By 1982, salt was called ‘A New Villain’ on the cover of TIME magazine. The 1988 publication of the INTERSALT study seemed to seal the deal. This massive study involved 52 centers in 32 countries and laboriously measured salt intake and compared this to blood pressure. Across all populations, the higher the salt consumption, the higher the blood pressure. Seemed like a slam dunk, although the effect was quite small. A 59% reduction in sodium intake would be predicted to lower the blood pressure by only 2 mmHG. If your systolic blood pressure was 140, severely restricting your salt could lower that to 138. However, no data existed as to whether this would translate into less heart attacks and strokes. But based on this influential study, in 1994 the mandatory Nutrition Facts Label proclaimed that Americans should only eat 2,400 mg per day (about one teaspoon of salt).

The dramatic improvements in health and lifespan of the last 50 years have occurred during a period where almost everybody was considered to be eating too much salt.
Our belief in the benefits of low salt consumption are largely based on mis-information and myth-information. The underlying assumption of the salt reduction advice…
