Can Salt Substitutes Lower Blood Pressure in Diabetes? A Cochrane Review

With global hypertension and diabetes rates increasing, researchers are exploring alternative solutions for managing blood pressure effectively. One promising area is the use of salt substitutes.

The Cochrane Review: A Deep Dive

A new Cochrane review aims to systematically evaluate whether replacing regular sodium salt with alternatives like potassium or magnesium salts can help lower blood pressure in adults with diabetes. The review's protocol outlines a rigorous plan to evaluate blood pressure effects, safety, and adherence using data from Randomized Controlled Trials (RCTs) and quasi-RCTs.

Why Salt Substitutes?

The study investigates whether switching to potassium- or magnesium-based salts can help manage blood pressure without sacrificing taste or adherence. This is crucial for long-term compliance and effectiveness. Sodium reduction is a commonly prescribed strategy to lower blood pressure, however it is often difficult to maintain as it impacts the enjoyment of food.

Key Considerations: Safety and Adherence

Beyond blood pressure reduction, the review will also focus on:

• Safety: Assessing potential risks associated with potassium and magnesium intake, especially for individuals with kidney issues.
• Adherence: Evaluating how well participants stick to using salt substitutes long-term.

What's Next?

The results of this Cochrane review could provide valuable insights for clinicians and individuals with diabetes looking for effective and sustainable ways to manage their blood pressure. Read the full article here.
