Insulin Protects Against Artery Damage

Insulin Protects Against Artery Damage: Joslin researchers have produced clear evidence that insulin, long suspected of worsening artery damage in patients with diabetes, instead protects blood vessels. The evidence "suggests that if you can improve insulin action in endothelial cells, you may be able to slow or prevent atherosclerosis." The finding suggests that physicians should not be so wary of prescribing insulin to patients with diabetes. See this week's Item #9.
