Summary
Brief summary
Despite the recognised association between salt intake and blood pressure, there have been no studies documenting salt consumption in patients with type 2 diabetes. We hypothesized that the majority of patients with type 2 diabetes may not comply with the recommended guidelines for sodium intake.
