Why do scientists believe oral insulin may help to prevent or delay type 1 diabetes?

In brief: We don't know why

The research done in sweden showed a delay in the onset of type 1 diabetes in patients with Insulin autoantibodies given oral Insulin crystals daily for several years, but who weren't diabetic yet.
The finding was unexpected, researchers were looking to prevent it altogether which it didn't. See http://www.Sciencedaily.Com/releases/2012/09/120919083412.Htm.

In brief: Immunomodulation

Type 1 diabetes is thought to occur in genetically-susceptible patients whose immune system attacks their own pancreatic cells following some environmental factor that triggers their immune system. Insulin was thought to help delay or slow the progression of this process by modulating the immune system. However, so far, Insulin does not seem to do this in large clinical trials.
