Salty Diet and Heart Disease in Type 2 Diabetes

Too much dietary salt is not good for people with type 2 diabetes, since it boosts one's risk of developing heart disease. Specifically, for people with hemoglobin A1C levels of at least 6.5 percent, every 1 gram per day increase in salt was linked with a 20 percent higher risk of heart and vascular disease.

That's the primary finding of a recent study by Hirohito Sone, MD, PhD, of Niigata University in Japan and colleagues. Their results support current guidelines for patients with diabetes, and reducing salt intake among type 2 diabetics does bring health benefits, even if researchers remain uncertain about the exact relationship between salt intake and complications with diabetes.

The researchers examined data from almost 1,600 patients over eight full years of follow-up in the Japan Diabetes Complication Study. This prospective study was intended to explore the incidence of, and risk factors for, macrovascular and microvascular complications of diabetes.

On the plus side, researchers could find no association between dietary salt intake and elevated risk of other diabetes complications, such as nephropathy or diabetic retinopathy.

The study found that too much dietary salt has been linked to a higher risk for heart and vascular disease in Type II diabetics.
