Surprising Findings

The salt substitute reduced death rates by 12% without increasing hyperkalemia, despite adding potassium chloride.

Many assume extra potassium is risky for older adults, especially those with hypertension or kidney issues—this study directly contradicts that fear with large-scale data.

Practical Takeaways

If you're over 60 and have high blood pressure or a history of stroke, consider switching to a potassium-enriched salt substitute (75% NaCl, 25% KCl) in home cooking.
