" The bottom line is that insulin use creates a vicious cycle that cuts years off a person’s life. Insulin both blocks cholesterol removal and delivers cholesterol to cells in the blood vessel walls, increasing the risk for heart attacks and strokes. Almost 80 percent of all deaths among diabetics are due to hardening of the arteries, particularly coronary artery disease. Many diabetics turn to their physician for guidance, but oftentimes the well-meaning doctor only worsens the problem by prescribing more insulin. The extra insulin does not just cause heart disease, weight gain, and the eventual worsening of the diabetes; as with type 1 diabetes, insulin can increase the risk of cancer as well. Type 2 diabetic patients exposed to insulin or sulfonylureas, which push the pancreas to produce more insulin, have significantly increased incidence of cancer at multiple sites. "
