„Salt only harms people who already have high blood pressure.”

The SSaSS trial (2021, n=20,995, 5 years) replaced 25% of table salt with potassium chloride and cut stroke 14% and mortality 12% across an entire village population — not just in hypertensives. The blood-pressure response varies (salt sensitivity), but the risk curve is continuous even below 120/80. European intake is 8–11 g a day against a 5 g recommendation; 80% comes from processed food, not the shaker.
