And other studies show that ARBs (angiotensin receptor blockers) are a part of a cure for diabetes, but only part.
I glanced at the thread. I didn't notice anything about ARBs. After looking, I found Single versus dual blockade of the renin-angiotensin system (angiotensin-converting enzyme inhibitors and/or angiotensin II receptor blockers) in diabetic nephropathy.
"RECENT FINDINGS: Angiotensin-converting enzyme inhibitors are now a first-line therapy for patients with type 1 diabetes and diabetic nephropathy, whereas in patients with type 2 diabetes, angiotensin II receptor blockers(ARBs) have been shown to protect the kidney." Type 2 Diabetics, heads up.
The effect on blood sugar makes more sense when you appreciate steroid hormones are involved as in the Renin Angiotensin Aldosterone System.
