  • Which specific gene may make people with T1D more susceptible to a MAP infection.
  • Two theories why MAP infection of East Indians with T1D is very rare (or at least seems to be).
  • The (disgusting) way meat and milk get infected with MAP and how to thwart itv“
